- Each time the user watches at least two seconds of the video
- Each time Active View recognizes TrueView
TrueView: Views: The number of times your ad has been viewed. For TrueView in-stream, this is the number of times a viewer watches for 30 seconds of your video (or the duration if it’s shorter than 30 seconds) or engages with your video (in-stream), whichever comes first. For TrueView video discovery, this is the number of times viewers choose to watch your ad by clicking a thumbnail.
