Amazon adopts MRC viewability standard for conversion attribution
Amazon announced this week that is now using the Media Rating Council’s (MRC) standard for viewability when reporting view-through conversions.
Why you should care
Under the MRC standard, an ad impression is considered viewable when at least 50 percent of the pixels are in-view for at least one second. Only impressions deemed viewable based on that standard are eligible for view-through conversion credits.
Until this update, advertisers have been able to opt to show ads only when an impression was viewable, but conversion attribution was not based on viewability. Instead view-through conversions were reported based on impressions served, with an attribution window of 14 days.
The change means that the view-through conversions Amazon now reports are based only on ad impressions that had a chance of being seen by the users that converted.
