From the website:

"Our philosophy is not to concentrate on the larger Web sites that other site representation companies seek. We believe that small- and mid-sized niche Web sites provide our advertisers and publishers with a more focused and selective reach. Likewise, we have found that the users of these niche Web sites are extremely active and more comfortable with their online experience.

With RealCast Media highly selective targeting capabilities, clients can track their online marketing strategies by a number of variables. These variable include country, state, city area (designated market area), day, hour, browser type, operating system, domain name, IP address and language."
