Twitter Grader Algorithm

Posted by Mike Volpe on 4/29/09 8:01 PM

I got a question on Twitter about how works.  I needed more than 140 characters. So here is a super quick and dirty blog post about how Twitter Grader computes the score.

Basically, Twitter Grader measures the authority of any user on Twitter.  This authority is computed by looking at the following factors from the entire database (over 2 million users today).

  1. Power of your network.  This means both the number of followers you have, as well as the power of your followers (the number of followers they have, etc.).
  2. Amount of interaction and influence.  How often do you tweet?  How many of your tweets are retweeted?  How often do people send @ replies to you?
  3. The basics.  Do you have a bio? Do you have a link in your profile?  Do you have a photo?  Do you update regularly?

The score is a 1-100 rank based on a percentile computation, so if you are in the top 1%, your scores is 99.
