Media Rating Council Issues Industry Update On Mobile Viewable Impression Measurement

Key areas updated include:

• Deepened cross-industry collaboration: The MRC has collaborated with a large working group of interested parties and organizations to obtain data in order to answer questions surrounding viewability requirements applied to mobile environments.
• Eliminated the "Loaded Ad" concept: The MRC has concluded that the "Loaded Ad" metric is no longer necessary for use as a measurement metric. Introduced within the Interim Guidance in May, this metric was designed as a temporary solution that recognized limitations in measurers' capabilities for determining viewable impressions in mobile application environments that existed at that time. Since May, it has become apparent that measurers can now, in fact, successfully measure viewable impressions in mobile within the in-application environment, meaning the "Loaded Ad" concept is now obsolete. No vendors to-date have been accredited by the MRC for a "Loaded Ad" metric, and, effective today, the MRC will no longer consider accreditation of this metric.
• Found additional evidence that "Count on Decision" approaches for served ad impression measurement (in which the count of an ad impression is executed at a relatively early stage of the ad delivery process) should be eliminated as a valid method for counting served impressions: MRC's review of mobile data has shown that mobile ads can take a considerable amount of time to render on users' devices. This reinforces earlier findings from MRC's work on viewability in desktop environments that showed ads take longer to render in today's more complex online environments than they did when the IAB Measurement Guidelines for served impressions – which allowed for Count on Decision-based counting methods – were written a decade ago. Therefore, as previously announced, the MRC will work with the IAB to eliminate Count on Decision as an acceptable method for counting served ad impressions in the near-term future.

The MRC continues to evaluate data to further develop mobile viewability standards and will present preliminary conclusions based on information reviewed to-date later this month to the Mobile Viewability Working Group that was formed for this project. A final mobile viewability guidelines document is expected to be released for public circulation and comment period in Q1 2016.

The Interim Guidance issued in May remains in effect, and follows similar criteria as currently required by the MRC's Viewable Impression Measurement Guidelines to determine viewability in desktop environments. Viewable impression measurement of ads in both mobile web browser and mobile in application environments should follow the existing guidance for viewability in desktop (50 percent of pixels in the viewable space of the browser for a minimum of one second for display and two seconds for video ads).
