How could it be that you guys get hight eCPM? For me,it didn't work and I stopped promoting ads of Smowtion on my site any more. cpm: 3.683 clicked: 117 eCpm: US$0.19 Earned: US$0.70 And I have about 40% US traffic and 30% European traffic.
you have to use Smowtion ads for at least few days or so for testing because starting earning is very low. they will give you better and better CPC ad as you use them more!
One week is not enough, may be two weeks. Unbelievable one day i got a ecpm of 1.5$. But the ad filters are tedious.. takes time to block the adult dating site ad eventhough you block the category
