each time a web server sends a file to a browser, it is recorded in the server log file as a "hit". hits are generated for every element of a requested page (including graphics, text and interactive items). if a page containing two graphics is viewed by a user, three hits will be recorded - one for the page itself and one for each graphic. webmasters use hits to measure their server's work load. because page designs vary greatly, hits are a poor guide for traffic measurement.
