Facebook disclosed on Wednesday that a comprehensive internal metrics audit found that discrepancies, or “bugs,” led to the undercounting or overcounting of four measurements, including the weekly and monthly reach of marketers’ posts, the number of full video views and time spent with publishers’ Instant Articles. None of the metrics in question impact Facebook’s billing, said Mark Rabkin, vice president of Facebook’s core ads team.
The unveiling of the additional errors may trouble some advertisers and web publishers that rely on Facebook for distribution and monetization. Several had already called for additional third-party validation of Facebook’s data.
