How do you manage search results for a company rebrand?

A rebrand is one of the most technically demanding moments in reputation work, because the company itself is changing while the engines have years of accumulated signals pointing to the old name. The sequence: set up 301 redirects from every retired brand domain and key URL to the matching new location, so the existing link value carries over. Update Wikidata first, because it spreads faster than Wikipedia; then update the Wikipedia article through Talk-page edit requests with sourced citations of the rebrand. Work with Google to refresh the Knowledge Panel through its verified entity-correction process. Refresh every authoritative directory listing (Crunchbase, Bloomberg, industry directories, LinkedIn) within the first two weeks. Publish definitive content on owned properties establishing the new identity, with structured data (machine-readable tags that tell search engines what a page is about) linking the old and new names through an alternate-name field. Track the whole transition through IMPACT, working on the sources the engines read rather than on the engines themselves, so any signal that fails to update can be fixed before it sets.
