Hits are often unreliable in judging traffic for a site, since a hit is simply how many times the server sends information to a visitor. Information sent to visitors can be text, images, or any other file, so if a person looks at a Web page with 10 pictures on it, the hit-measurement could be 11 hits  from one page.

Page views are a much more reliable rate of measurement for traffic. A page view means if one page is sent from a Web site to a visitor the measurement would be one page view. If someone looks at five pages  (htm, html, asp, php) on a site the measurement would be five page views.

Unique visitors is the most valuable way to tell how well a Web site  is doing in terms of visitors.  It is how many people visited a site in a given time period. It doesn't matter if someone looks at one, or one hundred pages, the count would be one unique visitor for that person's visit.
