High CTR = Low CPM? Oh yeah (2)
We know high CTRs fetch cheap clicks when bidding CPC....but here's something for those didn't know that it applies for your CPM campaigns as well:
The ad with the 0.52% CTR gets about 5 clicks for $0.18 (3 cent clicks)
the ad with the 0.24% CTR gets about 2 clicks for 0.45 (22 cent clicks)
When bidding CPM, a high CTR doesn't just mean more clicks → it means more clicks at a lower CPM 
At the end of the day every network is just maximizing their eCPM, once you learn to master this metric you won't care if your camps are CPC or CPM
