It’s no secret that Performance Max campaigns present limitations in terms of data and insights we can pull from them. As a result, understanding the causes of their performance fluctuations can be difficult.

I’ve created an in-depth 44-point checklist for ecommerce businesses in this article to make accomplishing that task easier for you.

Of course, you don’t need to go through every single one of these points. Just go over the ones that are relevant to your business.

I also discussed some of these points on PPC Town Hall with Frederick Vallaeys and Mike Rhodes. You can watch the full video here:
