Users that find your rotator clean and easy to use would bookmark it to use in the future, whereas unsatisfied users would not come the second time. I suggest you limit your ads to only one first, and make the faucet load a full page, because currently it is squeezed that you even have to scroll sideways. Make it a normal full page, and make sure the faucets are paying, and you're good.
Faucets aren't really rewarding, so making a faucet rotator won't get you much also, I've stop updating my faucetlists for a long time too.
