I have just signed up with rightmedia and I am running CPM ads from 4 different networks on my site. Awstats and Google Analytics show an average 220,000 page views per day on my site which is correct because it is a social networking site, about 80 page views per UV. Having 3 cpm ads on most pages and 2 on others, this gives me an average of 2.5 ads per page view, or 2.5 impressions per page view. 220,000 page views = 550,000 impressions right??? Then why am I only getting about 40,000 impressions a day!!! Thats like having 0.25 impressions per page view. Am I being screwed? Is something wrong? Is this normal? It doesn't make sense.
Could be that they are only counting unique page views (i.e. if someone sat there going from page1 to page2, it would show up on analytics as them visiting lots of pages, but in actual fact, it's only 2)
