A new Website, Quantcast - Open Internet Ratings Service, provides internet audience information, audience data charts, graphs and its interpretation. A good analyzing tool for Advertisers indeed, runs by a team of web analytics experts.

As apparent in Quantcast Website, it provides "free", accurate audience report by becoming (Registering) Quantified Publisher.

Quantcast is a Web site that is based on presenting the statistics of other Web sites. The prime focus of Quantcast is to scrutinize the Internet's Web sites in order to obtain accurate usage statistics by surfers from the USA. Like Alexa. Quantcast rates Web pages by ranks. Alexa data and Quantcast data does not always show the same results because Quantacast always refer to the usage from the United States. Quantcast does not need a tool bar to be installed upon one's web browser to get statistics.

The code allows Quantcast to keep track of the traffic directed towards those Web sites. By means of this mechanism Quantcast can offer thorough details about Web pages created by participating publishers. This information is presented by conjecture: comparing and correlating the information received from one participating publisher with another. The inferences are probable because the Quantcast code causes the user's browser to access Quantcast's servers, at which time they can log the user's IP address and information Quantcast places in cookies that are stored in the user's browser. The cookies appreciably aid in making inferences.
