Data Hub Metrics and Google
Using Data Hub Metrics to further your marketing campaigns.
There is mounting evidence that user metrics and social signals are playing an ever increasing role in how Google determines website quality. While I do not believe Google Analytic data is used directly to rank web content, I do think it is a great insight into what Google is "learning" about your site via user experience.
The social data hub is a free platform that social networks and other social platforms can use to integrate their activity streams- like +1, votes, and comments-with Google Analytics.
