How to fix wrong facts in AI answers

You cannot edit what ChatGPT says about your company, but you can fix the pages it reads. Find the wrong fact and its source page. Fix your page, ask that site to fix theirs, and check weekly.

Key points

  • AI repeats its sources. A wrong fact usually comes from a page. Find that page before you change anything.

  • Your own page comes first. In our test, 4 of 10 answers cited only other sites. The maker's pricing page was in their results.

  • No instant fix. Nobody can say when the answer changes. Check the same question weekly.

Why does AI get facts about my company wrong?

AI writes from the pages it finds and from what it learned in training. If those are old, unclear or about someone else, it repeats them.

  • Your own pages disagree

    An old price page and a new one both stay online.

  • Other sites are out of date

    A review, directory or old press article still shows last year's facts.

  • Training memory is older

    The model learned about you before your change.

  • A close name

    AI joins facts of another company with a similar name.

  • No page answers it

    AI fills the gap and makes up a fact.

Each cause has its own fix. So the first job is always the same: find where the wrong fact came from. For a name mix-up, read when AI mixes you up with another company.

What did our test show about price answers?

The same price question got two different answers. When AI skipped the maker's own page, other sites decided the number.

On 4 November 2026 we asked an OpenAI model one question in 10 new chats. What does one email marketing tool cost per month for 2,500 contacts? We asked for one price in US dollars and the plan name.

  • The answers split 5 and 5 between two prices for two different plans.
  • All 5 answers with the higher price cited the maker's own website. 4 of them cited its pricing page.
  • 4 of the other 5 cited only other sites.
  • In all 4, the maker's pricing page was in the search results. AI did not cite it.

How do you find where a wrong fact came from?

Open the links next to the wrong claim. The page that says it is the page you need to fix.

  • No link? Ask: "Which page says this?"
  • Still no page? Then AI may have made it up. See the section on made-up facts below.

How do you fix wrong facts about your company in AI answers?

Work from your own site outwards. These five steps fix the source, which every AI engine reads.

  1. 1

    Find the wrong fact and the cited page

    Use the check above. Keep a short list: fact, engine, date, cited page.

  2. 2

    Fix your own page first

    Put price, plan names, address and key features in plain text on one clear page. Take old pages down or redirect them. Show an "Updated" date.

  3. 3

    Ask the cited site to correct it

    Send a short, polite note with the right fact and a link to your page. For directories, edit your own listing.

  4. 4

    Send feedback in the AI app

    In ChatGPT, use the thumbs-down button under the answer and say what is wrong. This sends feedback to OpenAI. Your pages stay the lasting fix.

  5. 5

    Check again every week

    Ask the same question on the same engines. Write down the date and the answer.

What if AI shows old facts about your company?

Old facts often come from training memory or from pages nobody updated. Fix the pages, then help search engines find the new version.

  • Change the facts in the visible text, not only in markup.
  • Give the changed page a true "last modified" date in your sitemap.
  • Ask Google and Bing to crawl the page again.
  • Update your profiles and directory listings on the same day.

What if AI makes up facts about your company?

AI is more likely to make up a fact when no page answers the question. So publish the answer yourself.

Look at the questions where AI guessed. Write one short page or FAQ entry for each, with the answer in the first sentence.

Example: AI guesses whether your tool has a German version. Add the FAQ line "Is Example Co. available in German?" Answer it with a clear yes or no.

Questions about wrong facts in AI answers

How long until ChatGPT shows the corrected fact?

There is no fixed time. With search on, ChatGPT can use your new page once it reads it again. For Google, crawling can take a few days to a few weeks.

Does thumbs-down feedback change the answer?

It sends your feedback to OpenAI. We know of no case where one rating changed an answer for everyone. Fixing the cited page works on every AI engine.

What if the site with the wrong fact does not reply?

Make your own page the clearer source: one page, plain text, a date. Ask again after a few weeks. Directory listings you own you can fix yourself.

Does schema markup fix wrong facts?

Not on its own. Google says AI features need no special markup, and markup must match the visible text. Fix the text first.

Can AI get facts wrong even when my page is right?

Yes. It may read another page first or mix you up with a close name. That is why you check the cited links, not only the answer.
