I've found a guide online that makes $3000 a month and based on the forums it seems pretty reputable and easy to do. It required adsense and that's pretty much all I know. At the moment the guide is $50 but the owner said he is going to increase it. I literally have $3 in my account or else I would have bought it and shared it. If anyone is interested I can send the link for the guide if they can share it with me.
