I have the same desire back then but after hearing experience from those faucet owners here, I decided to change my plan instead and began focusing on other methods to earn bitcoin. Back then, there are really lots of faucets who pays well like 1,000 satoshis every hour but in just a matter of days or weeks, it become wreck. To give users a 1,000 satoshis every hour, the capital must be decent.
And can you please share to me what is the best ad provider (Coinad, Mellowad, A-ad or any other provider) in terms of payment and how easily they accept your site.
as was stated above,Adsense doesn't like faucets and loves to block your account after 3-4 months under any pretext
to profit form a faucet you got to have a decent hoster,preferably unique design and good bot protection
you have to balance payout vs profit on a weekly basis(sometimes even in 2-3 days when btc is volatile),know how to get traffic,analyse competitors and all that for under 300$ a month
without google adsense you will have to use a-ads,mellowads and other ad networks that are already saturated with faucets
so think twice before starting a faucet,you may earn some money,but the majority of faucets live 1-2 months,some even less
