Hopefully someone will have the knowledge and insight I lack to answer this. I'm also frustrated that there's no clear way to ask Google this question.
I've recently started to create hubpages to hopefully bring in some more revenue streams on the side - I'm not deluded into thinking I'll make a million bucks mind you, but the articles are high quality and informative, so I feel I'm providing a valuable service.
But the visitor metric tracking disparities between Hubpages, Google analytics, and google adsense are terrible!
On one particular hub, I see from the past seven days:
Hubpage visitor count: 82 page views
Google analytics: 50 visitors/65 page views
Google Adsense: 25 pageviews. (wtf!?!?)
Tracking codes and everything seem to be installed right (Hubpages does not make this hard). It would seem like Google's trying to game me. What's with the disparity? Is this because of ad-blockers?
Note: I've also seen this disparity in Google's own tracking with my own self-hosted sites in the past. So does anyone have any insight in to what's going on?
