EdgeRank

From Wikipedia, the free encyclopedia

 

 

EdgeRank is the name commonly given to the algorithm that Facebook uses to determine what articles should be displayed in a user’s News Feed.

An older definition of EdgeRank is as follows:

where:

 is user affinity

 is how the content is weighted

 is a time-based decay parameter

According to Techcrunch, some of the methods that Facebook uses to adjust the parameters are proprietary and not available to the public.^[1]

According to Marketing Land, Facebook stopped referring to its feed prioritisation algorithm as EdgeRank internally in 2010/2011,^[2] and so the term may be considered obsolete now – other than as a useful shorthand for “Facebook’s feed prioritisation algorithm”.
