Thank you. I heard Google banned some faucets from their ad networks so I don't think it's the way to go. And it is actually a faucet for bitcoins and I want to get bitcoins in return from the ads.

Yeah I will definitly use this DashAD then in addition to my current ads.
I can suggest you a ad network, too.
It is traffic2bitcoin.com. The cool thing: It actually doesn't display ads. You get paid for integrating a invisible iframe in your site which is giving traffic to the "advertised" site then.
The most profitable ones are (ranked):
1. coinmedia
2. adbit.co
3. a-ads
However a-ads is great because you only need to provide a withdrawal address no registrations. And it has a very low minimum payout of 10k Sats.
