Facebook News Feed Algorithm History

August 10th, 2018

Page Authorization Update

This update will require pages with a 'large' U.S. based audience to undergo additional verification which would confirm the country that person lives in and will require two-factor authentication. Facebook didn't define what they mean by a 'large' audience, but from the notifications we've seen essentially an active page with about 30,000 to 40,000 followers would qualify and based on recent news reports of pages with 20,000+ followers causing issues with political events we estimate Facebook could require pages with around 20,000 likes/followers to obtain the additional verification.

Facebook told us that the additional verification would need to be completed by August 28th, 2018.

This will impact the News Feed as pages that don't obtain the additional authorization will likely be unpublished or deleted, opening up coveted News Feed access to more authentic pages.

Assessing Credibility Update

This is a full implementation of a test Facebook started on October 5th, 2017 to see if providing additional information aided users in assessing the credibility of a news story that appeared in the News Feed. This test was one of several in response to the outcry that Facebook's technology was fostering and helping spread Fake News around the globe.

The update will now display other pieces of information along with an article from a publisher under an icon that reads "About this article". Once clicked the icon will reveal things like:

- A snippet from the Publisher's Wikipedia page & a link to the page
- A section of related articles from other publishers on the same topic
- A map showing where the article has been shared
- A section of recent articles from the publisher
- A section that shows all friends who have shared the same article

Local News Visibility Increased

Facebook increased the visibility of local news outlets in the News Feed in an apparent attempt to help fight fake news and to win pr points during the #DeleteFacebook movement and the Cambridge Analytica data leak scandal. The announcement was made on March 26th, 2018 but no definitive date was set on when this update would go live.

Explore Feed Test Ends

Facebook ended its 5 month long dual-feed test stating that users had said they were less satisfied. The Explore Feed test broke the News Feed into two components for selected users, a main feed and the 'explore feed'. The Explore Feed was largely comprised of content posted by fan pages (i.e. content from publishers). The stated purpose of the test was to show more content from friends and family, but with the Friends and Family update to the single version of the News Feed announced on January 11th, the Explore Feed was largely redundant.

Friends and Family Update

Facebook announced that the News Feed would prioritize updates from friends and family. They stated that the update would likely mean less engagement on the platform, but Mark Zuckerberg stated that he believes the engagement would be more valuable to users. This update is likely another response to allegations that Facebook's platform played a pivotal role in the 2016 USA Elections. The update was disastrous for publishers who had grown to rely on or were fully dependent on traffic from Facebook. One such publisher "LittleThings" shut down completely while others laid off staff members citing "industry changes over the past few months". Later one report would state that this update increased the cost of Facebook Ads 122%, the highest increase in ad costs on the platform the previous 2 years.

Updates to Privacy Controls Adjusted What Users Allowed to be Seen in the News Feed

Facebook began allowing users to control who would be able to see specific posts they made. The default categories were public, friends of friends, and friends. The update also allowed Facebook users to share content with a specific list of friends based on "friends lists" which was launched a few months earlier in December of 2007.

This update adjusted content seen in the News Feed by users indirectly as content that may have been shown to a user would be restricted based on the settings of each post.

Facebook Launches News Feed

Facebook launched News Feed and Mini Feed (i.e. the Wall). At the time the social media website had 9.5 million users, according to TechCrunch. The update was incredibly unpopular among Facebook users and prompted an open letter from Mark Zuckerberg himself to the community. Up until this point in time users had to visit their friends pages one by one to see updates.

The Facebook News Feed has been the core of the social media giants products for over a decade. The feature has been mired in privacy concerns since the day it launched and has gone through dozens of changes moving from a chronological order to being controlled by an algorithm that decides what content users see. The feature was introduced when the site had less than 10 million users and is largely credited with helping the site grow to over 2 billion users. We’ve tracked down every single change to the News Feed algorithm that has been published to help users, marketers, and technologists see a just how the News Feed has changed over time. Unlike the News Feed our timeline is in chronological order starting with the most recent changes and ending with the launch of the feature.
