ChatGPT Remembers Old Domains: Site Migration Means New URLs May Miss AI Answers
kyliebytes · x · 2026-08-19
SEO expert Lily Ray found that ChatGPT's fan-out queries used site: searches against a well-known brand's old domain — even though the migration happened over 6 months ago and was handled well.
The old domain appears to live in ChatGPT's memory, and Google/Bing site: searches on the old domain don't surface the new domain's URLs. So a migrated site's new URLs likely won't appear in ChatGPT responses unless discovered via other fan-out queries — a serious hazard for domain migrations in the AI search era.
