No, the channels are there so you can assign a separate channel to each site or each section of a site to see where most of your clicks come from. If you want to make more, try placing ads above the fold. A medium rectangle front and center usually works best.
You get no extra money from it. It is there to help you separate different sets of ads. If you either have different websites or different pages, you can see how much money you r getting from each channel.
