- 13. WHAT IS AFFINITY? Affinity is a one-way relationship between a User and an Edge. It could be understood as how close of a "relationship" a Brand and a Fan may have. Affinity is built by repeat interactions with a Brand's Edges.Actions such as Commenting, Liking, Sharing, Clicking, and even Messaging can influence a User's Affinity. http://www.whatisedgerank.com/
- 14. WHAT IS WEIGHT? Weight is a value system created by Facebook to increase/decrease the value of certain actions within Facebook. Commenting is more involved and therefore deemed more valuable than a Like. In the weighting system, Comments would have a higher value than a Like. In this system all Edges are assigned a value chosen by Facebook. As a general rule, it's best to assume Edges that take the most time to accomplish tend to weigh more. http://www.whatisedgerank.com/
- 15. WHAT IS TIME DECAY? Time Decay refers to how long the Edge has been alive; the older it is the less valuable it is. Time Decay is the easiest of the variables to understand. Mathematically it is understood as 1/(Time Since Action). As an Edge ages, it loses value. This helps keep the News Feed fresh with interesting new content, as opposed to lingering old content. http://www.whatisedgerank.com/
