Here is my site: http://www.thisblogwillpaymymortgage.com/ It was a blog about making money online to start with but realised quick that that is a saturated place to be. So now I thought I just just take the blog name literally and change the target audience to people that want to pay off their mortgage quick. I was already picking up searches from Google about that a few months ago just because of the blog name. Anyway, I wondered which affiliate products would be good for people that are looking to pay off their mortgage quickly?
Well, you have some ebooks on this on Clickbank and PayDotCom. Also, perhaps you can promote financial related services which most of them are available on CJ and Shareasale.
That specific category is difficult, because everyone is trying to pay off their mortgages, I see that as a tough niche to really decipher. But most people looking to pay off their mortgage, are probably looking for other refinancing options. if you can find some affiliate programs that offer credit restoration services,that might be one option.
You might want to try promoting paid surveys and other make money online offers. In addition to the morgage niche, your readers and traffic will probably be interested in these money making offers as well. If you're already getting search engine traffic, continue to build and it may not matter that your niche is competative. With the right optimization, anything is possible. Take care!
