Yeah that is a great niche, been getting into that recently, especially in the states with everyones money problems.
i do good on car insurance and mortgage... i did student loans and the EPC on that is lower. Now i work more on insurance and mortgage. I was recently intoduced to Adsense on Youtube. I may explore this option. But need to make my own HD videos LOL.
It doesn't really matter all that much. I had a HUGE network of autoblogs, Adsense was getting around $1/day from all of those. They did great for about 3 months before I sold them.
