How it works:
Google has introduced Channel Diagnostics within the Performance Max Insights & Reports section. The feature highlights issues that may be preventing ads from serving across Google channels (such as Search, YouTube, Display and Discover) and recommends fixes for missing or ineligible assets.
What’s the benefit:
Advertisers can more easily identify why campaigns aren’t reaching their full potential, helping improve channel coverage and maximise Performance Max reach without relying on manual troubleshooting.
