Hey,
could you guys give me some hint regarding mobile popunder traffic sources with some nice volume?
I know so far: adcash, wiget, popads
Thanks in forward.
You have already listed a few solid ones. That should be enough to get started.
Once you find something working, test out popcash, zeropark, propeller, exoclick and gungomedia.
Note that all these sources are a bit different. Some are managed, adult or selfserved.
Do your research upfront.
