Understand video ad report metrics
When you create a report for DFP Video, the following metrics are available, depending on the report type and video dimensions you've selected. Additional metrics exist for VAST errors and video content.
Video viewership metrics
Number of times that a video is started.
Number of times that a video plays to 25% of its length. This applies to in-stream videos only.
Number of times that a video is played until the middle of its view length.
Number of times that a video plays to 75% of its length. This applies to in-stream videos only.
Number of times that a video plays to its completion.
Average view rate
Percentage of a video that is watched by a user. For example, if a user watches 20 seconds of a 30-second video, the video view rate percentage is calculated as 66.66.
Average time, in seconds, that a video is viewed per view.
Total video view time / Video starts
For example, a 20-second video is viewed by one user for 20 seconds. A second user views the same video for only 10 seconds. The video view time is calculated as 15.00 seconds.
If a user drags the scrubber (video timeline) backward or stops the video altogether, the video view time is stopped.
Percentage of times the video played to the end.
Video completes / Video starts
Total error count
Number of times an error occurred, such as a VAST Redirect error, a video playback error, or an invalid response error, including for dynamic allocation (Ad Exchange and AdSense) impressions.
Total error rate
Total error count / (Total error count + Total impressions)
Duration of the video creative.
Number of times the "skip" button was shown (the skip button is shown 5 seconds after a skippable ad starts).
Number of times the ad was viewed to completion. For VAST 3 or 4, a completion occurs when the user reaches the "skippable video engaged view time" defined in your network settings. An engaged view is not recorded if the ad completes before it reaches the engaged view time set for the network.
Percentage of times the ad was viewed.
Engaged view / Skip shown
Number of times video ads play automatically. To implement auto-play metrics in your player, set the
autoPlayAdBreaksparameter using the SDK.
Number of times video ads have played when clicked. This is the default behavior of video ads.
Video interaction metrics
Number of times user paused an ad clip. Event logged once per view. If user repeatedly starts and pauses ad clip, it's not counted again.
Number of times the user unpaused the video.
Number of times a user rewinds the video.
Number of times video player was in Mute state during play of an ad clip. If player is muted before ad plays, it's counted the same as if user mutes player while ad plays. Event is logged once per view. If user mutes ad clip multiple times during play of ad, it isn't counted again.
Number of times a user unmutes the video.
Number of times a user collapses a video, either to its original size or to a different size. For overlays, this tracks the number of times the user minimizes the ad without fully removing it from the player.
Average time, in seconds, that an expanding ad is viewed in an expanded state.
Any expansion times that exceed several minutes are capped. Extended expansion time can occur when a user opens an expanding ad without collapsing the ad or closing the browser. This cap rule prevents skewed results for average display time in reporting. While this event is counted only once per impression, the time that the ad remains in an expanded state is recorded as the total expansion time.
For example, if a user expands an expanding ad for 10 seconds, and then the same user expands the ad a second time for 10 seconds, the number of expansions is recorded as one, and the total expansion time is recorded as 20 seconds.
Number of times ad clip played in full screen mode. Event only applicable for Windows Media Player.
Number of times an ad was skipped.
Average interaction rate
Number of user interactions with a video, on average, such as Pause, Full screen, Mute, etc.
Video interactions / Video starts
