I see all the time that I get 1 cent when user clicks on the ad on my site (google says that they keep 50%, which means the ad cost to the marketer was 2 cent).

Then how come I cannot find a way (I have tried everything that people have mentioned on the internet to do do it) to get any traffic for 2 cents.

So, there seems to be a gap here where I am charged at least 10 cents, but paid only 1 cent..per ad

Are you guys seeing the same thing?
