I've only been running one website for a few months so I'm a bit new to this. Could anyone explain exactly what is meant by a "hit"? In my web statistics there seem to be variations. For example on some occasions a visitor recording one page can score only one hit. At other times one page can result in about 20 hits. The other thing is that I am not always sure that what appears as the number of pages scored by a visitor is literally true because I've tested it by visiting my own website.
