Maybe I find some companies to advertise in my book. Maybe some sort of contract, 5 Cent per copy downloaded. But how to proof how many dowenloads by real people? What company could provide a better service than Google, when it comes to the question, download by real people?

I can't really see how Google could intercept that relationship in order to make money. So why would they do this?
