Who is your most valuable, most engaged and best Twitter follower?  Alex Taub and Michael Schonfeld can tell you.  The pair first developed a method to determine someone’s most valuable Twitter followers, which quickly gained popularity, before shutting it down to take jobs at Dwolla, a payments platform.

SocialRank Twitter

After launching service, founders took day job before returning

Taub and Schoenfeld initially launched a site called Most Valued Follower (MVF), that offered brands a service that helped them identify their most influential, and significant, followers.  The service quickly built a following of 50,000 users before the founders took a job at Dwolla.  The two recently left Dwolla and established SocialRank, picking up the pieces of Most Valued Follower.

Knowing three types of Twitter follower: most valuable, most engaged, and their best follower

SocialRank helps marketers identify three types of follower: most valuable, most engaged, and their best follower. In order to determine the most valuable follower status, the site uses an algorithm that considers, among other items, the total follower count, follower/following ratio, and if someone is verified.  The Most Engaged Follower interacts the most based on retweets, mentions, favorites and the total number of that person’s followers doesn’t impact the formula.  The formula combines the moves valuable follower and most engaged follower to determine your best follower in the past 30 days, the one that “strikes a great balance of engaging with you and has the reach or importance,” the site said.

Not like Klout, service plans to expand offering to include Vine, YouTube, Linkedin, Pinterest and Facebook

While the service might sound like Klout, which measures a Twitter user’s influence, there are key differences.  SocialRank doesn’t assign the Twitter user a value, as Klout does, but rather identifies only the top Twitter followers.  Currently it looks at Twitter, but plans exist to expand the service to Vine, YouTube, Linkedin, Pinterest and Facebook.  SocialRank is also building features to allow Twitter users to “reward” their most valuable, engaged, and best followers as a sign of appreciation.

Free for non-profits, or $25 per month

SocialRank is free for nonprofits to use, but costs $25 per month or $250 annually to be able to export daily and weekly reports, according to a report.  With the paid option, brands can break down their followers by demographic, geographic, and all the social media accounts that are attached to the individual.
