Half the problem is that people get confused and think they must make 'ultra clean' galleries to get listed and so make fuck all money. Sure galleries with little advertising (and the little there is is often banner top/banner bottom) will get you listed nearly every time. What the hell's the point though when it's making you no money? Mind you - doesn't help that so many TGP's decided they wanted galleries not designed to sell.
Simple answer is to build galleries designed to make clicks and sales. If you then miss the odd listing so what. At least you're making money.
I'll almost bet that with traffic that high you're making crap with minimal ads that are well away from all the pics.
