Facebook will include time spent reading as a factor in news feed ranking

You might have heard: Facebook’s algorithm is largely a mystery to publishers, but the company has been using feedback from user surveys to select stories to show in the news feed

But did you know: Facebook is adding a new factor to its algorithm: It will now take into account how long users spend reading or watching a piece of content in their news feed. The length of the article will also be considered, so that longer articles will not necessarily be treated preferentially. Facebook also says it is making an update to increase diversity of sources in the news feed, which will reduce how often people see several posts in a row from the same source.
