What is “Unique Visitor”? A Simple Definition

Unique visitor is a web traffic measuring term which means the registering of at least one hit on one page of a web site from a unique IP address during a specified report period (typically anywhere from twenty-four hours to a month). A subsequent hit(s) by the same IP address is not counted as a unique visitor during that report period. Unique visitor count can be an effective way of measuring the success of an SEO strategy.
