AÂ General Overview of EdgeRank
An âEdgeâ is defined as any activity that occurs on Facebook that can potentially create a newsfeed story. This includes Likes, Comments, tags, RSVPs, or any public activity that a user undertakes. Facebook utilizes the EdgeRank algorithm to filter newsfeeds and show posts most relevant to the user.EdgeRank Factors
While EdgeRank has its own unique formula, when applied to Facebook, it becomes simple. The algorithm bases it results on three logical components: Affinity, Weight, and Decay.
Edge Affinity â" It´s all about Connections
The Affinity score is measured by the relationship you have with the user that created the âedge.â The more interconnected you are, the higher the Affinity score. If you have a large number of Friends that Like a similar Page, it is more likely that this content will arise in your newsfeed.Edge Weight â" Are Photos too Heavy for Newsfeeds?
There are two Weight types: post and interactions. EdgeRank takes the Weight of posts into account by determining whether the post is a photo, video, link, or text only status update. Regarding the Weight of interactions, Shares and Comments require more from a user than a simple âLikeâ, and therefore they are more heavily weighted and reach more users. See how the reach of different post types has decreased in September 2012 and discover which one has surprisingly reached the most users in newsfeeds here.Time Decay â" Engagement Occurs Within Minutes
An old story is a dead story. Facebook does not chronologically order âedgesâ, however, it does factor in Time to the algorithm. When we collect engagement data in Analytics PRO, we see that the vast majority of engagement occurs within minutes after a post is published (see graph below).
EdgeRank Means Reach
Since EdgeRank is used to determine how many people the content will be displayed to, we can quantify these results as âReach.â Socialbakers can provide an insightful estimation of the Reach of all brands by measuring aggregated engagement data. We have already established that there is a Return on Engagement (ROE) in social media as engagement directly correlates with Reach.
When your engagement reaches a certain level, a direct correlation between the total number of interactions and the number of Shares appears. The reach is approximately 100Â times larger than the number of interactions a post receives. Therefore if a post generates 100Â interactions, it is roughly reaching 10,000Â people.
