EdgeRank is an algorithm developed by Facebook to govern what is displayed—and how high—on the News Feed.Just because someone has "friended" you, it does not follow that you will get to see their posts. Facebook has a complicated algorithim that decides what goes into your feed. You don't see all the material that has been posted by your friends and the pages you have "liked." Facebook, not you, decides what you really like.
So, if you want to build a page with a very high EdgeRank, you post manipulative posts asking readers to support a cure for cancer.
All about those Facebook "like" scam posts
Businesses worldwide are trying to figure out how to best utilise platforms like Facebook, Twitter and Google Plus (haha, na I’m just kidding about Google Plus). They know that EdgeRank, likes, brand exposure and followers are important, even if they don’t know exactly why or what to do with it.So a social media consultant manufactures a page with a high edgerank and sells it to some business who wants a page with high EdgeRank, but does not know how to build it. You know what would be cheaper and more effective than buying a pre-fab fan page from a social media consultant? Building a page on Facebook, putting interesting content on that page, and then buying advertising from Facebook to generate traffic, and ultimately EdgeRank. Sometimes paying the Facebook toll is the superior solution.
