Understand Video Solutions report metrics

Some metrics are only available for certain features, which might not be enabled for your network. You can see a list of feature availability, or contact your account manager for more information.

When you create a report for Video Solutions, 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.

Types of video metrics

	Indicates a quantity metric. These provide a total count of events.
	Indicates a calculated metric. These are calculated based on quantity metrics, by the formula shown.

Video viewership metrics

Metric	Metric type
Auto-plays Number of times video ads play automatically. To implement auto-play metrics in your player, set the autoPlayAdBreaks parameter using the SDK.
Average view rate Average percentage of a video that is watched by a user. Formula: (0.125 × videoStart + 0.25 × videoFirstQuartile + 0.25 × videoMidpoint + 0.25 × videoThirdQuartile + 0.125 × videoComplete) ∕ VideoStart Example Two users watch a video. One user watched the whole video, so there's one Video Start, one Video First Quartile, one Video Midpoint, one Video Third Quartile, and one Video Complete. Another user watched past the Video First Quartile but did not reach Video Midpoint. The average view rate is 0.6875 ((1 + 0.375) ∕ 2 starts).
Average view time Average time, in seconds, that a video is viewed per view.* Formula: Average view time = Total video view time ∕ Video starts Example A 20-second video is viewed by one user for 20 seconds. Another user views the same video for 10 seconds. The average view time is calculated as 15 seconds (30 seconds ∕ 2 starts). * If a user drags the scrubber (video timeline) backward or stops the video altogether, the video view time is stopped.
Click-to-plays Number of times video ads have played when clicked. This is the default behavior of video ads.
Complete Number of times that a video plays to its completion.
Completion rate Percentage of times the video played to the end. Formula: Completion rate = Video completes ∕ Video starts Example One user watches 20 seconds of a 20-second video creative. Another user only watches 10 seconds. The completion rate is calculated as 50% (1 complete ∕ 2 starts).
Engaged view Number of times the ad was viewed to completion. For VAST 3 or 4, a completion occurs either when the user reaches the end of the ad, or reaches the "Skippable view time" defined in your network settings, whichever comes first.
First quartile Number of times that a video plays to 25% of its length.
Midpoint Number of times that a video is played until the middle of its view length.
Skip button shown Number of times the "skip" button was shown (the skip button is shown 5 seconds after a skippable ad starts).
Start Number of times that a video is started.
Third quartile Number of times that a video plays to 75% of its length.
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 The average percentage of error per impression. Formula: Total error rate = Total error count ∕ (Total error count + Total impressions) Example A video creative duration is set improperly and the player reports this error for every impression. The total error rate is 100%.
Video length Duration of the video creative, if hosted by Ad Manager. Applicable to advertiser-hosted Programmatic Guaranteed or Preferred Deal programmatic video creatives only, this metric will report the "Max duration (seconds)" value set in the corresponding line item.
View-through rate Percentage of times the ad was viewed. Formula: View-through rate = Engaged view ∕ Number of times a user reached the "Skippable skip time" defined in your network settings Example One user watches 20 seconds of a 20-second video. Another watches only 10 seconds. The view-through rate is calculated as 50% (1 engaged view ∕ 2 skips shown).

Tracking for some video viewership metrics may vary slightly due to a number of reasons such as lost pings due to mobile network connectivity. For the most accurate data, ensure you're using the IMA SDK and have implemented player state functions, like onEnded(), correctly.

Video interaction metrics

These metrics are only available to publishers with access to advanced video features.

Metric	Metric type
Average interaction rate The average number of user interactions with a video. An interaction includes a click to collapse, expand, full screen, mute, pause, resume, rewind, skip, or unmute. Formula: Average interaction rate = Total video interactions ∕ Total video starts Example One user only interacts with a video creative to unmute (1 interaction). Another user unmutes and clicks to full screen (2 interactions). The average interaction rate is 150% (3 interactions ∕ 2 starts).
Collapse ​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.
Expand Average time, in seconds, that an expanding ad is viewed in an expanded state, per impression.* Formula: Expand = Total expansion time ∕ Total impressions Example One user expands an expanding ad for 10 seconds. Another user expands the ad again for 20 seconds. The expand is calculated as 15 seconds (30 seconds ∕ 2 impressions). * Expansion times that exceed several minutes are capped. An 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.
Full screen Number of times ad clip played in full screen mode. Event only applicable for Windows Media Player.
Mute Number of times the video player was in the mute state during the play of a video ad. If a player is muted before the ad plays, it's counted the same as when a user mutes the player while the ad plays.
Pause Number of times a user paused the video ad.
Resume Number of times the user unpaused the video.
Rewind Number of times a user rewinds the video.
Skips Number of times an ad was skipped.
Unmute Number of times a user unmutes the video.

Support for reporting issues is limited to video ads that use our IMA SDK.
