When ChatGPT gets facts about your business wrong, you can't edit its answer directly. Instead, find where the wrong fact comes from, usually an outdated listing, directory or page, and correct it at the source. Make sure your own site states the right facts plainly and isn't blocking OpenAI's search crawler. Then flag the answer and recheck monthly.
Where the wrong answer comes from changes the fix. If ChatGPT searched the web and shows sources, the error usually traces to a specific page you can find and correct, and the answer can improve within days or weeks. If it answered from what the model learned in training, with no sources shown, the error reflects older information that only changes when new models are trained. Your job then is to make the correct version easy to find whenever it does search.
The worked example is an illustrative sign maker with eight staff whose customers kept arriving on Saturday afternoons, after ChatGPT told them the workshop was open until 5pm. It closes at 1pm on Saturdays. Along the way are examples from a print shop, a clothing shop, a software reseller, an events company and a jewellery seller.
First, work out which kind of wrong answer you're looking at
Wrong answers fall into a handful of types, and each points to a different cause. These are the sign maker's own examples, plus one from another business where the pattern was clearer.
| Type | Illustrative example | Likely cause |
|---|---|---|
| Outdated fact | "Open Saturdays 9am to 5pm"; the old industrial-estate address | Old directory listings, an old contact page, a map listing never updated after a move |
| Invented detail | "Signs from $99, with free installation" | An old PDF price list still online, or the model filling a gap with a plausible figure |
| Wrong service | "Specialises in neon signs" (it stopped making glass neon years ago) | Old portfolio pages, reviews mentioning past work, similar businesses' descriptions |
| Mixed-up business | A print shop described with a franchise's opening hours and prices | A similar name, especially if your own listings are thin |
| Damaging claim | "Customers report the company has closed down" | A closed listing for an old address, a misread review, or an invented statement |
The damaging kind needs faster action and is covered in its own section below. The rest follow the same routine: record, trace, fix, recheck.
Record the error properly before you change anything
A screenshot of one bad answer isn't enough, because AI answers vary between people, sessions and modes. Spend 15 minutes building a proper record first.
- Test clean. Use a Temporary Chat in ChatGPT, or a browser where you're logged out, so your own history and saved memories about you don't colour the answer.
- Ask the way customers would. "What time does [business name] close on Saturday?" rather than "Tell me about [business name]". Ask each question three times; if the answer changes, note every version.
- Note whether it searched. If the answer shows sources or links, it used web search. Click every one.
- Try the other assistants. Ask Gemini, Copilot and Perplexity the same questions. If they all say the same wrong thing, the source is probably a widely used listing; if only one does, it may be that tool's sources.
The sign maker's record, filled in (illustrative):
| Question asked | Tool and mode | Answer given | Sources shown | Correct fact |
|---|---|---|---|---|
| When does [name] close on Saturday? | ChatGPT, search on | 5pm (2 of 3 times); "not sure" once | Two directory sites, one review site | 1pm |
| Where is [name]? | ChatGPT, search on | Old industrial-estate unit | An old trade directory | Current workshop address |
| Does [name] make neon signs? | ChatGPT, no sources | "Yes, it specialises in neon" | None | LED neon-effect only |
| How much is a shop sign from [name]? | Perplexity | "From $99 with free installation" | Old PDF price list on its own site | Quote only; fitting charged |
That record does two jobs. It tells you where to look, and it gives you a baseline to compare against next month.
Trace each wrong fact to where it came from
Most wrong answers repeat something written somewhere. Finding that somewhere is the real work. In rough order of how often they turn out to be the culprit:
- Your own old pages and files. The sign maker's "$99" came from a price-list PDF uploaded years ago and still findable by search, even though nothing on the site linked to it. Search your own domain for old prices, addresses and service names.
- Business listings. Map and directory listings with old hours or addresses. The sign maker found its old address on 14 listings, most of them created automatically years before.
- Industry and supplier directories. Trade association member lists, suppliers' "find an installer" pages, awards pages.
- Reviews and forums. A review from years ago praising "their brilliant neon work" keeps an old service alive.
- Similar businesses. If a business with a similar name exists, its details can bleed into answers about yours.
Two quick techniques help. Search the wrong fact in quotation marks together with your business name, which often finds the exact page repeating it. And ask the assistant directly: "Where did you get the Saturday closing time from?" With search on, it will often name the page; without search, it may admit it isn't sure, which tells you the answer came from training rather than a page you can fix.
Fix it at the source, in this order
Work from the sources you control completely to the ones you have to request. Time estimates are for a small business with one location.
| Where | What to do | Time |
|---|---|---|
| Your website | Put hours, address, services and how pricing works on your contact and about pages in plain text, not only in images. Remove or update old pages and PDFs, and redirect old URLs to current ones. | 1-2 hours |
| Your robots.txt and firewall | Make sure you aren't blocking OAI-SearchBot, and that your host or CDN allows OpenAI's published search-crawler IP addresses, which OpenAI says a site needs for inclusion in ChatGPT search | 15 minutes (ask your web person) |
| Google Business Profile | Correct hours, special hours, address, services and description | 20 minutes |
| Bing Places for Business | Claim or update the listing, now at bing.com/forbusiness; the new version can import from Google Business Profile | 20 minutes |
| Apple Business (formerly Apple Business Connect) | Claim the location and check the place card that appears in Apple Maps and Siri | 20 minutes |
| Directories and industry listings | Update or request corrections; ask for closure of listings at old addresses | 5-15 minutes each |
| Social profiles | Make bios, hours and links match the website exactly | 15 minutes |
OpenAI doesn't publish a full list of the search providers ChatGPT uses, so don't pick one favourite listing. Consistency across all the major ones is the point. For Bing, Microsoft's own page on adding and managing your business listing is the starting place. For Apple, note that Apple can edit your place card itself after customer reports, changing the name, open or closed status or hours, and emails your administrators when it does; its guide says a disputed name change must be contested within five business days. Keep the notification emails going to someone who reads them.
A plain facts block for your contact page
The single most useful fix is a short block of facts in plain text on your contact or about page, written the way a customer would ask. This is the sign maker's, filled in (the name and address are placeholders):
[Business name], independent sign makers since [year]. Workshop: [full address]. We moved here from [old estate name] in [year]; we no longer use the old unit.
Opening hours: Monday to Friday 8am to 5pm. Saturday 8am to 1pm. Closed Sunday. Visits by appointment are best, so we can have samples ready.
We make: shop fascias, projecting signs, window graphics, van livery and LED neon-effect signs. We don't make glass neon.
Prices: every sign is quoted individually after a free site visit or photo survey. Fitting is quoted separately.
Note the lines that state what isn't true any more ("we no longer use the old unit", "we don't make glass neon"). Assistants that search will find and repeat those corrections, which a page that simply omits the old facts can't do.
Don't expect special files to shortcut this. Google says its AI Overviews and AI Mode need no special optimisation beyond normal SEO and don't use llms.txt files or special markup. Plain, consistent facts on real pages are what every assistant reads. The broader side of this, being recommended at all, is covered in how to get your business recommended by ChatGPT and AI search.
The sign maker's month, from wrong hours to right answers
Here is how the fixes played out, with illustrative timings.
Week 1: own site and main listings
The sign maker rewrote its contact page with hours in plain text ("Monday to Friday 8am to 5pm; Saturday 8am to 1pm; closed Sunday"), added a short "What we make" list that said "LED neon-effect signs (we don't make glass neon)", and deleted the old price-list PDF, redirecting its URL to the quote page. Its web developer confirmed robots.txt didn't block OAI-SearchBot. Google Business Profile, Bing Places and Apple Business were all corrected the same afternoon. Total: about four hours.
Week 2: the long tail of directories
Of the 14 listings with the old address, 9 could be edited directly, 3 needed an emailed request, and 2 belonged to directories that no longer responded. Those two stayed wrong, which is normal; the aim is for correct listings to outnumber and outrank the stale ones.
Weeks 3 and 4: recheck
Asked the same questions in Temporary Chats, ChatGPT with search now gave the correct Saturday hours and address in 3 of 3 tries, citing the sign maker's own contact page and its Google listing. Perplexity dropped the $99 figure once the PDF was gone. The neon claim persisted in answers given without search, which is the training-data problem; the "we don't make glass neon" line on the site means any searched answer now corrects it. The Saturday afternoon visitors stopped within the month.
The quick sum on whether it was worth it: before the fix, the workshop was fielding two or three wasted Saturday visits a week, each costing a staff member 10 to 15 minutes and a customer a wasted trip. Around six hours of fixing ended a problem that was costing more than that every month, and some of those customers had simply gone elsewhere.
Other businesses, other wrong answers
- A print shop mistaken for a franchise. ChatGPT gave an independent print shop the opening hours and online-ordering details of a national franchise with a similar name. The fix was a clear "independent, family-run" line on its about page, its full legal name and trading name on every listing, and consistent categories. Thin listings make mix-ups likelier.
- A clothing shop's returns policy. ChatGPT told a shopper returns were free; they cost $4.95 unless the item is faulty. The source was an old FAQ page from a promotion. When a customer quoted the AI answer, the shop honoured it once and updated the FAQ. If you run your own AI chat on the site, the tutorial on stopping an AI chatbot giving customers wrong answers covers the other half of the problem.
- A software reseller's old partner status. AI answers described a reseller with a vendor partnership designation that the vendor had since retired. It updated its site to describe what it actually does and removed the old badge images, which were the only place the old wording survived.
- An events company that doesn't cater. Assistants said it offered in-house catering, because many similar companies do and its services page never said otherwise. Adding "We work with your chosen caterer; we don't cater ourselves" fixed searched answers. Sometimes the missing fact is the problem.
When a customer turns up with the wrong information, the conversation matters as much as the fix. The tutorial on what to do when AI gets something wrong with a customer has wording for those moments.
Feedback buttons, privacy requests and what they can't do
Every assistant has a way to flag a bad answer. In ChatGPT, give the response a thumbs-down and say what's wrong; Google's AI Overviews and the other assistants have similar feedback options. Do it, because it's quick, but don't expect it to fix the answer for everyone; treat it as a report, not a correction.
OpenAI's privacy policy does offer a route for people who find inaccurate personal information about themselves in ChatGPT output: a correction or removal request through its privacy request portal. OpenAI says it may not be able to correct the inaccuracy in every instance, in which case you can ask for your personal information to be removed from output instead. That route is about information relating to a person, such as a sole trader named in a wrong answer, not a general way to correct business facts.
When a wrong answer could damage your business
Some wrong answers are more than inconvenient: "this company has closed down", "was fined for unsafe work", "uses nickel in its silver". An illustrative case: a jewellery seller found an assistant stating that its "sterling silver" contained nickel, which matters to buyers with allergies. Customers started asking about it in messages.
- Record it thoroughly: screenshots, exact questions, dates, tools, sources shown.
- Find and fix the source if there is one. In the jewellery case, a reseller site had copied an old product description for a different, plated product.
- State the correct fact clearly on your own site, in plain words: "Our sterling silver is 92.5% silver; we don't use nickel in any of our metals."
- Report the answer through the assistant's feedback option.
- Reply to customers calmly, with the fact and where to find it. A short template helps: "Thanks for checking. An AI tool has this wrong: [correct fact]. You'll find it on our [page]. Happy to answer anything else."
- Get legal advice if the claim is causing real harm and persists. Don't threaten anyone publicly.
A monthly ten-question check across AI assistants
Once the fixes are in, a monthly check keeps them honest. Ask the same ten questions in ChatGPT (search on, Temporary Chat), Gemini, Copilot and Perplexity, and note anything wrong. It takes about 20 minutes.
- What are [business]'s opening hours, including weekends?
- Where is [business]?
- What does [business] make or sell?
- What doesn't it do? (Ask about your most common wrong assumption.)
- How much does [main product or service] cost at [business]?
- How do I contact [business]?
- What is [business]'s returns, cancellation or guarantee policy?
- Who owns or runs [business]?
- What do customers say about [business]?
- Who are [business]'s competitors?
Question 10 is there because it shows which businesses the assistants confuse you with. If the answers are right three months running, drop to quarterly. If you also want to know whether AI search is sending you customers, the tutorial on tracking whether AI search is sending you customers covers measurement.
Wrong AI answers: follow-up questions
Can I contact OpenAI to change what ChatGPT says about my business?
There's no general service for correcting business facts. You can give feedback on a specific answer, and OpenAI's privacy policy offers a route for individuals to request correction or removal of inaccurate personal information, though OpenAI says it may not be able to correct every instance. For most businesses, fixing the sources ChatGPT finds when it searches is the practical route.
How long does a fix take to show up in ChatGPT?
Answers that come from a web search can change within days or weeks of the source pages being updated and recrawled. Answers from what the model learned in training change only when newer models are trained, which can take months or longer. That's why the correct version needs to be easy to find, so searched answers win.
Will adding structured data or an llms.txt file fix AI answers?
Don't rely on them. Google says its AI Overviews and AI Mode need no special optimisation beyond normal SEO and don't use llms.txt files or special markup. Clear, consistent facts on your own pages and listings do more than any special file.
Should I block ChatGPT from my website if it keeps getting things wrong?
Usually not. Blocking OpenAI's search crawler, OAI-SearchBot, keeps your site out of ChatGPT's search answers, which means it can only rely on other sources about you, including outdated ones. OpenAI's separate GPTBot crawler is for training, and blocking that doesn't affect search answers.
Do other assistants need the same fixes?
Mostly yes. Gemini, Copilot and Perplexity also draw on web pages and business listings, so correcting your site, Google Business Profile, Bing Places and Apple Business helps all of them. Check each one in your monthly test, because they don't all update at the same speed.
