Just totally hypothetical, a total random thought I had. Right now, I'm thinking that those faucets really don't earn as much profit as we might think unless they do Adfly and redirects, which would of course annoy users.
They earn a very small amount per visit. The money comes from quantity. You need to have some reason that brings people in to yours others don't have or is new.
I think its going to be hard to get a lot of people to visit it. Personally I don't bother with faucets money us just to small.
