I just used your tool and now know why you have the big empty space to the right) You have picked one of the roughest crowds to sell to. In an earlier post I suggested that you mask the url of the clickbank products you were promoting. Since you have your own domain, it is easy to do. For example, if you were selling a product called SEO Buster, you could have http://www.google-your-rank.com/SEO-Buster or /SEO-Buster.html or SEO-Buster.php. Then put your CB redirect in there. It would be interesting to see if you got more click throughs doing that. I would expect you would. But that does not mean you would get any more sales) I really can't think of anything that would be any good except selling your own product(s). Then they would have to be really good. If you created a report that gave some useful tips or strategies, or whatever, you could try selling them for a few bucks, say $11.99 or $19.99 or whatever. The other thing you could do is to try to think of something you could do to get a few bucks using the tool you created. Right now you return 300 results max. Maybe let the free tool return the first 25. If someone wants more, charge them a small monthly fee. But if you do that, I recommend adding more functionality to the tool. Maybe return all of the urls and the number of backlinks to each. You will have to really make that tool valuable before this crowd will part with their money) Good luck!!
As usual you give great ideas I am going to make further changes to set things into action ... I was wondering you said "You have picked one of the roughest crowds to sell to" is it a fact?
