What is the difference between hits and unique visitors?
A “hit” is generate by EVERY call to the web server, including the page and calls to get images, style sheets, and other content linked to the page. For example, a page that has 5 images will generate at least 6 “hits” for every on visitor who goes to it : one hit for the html file, plus 5 additional hits, one for each image. You can see why relying on HITS as a basis of measure for web site traffic is misleading. Unique visitors (typically a much lower number than “hits”) is a better measure of traffic to your site.
