Facebook News Feed Algorithm Change History

Every time you open Facebook, the news feed algorithm shows you a few posts out of an average of 1500 pieces of content from every page, group, friend, or event you’ve interacted with. There is simply too much content for each person to get through so the content you see is curated based on what Facebook thinks you will like most in an effort to keep you on the social network longer.
Each year, Facebook changes its news feed algorithm hundreds of times to include over 100K ranking factors and even more experiments every day to optimize this process. While most of these changes are minor, Facebook occasionally rolls out a “major” algorithmic update that affects the news feed and organic post reach in significant ways.
For social media marketers, knowing the dates of these official Facebook updates can help explain changes in organic reach and ultimately inform a winning social media content strategy. Here are the major algorithmic changes that have had the biggest impact on the Facebook news feed.

2017
December 18: Posts That Request Engagement Will Be Demoted
Including phrases like ‘like this’, ‘share this’, or ‘vote on’ in your post description to artificially gain reach will cause that post to be shown less in the news feed. Pages that engage in this behavior regularly will experience decreased reach overall.
December 14: Video Ranking Includes Repeat Views and Search Intent
Video distribution will be affected by how many users return to watch regular video content from that publisher, how many users navigate directly to that page, and how closely the content matches searches on Facebook.

October 5: Article Context
Facebook is testing a button to give users additional information about links before leaving the news feed. The new information comes from Facebook and other sources and includes the publisher’s Wikipedia entry, a button to follow their Page, trending/related articles, and information about how the article is being shared by people on Facebook.
August 28: Blocking Ads from Pages that Repeatedly Share False News
Until this point, Facebook blocked the ability for pages to run ads on false news stories. With this update, pages who frequently share false news will be blocked from creating ads altogether. This is designed to stop the economic incentives for Facebook pages to create and spread false news as a means of building their audience or making money from those links.
August 17: Taking Action Against Video Clickbait
In order to fight deceptive and spammy posts, videos of a static image or images with a video play button will be demoted in the news feed

Overly-promotional page posts that re-use the same content from ads, push people to buy a product or app, or promote contests/promotions without context will be demoted in the news feed.
