Facebook in fresh video metrics row
Facebook was aware of inaccuracies in the way it measured how many people viewed video on its site for a year longer than it has previously admitted, court documents have claimed. In September 2016, Facebook admitted that it had overestimated how much video people had watched for the previous two years. The error affected a Facebook metric called "Average duration of video viewed", which was supposed to tell publishers for how long, on average, people had watched a video. Their case hinges on the fact that the numbers provided by Facebook meant advertisers put more money into its video ads than those on other platforms. Facebook now has a dedicated metrics team and allows third parties and experts to review its measurements regularly.
