Facebook today is changing how it ranks the videos that appear in the News Feed, with the goal of better surfacing those that are more relevant to you. It’s a slight tweak, but one that could boost the visibility of longer videos, in some cases.
It can be more of commitment to watch a longer video in full, of course – the content has to be interesting enough to keep your attention. Now, long videos that people are actually watching may be distributed more on Facebook.
