What are some of the uses of a Web bug on a Web page?
Web bugs can be used to provide an independent accounting of how many people have visited a particular Web site. Web bugs are also used to gather statistics about Web browser use at different sites on the Internet. In addition, advertising networks can use Web bugs to collect information on what sites a person is visiting to create a personal profile. The personal profile is stored in a database server belonging to the ad network and identified by the browser cookie of the network. The profile determines what banner ad one is shown at a later time. A more detailed outline of the uses of Web bugs appears under Advanced Topics.
