Whats the difference between a Hit, a Pageview, and a Visitor?
A hit is merely a request to the server for a file. This means that one HTML page can, if it has several images, account for many hits. “Hits” represent an actual, hard number. A Pageview is defined as a request for a display-able page, such as “index.html” or “products.htm”. An image is not a Pageview. “Pageviews” represent an actual, hard number. A Visitor is defined as a series of hits from any particular IP address. If any two hits are separated by 30 minutes or more, two visitors are counted. “Visitors” represent an extrapolated number.
