The ROI on PPC vs. Affiliate Marketing

My friend Damian Raffele (AKA D-Dog) shared this very cool site with me called Marketing Experiments Journal. They have an interesting article on The ROI on PPC vs. Affiliate Marketing. People told me I was crazy to rely on affiliates for CMPUniversity and to give them such a big commission, but the research of this experiment proves my point. Given the choice I will invest in people and the power of building relationships (key 5) every time.
