if you're new to ppv then you should be signing up for the coaching.
I joined right back when the site was first launched and now ppv consistently gives me $20-30k profit per month.
It took me 6 months of testing and tweaking campaigns to get to this level, and ppv coach sped up my learning curve dramatically.
If you put your ego to the side and are prepared to learn some new skills then ppv can be a nice addition to your arsenal of traffic. But most ppc'ers fail at ppv because the traffic and offers that convert are very different.
Most guys who joined wanted the exact offers, urls and keywords to bid on. As if.
Instead what you are taught is techniques. For $50 a month it has to be worth a month or two of anyones time who wants to make ppv work.
