Counting hits

* Hit - A request for a file from the web server. Available only in log analysis.
* Page View - A request for a file whose type is defined as a page in log analysis. An occurrence of the script being run in page tagging. In log analysis, a single page view may generate multiple hits as all the resources required to view the page (images, .js and .css files) are also requested from the web server.
* Visit / Session - A series of requests from the same uniquely identified client with a set timeout. A visit is expected to contain multiple hits (in log analysis) and page views.
* Visitor / Unique Visitor - The uniquely identified client generating requests on the web server (log analysis) or viewing pages (page tagging). A visitor can make multiple visits.
* Repeat Visitor - A visitor that has made at least one previous visit.
* New Visitor - A visitor that has not made any previous visits.
