Ok. Well since you're using adsense the only answer for your low payouts is that your category sucks. The advertisers just aren't bidding high for the content network in it and there's little competition. Why did you choose to make a site about cancer for adsense? Did you do research or look at google trends to tell you that it was a good topic to hit? If you want ways to get legit target traffic you should check out the white hat subforum on here, if your'e just looking for any traffic at all theirs some good posts by harro on the topic. Just advanced search for "traffic" and member harro. LOok at this method too. I've used it with success to add to my daily income with adsense sites. If thats your aim its all about picking keywords without too much competition that people are doing searches for.
