EdgeRank

The algorithm Facebook uses to rank business / brand pages, groups, celebrity pages or individual accounts to determine which posts from those accounts will appear in the Newsfeed of users connected to those pages and profiles (or pages and profiles tagged in the posts). The higher the EdgeRank, the more likely your posts will appear in the Newsfeeds of your followers. Originally this algorithm was primarily influenced by the level of engagement accounts receive from their posts, but has since been updated to take more factors into consideration. Facebook does not release this data publicly, nor does it use the term internally. This is a huge factor to consider in social media marketing,
