Ask yourself what success looks like for your goals. If social is a focus than using Google’s social reporting can be helpful to see where you have the most influence and which channel is pushing people to your site. Are you tagging your links? Using a tagging schema allows you to see not only what channel is converting for you but what TYPE of links are converting the best. Are they videos? Links to your blog?

Actionable, profitable, and easy to see if you know what you are looking for heading into your search.
