I'm starting to expand to do some Adwords marketing post-penguin. I need to spread it out more. Organic is too volatile now and into the future. So, I'm going to give in a little and give G some of my money. However, the interface, admin panel, etc... is insane. I'm having fun learning, but losing money, I'm sure. I read a few pdfs, but wondering if there's any arbitrage experts here that can give some pointers...
I have a few adwords coupons, so I figure, now's the best time to learn for free...
