I met Bill through his tweets about Google patents thanks to another Spanish SEO, Natzir Turrado.

The value that he has always brought to the SEO community is priceless.

Without barely knowing him, I asked him if he wanted to participate in an ebook called "SEO for ecommerce" that I edited 2 years ago. He immediately said yes! To me, it was amazing that someone of his authority wanted to participate in something that I was creating.

Get well soon, Bill!
