The best way to go would be to sign up to
Bitter Strawberry and
Sex Goes Mobile, and see everything, for yourself.
Other ad networks, which are good for this, would be
First Mobile Cash, and
VPS Mobile, but these are somehow more advanced.
I know a lot of people, who have been doing it for 5+ years, and they are making 50% of what they should be making, because they dont have correct mobile versions of all of their sites. 50% from desktop, 50%+ from mobile is what it should be now.
Bitter Strawberry +
Sex Goes Mobile (at the same time, or ad rotation) + mobile popunder from
Plugrush are the best for this.
