WHAT’S A FEW DECIMAL POINTS: Marketers and ad agencies are learning that their campaigns on Facebook may not have been nearly as effective as they thought. For two years, Facebook overestimated the average amount of time people spent watching video content on its platform. The social media giant disclosed in its online advertiser help center that the key metric was accidentally artificially inflated by only including videos viewed for more than three seconds. Facebook told ad buying agency Publicis Media that it likely overestimated average time spent watching videos by a whopping 60% to 80%, according to a letter Publicis sent to clients, which was reviewed by The Wall Street Journal. The miscalculation means marketers may have misjudged the performance of their video ads as well as decisions to move budgets into Facebook, while publishers who post videos on the platform are also affected. Facebook’s solution? A new name for a new metric for what was meant to be measured in the first place. Maybe it’s time for the internet’s so-called walled gardens to finally allow true third-party verification of their data.
