first off I'm no PPC pro by any means but have been learning some stuff lately. My primary biz has been large scale blackhat seo but I decided there's some real money to be made in PPC. With that said one of the primary things I've found is it's all about tracking conversions. What keywords convert and when. If you know these numbers you can tweak your bids for the keywords that really pay and ditch the words that are duds. Also knowing when you conversions come is a good thing. I was able to increase my ROI quite a bit by shutting off the campaign at certain times. Hope you enjoy!
