This infographic explains the best strategies for better social media results. Created by the Awareness Network (Thanks to Marshall Sponder for sharing in Pinterest), the graphic notes the currently analytic tools available. But again keep in mind most tools still can be siloed - a tool for Pinterest is telling about activity, but not enough by its self to indicate value to a business. It is up to the marketing team to establish what activity is sought on a social media channel. Infographics like this one help clarify what is possible.
