I tried search but couldn't find anything useful. I'm looking for methods/guides that involve PPC or paid traffic generation. Adwords, Bing, premium traffic networks - anything. I'm willing to invest $$$ in PPC but I don't want to gamble and make an educated investment. The idea of email/zip submits CPA + PPC. If each email/zip submit earns me $1 and my CPC is less than $0.50, that's pretty good enough but I don't know the first thing about PPC so I want to learn that first. Hence, looking for something useful. Training material. Feel free to link me to some useful methods/guides here or even proven (but free) training material outside of the forum. Thanks a ton!
