I never had the chance to speak to Matt personally, but I always followed everything he shared while he was at Google. Before Matt there were so many unknowns about SEO (well, there still are, haha) but it was great to have someone letting us know that we were on the right track and to point out what not to do. I recall working with some devs at a Fortune-100 that thought SEO was pointless, but thanks to Matt it really put it on people's radars that it is a worthwhile pursuit when done correctly. Basically, he publicly validated what we already knew. So HUGE thanks to you, Matt!
