Video impression and viewability measurement methodology
Google uses an internal booking tool to plan and reserve YouTube campaigns on behalf of advertisers who opt for the direct reservation service.
Google’s proprietary Interactive Media Ads Software Development Kit (IMA SDK) is integrated directly into the YouTube video player, the YouTube mobile app, or video partner sites and apps to facilitate communication between the video players and the ad server for video measurement.. The IMA SDK is a Video Ad Serving Template (VAST) (versions 2.0, 3.0 or 4.0) with a compliant tag implementation used to measure both linear and non-linear video ad content to serve and track digital video ads. The IMA SDK also supports Video Player Ad-Serving Interface (VPAID) (version 2.0) that allows the video ad and video player to communicate with each other, as well as Video Multiple Ad Playlist (VMAP) that allows multiple ads to be played within the video ad content.
All measured YouTube video ads included in the video viewability report are delivered in-stream. For video ad impressions, measurement utilizes the count-on-begin-to-render methodology. The Google Ads IMA SDK solutions are consistent with the Video Impression Guidelines requirements regarding post-buffering initiation of the measurement event. YouTube Reserve Video viewability report uses a combination of user-agent and mobile app SDK data from internal and external sources to classify device types. YouTube Reserve Video viewability report does not rely on any third party to perform classification.
In some instances, continuous play is a factor, such as when Autoplay is active or the user is viewing a video in a playlist. When this is the case, certain rules are followed. When using Wi-Fi, continuous play will stop automatically after four hours. When using a mobile network, continuous play will stop if you have been inactive for 30 minutes. Please refer to https://support.google.com/youtube/answer/6327615 for the latest and most accurate details on this feature.
For video viewability, Google Ads utilizes the Active View description of methodology to measure viewability as reported within the YouTube Reserve reporting platform.YouTube Reserve Video Viewability report counts a viewable video impression when at least 50% of the video ad creative appears within the viewable area of a user’s browser/app for two continuous seconds.
- Third-party filtration is not used by Google.
- Sources used for identification of non-human activity: Google uses the IAB/ABCe International Spiders & Robots List as well additional filters based on past robotic activities. The IAB Robots List exclude file is used.
- Activity based filtration processes: Activity-based identification involves conducting certain types of pattern analyses, looking for activity behavior that is likely to identify non-human traffic. Google's Ad Traffic Quality team has systems in place to determine any suspicious activities and does such activity based filtering appropriately.
- All filtration is performed 'after-the-fact' and passively. That is, the user (browser, robot, etc.) is provided with their request without indication their traffic has been flagged, or will otherwise be filtered and removed as Google does not want to provide any indication to the user agent that their activity has triggered any of Google's filtering mechanisms.
- Processes have been implemented to remove self-announced pre-fetch activity.
- When inconsistencies or mistakes are detected, processes exist to correct this data and provide refunds to advertisers. These refunds are reflected in the billing summaries. The corruption of log files is extremely rare, but in cases where this may occur, processes exist to recover them.
- Processes have been implemented to remove activity from Google internal IP addresses.
- Filtration rules and thresholds are monitored continuously. They can be changed manually, and are updated automatically on a regular basis.

Video data reporting
For the purposes of MRC accreditation, only the metrics listed in the video viewability report are in scope. An immaterial amount of YouTube TV traffic may be present in the video viewability report for accredited Desktop and Mobile environments. Other reporting of video impression and viewability metrics across the other available YouTube Reservation reports are excluded from accreditation audit.
The metrics in the YouTube Reserve video viewability report are reported Total Net of SIVT across Desktop, Mobile Web, and Mobile In-App environments. Approximately 35% of total invalid video impressions traffic is estimated to be general invalid traffic.
- Skippable in-stream ads: In a skippable video ad, viewers are given the choice to skip the ad after the initial 5 seconds. After the view of a skippable ad, it will increment the YouTube view count at the 30 seconds mark or when the ad has been watched completely (creatives must be at least 12 seconds long to increment view counts). Skippable video ads can be a maximum of 6 minutes long.
- Bumper ads: Short video ads that are approximately 6 seconds in length that appear before, during, or after YouTube video content. Bumper ads are non-skippable ads.
- Non-skippable in-stream video ads: In a non-skippable video ad, viewers are not given the choice to skip the ad. Note that non-skippable video ads do not increment the view count. Non skippable ads can be a maximum of 15 seconds or 20 seconds, depending on the region where Ad is being shown.
