I see that faucet have only one source of income - Betcoin referral link. It's not enough to keep faucet. You should try some ad networks like A-ads, bitvertise and others.
I will try some ad networks soon. Thank you for advices.
You are using a Free domain. It will be good to buy a premium domain because a premium domain gives good impression on users mind.
In other hand your faucet reward is also low for 30 minutes user can get 100 satoshi only .
I can buy a premium domain. But it doesn't matter in this situation. This works too. By the way reward is not low for the chance to get these "300 (20%), 3000 (4,5%), 30000 (1%), 300000 (0,5%)"
