Question to anyone who preaches SEO: how much time/money do you spend on your SEO? Because in my experience it is way too much time and money that goes towards something which is quite uncertain, whereas with PPC it's very quick to make a site (and cheaper to get someone else to do it than with a SEO-site because you need way less content) and all your money goes towards testing keywords which give you data that you then use to make a profitable campaign from - a campaign that often lasts for a long time.
