I'm starting to see how difficult it is to rank #1 on any niche, whether its big or small. With that said, even if ranked 1, adsense gives such puny earnings. Let's take a modest 4,400 exact monthly search keyword. #1 gets about 40 to 50% of the traffic... and of that traffic, maybe 5% of them convert (click on ads). Most CPC on adsense, even when it says a few dollars per click, really just give you .25 or .50 per click. So if you manage, through a lot of money and time, to rank #1 for a 4,400 exact search kw and you get .50 per click... That's 4,400 x 50% x 5% x .50 = $55 PER MONTH! That's fucking pathetic, especially factoring the work and money it takes to get #1. And that's if you're lucky enough to get to #1.
