Content Group
A defined group of web pages with specific things in common, such as the same types of services, or information.
Visits
Number of visits where the visitor viewed at least one page in the specified content group. A visit is a series of actions that begins when a visitor views their first page from the server, and ends when the visitor leaves the site or remains idle beyond the idle-time limit. The default idle-time limit is thirty minutes. This time limit can be changed by the system administrator.
Hits
Each file requested by a visitor registers as a hit. There can be several hits on each page. While the volume of hits reflects the amount of server traffic, it is not an accurate reflection of the number of pages viewed.
Unique Views
Same as visits but visits from the same user (the same IP address) will only be counted once.
Pageviews
A page view is each time a visitor views a webpage, irrespective of how many hits are generated.
