If you have Google Analytics setup, this is a good resource for quickly visualizing the effectiveness of your Social Media efforts.
Google Analytics has a section called Dashboards which allows you to customize a visual representation of how your site is performing on a single page. If you are just experimenting and would like a good Dashboard already made, Adam Singer created a social media dashboard that you can use for free.
Install this dashboard for free into your own Google Analytics by Clicking Here.
