Measures of (Social-Media) Success

Klout

Scoring across three networks

Klout offers a daily summary of your organization's or team members' social-media influence, with a ranking that factors in your reach and impact on Twitter (metrics such as retweets, follower counts, list memberships, unique mentions), Facebook and LinkedIn. Klout has an open API that's integrated into many Twitter apps: More than 750 partners use Klout data, including HootSuite, CoTweet and Attensity360. For the end user, its analytics platform is rich and easy to use, even if the methodology used in spitting out a Klout Score is a bit opaque.
