I'm dealing with a Shopify store that has thousands of products. Unfortunately there's not a lot organizing in terms of product types and there's a ton of small accessory items that go in larger 'kits' that we don't really want to feature. I'd love to get the top sellers into a google shopping campaign but don't know where to start. Could I create a 'Best Selllers' collection and then have Shopify pull from that? Or is there a better way to go about this?

I'm a Creative Director trying to wrap my head around the Google ads side of things for a few of my clients. Hoping to get my ad accounts cleaned up and organized and better understand the specifics of what to look for to improve results. Looking forward to learning from you all.
