Correct the wrong facts ChatGPT tells about you

Why it matters

A customer who asks "is [your restaurant] open on Sunday?" has already chosen you. If the answer gives last year's hours, an old address or a dish you stopped serving, they turn up at a closed door or go somewhere else.

AI assistants build their answers from what they find online: your website, your Google profile, listing sites, old press articles. When those pages are out of date or disagree with each other, the answer can repeat the wrong version. When a fact is missing, an assistant may still answer, and the answer may be a guess.

Google says plainly that its AI Overviews can make mistakes. You cannot edit an AI answer directly. What you can do is make the true facts easy to find and the same everywhere.

Before you start

Have these ready

• Your scorecard from Guide 01, especially the questions that contain your company name and the "Wrong facts about us" column. No scorecard yet? Do Guide 01 first; the quick check takes 30 minutes.
• A login to your website editor (WordPress, Webflow, Wix) or your web developer's contact.
• The logins for your Google Business Profile, Bing Places, LinkedIn page and any listing site where you appear, such as Editus or Tripadvisor.
• Your details from the Luxembourg trade register (RCS), or your RCS number so you can look them up.

Steps

Find and fix the wrong facts

1. Write your fact sheet

   Before you can spot a wrong fact, you need one agreed version of the right ones. Fill in this template once, and have a colleague check it. Every later step compares against it.

   fact-sheet.txtCopy

   COMPANY FACT SHEET (last checked: ____-__-__)
   
   Legal name (as on the RCS):
   Trade name (what customers see):
   RCS number:
   Address:
   Phone:
   Email:
   Website:
   
   Opening hours
     Monday to Friday:
     Saturday:
     Sunday and public holidays:
   
   Services or menu highlights (one per line):
     -
     -
   Prices or "from" prices:
     -
   Languages spoken:                (e.g. Luxembourgish, French, German, English)
   Areas served:                    (e.g. Luxembourg City and the south)
   Founding year:
   Key people and their roles:
     -

   Take the legal name and RCS number from the trade register itself. The RCS is public and run by Luxembourg Business Registers; you can search it at lbr.lu by registration number or company name. If a published fact has changed, such as your registered office, guichet.lu notes that changes to published information must also be published through the RCS (guichet.lu).

2. Ask the assistants about you by name

   Use the questions from your Guide 01 scorecard that contain your company name, such as "Is [Company] open on Sunday?" or "Combien coûte le menu du midi chez [Company] ?". Ask them the same way as before: a private window, a new chat for each question, and the date written down.

   Compare each answer with your fact sheet. Write every wrong fact in a small table with three columns. Here is how a filled-in table could look:

   What AI says	What is true	Where it probably comes from
   Open Sunday 10:00 to 18:00	Closed on Sundays since March	Old hours still on the Google Business Profile
   On Rue de l'Alzette	Moved to a new address in 2025	A local listing that was never updated
   Lunch menu from €14	From €17	A 2024 menu (PDF) still on the café's website
   Speaks French and German	Also English and Portuguese	Missing everywhere; the website does not list languages

   Example with a fictional café in Esch-sur-Alzette.

   When the wrong fact is your own old page

   A hotel renamed its restaurant and stopped offering half board. ChatGPT and Copilot still named the old restaurant and offered half board, because an old offers page was still live and still stored in Bing. Nothing on any listing site was wrong. The fix was on the hotel's own website: remove the page, point its address to the new one, and ask Bing to read it again (see Guide 03).

   Example with a fictional hotel.

3. Find where each wrong fact comes from

   Fill in the third column. Fixing the source is what changes the answer over time.

   • Open the links the answer cites. Most assistants show source links next to the answer. Open each one and look for the wrong fact.
   • Search your own website for old pages. On google.lu, type site:yourcompany.lu followed by the wrong value, for example site:yourcompany.lu 14 or an old phone number. Google notes the results are not always complete, so also ask whoever runs your website.
   • Look for old PDFs and forgotten pages. Menus, price lists, brochures, job ads and old news posts often keep old facts. Ask your web person for a list of every file uploaded to the site.
   • Check your listings. Search your business on Google Maps, Bing, and the listing sites from your scorecard's "Sites cited" column.

   Sometimes you will not find any source. Then the fact is probably missing online, and the fix is to state it clearly in step 4.

4. Fix your own website first

   Your website is the one source you fully control, so make it the clearest and most complete.

   • Make one page with all the facts. Use your About page or create a page called "Practical information" (or "Infos pratiques", "Praktische Informationen"). Put every line of your fact sheet on it, as plain text and not inside an image.
   • Put the core facts in the footer. Name, address, phone, email and, for companies, the RCS number at the bottom of every page.
   • Update or remove old pages. Replace old menus and price PDFs with the current one, or delete them. Update team pages and old opening-hours notices.
   • Check every language version. A French page with the new hours and a German page with the old ones gives assistants two answers to choose from.

   Tell your web developer before deleting pages. They may want to redirect the old address to the new page, so visitors and links do not end on an error.

5. Fix the same facts everywhere else

   Copy the facts from your fact sheet, word for word, into each listing. Start with the sources you found in step 3.

   • Google Business Profile. Go to business.google.com, select Edit profile, change the business name, "Address and pin location", "Hours" or "Phone number", then select Save. Google reviews changes before they appear. Changing your name may mean verifying your business again, and moving to a new address means you must verify it again. Google help
   • Bing Places. Update the same fields in your Bing Places listing. Copilot looks things up through Bing.
   • LinkedIn page. Check the address, website, size and description.
   • Listing sites. Editus, Tripadvisor, booking platforms, your trade association or chamber. Each one you correct removes a conflicting version.

6. Report the wrong answer to the assistant

   Some assistants have a feedback button under each answer. Use it for each wrong fact, and paste the correct fact in the text box.

   • Google AI Overviews. At the bottom of the overview, click the thumbs down, then "Report a problem", choose the category that fits, add details and submit. Google help
   • ChatGPT. Tap the thumbs down under the answer, then select an issue and follow the prompts. OpenAI's help page describes this for reporting content; it does not say how reports of wrong business facts are handled. OpenAI help

   Be realistic: feedback alone rarely changes answers quickly, and neither company promises to act on a single report. Fixing your website and listings in steps 4 and 5 is the part that lasts.

7. Check again after a few weeks

   Ask the same branded questions again, in the same assistants and languages, and add a row to your table for each answer. Write down which facts are now right and which are still wrong.

   Assistants and search engines read pages again on their own schedule, so there is no fixed date when answers change. If a wrong fact stays, go back to step 3: there is usually one more page or listing that still has it.

Check it worked

Confirm the facts now match

Open your website, your Google Business Profile and your main listings side by side with the fact sheet. Every line should be identical, down to the phone number format and the opening hours.

Common mistakes

What usually goes wrong

• Only sending feedback to the assistant. If the wrong fact is still on a page online, the answer can keep coming back.
• Fixing the website and forgetting the listings. An old Google Business Profile or listing keeps the conflict alive.
• Leaving old PDFs online. A 2024 menu that nobody links to can still be found and read.
• Writing facts in slightly different ways. "Mon to Fri 8 to 18" on one site and "8:30 to 17:30" on another gives assistants two versions to choose from.
• Updating only one language. Check the French, German and English pages, and the listings in each language.
