It would seem to me that PPC is more of a short-term approach to make money online, where as SEO is the long-term approach, and when we talk about automating our online business, it is really SEO at work. Do you only make money using PPC?
I don't just use PCP, I make most of my money from CPM ads. I also run text link ads at the bottom of my site that I sell monthly, also I'm running pixel ads to sell information about my users. So there's 3 main sources of income, which I think is a pretty good idea. Don't put all your eggs in one basket. (Not to mention I'm with 23 different CPM networks, so if one falls, there's still plenty available to fight for impressions!)
i think PPC sites can actually create a good source of income. the only research you have to do on your part is to be able to pick a good PPC site to invest in. I kind of regret that because i invest quite an amount into a PPC site, and i did make money from it, but only problem is, the payout takes like forever.
