Facebook continues to hone the algorithm controlling what posts appear in people’s news feeds, and while it’s regularly accused of being a “black box” (i.e. undecipherable to outsiders), the social network has made a point of explaining its actions when it makes changes. The latest example: a new crackdown on “stories that people frequently tell us are spammy and that they don’t want to see”. Specifically three categories: “Like-baiting” where posts explicitly ask users to like, comment or share a post in order to boost its reach; “Frequently circulated content” like photos and videos that are repeatedly uploaded to Facebook by page owners; and “Spammy links” that trick people to click through to websites stuffed with ads and digital junk. “The vast majority of publishers on Facebook are not posting feed spam so they should not be negatively impacted by these changes, and, if anything, may see a very small increase in News Feed distribution,” stressed Facebook in its blog post. That should include musicians, although it’s a warning to any music marketers who feel tempted to try any of the tactics above (Like-baiting being the obvious one) in order to make up for declining organic reach of their posts.
