Facebook defines EdgeRank as: Affinity x Weight x Time Decay. Facebook measures Affinity between Users and Pages by monitoring their interactions. Interactions are objects such as Likes, Comments, Clicks, Shares, Wall Posts, and anything else that Facebook can tangibly measure.
EdgeRank Checker provides complete analytics for Affinity. This is a valuable metric you will not find anywhere else!
The Affinity grade displays the process of understanding these Interactions. Facebook allows us access to analyze Interactions through Comments and Likes. Understanding how users are interacting with your Page can be incredibly powerful.
We are able to analyze these relationships in two valuable ways:
1. Identify how many Unique Engagers your Post received: This can be beneficial in understanding the difference between 25 people individually voicing their input, versus two people arguing their point a dozen times on your Post. Having 25 Unique Engagers is much more valuable to EdgeRank (as it builds Affinity with 25 users).
2. Relay if fans have commented on your Content within the past 30 days: This can be incredibly helpful as you begin to understand who you’re building Affinity with. Whether you want to reach new, or old fans (engaged in the past 30 days or not), you’ll be able to adjust your content strategy accordingly.
