Facebook announced that they are now testing for the Related Articles feature in the Facebook News Feed. The feature launched in 2013 and would display related stories right below an article after reading it and returning to News Feed.
With this new test, Facebook is going to show related stories before you click to read an article. Based on trending stories, Facebook will show additional articles from publishers about the same topic, which gives readers the chance to read about alternative perspectives and third-party fact-checkers.
At this point, nothing else is expected to change, which includes Pages.
