When implementing a social media plan, it’s important to evaluate your results and see what impact you have had. There are several tools available to measure social media outcomes. Some useful tools include:
Social Page Evaluator, which evaluates the value of Facebook Pages in terms of reaching audiences: http://evaluator.vitrue.com/
Twinfluence, which evaluates reach and influence of Twitter accounts:http://twinfluence.com/
Justcoz.org, which is an online relay system that lets you donate a tweet a day to help raise awareness for causes: http://justcoz.org/
These tools, courtesy of Chris Rottler at Knowledge for Health, and others like them will help you see the impact of your tweets, posts and more.
