No offense to bobbylove321's recommendation but Pay Per Click Formula 3.0 is a joke. Gauher Chaudhry tells you to advertise on 7Search as a staple of making PPC profits. The #1 rule in PPC is quality traffic is key. 7Search does not have quality traffic. His other third-tier engines he recommends may have quality traffic but may not too. When people say they want to do PPC, they generally mean they want to advertise using Adwords and Adcenter. Why would you pay for a $1,200 course when Adwords has all the information free online? It is literally everything you need to know.
I can't post links for who knows why. I've been a member of this forum for years now. Anyways, go to Google and type in "adwords exam study learning center".
I also follow Brad Geddes. He knows his stuff. PPC Hero is a decent blog.
