So I've decided I'm going to start out trying some PPC affiliate marketing. I don't know whether it would be better to just start by experimentation or get some solid knowledge through some courses. Right now I know how to setup Adwords campaigns and all... is that enough through to start making money? Or should I join one of these courses like PPC Coach or Ubercamp. Or can someone suggest a quality ebook maybe that might help, as I'm not too hesitant to invest in a solid guide. I appreciate your suggestions!
