On "Google: Site Move Outcomes Impossible To Fully Know Ahead Of Time"

Mueller's right to pump the brakes, but the real issue is that Google's ranking transfer mechanics are still opaque enough that moving domains remains a calculated gamble rather than a documented process. You can follow the migration checklist perfectly and still lose traffic for months because search relevance signals, user behavior patterns, and crawl prioritization don't transfer in any predictable way. Unless you're fixing a genuinely broken domain situation, the SEO risk of a vanity rebrand almost never justifies the upside—and Google can't tell you otherwise because they honestly don't know how your specific site will respond.
