There are so many ways to improve your shopping campaigns that sometimes it's difficult to prioritize the areas of improvement. And then when you start improving them you still have to wait and see the if results you get are the ones that you hoped for.
A sure way to improve the overall performance of the campaign is to find your bestselling products and focus on them. The thing is that managing individual bids for each product is just too much work.
Still, it's worth doing it because optimizing bids continuously for your most profitable products will really improve your ROI.
You want to identify a limited number of ‘Winners’, because you will need to spend time managing each bid. It is better to optimize a small number of products really well, than sub-optimize many products.
Don’t set a bid for each product with more than (e.g.) 5 conversions if that means you end up having 150 product groups. Instead, find out which products bring you the most revenue or gross margin.

Now you can see which of your products are the most profitable: Write 'em down or just download the entire report and go to the next step in Google Shopping.
The only way to set a separate bid for an individual product is to create a separate Product group for each product.
Creating those separate Product groups in the existing adgroup is possible but cumbersome: Having your ‘Winners’ in a separate ad group is easier to implement and provides for better focus.
So create a new adgroup and call it ‘Winners’ or something like that.
Go to the Product targets in this adgroup and divide the products by ID. Now you can simply paste the IDs of your Winners in a bulk upload:
Now that you have created Product groups for your winners, set a bid for each and start increasing your sales. Those bids must of course be higher than the bids in the original adgroup.
Or if you want to be really thorough, you should even exclude the winners from the original adgroup, to make sure that your new adgroup will ‘prevail’.
There is a lot of potential for increasing your ROI and your revenue with your best selling products, so they should get more attention compared to the rest of the products.
