Google Analytics has sent an email to PostRank users which suggests that they have been able to integrate the social reporting with Google analytics which will give you an idea that how these channels are helping you to get traffic. The email is as appended below:
Since last July when PostRank joined the Google family, our combined teams have been hard at work integrating Social reporting within Google Analytics.
The new Google Analytics Social reports will help you identify the full value of socially referred traffic and see how the social channel contributes to your goals, conversions, and ecommerce transactions. Additionally, the new reports will also help you measure your visitors on-site engagement, where they came from, and even help you identify off-site conversations about your content.
What PostRank users need to know:
A new set of Social reports being released in Google Analytics which will provide useful data to show the value of social for your business or website in an innovative way.
