The Google Analytics team has just announced a new initiative to improve its social reporting capabilities: Social Data Hub. It’s not (yet) a set of reports but rather a way for Google Analytics to centralize social activity from a variety of social networks. With Social Data Hub, Google is opening its interface to enable social media platforms to make their impact visible to marketers, publishers and analysts using Google Analytics. This means that marketers will now have access to social interaction happening in and outside their websites.
