I used to read lots of article at the beginning of my SEO journey, I knew most of them was bluff with no proof of there concept. One day I saw Bill mentioned in an AMA session in a known SEO group. He was answering everything with solid data. Then I started reading the stuff he provided on different sites. After reading his contents and interpretations of different patents I understood what information I need to absorb and what not to. Believe me or not I have gone after people showed them patent information in a way they understand. And landed a few of them. Still, I wait for new updates from the bill. I am always grateful for the bill.
