I've been following the advice you guys have been have here and I have my first profitable campaign on my hands. It's been 3 weeks since I started now. I tried ppc-coach but i found that his techniques were all easily accessible for free and the support/tools weren't all they were cracked up to be so I'm probably not renewing there. Anyways so far on my new campaign 4 leads for 25$'s and only 15$'s spent in advertising.
