Last week Twitter users Chris Ridley and Christopher Bell spotted a bug in the date comparison reporting tool in the Performance max Product Listing tab in Google Ads. The tool allows you to select “compare,” but doesn’t actually show you the information.

Google’s response. Google Liaison Ginny Marvin responded that she had flagged the issue to the ads team. 

Why we care. Accurate reporting is key to optimization. Advertisers need full transparency and the ability to view their data and compare performance across specific periods of time.
