System and method for estimating prevalence of digital content on the World-Wide-Web

Abstract

The present invention is a system, method, and computer program product for tracking and measuring digital content that is distributed on a computer network such as the Internet. The system collects online advertisement data, analyzes the data, and uses the data to calculate measurements of the prevalence of those advertisements. The system processes raw traffic data by cleansing and summarizing the traffic data prior to storing the processed data in a database. An advertisement sampling system uses site selection and definition criteria and a probe map to retrieve Web pages from the Internet, extract advertisements from those Web pages, classify each advertisement, and store the data in a database. A statistical summarization system accesses the processed raw traffic data and the advertisement data in the database to calculate advertising prevalence statistics including the advertising frequency, impressions, and spending.

1 . A system for estimating the prevalence of digital content on the World-Wide-Web, comprising: 
 an estimating device for estimating the global traffic to a plurality of Web sites to provide traffic data;    a sampling device for statistically sampling the contents of said plurality of Web sites to provide sampling data;    a storage device for storing said traffic data and said sampling data; and an accessing device for accessing said traffic data and said sampling data stored in said storage device.
