We’ve recently completed a redesign of the profile page to allow us to incorporate a new feature – Common Audience. The common audience list displays a range of other sites that visitors to the profiled site frequent. The higher the score, the higher the affinity for the the listed site.
Common audience is not the same as simply listing the referrers, rather we consider the full range of sites that the visitors to a given site also visit. The results can help you understand characteristics of a site’s audience as well as suggest other sites that might have content or audiences that would interest you.
