I try to apply but they don't accept my faucet and I don' have any Idea how much they will pay for click. If you know please share.
Bitmedia is a high quality Bitcoin ad network. They don't accept generic faucets. They do make exceptions for hybrid faucets, faucet + game sites having good quality traffic. Based on the source of traffic, they used to pay around 7000-20000 satoshis per click. It has decreased now, but still compared to other ad networks their rates are better. Coinzilla also offers a high CPC, next Mellowads, PPCadmedia is also good.
