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-play 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 Percentage of a video that is watched by a user.
For 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 didn't reach Video Midpoint. The average view rate is 0.6875 ((1 + 0.375) ∕ 2 starts) . Formula: (0.125 × videoStart + 0.25 × videoFirstQuartile + 0.25 × videoMidpoint + 0.25 × videoThirdQuartile + 0.125 × videoComplete) ∕ VideoStart |
|
| Average view time Average time, in seconds, that a video is viewed per view.
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 average 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. Formula: Average view time = Total video view time ∕ Video starts |
|
| Click-to-plays Number of times video ads have played when clicked. This is the default behavior of video ads. |
|
| Completes Number of times that a video plays to its completion.
|
|
| Completion rate Percentage of times the video played to the end.
For 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). Formula: Completion rate = Video completes ∕ Video starts |
|
| Engaged views 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 quartiles Number of times that a video plays to 25% of its length. |
|
| Midpoints Number of times that a video is played until the middle of its view length. |
|
| Skip buttons shown Number of times the "skip" button was shown. The skip button is shown 5 seconds after a skippable ad starts. |
|
| Starts Number of times that a video is started. |
|
| Third quartiles Number of times that a video plays to 75% of its length. |
|
| Total error count Number of times an error occurred. Examples include 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.
For example: A video creative duration is set improperly and the player reports this error for every impression. The total error rate is 100%. Formula: Total error rate = Total error count ∕ (Total error count + Total impressions) |
|
| 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. |
|
| Video view-through rate Percentage of times the ad was viewed.
For 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) . Formula: Engaged view ∕ Skip 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. For 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) . Formula: Video interactions ∕ Video starts |
|
| Collapses 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. |
|
| Expands 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 one user expands an expanding ad for 10 seconds. Then another user expands the ad again for 20 seconds. The expand is calculated as 15 seconds (30 seconds ∕ 2 impressions) . Note: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. Formula: Expand = Total expansion time ∕ Total impressions |
|
| Full screens Number of times ad clip played in full screen mode. Event only applicable for Windows Media Player. |
|
| Mutes
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. Note: The "Mute" count may be higher than "Start" count for video. For example, this can happen when first mute is triggered by the SDK via |
|
| Pauses Number of times a user paused the video ad. |
|
| Resumes Number of times the user unpaused the video. |
|
| Rewinds Number of times a user rewinds the video. |
|
| Skips Number of times an ad was skipped. |
|
| Unmutes Number of times a user unmutes the video. |
Support for reporting issues is limited to video ads that use our IMA SDK .
