I have been using mobile advertising for a while and this webpage will compare various mobile advertising which I have used.
All Values are relative to Google Adsense thus not actually giving figures.
The Higher the Rating, the better it is. For example a rating of 0.25 compared to 1.00 you would need 4 times as many visitors to get the same amount of money.
The figures may not be the same for everyone but I expect it to be similar.
