You sit down at your desk or kitchen table, open a new browser and sign into Facebook. Starting from the top of the page, you scroll down, scanning through items in your Facebook stream as you go. Some status updates catch your eye, as may a new photo album or quiz. But with a few hundred or so Facebook friends, there’s no way you’ll ever have time to go through everyone’s posts in your Facebook stream, right?
Well, you don’t have to.
This algorithm, called EdgeRank, applies to your Top News feed only. Those of you who view your stream with the Most Recent filter will see exactly that – the most recent updates. However, Top News is the default unless changed by the user.
EdgeRank rates all status updates, links, photos, videos, comments, likes and polls, and the resulting score determines whether or not an update, link, photo, video, comment, like or poll will be added to your Top News stream.
3 Components of EdgeRank
Facebook’s algorithm is comprised of 3 factors: Affinity, Weight and Time Decay.
– This relates to how much you interact with your other friends. Quite simply put, you’re much more likely to see posts from your best friend, whose wall you visit and whom you regularly interact with, than some former high school classmate who friended you and you haven’t connected with since.
– Each type of posting bears a different weight. Photos and videos are high on the importance chart, whereas Likes are near the bottom. A status update that receives multiple comments can increase in “weight”, too, due to the interaction by your friends.
– The older something is, the less likely it is to appear in the Top News stream.
Check the EdgeRank of your Facebook Fan Page
Now that you know what EdgeRank is and the basics of the components that comprise the algorithm, you may be curious to know your own EdgeRank score. EdgeRank Checker offers a free (as well as paid version) tool that estimates your score on a scale from 1 to 20+ (anything 20 or higher is considered “Excellent”).
EdgeRank Checker provides you a score by week, month or year, and – if you choose the paid option – provides more in-depth analytics (beyond what is shown below) like the number, type and time of day for your posts.
