Active View
The average time, in seconds, the ad appeared on screen. Only viewable impressions are counted toward this metric.
Average Viewable Time is capped (stops recording) as follows:
- Display ads: at three minutes
- Video ads: at the end of the video, or if the video is longer than 20 minutes, at five minutes per quartile
If the user scrolls away from the ad so that it is no longer considered viewable, the time on screen counter stops. If the user scrolls back to the ad so that it is considered viewable again, the counter resumes.
If the user switches to a different browser tab, time on screen stops recording. For video ads, the ad must be playing in addition to all of the above for time to be counted.
Example: A video ad that played for 10 seconds, was navigated away from, then returned to and played for another 10 seconds gives an average viewable time of 20 seconds.
Note: This metric is not available in Display & Video 360 for YouTube.
