Rebrand or domain move: stop AI from searching the old name

You changed your domain or brand, and an AI tool still searches the old name. Below: the one weak piece of evidence we have, then a checklist based on Google's site move guide. We read the sources on 26 October 2026.

The one observation we have

On 19 October 2026, SEO specialist Chris Long (@chris_nectiv) wrote on X that LendingClub rebranded to Happen Bank 4 months earlier, yet ChatGPT still runs "site:" searches on the original brand. In the same thread, Lily Ray wrote that in some cases ChatGPT may generate site: queries from outdated training-data knowledge, and Chris Long replied that this is his guess too. A user named Brenden House said Lily Ray had found the same thing in August on a domain move more than 6 months old. That is a third-hand report; we did not see Lily Ray's own post.

These are personal observations and guesses. The mechanism is unknown. We found no source saying redirects fix this or fail to. We read the visible text of the X page but could not verify the screenshot or all the replies. So our confidence is medium-low, and we split the list below into two parts: the documented part and the untested part.

A. Documented: moving the pages

Google's guide to site moves with URL changes (last updated 20 August 2026) says:

1. Prepare a mapping. Write the new URL for each old one. You can pull your most important URLs from your sitemap and Search Console.
2. Set up server-side permanent redirects. Google recommends HTTP permanent redirects such as 301. Avoid redirect chains and point straight to the final URL.
3. Update canonical and hreflang. Once redirects are live, canonical tags on the new site should point to the new URLs. If you use hreflang, change those to the new URLs too (for bilingual sites: hreflang and redirects).
4. Upload a sitemap with the new URLs. Google says a sitemap can speed up discovery.
5. Submit a change of address. If the domain or subdomain changes, use the Change of Address tool in Search Console for the old site. Do it for every verified variant of the old domain (www, non-www, subdomains). Do not use the tool for HTTP to HTTPS, www to non-www, or path moves inside the same domain. Site moves cannot be chained: right after telling Google about A to B, you cannot report B to C.
6. Verify both sites. Verify the Search Console properties of the old and new site separately. Make sure your verification method keeps working after the move.
7. Keep redirects for a long time. Google recommends keeping them as long as possible, generally at least 1 year. From the users' view, consider keeping them indefinitely. The Change of Address help page says to keep them at least 180 days, longer if you still see traffic from Google Search.
8. Be patient. For medium-sized sites it can take a few weeks or more for new URLs to replace the old ones. 301s and other permanent redirects do not cause a loss in PageRank.
9. Change one thing at a time. Do not change the domain, the CMS and the design together.

Monitor traffic on both old and new URLs during the move. Requests reaching the old domain's logs also show which bots still go there. How to verify bots: AI bots in your server logs.

B. Untested: updating the brand and domain link

We found no source showing that the steps below fix AI answers. The logic is that even when pages move, pages and profiles that mention the old name may stay where they are. These are our suggestions, and we have not tested them.

1. Write a page that explains the new name. A plain sentence such as "X, formerly Y" belongs on the home page or the about page.
2. Use alternateName in Organization schema. Google describes alternateName as another common name that your organization goes by, and says name and alternateName should match what you use for your site name (Organization guide, last updated 8 September 2026). Schema details: Organization schema for a company site.
3. Update profiles. Renew the name and domain in Google Business Profile, social media, directories and partner sites. Third-party mentions that keep using the old name might also be a cause. That is a guess and is unverified.
4. Fix links on other sites. Ask sites that mention you often to point the link to the new address.
5. Do not let the old domain lapse. Google recommends continuing to pay for the old domain for at least a year, even after removing old pages, so others cannot buy the abandoned domain and use it maliciously.

Measure after the move

Ask AI tools a few fixed questions (brand name, domain, product name) once a week and record with a date whether the answer mentions the old name. Look in your logs for bots arriving at the old domain. Method: how AI answers pick brands. For how one question becomes several searches, see what is query fan-out.
