Facebook announced the change to its algorithm on Tuesday in a post aimed mainly at owners of “Pages,” which are generally created for companies and public figures rather than individuals.
The company explained that it had previously begun showing more text-only posts in users’ newsfeeds, because internal tests showed that it caused people to write more status updates themselves. In fact, when Facebook began showing more text posts at that time, users posted an average of nine million more status updates each day.
But over time, Facebook realized that text updates from Pages didn’t have the same effect. So, Tuesday’s newsfeed change treats text posts from Pages “as a different category from those of friends.”
