EdgeRank is SEO for Facebook. Social media is playing an ever increasing role in attracting customers and traffic.

The maths or formula behind Facebook’s secret sauce isn’t hard understand, think of it this way. Every thing that is displayed in a user’s news feed is called an object, and when you see an object in the news feed for example an status update and you interact with that object that’s what Facebook calls an Edge so status update = object and a action such as a like or comment on this object = Edge

Every Edge that is created has 3 components that are important to the algorithm

Number 1 – Affinity Score

If you send your friend a lot of Facebook messages and check out their profile often (yeah we’re talking to you Facebook stalkers!), then you will have a higher affinity score for that user than you would for someone you don’t engage with.

Number 2 – Weight

The weight of each edge differs for example a comment will have a bigger weight in the EdgeRank algorithm than a like. And a like is worth more than an impression and so on.

Number 3 – Age

This one is quite simple, the older an Edge, the less important it becomes.

It’s only when you multiply the 3 factors above and add the edge scores up do you get an objects EdgeRank, and of course the higher the edge rank score is the higher the chances are of the object appearing in a users news feed.

Simple.
