Matt Cutts has been a great person, who I have been watching and learning regularly from. As a search engine optimizer, I wanted to be in track of the latest happenings. Matt Cutts' blog at http://mattcutts.com was one of the best source to be with. He explained very specifically what Google needs and does not needs. The inputs from him were GOD's word for us. And they were pretty accurate. A million thanks to Matt Cutts for them. Without those inputs from Matt Cutts understanding SEO couldn't have been easier for us.
