There's a short list of people in the SEO industry who you'd want to be in the room for them to speak, no matter what the topic was. Bill is on that list. I remember popping into some session late during an old SES and hoping that Bill hadn't spoken yet. Lucky me -- lucky us! He hadn't. And then in typical Bill fashion, he shared about 3 presentations worth of expertise and ideas in his talk. He does the same thing on his blog. And back in the early days of local SEO, when it was still a novelty to most, he was always a willing participant and giver in various email conversations, blog comment conversations, conference hallway conversations, and more.
And so when the question is, "How has Bill Slawski helped you?," the answer is that he always gives his time, energy, and smarts to the community. And for that, we're all eternally grateful. Get well, Bill. We're all praying for you, thinking about you, and rooting for a speedy recovery. God bless!
