Why Google Shopping Product Images are so Important
3 days after hearing information people are likely to remember only 10% of it. However, if a relevant image is paired with that same information, people retained 65% of the information three days later.
The challenge with online shopping is that people can’t touch or see the actual product. That’s why the role of images is enormous.
As shoppers are basing their purchasing decision on the image you need to outstand from your competitors somehow.
Grab attention with the image
The image is the largest part of the ad. Many customers typically decide on a product by looking at the following attributes with the following order: image, price, title. When in Google Shopping customers immediately drawn to an image and after that their eye line is drawn to the text.
In other words, the combination of images and text results with better campaign performance. The image is the most important component of your ad also because that’s the first thing shoppers can compare with competitors.
By selecting the right image you can tell shoppers something important about your product, service or brand. Shoppers Crave for Images as they are easy to digest.
Google’s Shopping Requirements for Product Image
If you want to be found in Google Shopping, there is a simple method: do what Google tells you.
Image Size Requirements
Both too small and too big images will cause an error on your Google Merchant Center account and your listing will not go live. Pay the highest attention to the size requirements that Google provides:
→ Non-apparel images: at least 100 x 100 pixels
→ Apparel image: at least 250 x 250 pixels
→ No image larger than 64 megapixel
→ No image file larger than 16 MB
Only the following formats are accepted:
→ GIF (.gif) (non-animated)
→ JPEG (.jpg/.jpeg)
→ PNG (.png)
→ BMP (.bmp)
→ TIFF (.tif/.tiff)
Requirements for the URL
It is important to remember that Google will look at images and their links using crawlers and an algorithm, therefore getting the URL right is essential. The URL requirements include:
Using the [image_link] category in your feed, the URL must link to the main image for the product.
→ The URL must start with either http. or https.
→ The URL must be in line with RFC 2396 or RFC 1738 - examples:
→ Space would be %20
→ A quotation mark (“) is %22
→ An octothorpe (#) is %23
They are not allowed aside from two exceptions:
→ Within the categories Hardware or Vehicle & Parts. Illustrations are allowed here where necessary.
→ Paint, in any category. With these products, single-color images are accepted.
What to Avoid with Product Images
- Text on the image
Since clear images of a product help to inform online shoppers, promotional text on ads is forbidden. If you want to add extra text, utilize the product description section.
- Broken links
Google must be able to read the link. If it can’t access the link, it won’t be shown, simple as that. Avoid adding spaces or other unreadable elements to your URL. Also, make sure you double-check the URL is still valid and hasn’t been moved or removed altogether.
A watermark may seem like a great idea for branding but it is an easy way to land yourself disapproval. All items on Shopping ads require an image with an unobstructed view of the product that does not contain additional promotional elements.
- Generic Images
Beware of the "generic images" disapproval! This happens when for some reason you don't have images for a product and you fill the image_link field with a default image, usually simply your company logo.
Pro Tip: You can now automatically improve uploaded images. Ensure they meet requirements, and improve overall user experience with automatic image improvements.
How to Optimize Google Shopping Product Images
High image quality is strongly correlated with user engagement and clicks. By improving your image essence, you'll provide a better experience for the users who view your item and you might increase the performance of your Shopping campaigns.
1. Use the Right Image
Make sure you’ve got the right images for the right product. This means setting up and parent/child attributes with all the right images too.
It seldom works to show a customer the wrong color, size, etc. Different product variations should have their proper pattern, size, and color annotated within your data feed, and the same goes for images.
The images you choose should help answer any questions a shopper has about the look and feel of the product.
2. Use High Resolution and The Appropriate Image Size
A poor quality image won’t do your product any justice and could steer shoppers away from buying your product.
Despite Google’s minimum size sitting at 100x100 pixels (250x250 for clothing & apparel) larger, high-quality images typically outperform smaller images.
CPC Strategy suggests using images 800x800 pixels or larger. These are more visually appealing and often depict exactly what the product is/does better than smaller images.
It’s a good idea to hire a professional photographer to snap perfect pictures especially if your own skills are scarce.
3. Focus on the Image Content
You must accurately represent the item you’re selling - this may seem obvious, but make sure that props or backgrounds aren’t overshadowing the item. It’s a must for your product to stand out.
The main image should be the photography of your product on a white background, so it won’t get lost in the shuffle.
Whilst you know your product very well, keep in mind that this could be the first time a potential customer has seen it. A shopper may not get a good feel for the actual product and move on to the next listing.
Note: Google recommends that the product should take up no less than 75% but no more than 90% of the full image.
4. Give your Images Some Retouch
If you are creating the images themselves, for a more professional image, try to get your images retouched.

5. Use Additional Images
Make use of the additional_image_link attribute and add up to 10 extra images to your listing. Usually, additional images show the product from a different angle or with product staging elements.
Give the shoppers the best possible idea of what they are buying and how can they use it.
6. Test lifestyle images vs. plain images
Any retailer wants the campaign to be bland and uninspiring. To avoid wasting your ad spending check if the dynamic, lifestyle images suit your product or service better.
There was a social experiment conducted around how people react to images with very interesting results. Participants were presented with shopping ads with both lifestyle images and plain images of a clothing item itself. Out of the random group of people tested, 82% answered that they would be more likely to click on a shopping ad first if the image was of someone wearing the product rather than of the product by itself.
So investigate which: product images or lifestyle images are more suitable and find which works best for your brand.

7. Regularly Conduct A/B Testing
The feed is not just a cold set of data. This concerns especially your product images. How else you could discover what is the most vital component of your ad if not by making A/B tests. Check images variations, analyze the results and apply adjustments to improve the performance of your ads. Take the guesswork out of the equation and find out what your customers respond to.
