In an effort to rid the News Feed of low-quality, spammy brand posts, Facebook announced on Thursday that it has made changes to weed out common techniques meant to dupe users into clicking and promoting content.
The most overt tactic that Facebook will work to curb is “like-baiting” — a common practice that encourages users to “respond” to messaging only in the form of liking, briefly commenting on or sharing a post. Facebook says its research shows that posts like these are 15 percent less effective than other page posts.
