Top Page Views also includes detail pages (ex: news detail, event detail, etc.) However, the tracker sees all views of a single detail page type as the same page. For example, if the News Detail page appears in your Top Page Views, the number includes all news stories as opposed to showing a separate page for individual news stories.
This is because the tracker strips the arguments, which include the news ID number, from the URL. This means all news item views show in the tracker as the name of the detail page it displays on and therefore does not distinguish one news item from another.
