Klout. Klout is a free service which will help you to analyse who is listening to your social media broadcasts and what type of social media person you are. When you look closely to the results and have a clear goal this can be a great tool help you with a social media strategy if you do not have a hughe budget.
Currently, they actively measure five networks: Twitter, Facebook, LinkedIn, Foursquare and Google+. These are just some of the actions Klout uses when determining your Klout Score:
Twitter: Retweets and Mentions
Facebook: Comments, Wall-Posts, Likes
Google+: Comments, Reshares, +1
LinkedIn: Comments, Likes
Foursquare: Tips – Todo’s and Tips – Done
You can also connect Facebook pages, YouTube, Instagram, Tumblr, Blogger, Wordpress.com, Last.fm and Flickr accounts. These networks do not yet impact your overall Score yet. Before a network can be fully integrated into the public score it must be rigorously analyzed, normalized, and tested by our science team. Once that is ready and tested, we release it and the new network will count towards your Score. The Klout Score is also measured on a 90 day time decay so by adding these networks to you are able to benefit from a longer window of data when the score goes live.
