Content Meter is a library that allows users send statistic information about advertising campaigns in a websites.
It is unprecedented in its class as, unlike common widely used meters (for example AdRiver, Google Analytics) providing only standard data on the number of impressions and clicks through, Content Meter makes it possible to determine better-quality data: the number of contacts that an Internet-user has with content, users’ interests (other websites that the user visits), and most importantly, to get social and demographic characteristics of the audience.
