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. `Average view rate = (Total video view time / Video starts) / Video length` Example Two users click to start a 20-second video and each watch exactly 10 seconds. The video view rate is calculated as 50% (20 seconds / 2 starts / 20 seconds).
Average view time Average time, in seconds, that a video is viewed per view.* `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 video 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. `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 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.
First quartile Number of times that a video plays to 25% of its length. This applies to in-stream videos only.
Midpoint Number of times that a video is played until the middle of its view length.
Skip 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. This applies to in-stream videos only.
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 percent of error per impression. This number can sometimes be greater than 100%. `Total error rate = 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 (at least) 100%.
Video length Duration of the video creative, if hosted by Ad Manager. This metric will only populate for reservations or Programmatic Guaranteed hosted by Ad Manager.
View-through rate Percentage of times the ad was viewed. `View-through rate = Engaged view / Skip shown` 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 as a result of things like 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. `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 66.67% (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.* `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). _{* 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.}
Full screen Number of times ad clip played in full screen mode. Event only applicable for Windows Media Player.
Mute 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.
Pause 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.
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.
