A visitor is a unique individual coming to a website.
The best way to identify a visitor is with a cookie that identifies that unique system. But many Web analytics packages try to identify visitors through IP address and browser/OS information. It is possible to get decent information without a cookie, but cookies are more accurate.
The number of visitors to your website is an excellent metric regarding how popular your site is. The more visitors your site has, the more attractive your site will be to advertisers.
