Once you have created and saved your Ad group, the next step is to setup targets for your products. This is what Google AdWords will remind you about after the group has been saved, so make sure that when you proceed, the validation filter matches exactly the one you have used in your AdWords account for your best selling products.
Validate Ad Groups
Go to your Product Listing Ads, click on ‘+ Add Product Target’ as shown below
Note that every PLAs Groups needs to have their product targets clearly specified.
For your validation method, choose ‘AdWords labels’.

Therefore, before going for validation of your product target, make sure that your AdWords label should match exactly, just like in the example below:
Increase bids for individual Ad Groups
Just like the following example, bid higher for your Best Sellers Ad Group to ensure that they get more traffic – which means more visibility, and a higher chance of conversion.
