Google has released a new metric column for Demand Gen campaigns called “% Served“. This addition helps advertisers compare ad delivery within an ad group, offering insights into which videos are prioritized by Google’s algorithms.

Previously, the lack of this metric often forced advertisers into a one-video-per-ad-group strategy to analyze performance effectively.
Now, “% Served” provides a soft understanding of ad performance, making campaign management smoother.
