No, they earn a lot from clicks on ads and they still pay the same dust... what they earn from ad views is enough for what they pay to us (to be honest, as of now I only use freebitco, but I was a faucet user a few months ago).
They earn a lot from clicks??
Here's some stats from a friend of mine who own a small faucet:
Page views: 3016, impressions: 10474, clicks 9, Earnings: 1.72$ ..
Who much satoshis she give on that day? 0.0085 (worth 1.96$ right now) for a nice profit of...:
-0.24$
Oh.. i forgot something: she's gotta pays for :
Domain name, hosting and design
She told me she's gonna have to change something to be able to earn a little more.. A timer?, or some annoying popups? or maybe just shut down that faucet..
