heres some tips from me because i opened a faucet about 1 month ago

1. dont use google recaptcha, solvemedia is better for preventing bots. recaptcha seems to have no effect. my faucet was being raped by bots for over 0.05 BTC per day until i switched to solvemedia then it was reduced to 0.01 per day

2. you will probably need google adsense to make profit or break even

3. start with lower rewards and experiment to see how much rewards you should adjust to in the future based on your earnings from ads

4. make it hard for bots to use your site but be sure to make it easy enough for humans to still claim your faucet or else you will also lose real traffic
