Your client wants to measure users' ability to see their video.Which metric within Campaign Manager 360 should they use to do this?

To measure a user's actual ability to see a video rather than just the technical event of the file loading, the Video views metric is the correct choice because it specifically tracks impressions that meet viewability standards. While "Video plays" only counts when a video starts regardless of whether it is visible on the screen, and "Video completions" or "Full-screen" track engagement and duration, "Video views" in Campaign Manager 360 is aligned with Active View technology to confirm the ad was actually in-view for the user. This distinction is critical for advertisers who prioritize "viewable" reach over simple delivery, as it filters out instances where a video might have played "below the fold" or in a background tab where it was never actually seen.
