The grey area in your Statistics page represents visits to your profile that weren't derived from a Slixa ad on one of our city pages. 

Most likely your profile views were generated from Google search. Since Slixa has excellent Google page authority and rankings, Slixa's profile pages often rank very high on entertainer name type-ins. Also, if your Slixa profile link has been posted on review sites, forums, boards, etc., that is another common way that people can find your Slixa profile without an ad.
