The definitions of the terms collected page views, licensed page views, and analyzed page views are as follows:

Collected page views are the raw hit count from the log files that are processed.
Licensed page views are the total number of collected page views minus non-page view extensions (.gif;jpg;bmp;png;wbmp;jpeg;css;js;dtd;asmx;ascx).
Analyzed page views are the licensed page views minus the data that is removed by the use of any filters AND those pages that are not defined in the Page File Types. The majority of the reports only include hits/Page Views from the log file that contain 200-300 series return codes. All 400-500 series return code page views are only represented in the error reports.
