Facebook trained a machine learning model to spot engagement bait by feeding it hundreds of thousands of posts categorized as engagement bait or not. Now, its News Feed algorithm will demote posts that use engagement bait and over the next few weeks, it will also begin to more strictly demote Pages that repeatedly use engagement bait to artificially boost their reach.

Types of posts that won't be subject to demotion include posts that ask for advice or recommendations, circulations of missing child reports or money raising efforts.

This is the latest move Facebook has made in its battle against clickbait. It has already demoted posts with fake videos and tweaked its algorithm to bury fake news and clickbaity stories. Facebook says these efforts are meant to "foster more authentic engagement," which, according to its latest "Hard Questions" post, might influence how enjoyable or taxing social media can be.
