John Mueller
Search Advocate at Google
Zurich, Switzerland · Swiss / German
John Mueller is a Search Advocate at Google, based in Zurich, Switzerland. For more than a decade he has been one of the most public faces of Google Search, running office-hours hangouts, answering questions on X and Bluesky, and translating Google’s public guidance for webmasters, developers, and SEOs.
Before joining Google in 2007 he founded and sold the sitemap-generation tool that became part of Google’s webmaster tooling. He has since become the go-to voice on how Googlebot crawls, how Search handles duplicate content, canonicalization, structured data, and thousands of smaller-but-load-bearing questions the SEO community asks.
Across office hours, podcasts, conference talks, and daily social-media replies, John has probably answered more public SEO questions on the record than anyone else at Google. His style is deliberately understated: he rarely gives a hard yes or no, preferring to surface the trade-offs and the edge cases that matter, which is exactly why SEOs keep coming back to him.
John also took part in SEO Charity’s SEO for Paws 2 online charity conference with the anecdote session I’ve Seen Things w/ John Mueller, a personal look at what he has seen across years of watching Search from the inside.
