I see that you're already using shortlinks, that's good. Another suggestion - it's not worth to have so many A-Ads banners on your website because it doesn't helps to improve income - you will stell get pretty much same income like having just 1 A-Ads banner.
Another thing which aren't related to monetization - it would be be good to change text color from white to black, because now your faucet ballance, rewards and timer is hardly visible.
