I am looking for an ad network which provides good eCPM rates for Asian Traffic(India, Bangladesh, Philippines).
CPM rates from these countries are really low. You will get eCPM not more than $0.10 that's sure. But most networks will even pay less. I will suggest try adversal or propellarads. They are both are good and provides reasonable CPM rates.
If you don't get approved by Exponential then its good to say that Adversal is your only option here.
Adversal is the best for Asian traffic.
