Standardizing Reach Metrics with Total Co-view in the Google Ads API

Starting on June 2nd, 2026, the Google Ads API will transition reach metrics to a “Total Co-view” definition. This update aligns Google Ads reporting with offline media and third-party measurement standards, ensuring consistency across all reporting surfaces, including the Google Ads UI and Editor. The updated definition of the video view metrics will include all individuals who viewed the ad on connected TV devices, including cases where multiple people are watching YouTube together on the same TV screen.
