How do you measure page-views?
Every page your users visit on your website is counted as a page view. That means if a user visits your website and has viewed 5 pages (be it the same page 5 times or 5 different pages) then it is counted as 5 page views.
In other words, every time accessibility enabler java-script loader is requested it is counted as a one page-view.
Page-views are counted irrespective whether the visitors open the accessibility toolbar or not.
