I run Adsense on all of my pages. I get about 5000 visitors per day, however I also get like 5400 or 5900 page impressions per day. Note that I am talking about page impressions.
Now, this would imply that each visitor an average is visiting only 1 page, or even less than one page, since I work on the site each day viewing more than few hundred pages. It's a content rich site and each page is a rich content.
Therefore, should I assume that in certain countries (may be India, China) Adsense is now showing any impressions, not even the public ads.
I had heard that in average each visitor visits from 2-3 pages. If 3 is correct in my case that means Adsense is showing only the 1/3 of my impressions.
How do you explain this problem and what would you suggest to do? If there are certain countries that Adsense is not showing anything what alternatives should I chose to monetise on those visitors?
