I own a few very small internet companies, and a brick and mortar medical technology research and development firm. Also do consulting, both for internet companies, and clients who need legal help. I also do domaining, own over 1400 domains acquired since 2002. For my internet companies, my SEO is primarily PPC, and for my consulting websites, all organic SEO. I have a couple of sites in the top 100,000 ranked for the world. I'm pretty much white hat only, creating backlinks is about as black as I get.
