Pop ups generate for me good money even better than other ads at the moment, This why i want to enable pop ups in my faucet for two weeks because i have only 1.5$ in my wallet so I have to use all availabe ads services.
I know that and every faucets needs ads to became alive but other faucet owner keeps rocking the faucet world today even without those annoying pop ads. Just think of an idea where you can keep your ads organized. And yes the previous post is right , you need some other income to make your faucet alive without relying too much in the ads.
You've got examples of other ways to make money with a faucet? The only possibility I can add is that some kinds of CAPTCHA-features do pay the owner of websites some small amounts of money. These CAPTCHA's then show also ads etcetera, you should Google for this .
At this moment, I can not think about other ways to generate an extra income for faucets rather than advertisements (- you might also want to consider selling banners etc to Bitcoin / Altcoin / Gamble related websites etc if you have enough visitors).
