Question about Google Tracking Disparities
byoung2: Hubpage visitor count will be higher because it counts requests on the server side, including page views where the user had Javascript disabled, or left the page before the Google trackpageview event fired.Google Analytics should accurately count visitors who have Javascript enabled, which is a subset of all users.  Even then, sometimes Analytics loads, but the trackpageview event might not fire before the visitor leaves the page (sometimes this results in a 0:00 time on site, if the pageview is counted, but the timer event doesn't fire).Adsense pageviews are usually equal to the number of Analytics pageviews times the number of ad units on the page.  So if you have 50 Analytics pageviews, and one ad per page, you will get 50 Adsense page views.  In your case, Hubpages randomly selects to show either your Adsense code or theirs, so you have 25 Adsense pageviews (and Hubpages has the other 25).  That's Hubpages' revenue sharing model, as described here:
