A pageview is a request for an item called a page in Web analytics. A page is loosely defined as all the requests required to build one Web page. A pageview can include many hits, as the page is built with CSS, scripts, and images.
Pageviews are a good unit of measure in Web analytics. The number of pageviews a website gets is a measure of how popular it is and how attractive it will be to advertisers. Most Web analytics tools will show you pageviews.
