That is alot but to those faucet that you are having you can only get $50 per month?
Yeah, as I see from Google Analytics, mostly people visit Bitcoin, Dogecoin and Ethereum faucets. Other coins like Blackcoin, Bitcore, Dash and others aren't popular, so I can't earn decent ref commission from these faucets.
And you can't use Google Adsense on faucets. Having quality content doesn't helps. Though, I'm not sure about faucet lists. Probably I can use it on my blog/faucet list, because I have quality original content. But I wouldn't risk to try, because I don't want to get ban.
Well, I have seen two site lists even a faucet who is actually running google adsense on their site. Since they have other contents that are actually acceptable in google's policy
Is it even profitable these days? I used to remember back in the 20k BTC days that faucets (especially on faucethub) were making their money by referring other faucets through their own faucets. Kind of like a vicious circle in a way.
I am not sure tho I think it is still quite profitable that depends on your marketing strategy
