How Klout measures individuals’ social reach

Klout.com is an online (and free) web tool that helps you rank people who talk about your products or services in social media. Recently, their "Klout Score" metric started including Facebook in the
score analysis. This is what that looks like for my personal accounts in terms of "true reach" (= size of my engaged audience) and the amplification potential of my messages (= likelihood that my content will be acted upon) .

Klout does not just measure influence by counting the number of friends or followers on Facebook or Twitter, but by the ability to drive action. Examples:

• Reach: followers, friends, mention %, and retweet %
• Amplication: retweets, mention count, unique messages retweeted, in/outbound message ration, Facebook likes, and Facebook comments

Someone's true network, in other words, is not made up by the sheer volume of friends or followers, but by retweeters, likers and commenters.
