"The goal of News Feed is to show people the posts that are most relevant to them. “Why am I seeing this post?”, which can be found in the drop down menu in the right hand corner of a post, explains how your past interactions impact the ranking of posts in your News Feed. Specifically, you’ll be able to see:

• Why you’re seeing a certain post in your News Feed — for example, if the post is from a friend you made, a Group you joined, or a Page you followed.
• What information generally has the largest influence over the order of posts, including: (a) how often you interact with posts from people, Pages or Groups; (b) how often you interact with a specific type of post, for example, videos, photos or links; and (c) the popularity of the posts shared by the people, Pages and Groups you follow.
• Shortcuts to controls, such as See First, Unfollow, News Feed Preferences and Privacy Shortcuts, to help you personalize your News Feed."
