How to Resolve Your Merchant Center Errors - Once and For All!

    stencil.default (17)

     

    Google Merchant Center errors are one of the biggest obstacles for retailers in reaching online consumers with their products. Feed issues can span from basic mistakes (such as price mismatch or incorrect availability), to missing product data, all the way to processing errors. And if there’s one thing they all have in common, it would be a crippling effect on your ads.


    Keeping your data feed aligned with Google’s specifications is crucial to successful Shopping Campaign performance.

    Based on our experience working with product feeds for over 10 000 online shops, we’ve put together a guide to help you navigate through the most common Google Merchant Center errors and warnings.

     

    Why is the feed so important?

    Unlike Google Search Ads, Shopping Ads don’t get triggered by the keywords you choose to bid on.

    It is the product data included your feed, that helps Google decide whether your ad should be displayed or not.
    Your data feed is, in fact, the backbone of your Google Shopping Campaign:

    • it influences the relevancy of your ads
    • it’s a base for campaign segmentation

    How do I identify feed issues?


    Identifying and troubleshooting feed issues can be quite cumbersome at times. It gets much easier once you know where to look for key information.

    Let’s take a look at a few resources that can help us get on the right track with our product feed:

     

    DataFeedWatch - Feed Review


    Why fix the Google Merchant Center errors if you could avoid them in the first place?

    If you’d like to check your Google Shopping feed for potential errors prior to submitting products - here’s a way to do it! 

    DataFeedWatch Feed Review is a separate tab in your Channel Mapping Interface. Request a channel feed review, and verify whether product data you’re about to send to Google Shopping is complete.

    google-shopping-automatic-feed-review

    The review will check your feed for the following:

    • Missing data: are the required or optional fields populated with values?

    • Uniqueness validator: Do your unique identifiers, SKU, UPC, have duplicates?

    • GTIN validator:  this feature checks if your GTINs are valid

    • Pre-defined fields validator: this feature checks if fields with predefined values are mapped correctly


    feed-review-summary-datafeedwatch



    There is a list of affected items provided for each potential issue. This is accessible in the form of a summary and a downloadable report.

     

    fix-shopping-feed


    Google Merchant Center - Feed Upload


    The very first thing Google does once your feed is uploaded is to check for basic product data correctness. If issues are found, they will provide you with a brief report summarizing the errors.

    shopping-feed-processing

    Items that successfully pass this verification, will enter the next stage of the review process. The 2nd phase can expose issues undetected during initial processing.

    For a complete overview - refer to the Diagnostics section.

     

    Google Merchant Center - Diagnostics

     

    Diagnostics’ is a separate section in Google Merchant Center, accessible from the side navigation bar. It offers detailed issue reporting across your account & feeds.

    google-merchant-center-diagnostics

    Diagnostics show all the errors, warnings, and notifications that need to be addressed to make your products eligible for Google Shopping. Along with a full report on affected items, which you can download as CSV.

    Errors, warnings, and notifications

     

    When uploading your products to Google Merchant Center account, you might come across different kinds of feed issues. They could vary by severity - some issues might turn out fatal for your Shopping Ads (formerly Product Listing Ads or PLAs), some may represent an opportunity to improve feed quality.

    google-merchant-center-errors-details


    In order to help you prioritize issues - Google split them up into 3 types:

     

    ⇒  ERRORS

    Errors indicate critical feed issues. They lead to product disapprovals and, consequently, prevent you from showing ads of the affected items. In some cases, errors might result in account suspension and disrupt your marketing efforts for a longer period of time. 

    Bottom line - better stay clear of errors! And if you do get them, make sure to place them right on top of your priority list for fixing feed issues.

     

    ⇒  WARNINGS

    Warnings are less severe than errors, and typically don’t cause Google to reject your items.

    Those issues will negatively impact feed quality and decrease the performance of the affected items in your shopping campaign. 

    If warnings remain unaddressed for a long time, they might at some point lead to product disapproval or even account suspension.

     

    ⇒  NOTIFICATIONS

    You can treat the notifications simply as tips from Google. They let you know which parts of your product feed could use adjustments for better ad performance.

    It’s not required to follow these recommendations, but why say ‘no’ to a suggestion coming straight from the horse’s mouth?



    Now that we have clarity on what each type of issue indicates, let’s dig in and take a closer look at how to efficiently resolve some of the most common Google Merchant Center issues.

    The 35 Most Common Google Merchant Center Errors 


    Availability errors in Google Merchant Center

     

    Availability attribute issues have been known to cause headaches for advertisers over the years. The complexity of resolving them usually lies in unclear definitions of what triggered the Merchant Center error in the first place. Fortunately, the solution itself is often straight-forward.

     

    Availability field requirements

    Availability is one of the predefined Google Shopping feed fields, where you can only get 3 values in:

    In stock

    Out of stock

    Preorder


    Anything else, including values such as ‘available’ / ‘unavailable’ or ‘yes’ / ‘no’, is going to result in item disapproval.

     

    Why is it important to get the ‘availability’ field right?

    There are 2 important reasons why you should take proper care of your availability data:

    • Advertising limitations: availability errors lead to disapprovals, and availability warnings may contribute to getting your Merchant Center account suspended
    • User experience: wrongly assigned availability will confuse buyers and can deter them from visiting your web-store again



    Invalid value [availability]
    /or/
    Missing required attribute: [availability] 

     

    This error means you’ve either submitted a value outside of the accepted range or you’ve skipped the availability attribute entirely in your data feed.

    Probable cause: Several shopping carts generate availability fields containing values incompatible with Google’s guidelines. For example, some platforms may be labeling products with ‘true’ or ‘false’ within the ‘is_available’ field.

     

    How to fix it?

     

    Make sure you have one of the 3 availability options assigned in your shopping feed: in stock, out of stock, or preorder. You may continue using the availability field from your store, only with a small modification.

     

    Method 1: In your DataFeedWatch feed, go into ‘Edit Values’ for the ‘availability’ attribute and overwrite the values. Here’s how an example rule might look:

    fixing-availability-error-shopping-feed

    Tip: If you’re unsure what values were originally submitted that caused the error:

    or

     

    Method 2: Use ‘quantity’ input field and build conditional statements to specify availability. An example below:

    setting-up-availability-shopping-feed

    Unclear value on your website [availability]

     

    This is a relatively new error that started appearing in Google Merchant Center around the time of introducing free product listings to the shopping tab (April 2020). It’s hard not to tie it with Google’s aim to improve the experience for the searchers as it gears up for an eCommerce war with Amazon.

     

    Probable cause: Availability is not visible on your landing pages or your structured schema markup requires fixing.

     

    How to fix it?


    Step 1:
    Verify that availability is visible on your website landing page AND included in your structured data markup. To verify whether your schema markup contains the right data, you may use a structured data testing tool from Google or Rich Results Test.


    Step 2: Depending on the results of your check:

    • If schema markup or your landing page is missing availability info - you need to have your website developer or the SEO-responsible add it.
    • In case you’ve verified that both are in order - the blame might be on Google’s glitch. Going through Google’s support team should get this error wiped and products approved.

    Automatic item updates active [availability]

     

    This warning informs you that your product’s availability data got updated by Google due to discrepancy between the feed and your online shop data. This is only possible if automatic item updates are enabled in your Merchant Center account:

    automatic-update-gmc-price-availability

    The good news is: your products' stock status got fixed, which allows you to continue advertising affected items.

    The bad news is: if these warnings continue to occur it may lead to products disapproval or even account suspension at some point. 

    automatic-updates-active-availability

    To implement a long-term solution it’s important to recognize the underlying issue, which is that your feed update frequency may not match the dynamic turnover of your store.

     

    EXCEPTION: In some cases, the “Automatic item updates active [availability]” warning may be caused by incorrect availability microdata. In this scenario, your data feed contains the correct values, but the structured data markup on your website contains the wrong ones.

    As a result, Google is overwriting availability with incorrect information.

    In this case, you should fix your structured data markup. You can also temporarily disable Google automatic updates to stop it from overwriting values until you have the microdata fixed.

     

    How to fix it?


    To resolve this warning, you need to ensure your data feed contains availability info at all times.

    Method 1: If your store inventory is subject to frequent changes it’s recommended to take advantage of the Inventory Update Feed. It will allow you to add an additional daily data fetch (or several if you're using the FTP method) that will complement the main product feed that is also granted 1 automatic daily fetch by Google. 

     

    To add this supplemental feed in DataFeedWatch simply select it from the list of available channels. Once ready, provide the feed URL in your Merchant Center account & set the daily update schedule.

    add-inventory-update-feed

    Important!
    Don’t forget to increase the frequency of data syncing between your store and the feed! After all, fetching old data to the Merchant Center a few times per day won’t solve the problem. You need the feed to carry updated data.

    updates-frequency-datafeedwatchfeed-update-shop-update-schedule-datafeedwatch

    Method 2: Instead of utilizing Inventory Update Feed you may also switch to FTP/SFTP feed uploads. That way your main product feed would be automatically pushed to Google Merchant Center every time it’s updated with new information.


    Before you’ll be able to submit your feed via FTP or SFTP you will need to create an FTP or SFTP account.

     

    You can achieve the same benefit by utilizing Content API for feed submission (requires a direct API connection with Google Merchant Center) to provide your product data. 

     

    Note: Just as in the previous example, ensure that your store update frequency is aligned with the updates of your feed in Google Merchant Center.

    Shipping & Tax errors in Google Merchant Center

     

    Shipping and tax errors you may encounter usually stem from providing insufficient data
    Although you may submit shipping and tax information via the main product feed, advertisers generally opt for setting it up directly in the Google Merchant Center. That way the set-up is applied account-wide, as opposed to being tied to a single data feed file.

     

    Missing shipping information

     

    You will see this error if you’ve neglected to provide your shipping rates to Google. It’s a required attribute for all Merchants, no matter the location or vertical. It also applies to retailers offering free shipping.

     

    How to fix it?

     

    Provide your shipping price and country.


    Method 1
    : via the data feed

    You can quickly add shipping information to your feed in DataFeedWatch - navigate to ‘Edit Feed’ and scroll down to the ‘Shipping’ section. Then, specify location and cost.

    • With a flat shipping fee, you can use a simple ‘add static value’ rule:

      add-shipping-data-feed


      If you offer free shipping make sure to enter 0.00, and not ‘free.

     

    • If your shipping price varies depending on other factors, e.g. product weight (and you determine your shipping price), the rule could look like this:
      shipping-error-fix

     

    Method 2: directly in the Google Merchant Center (GMC) account

    You can always set up your shipping rates in the GMC account. This allows you to apply shipping settings globally - to all the feeds held under your account. Also, if your shipping rates are dynamic and calculated by the shipping carrier - you will have to use this method to provide your shipping details.

    Click the tools icon > Shipping and returns > Click the + sign > Fill in the needed fields.

    Here you can find further instructions from Google on this process.

    Tip: If your shipping rates are calculated based on package weight, you will need to add an additional ‘shipping_weight’ field to your data feed. Read more about it below.

     

    Back to top or Get started with feed optimization - 15-day Free Trial


    Missing 'shipping weight' attribute

     

    This error often occurs after you’ve just changed your feed to a new one. Creating confusion among merchants who had previously set-up their shipping rules & had them running smoothly. 

    The issue may appear to you in the Merchant account as ‘Missing shipping weight’, or even ‘Missing shipping information’. 

     

    Probable cause: Your Google Merchant Center shipping rules are set-up based on product weight, and your feed doesn’t contain the ‘shipping_weight’ attribute. 

     

    How to fix it?

     

    Step 1: Go to additional fields in the Edit Feed section and select the ‘shipping_weight’ field.

    Step 2: Map it with a proper field from your shop data.
    Ah, and don’t forget to add the measurement unit (g, lbs, kg)!

    Step 3: Re-fetch your feed in Google Merchant Center and it’s fixed.

    Tip: If you’re using Shopify, the ‘grams’ field is what you’re looking for.

    Too few subattributes for attribute: shipping

     

    This error occurs if you haven’t specified both of the required attributes for shipping: price and country.

     

    How to fix it?

     

    Add all the necessary data. You can do it through the data feed or by navigating to the Merchant Center shipping tab and completing the shipping details there:

    Tools icon > Shipping and returns > Click on the shipping service name to edit it

    Opting for the latter gives you the benefit of applying your shipping settings account-wide.

    Missing value [tax]
    /or/
    Too few subattributes for attribute: tax

     

    Tax information is only required and allowed if the targeted country is the US. If you’re seeing this error, it means that the tax was skipped when you submitted your product data. Or, not all of the required tax values have been specified.

     

    How to fix it?

     

    Add tax rates either through your feed or via the Tax tab in the Google Merchant Center.

    In the Merchant Center: Tools and settings menu > select Sales tax > click the Tax Settings tab > Add tax information accordingly

     

    In the feed: go to ‘Edit feed’ and scroll through the mapping interface to the Shipping and Tax section. Then insert the proper rates. 

    add-tax-shopping-feed
    We recommend setting up the Tax information directly in the Merchant Center account - that way they are applied account-wide.

    Unique Product Identifiers (GTIN / MPN / Brand) errors

     

    Roll up your sleeves! These errors should be resolved promptly as they have a significant (negative!) impact on your Shopping Campaign performance.


    Google uses UPIs (Unique Product Identifiers), especially GTIN, to better understand and classify your products. Let’s zoom in on what that means for you if you provide correct & complete identifiers:

    • Shopping Ads showing for more relevant searches (which equals increased Conversion Rate)
    • Higher Quality Score (which helps you save up on CPC)

     

    Read more about the role of GTINs and how to get a GTIN here.


    Limited performance due to missing identifiers [gtin, mpn, brand]

    /or/

    Limited performance due to missing value [gtin]

     

    This issue occurs in the form of a warning in Google Merchant Center. Affected products are still eligible to show among Shopping Ads, but their performance is negatively impacted. The ‘limited performance’ may express itself through lower ad rank, being excluded from ‘Compare by store’ feature (introduced along with free product listings), and other disadvantages.

     

    In September of 2019, Google loosened its UPIs (Unique Product Identifiers) policy, making them [GTIN, Brand, MPN] optional for Google Shopping. However, items with identifiers provided are given higher priority, compared to items without submitted identifiers.

    The ‘Limited performance due to missing identifiers [gtin, mpn, brand]’ warning came to life as a result of this shift, replacing the error of ‘Missing two out of three attributes [GTIN, Brand, MPN]’.

     

    • ‘Limited performance due to missing identifiers [gtin, mpn, brand]’ will occur if your items are missing more than one identifier

    • ‘Limited performance due to missing value [gtin]’ will occur when you’re missing this one specific identifier.

     

    How to fix it?

     

    Provide Google with your product identifiers. Here’s how you can include GTINs in the feed:

    Method 1: Match the GTIN attribute with a corresponding field from your store. Depending on your shopping cart, it might be ‘barcode’, ‘UPC’, ‘GTIN’, or something else. A simple ‘Rename’-rule will be enough.

    gtin-barcode-shopping-feed

    Method 2: If your data source doesn’t contain GTINs, you can still provide them using a ‘lookup table’:

    In a csv file or a Google Spreadsheet fill in 2 columns:

    • The 1st column should contain an attribute that could be used for item identification in DataFeedWatch. Good choices might be variant_id, SKU, mpn.
    • The 2nd column will contain the unique GTIN per item.


    Connect the prepared file in DataFeedWatch & specify which attribute you’ve chosen to match GTINs to products. Voila!

    Invalid value [gtin] 

    /or/ 

    Ambiguous value GTIN 

    /or/ 

    Unsupported value reserved or restricted [gtin] 

     

    Google verifies all the GTINs submitted and will notify you if yours are incorrect. Let's take a look at what each error / warning means:

     

    Invalid GTIN

    GTIN submitted is incorrect. It might be a matter of additional, especially non-numeric characters in the product code. The only way to verify that would be to check the affected items in Google Merchant Center Diagnostics. If the GTINs seem alright to you, try contacting the manufacturer to request an up-to-date list of GTINs. 

     

    Ambiguous GTIN code 

    Google cannot recognize the GTIN submitted as it might have too many or too few digits. Global Trade Item numbers are usually 8, 12, 13, or 14-digits long.

     

    Reserved GTIN

    The GTIN you submitted hasn't been released for use yet by GS1. It’s reserved for future use.


    Restricted GTIN

    The GTIN you’ve submitted is invalid because it has one of the following prefixes: “2”, “02”, or “04”. These product codes are restricted for special purposes and internal systems, therefore cannot be used as a GTIN attribute for Google Shopping.

    If you have any doubts about the GTINs you have at disposal, you may find the GTIN Validation Guide useful.

     

    How to fix it?

     

    The instructions given below apply to fixing GTIN settings in your data feed. If you don't have correct GTINs at your disposal you should contact the manufacturer or get in touch with GS1

     

    Various mapping functionalities in DataFeedWatch can help you get your GTINs in order.  Let us consider the 2 most common examples:

    Example 1:

    If GTINs contains additional characters, eg. letters which shouldn’t be included - remove them in ‘Edit values’. Enter the exact characters you wish to remove or use a regular expression if appropriate.

    fix-gtin-error-google-merchant-center

    The above rule would remove any letter-characters present in the GTIN field.

     

    Example 2:

    Thirteen-digit EAN codes usually start with a 0, perhaps you’re missing it for some products? You can add a prefix to any GTIN that doesn’t start with a 0:

    Incorrect value [identifier exists]

     

    Incorrect value for ‘identifier_exists’ can mean a few things:

    1. Value outside of the predefined range: you’ve submitted a value outside of the accepted range (True/False) 

    2. Falsely ‘false’: you’ve marked this attribute as ‘FALSE’ but Google recognized the items submitted as products with existing identifiers

    3. Falsely ‘true’: you’ve submitted ‘identifier_exists’ as ‘TRUE’ for items that don’t have identifiers

     

    Considering that this product attribute is set to TRUE by default (even if you don’t include it in your feed) - scenario #3 is the most likely of all.

    'Identifier_exists’ attribute tells Google whether universal identifiers (brand, GTIN & mpn) are available for your products. Accepted predefined values are: ‘false’ / ‘no’ and ‘true’ / ‘yes’.  And heads up - chances are you’re not gonna come across this attribute in your feed (if not included in the feed, it defaults to 'true').

     

    How to fix it?

     

    Scenario 1: Value outside of the predefined range

    Correct your feed mapping to include only the allowed values (True or False). Using ‘add static value’ mapping type will come in handy here:

    set-identifier-exists-shopping-feed

    Scenario 2: Falsely ‘false’ 

    If you don't have product identifiers, but they do exist, don't mark the 'identifier_exists' field as 'false'. Google will find out anyways and return an error. Instead, you should keep the ‘identifier_exists’ attribute set to ‘true’ and simply not submit identifiers (GTIN, brand, mpn) if you don’t have access to them.

    Jump to error Limited performance due to missing identifiers [gtin, mpn, brand] to find out why it’s recommended to obtain product identifiers.

    Scenario 3: Falsely 'true'

    There are certain products groups for which identifiers don't exist, those would be:

    • products you’re the only seller of
    • vintage items
    • custom-made goods

     

    For those cases, set the 'identifier_exists' feed attribute to FALSE. Also, don’t submit any of the following attributes: brand, mpn, GTIN. Here’s how the set-up could look like:

    • Select ‘identifier_exists’ from ‘Optional fields’ and assign a static value of ‘FALSE’.

    identifier-exists-false-merchant-center

    • Make sure that brand, GTIN &  mpn are not included in the feed. Remove them completely from your feed or use the ‘leave empty’ option.

    fix-identifiers-merchant-center

    Note: Submitting any one of the identifiers while ‘identifier_exists’ is set to FALSE trigger another error: ‘Product identifiers provided, but ‘identifier_exists’ set to false’.

     

    Back to top or Get started with feed optimization - 15-day Free Trial


    Product identifiers provided, but ‘identifier_exists’ set to false

     

    As mentioned above (see error Incorrect value [identifier exists]), the ‘identifier_exists’ field informs Google whether your items have the unique identifiers. The error means that you’ve submitted at least one of the above attributes while informing Google that your products lack identifiers (‘identifier_exists’ = false). As those are contradictory information - you receive the error.

     

    How to fix it?

     

    Adjust ‘identifier_exists’ and relevant attributes:

    Method 1: If identifiers are available for your products, change the ‘idetifier_exists’ value to TRUE.

    Ensure you've mapped product identifiers such as Brand & GTIN or Brand & MPN for your items.

     

    product-identifiers-gmc-set-up


    Method 2
    : If brand, mpn or GTIN was submitted by mistake or containing invalid information - remove those fields from your feed, or change mapping type to ‘leave empty’.

     

    Method 3: If you have a mix of custom made items AND products with identifiers, you can configure your feed properly through conditional mapping. Here’s how the rules could be structured for individual fields:

    Identifier_exists:

    identifier-exists-possible-confuguration‘Brand’:

    brand-feed-set-up-indentifiers

    ‘GTIN’ & ‘mpn’:

    Match them with appropriate attributes from your store, without additional ‘IF statements’.

    Price & Sale Price errors in Google Merchant Center

     

    Common price errors in Google Merchant Center include lack of currency, incorrect formatting, and submitting free products (e.g. samples) with your Shopping feed. The solution is usually quick and straight-forward. Let's dig in!


    Missing or incorrect required attribute [price]

     

    Price has always played a key role in the success of Shopping ads. Now, with the new ‘Compare by store’ feature introduced along with free advertising on Google Shopping, it only gains in importance. 

    Probable cause: There are 2 possible reasons why you received the Missing or incorrect required attribute [price] error:


    • You haven’t assigned the currency (especially if it’s accompanied by another error: ‘Unsupported currency in attribute price’)
    • You provided no price or incorrect value for price

    How to fix it?


    Scenario 1: Missing currency or incorrectly formatted currency

    You may have sent over the correct prices, but including the currency is just as important. To specify the currency in the feed proceed to ‘Edit values’, and use ‘add a suffix’ option.

    Remember to include the currency code (USD) and not the symbol ($).

     

    currency-error-gmc-fix

    You may also assign currency directly in Google Merchant Center, in the feed settings section:

     

    setting-currency-merchant-center-feed



    Scenario 2: No price provided or incorrect value for price

    It’s a common misbelief that Google displays ‘Missing or incorrect required attribute [price]’ error due to discrepancies between the prices provided and those found in your online shop. These would result in issues such as Mismatched [price] (page crawl) or Automatic item updates active [price].

     

    ‘Missing or incorrect required attribute [price]', being one of the initial error messages you receive upon uploading your feed, is connected with not fulfilling Google’s basic requirements for the price attribute.

     Unsupported price values include:

    • 0.00; 
    • blank field;

    Here’s how to correct your mapping for the ‘price’ feed attribute:

    If the feed contains items offered for free at your store:

    The solution would be to exclude them. You may do so in the ‘Include/Exclude products’ section by setting up a rule based on price:
    exclude-products-from-feed

     

    If you’re missing the price value for some of your products:

    It’s worth checking further. Perhaps you’ve initially chosen the wrong ‘price’ field from your shop system. For example, ‘sale_price’, which is only populated for items that are on sale at any given time.

    Identify the right field from your source and make sure you’ve assigned it to the ‘price’ attribute.

    correct-price-mapping

    Invalid value for category [price]


    This one is quite similar to the previous error we covered. If you see it in your Merchant Center account, you might have used the wrong source field for the ‘price’ attribute. Many shopping carts have multiple fields for pricing, such as ‘price’, ‘retail_price’, ‘special_price’, ‘compare_at_price’, it’s not hard to get confused as to which one you should use. 


    How to fix it?


    In DataFeedWatch, you can review all the price fields we downloaded from your store in the ‘Shop products’ section and pick the one with correct pricing.


    correct-price-mapping



     Then, in the mapping panel, assign the selected price field.

     

    Back to top or Get started with feed optimization - 15-day Free Trial


    Invalid price format [sale price]


    Invalid price format usually refers to prices submitted with a comma instead of a dot (as a cent-delimiter) or with too many decimal places.


    How to fix it?

     

    Use simple recalculate rules to round your prices to max. 2 decimal places. You can do it in DataFeedWatch by visiting the ‘Edit Values’ for price:

    fix-price-formatting-shopping-feed

     

    In case the issue lies in the incorrect use of commas and dots in the price field, you can easily replace them:

    correct-price-formatting-shopping-feed

    Automatic item updates active [price]

     

    Automatic updates for price warning informs you that your product’s price data got updated by Google due to discrepancy between the feed and your shop data. That is because you have automatic price updates enabled in your Merchant Center account.

     

    • The good news is: the price on your listing got fixed which allows you to continue advertising affected items. 
    • The bad news is: if these warnings continue to occur it may lead to account suspension at some point. 

     

    How to fix it?

     

    Apply analogical solution as the one we described before, under Automatic item updates active [availability] warning.


    Mismatched [price] (page crawl)

     

    Mismatched prices is a critical error you will get if your products' prices in the feed are not the same as your prices on the website. Here are some possible reasons for product disapproval:

    1. You don’t have ‘Automatic item updates’ for price enabled in your account:
      automatic-update-gmc-price-availability
      Hence, Google can’t simply update your prices and serve you a warning like in case of the previous issue we covered (see above).

    2. You’ve received the ‘Automatic item updates active [price]’ warning too many times and it has now turned into an error.

     

    How to fix it?

     

    To fix the issue, you will need to identify what the root of the problem is. Checking the affected items in the Merchant Center Diagnostics usually helps.

    1. Is it that your prices change a few times per day? 

    If so, the best solution might be to increase data update frequency in Google Merchant Center. (For that to work, don’t forget the data feed also needs to be synced with your store frequently).

    1. Maybe you’ve used the wrong price field from your data source?

    Correcting the price mapping might help.

    1. Perhaps it’s your structured data markup that holds the old price data?

    This could be misleading for Google and end up in product disapproval. More about tackling this issue here (it can be resolved analogically to the ‘incorrect availability microdata’ issue)

    Description-related errors

     

    Another area in which Google recently decided to set the bar higher (likely in relation to introducing free Google Shopping ads) is the ‘description’ attribute. Starting from September 2020 the ‘description’ field becomes required for all products. Although products without descriptions will be eligible to display, they will be given lower priority. 

    And we all know what that means - lower ad performance.

     

    Missing value [description] /or/ Text too short [description]

     

    Your feed is missing the ‘description’ completely or the one you submitted is too short. While Google only specifies the maximum character count (5000) for a product description, with no mention of the minimum length, it’s safe to assume it should be longer than the product title. Otherwise - you’re likely to be served with the warning.

     

    How to fix it?

     

    Method 1: If you have a long description in your source data - use it! You can even use a few different description fields depending on which one is available:

    fix-description-error-merchant-center

     

    Method 2: If you don’t have descriptions ready for your items, you can start by combining various product attributes to compose them. You may even customize it for different product groups:

    add-product-description-shopping-feed


    Method 3: Feeling creative and have some spare time?
    You can attach a fully-customized, killer description to each product (or maybe you’d like to do it for your bestsellers only?). The lookup table option will come in handy:

    write-product-descriptions-shopping-feedset-description-lookup-table-shopping-feed

    Encoding problem in attribute: description

    /or/

    Invalid UTF-8 encoding [description])

     

    This encoding error message in Google Merchant Center means that some of your descriptions contain 1 or more characters considered invalid in your current encoding setting. According to Google’s help pages, Google Merchant Center supports UTF-8, UTF-16, Latin-1, and ASCII encoding types. The first one being the most popular.

     

    Bad news?

    Google will only point out products that the error is connected with, it won’t serve you the invalid characters on a silver platter. It’s up to you to find the ones that triggered the issue.

     

    Good news?

    We’ve got you covered :)

     

    How to fix it?

     

    Once you’ve identified the products concerned, proceed to the ‘Shop Products’ page to review their descriptions. The default encoding setting in DataFeedWatch is UTF-8, so you should be able to detect those inaccuracies with the naked eye.

    Then, proceed to the mapping section and remove or replace the unwanted characters in the ‘Edit Values’ section for descriptions.

    Image-related errors in Google Merchant Center

     

    Your Shopping Ad product image is the first impression you make on shoppers. Make sure it’s a good one! 

    Google will help by verifying the quality of the images you submit.

    • Is the image big enough?
    • Is it high quality?
    • Are there any distractors present in the form of text overlay?

    These are just some of the quality factors Google will check for when you submit your product feed. Now, let’s look at a few common image-related errors and how to get them fixed.

     

    Promotional overlay on image [image link]

     

    Google has strict rules about including promotional overlay in your Shopping Ads images. And the rule says - no promotional overlay. If you’re seeing this error, there are a few potential solutions you could consider.

    PS: You can learn more about how to optimize your Shopping Ads images in one of our previous articles.

     

    How to fix it?

     

    Depending on how many product images you have at hand and which of them are actually eligible to serve on Google Shopping, the solution could differ:

     

    Method 1: Use Google’s ‘Automatic Image Improvement’ feature


    As this is a new option in Google Merchant Center (GMC), not all GMC users have discovered its existence. All you need to do is enable the image improvement tool in your account and let Google do its magic. It will remove the promotional texts from your images.


    automatic image improvement-merchant center

     

     How to set up the feature?

    1. In your Merchant Center account, select ‘Automatic Improvements’ from the Tools dropdown
    2. Confirm ‘Enable automatic image improvements’ and save

    automatic-image-improvement-gmc

    This is an opportunity for a zero-effort fix, but keep in mind - machines don’t always get it right. Check the updated image - if the system’s attempt to improve it fails (for example promotional text is only partially removed), you’ll need to upload a new image.

     

    Method 2: Change image assignment

     

    If you have multiple product images for your products in your online shop, one of the easiest ways to get rid of the error would be to select another image. One that is in line with Google’s image requirements for Shopping Ads

    Instead of using your primary image for all products, you could switch, for example, to the 3rd product image. You can make that change for all products or exclusively for those affected by the error.

     

    In your mapping panel in DataFeedWatch, navigate to the image attribute setting and match it with another image in your source data:

    change-image-shopping-feedThe example rule in the screenshot above is set to change image assignment only for products affected by the image error. To let the system know which products have been affected by the error you could use a list of SKUs / IDs / GTINs of rejected items. CSV or TXT file, or a Google Spreadsheet will do fine for this purpose.

     

    Method 3: Create new images

     

    This one is pretty straight-forward. Your product images got rejected. If you can’t fix the issue using method 1 or 2, mentioned above, you will need to arrange for new product images that will be in line with Google’s guidelines.

    Once you have them ready, revisit the mapping section of your feed and assign image links properly (see example above). In the meantime, if you wish to keep your account error-free, you can exclude the disapproved products from the feed.

    For this purpose, you could utilize an exported list of rejected items. More on how to leverage lists in your product feed here.

    Image too small /or/ Low image quality [image link]

     

    Google’s minimum size requirements for product images sit at 100x100 pixels, and 250x250 for products within the clothing & apparel category. If your images don’t fit that description you will need to provide Google with new ones.

    If up until now you were quite certain of the good quality of your images - maybe your product feed is not properly mapped. For example, it pulls the smaller images from your store, instead of the full-size quality images you have.

     

    How to fix it?

     

    First, it’s important to verify whether the images you can see the error for in your Merchant Center account are available in a larger size. Start by checking the affected items in the error report.

    If those images are available in bigger size:

    Review your feed mapping and make sure you assign the right source field from your store.

    For example, for Shopify store owners the main product image comes in a few sizes: small, medium, large, grande and thumbnail. The biggest version is usually located in the ‘image_1’ field. That’s the one you should use. 

     

    If they aren’t available in bigger size:

    If the biggest size of the given image is already uploaded to Google Merchant Center, try following the same solutions as for the ‘Promotional overlay on image [image link]’ error:

    Incorrectly assigned Google Product Category

     

    This isn’t the type of error you’re gonna see in the Merchant Center Diagnostics. Rather, it’s something you can discover yourself when reviewing the product list in Google Merchant Center. 

    The taxonomy is crucial for the product ads as it helps Google to identify if your products are a good match for a given shopper query. Product categorization used to be the merchant's task until recently. Today, Google conducts automatic category assignments.

     

    With this new development there comes a risk of getting your products categorized incorrectly. The repercussions could include: 

    • serving your ads to the wrong audience
    • Google wrongly enforcing additional attributes on you (e.g. color, size, or age_group for products outside of the apparel & accessories range) 
    • tax-related issues, if you’re targeting the U.S.

    That’s why we recommend keeping an eye out for any miscategorization and fixing it as soon as you spot it!

     

    How to fix it?

     

    Say you’ve identified that your purifying skin masks collection got categorized as ‘protective medical masks’. Now, you probably won’t be getting many sales out of serving these ads.

    Fortunately, Google allows you to overwrite the automatically assigned value. And, there’s an easy way to assign the right categories in DataFeedWatch, or even two:

     

    Method 1: Categorization via auto-generated rules:

    easily-assign-google-category-2

    We have created a system to match each product type to the most appropriate Google subcategory, in a matter of seconds:

    Step 1: Choose a field from your store containing product type information,

    Step 2: Start typing in a keyword & you will receive a list of categories to choose from,

    Step 3: Select a proper Google category for each item group.

     

    Method 2: Categorization via manual rules

    Handy if your source feed is lacking a field to base the categories on. To add a category, proceed as follows:

    Step 1: Start typing in a keyword and select the best category match from the list.

    Step 2: Create rules to specify the products the category should be applied to.

    Example: You can assign categories based on certain keywords that could be found in titles or descriptions:

    override-wrong-categorization-google-shopping

     

    What is the right category for my product?

    The most relevant one. All in all - it would be a judgment call.

    Tip: Dive into the subcategories and be as specific as you can. With over 6000 unique Google categories it’s usually possible to find an exact match. If not - the rule of thumb is to go with the closest match. We’ve covered Google Product Category in-depth in one of our previous articles.


    Invalid or missing required attribute [color]

     

    There might be 2 reasons you’re receiving this error:

    Google cannot recognize the color name

     

    According to one of the local radio hosts, most men can only tell apart 2 colors, and those would be: pretty and ugly ;)

    Luckily for the advertisers, Google is quite good at recognizing colors. Cobalt, indigo or even blueberry are rather safe choices. But, don’t get carried away with creativity - ‘pomegranate passion’ may be one step too far. Fancy color names may be exactly what is causing this error.


    How to fix it?

     

    First, check the Google Merchant Center error report for a list of color names that need to be fixed. A recommended practice is to use colors in your feed that a user would search for. For example the ‘pomegranate passion’ could become simply ‘red’.

     

    Replacing invalid color names:

    In the mapping panel - navigate to ‘Edit Values’ to replace the invalid values.

    If you only have a handful of colors to replace you might want to use ‘replace single value’ and create a few rules, just as in the below screenshot:

    fix-incorrect-colors-1

    To replace many colors in bulk - go for ‘replace multiple values’: you will need to provide a csv file, or a Google spreadsheet. Include the rejected color names in 1st column and their standardized equivalents in the 2nd column.

    replace-colors-data-feed

    Side note: when uploading a Google spreadsheet to DataFeedWatch, please make sure to use the shareable link & set the privacy of the sheet to ‘anyone with the link can view’.

     

    No colors provided for apparel items 

     

    For certain countries (currently Brazil, France, Germany, Japan, the UK, and the US) Google requires additional information for apparel items. This may be color, age_group, gender and size.

    It might be that the error ‘Invalid or missing required attribute [color]’ occurs because products that were recognized by Google as clothing & accessories are missing the ‘color’ attribute in the feed.

    Tip: If you don’t have any apparel products and haven’t submitted color info for your products - check out the incorrect Google Product Category error.

     

    How to fix it?

     

    Assign colors to apparel items. If you’re missing the color field in your source file/store - you can try one of the following options:

     

    • Use ‘Add static value’

      Are colors mentioned in titles, descriptions, tags or some other field?

      You can use those fields to build out a rule that will assign colors, specified by you, to appropriate items. Here’s an example of how the rule may look like:

    add-missing-colors

    • Use ‘Extract from’ 

      ‘Extract_from’ is another functionality allowing you to extract specific information from various fields. First, indicate the field that contains the color info (A), then provide a list of colors in a csv file or using a Google spreadsheet.
      When creating the list make sure that the color names you include are exactly as they appear in your source.

    Missing additional product data errors

    [gender, color, age group, size]

     

    For certain countries, Google requires additional information (gender, color, size, age_group) to be provided within the feed if you’re selling fashion-related goods. Failure to produce them results in product disapproval.

    • Missing required attribute [gender]
    • Missing required attribute [age_group]
    • Missing required attribute [size]
    • Missing required attribute [color]

    These all are examples of Apparel & Accessories category related errors. Although they are separate errors, they often come together as a ‘package’. 

     

    If you don’t sell any products that could be classified as ‘Apparel & accessories’ and you are seeing these errors, chances are your products got miscategorized. Check the Incorrectly assigned Google Product Category error.

     

    How to fix it?

     

    The error(s) will go away as soon as you provide the required information. Let’s do a quick run-through:

     

    Gender

    In this case you only get 3 values: ‘female’, ‘male’, ‘unisex’. You could either match this feed attribute with its equivalent from your store (if it exists), or set up appropriate conditional rules. Here’s how it could look like:

     

    add-gender-product-feed-google-shopping

     

    In case you already have a dedicated field in your data source specifying gender - a simple rename rule will work. If your dedicated field contains values outside of the accepted range, you can still pair it with the ‘gender’ feed attribute. You will only need an additional adjustment before pushing it to Google:

    assign-gender-data-feed

    correct-gender-mapping-data-feed

    Age_group

    Another Google Shopping attribute that comes with a set of predefined values. Those are:

    • ‘Newborn’ (Up to 3 months old)
    • ‘Infant’ (3–12 months old)
    • ‘Toddler’ (1–5 years old)
    • ‘Kids’ (5–13 years old)
    • ‘Adult’ (typically teens or older)

     

    To set it up in your product feed you can apply similar logic to the one described above for the ‘gender’ attribute. In case you’re only selling products for only 1 age group, the rule would look like this:

    assign-age-group-shopping-feed

     

    Size

    For a smooth shopping experience, follow the formatting guidelines of the country you’re selling in when assigning size. You can read more about size attribute requirements and best practices here.

    Usually, merchants go for matching their source field for sizes with the size attribute in the feed. Like in the screenshot below:

    assign-sizes-shopping-feedTip: If you’re with Shopify, you’ll likely be well-off using the ‘size_option’ field.

     

    Color

    When assigning colors - think of how your target audience is looking for products. What colors could they use in their search queries?

    We’ve covered several ways of adding missing color information to your feed in one of the previous errors in this article.

    Missing or invalid data [condition]

     

    The errors related to the product’s condition (new, used) are often thought to be incorrectly submitted ‘condition’ feed attribute. That’s hardly ever the case!

    If you’re seeing this error, it almost certainly means issues with your microdata on product landing pages.

     

    Condition data may be completely missing from your structured markup code, or it may state a value that is invalid e.g. ‘good condition’.

    microdata-1

    Google will crawl your website for automatic item updates and to better understand various attributes of your products (eg. availability, condition, price). Microdata helps Google detect mismatches between your product data and your landing page. This ensures accuracy of Shopping ads and helps prevent disapprovals related to outdated information in the feed. 

     

    How to fix it?

     

    Add microdata to your product landing pages. You may need a hand from our website developer or an SEO specialist to complete this fix.

    To verify whether your schema markup contains the right data, you may use a structured data testing tool from Google or Rich Results Test.

    Excessive capitalization [title]

     

    Note that this error applies exclusively to the product feed and not to your product landing pages. Your product titles in the product feed are capitalized and Google doesn’t like it. It’s specifically the use of uppercase that is triggering the error in your Merchant Center account. 

     

    • Product titles on your website can be capitalized to the extent that you want and Google won’t mind
    • The product title passed via the data feed needs to be de-capitalized

     

    In general, you are allowed to use capitalized words across your titles (even in the data feed) as long as it’s moderate. There are no clear boundaries in place, but let’s say having your brand name in uppercase while the rest of the title is composed of non-capitalized text should be fine.

     

    How to fix it?

     

    You need to get rid of excessive capitalization in your product titles that are passed via the product feed. There are a couple of approaches you could take:

     

    Method 1: Change capitalization in the feed, leave it be on your website.

     

    In DataFeedWatch you can easily fix your capitalization across the entire feed in a matter of seconds. All you need to do is visit the ‘Edit values’ section for the ‘title’ attribute and choose what you want to do:

    fix-excessive-capitalization-error-merchant-center

    • Capitalize: this option will apply a 1st-letter-uppercase rule. You can choose whether you’d like to apply this rule the entire title or maybe just parts of it. An exemplary product title would look like this:

    Adidas Honey Desert Sneakers, Blue, Size 38

     

    • Uppercase: text will be all capital letters. While you are straying away from capitalization to resolve the error, you could always choose to apply uppercase to specific parts of the title. For example - the brand name. Here’s how a product title could then look like:

    ADIDAS Honey Desert Sneakers, Blue, Size 38

     

    • Lowercase: if you apply it to the entire title, it would be devoid of any capital letters. For example:

    adidas honey desert sneakers, blue, size 38

     

    Depending on what your original titles looked like, you may need to apply one or more of these rules to get your title into the perfect shape. As you polish them up, you can always take a peek into the preview.

     

    Method 2: Change capitalization directly in your web-shop.

     

    Probably a more time-consuming method, but if you want to keep your titles the same on both the landing pages and in the feed - that’s the way to go. The store data is usually a live source for the product feed so any changes you make over there would carry over to your Shopping feed.

    Invalid or missing required attribute: id

     

    The product ID is your product’s transaction history and quality score information carrier. Without it your Shopping ads won’t run.

     

    How to fix it?

     

    Every product submitted to Google Shopping needs to own a unique ID in order to pass Google’s verification and be served among the Shopping ads results.

     

    Step 1: Identify which items are missing the ID value.
    You can do it by reviewing the report in Google Diagnostics, or checking out the Feed Products tab in DataFeedWatch.

     

    Step 2: Assign a proper attribute from your online shop.
    It should be a field that is populated, and unique, for all products. Popular choices would be SKU, variant_id, or a UPC.

     

    In DataFeedWatch you can review your shop items in a filtered view to easily identify the right field. If none of your ID fields is populated for all products, you can also populate this attribute using rules - for example by adding a static value or using a lookup table.

    CSS not selected for this destination

     

    This is a relatively new error and one not related to Shopping Ads. This error is all about the free product listings Google introduced this year.

     

    css-not-selected-error-google-merchant-center

    Probable cause: If you’re seeing this error it likely means you’re using a 3rd party CSS (comparison shopping service) to serve your Shopping Ads, AND you haven’t chosen that particular CSS to represent you in the ‘Surfaces across Google’ space. 

    Keep in mind you will only be able to select only one CSS partner to represent you for the free Google advertising space.

     

    How to fix it?

     

    First, some important context: 


    The changes to representation on ‘Surfaces across Google’ need to be done in the Google Merchant center account in which you’ve verified and claimed the domain

    It’s key to understand that any Merchant Account you have with 3rd party CSS is exempt from verifying a domain. Effectively, this means you have to set your representation for the free ad space through the Merchant Center that has Google Shopping as your CSS partner. 

     

    Solution: Make changes through the CSS Dashboard

     

    You can treat the CSS Dashboard as a 'control room' where you can manage opt-ins and opt-outs across all your CSSs for Shopping Ads. That’s where you will also select what CSS to use for 'Surfaces across Google' (separate from Shopping Ads).

     

    This dashboard is not available from within the Merchant Center (GMC) Accounts you have directly linked with the DataFeedWatch CSS (or any other 3rd party CSS for that matter). 

     

    • If you do have a GMC account directly with Google Shopping (as your CSS partner):

    In this scenario, you have at least 2 GMC accounts. One directly with Google Shopping, and one with a CSS partner. 

    Sign in to your Merchant Center account (the one directly with Google Shopping) > Click the tools icon > click Shopping ads setup under ‘Tools’ > Go to the CSS activity dashboard

    From there you will be able to select the CSS to represent you for ‘Surfaces across Google’ and the error should go away.

     

    • If you only have one GMC account, directly with a 3rd party CSS:


    You will need to register a new GMC account and claim & verify the domain in this new account. That way Google ensures that the changes come from a verified entity.

    You’re not required to upload any feed or run any ads from this additional account. It can simply work as a ‘shell account’ in order to manage programs such as 'Surfaces Across Google'.

     

    Once you have the new account, proceed as outlined in the example above.

    Feed processing errors/warnings in Google Merchant Center

     

    Offer quota full, items rejected

    This error could appear to you upon uploading a data feed to your Google Merchant Center account, and it will stop Google from verifying your feed for Shopping Ads.

    There are a few potential reasons you're seeing the error:

    • Google's internal error - the most probable reason for this issue.
      The solution would be to attempt the feed upload again with a several minutes break. Upon the 2nd or 3rd attempt, the error usually goes away and Google proceeds with the verification and approval process.

    • Too much data - your data feed file contains too much data. Try excluding a part of your product inventory and re-upload the smaller feed file to the Merchant Center.  Here you can check how to exclude products from a data feed in DataFeedWatch.

    • Too many data errors in your feed - a great part of your data feed contains errors. Try running a feed review first and resolving the errors before uploading your products again to Google Merchant Center.

    Item uploaded through multiple feeds (warning)

     

    It's recommended to only provide any unique product through one feed. If you upload the same item through 2 different feeds, you will receive a warning, but it won't cause product disapproval. Google will ignore the duplicate items in one of the feeds.

    To resolve the warning:

    • Remove the duplicate items from one of your feeds (find out how to remove specific items from your feed in DatafeedWatch in one of our other articles)

      OR

    • Change product IDs for duplicate items
      Google recognizes products by their unique ID. If you upload the same product twice, but with a different ID - it will be seen as 2 unique products. This solution is only recommended if you'd like to advertise the same item in a different set-up.

      For example, when you're conducting product title A/B testing, and one feed holds a different version of the product name than the other one. 

    Pending initial review /or/ Image not retrieved (crawl pending)

     

    This error generally turns out to be Google's internal delay. It doesn't indicate any issues with the images uploaded.

    The only solution in this case is to wait. If you continue seeing this error after 72 hrs, contacting Google Merchant Center Support is advisable.


    Incorrect feed URL

     

    If you come across issues, such as 'incorrect data feed URL' or 'error with processing data file', while submitting your product feed URL in Google Merchant Center, you've likely included additional characters in your feed URL, or used incorrect format.

     

    According to Google Shopping feed specifications, the data feed file should come in one of the following formats: text (. txt) and XML (. xml).

    If you've verified that the format is correct, try uploading the feed URL once more. Make sure there are no accidental spaces or other characters added.

    Item disapproved due to policy violation

     

    Unlike the other errors we’ve covered in this article - this one doesn’t give you clarity on what is wrong with your feed. If there is 1 conclusion to be drawn from the error message alone it would be that Google’s algorithms have found elements in your feed (or in your online store), which are not in line with Google Shopping policies.

    Which elements? That remains a mystery, until…you contact Google.

     

    To sort out this issue, you first need to learn the answer to the most fundamental question: ‘what was the policy violation on my part?’. Once you’ve established the exact reason for disapproval - it’s time to fix the feed (if that’s where the issue lies). Or, make suitable changes in your online store.

     

    Fixing the feed will mean different things depending on what the violation is. It might involve:

    • Removing products from the feed
    • Replacing or removing banned words from titles or descriptions
    • Changing images
    • And many more...
