Yet another update to the News Feed that’ll change the prioritization of what you see at the top of your News Feed.
Interacting with a post (liking, commenting, or sharing) is a good indicator for what users are interested in; however, it is not the only way of gauging interest.
Users are less likely to interact with a sad news-related post or a serious current event, but that does not mean they do not want these stories in their News Feeds.
Facebook will now measure the potential interest in a post based on the following criteria: user interest in the creator, post performance among other users, past content performance of the creator, type of post the user prefers, and how recent the post is.
When you click on a post or link, Facebook will measure how much time you spend on post, even if you don’t like, comment, or share.
This will help Facebook in its algorithm when predicting and prioritizing which posts you are most interested in.
