Banners Ecpm comparison

Which adnetwork works better for you using banners?

I am getting something near 1$ ecpm with admob (refresh set to 40s) I have “rainbow” Traffic with 17% USA.

How much are you getting with StartApp?

Is it Admob and Startapp compliant to have both banners in the same page?

I can’t remember the specification exactly, but its against Admob’s T&Cs to have more than one banner ad unit running on the same screen at the same time.
This may only apply to more than one Admob banner, but its likely to be theirs/any other banner ad.

To be sure on my network’s accounts, scim through their T&Cs.
