The underlying insight behind the invention is that individuals and organizations responsible for the design, creation, and maintenance of their home page generally follow some basic unwritten rules. These rules can be exploited to automatically identify the owner of the home page with a high probability of success. Once the owner of the home page is determined, an SIC code is assigned to it by looking up the owner in a Yellow Pages database. If a matching entry exists, then the owner is a business, otherwise the owner is deemed to be an individual with a personal home page.
