By now we're all aware that Facebook shows our page's content to only a small number of fans. Some of us are even aware of Edgerank - the formula FB uses to decide which content is popular.
Here's a great article explaining this in detail.
A MUST READ for anyone marketing on Facebook:
http://techcrunch.com/2014/04/03/the-filtered-feed-problem/" Every Page on Facebook wants everything they post shown to everyone. But people only read a limited amount of News Feed per day. There simply isn’t room for everything, and the competition for feed space is intensifying. The total number of Pages Liked by the typical Facebook user grew more than 50% last year ....
...all Pages and people are not treated equally because Facebook’s goal is to show people the most engaging posts out of all the ones they could see each day...
It built a News Feed sorting algorithm, unofficially known as EdgeRank, that analyzes every signal possible to determine the relevance of each post to each person. This takes into account:
- How popular (Liked, commented on, shared, clicked) are the post creator’s past posts with everyone
- How popular is this post with everyone who has already seen it
- How popular have the post creator’s past posts been with the viewer
- Does the type of post (status update, photo, video, link) match what types have been popular with the viewer in the past
- How recently was the post published"
