Quantcast this week launches a service which enables searching of websites according to key readership demographics.
The new facility enables marketers to enter a list of demographic parameters, and returns a list of websites whose readership matches those criteria. As an example, if a marketer is targeting black male readers, over 40, with an income over $60,000, then Quantcasts new service serves up a list of websites which attracts that audience, and also tells you whether or not the site accepts advertising.
Better yet, the service is free. Just sign up and target away.
