2017 In Review:
In January 2017, Facebook has refined its algorithm. Last time, we went through two changes of its algorithm. Today, we continue to review the rest of the refinement.
Facebook has decided to optimize the user experience by incorporating a new metric to evaluate videos’ prominence so as to prioritize them in the News Feed. This new metric, known as “percentage completion”, is adopted to measure the users’ engagement. If a video is watched halfway, its content is considered to be “compelling”. On the contrary, if the “percentage completion” of a video falls below 50%, it is an indication of inadequate commitment.
In other words, after this Facebook algorithm revision, long videos may not be necessarily inferior, while short videos may not always be superior.
