martinibuster hit the nail on the head. Although I assume there are other good scenarios, the one that works best from my experience is having loads of traffic from one specific type of visitor. Will I tell you what type that visitor is? Nope, sorry, but many of you probably already know. I just figure there's no good reason for me to blab about it. Still, if your site attracts that group of people, and your site can attract more and more of them, your adsense earnings will almost always go up and up and up.
