If you're losing way more than you're earning, you could have incorrectly allocated your PPC spend across variation listings.

In this video tutorial, I show you how Scale insights can help you determine where to spend when bidding for each variation.

I guide you through a graph showing data of an actual product listing.

The key is not to spend equally across every variation listing. Instead, focus the spend on your two or three best-selling products and use them as a funnel.

You can only find the best strategy for variation listing through trial and error, so don't be afraid to take risks and constantly test your methods.
