Can anyone recommend a good course on traffic? I have a friend who makes 7 figures/year from IM and his mantra is 'learn to push traffic.' I've looked at a bunch of the 'guru' courses but most of them are geared toward generating revenue from existing email lists. (of course, there's a lot of value in some of these courses and I am watching them) I need to find a good course on learning how to generate traffic, preferably PPC traffic. Any recommendations?
