Hit
A single request from a
browser to a
server . Some servers also count each graphic on that page as a hit. For this reason, it's doubtfully to use the number of hits as an accurate measurement for the popularity of a
Web site .
In search terminology ,every listing a search engine returns from a search is called a hit.The term hit is also used to refer to calls on a web server,and it is much misunderstood.Technically,if a web page is called by a remote browser,and it includes three graphics,there are four hits on that server,one for the page,and one for each graphic.Many people and most âhit counters â use the term hit to mean hits on the web page only,not the calls to graphics or other supporting files that come with the page.When someone quotes figures on hits,be aware that definitions and uses vary,and try to find out what definition was used in producing the figures.
More than a
page view , a "hit" is
any action experienced at a web site. A "hit" is
any content delivered by a web server.  A single web page may place several dozen demands on the web server to deliver content: one for the page itself (or the collection of
pages that make up a frame set), another for each graphic image displayed, and others for streaming media, sound bites and other content.  Each of those demands is considered a "hit".  Every file a web server delivers is a "hit".  
Technically, a hit is a request made to a Web server. Though many people think the term refers to the number of visits a web page gets, that's not really the case. If a web page has 5 images on it, when the page is loaded, 6 "hits" will be recorded. One for the HTML of the web page and 5 for the images. Another way the term "hit" can be used is in reference to search engine results. When you search for a phrase and the search engine finds 2000 results, you can say there were 2000 hits and be happy because you used the term correctly.
