Facebook’s EdgeRank Formula
Σ ue we de
- ue – affinity score between viewing user and edge creator
- we – weight for this edge type (create, comment, like, tag, etc)
- de – time decay factor based on how long ago the edge was created
As the formula notes, Sigma, or EdgeRank, is composed of three primary components:
What’s an “Edge”?
In order to provide a balanced equation, Facebook views all input as “objects.” Meaning, Status Updates, Pictures, Videos, Links, etc., these are all objects for Facebook to consider. For the purpose of defining what can be edged, these objects are all the same. Now that’s not to say that some objects won’t have a higher likelihood of becoming edged, but more on that in a minute.
The more often you like, view, comment, click on a friend’s object, the higher your Affinity score towards this person rises. Likewise for brands, the more often you check in with Red Bull, either via commenting, liking a photo or two, etc., the more Red Bull-centric your News Feed will become.
It should be noted that according to The Daily Beast’s research, Affinity score is a one-way street only. Affinity is from one user towards another, and not vice versa. Meaning, even an army of Acme Toilet Cleaner Facebook marketers can not command more attention on the platform simply by clicking incessantly on fans’ items in order to gain more exposure.
When it comes to edges, Facebook places a great deal of importance on weight: The longer an end user engages or interacts with content, the better it is for Facebook. Thus, Facebook applies a Weight to each object to help determine the object’s overall EdgeRank.
While no clear-cut scientific data can support this claim, it would appear as though the hierarchy of Facebook EdgeRank importance is as follows:
- Status updates
But it’s not just the posted content that factors into EdgeRank. Remember the Affinity score above? How many photos did you “Like” today? And how many images did you leave a comment on? And there we have it – the comments. Comments are the single most valuable factor in an object’s EdgeRank. The Facebook reasoning here is user engagement. Meaning, it takes much more effort on the end users’ part to type out a comment than to click a “Like” button.
In order to remain up-to-the-minute relevant, Facebook employs a “freshness” factor to all edged objects. It’s this “freshness” factor that helps determine what and when you see it.
For example, major world news events always bring a massive spike of activity to Facebook, readjusting a wide variety of Affinity and Weight scores and receiving a large number of comments, likes, interaction, et cetera. But that doesn’t mean that this news should still remain at the top of your News feed weeks later. Again, Facebook’s Time factor ensures that Top News really is Top, and not “last weeks.”
