The News Feed — in the center column of your home page — is a list of stories from the people and pages you follow on Facebook.
40% of users’ time on Facebook is spent on the News Feed. When a user logs in, there are normally many more posts than can fit in their “top news.”
EdgeRank is an algorithm developed by Facebook that governs what is displayed — and how high — on the News Feed. Knowing how Facebook decides what shows up (and what doesn’t) in news feeds is key for digital marketers. If you can write posts with an eye toward the EdgeRank algorithm, they will have a higher probability of being displayed in users’ News Feeds.
