Each time a user visits a Web page, it is called a page view. Page views, also written "pageviews," are tracked by website monitoring applications to record a website's traffic. The more page views a website has, the more traffic it is receiving. However, since a page view is recorded each time a Web page is loaded, a single user can rack up many page views on one website. Therefore, unique page views are commonly tracked to log the number of different visitors a website receives in a given time period.
Page views are more similar to impressions, which are commonly tracked by online advertisers. Page views and impressions may be identical if one advertisement is placed on each page. However, if multiple ads are positioned on each page, the number of ad impressions will be greater than the number of page views.
