A client called me last month in a mild panic: ChatGPT was telling people her clinic still operated at an address she had left two years earlier, and Google's AI Overview was quoting hours from before the pandemic. Nobody had touched her website's contact page in years, so technically it wasn't "wrong" anywhere obvious. This is the problem almost nobody prepared for. Learning how to correct outdated business information in AI has become a real part of my job, because the answer engines your customers now trust are confidently repeating facts that stopped being true a long time ago.
Here's the uncomfortable truth. Traditional SEO taught us to fix a page and wait for Google to recrawl it. AI systems are messier. They blend stale training data, cached snapshots, and third-party sources that themselves lag behind reality. When a large language model says your restaurant closes at 9pm or that you still sell a product you discontinued, it is usually not making things up. It is faithfully reporting an old fact from a source it trusts.
In this guide I'll walk through exactly how I diagnose and fix outdated business information in AI answers for my clients, in the order I actually do it, and how long you should realistically expect corrections to take.
Why AI Repeats Outdated Information About Your Business
Before you can fix anything, it helps to understand where the wrong answer is coming from. AI assistants don't have a single "database of your business" they can edit. They assemble an answer at runtime from a few different layers, and any one of them can be out of date.
The Four Places Stale Facts Hide
- Training data: The model learned patterns from a snapshot of the web that may be a year or more old, so it "remembers" your former address or old branding.
- Retrieved sources: When a tool like Perplexity or Google's AI Mode cites live pages, it can grab an outdated directory listing, an old press release, or a competitor's blog.
- Your own website: Orphaned pages, old location pages, and cached PDFs often still carry the numbers you meant to retire.
- Third-party profiles: Yelp, industry directories, Wikidata, and data aggregators feed both Google and AI systems, and they update slowly.
The practical takeaway is that you have to fix the underlying sources, not the AI output itself. You can't log into ChatGPT and edit what it says. But you can change what it reads the next time it looks you up, and you can make the correct version so consistent and authoritative that it wins.
How To Audit What AI Actually Says About You
You'd be surprised how many business owners are furious about a wrong answer they've never actually seen with their own eyes. Start with a calm, structured audit so you know precisely what needs correcting and where each error traces back to.
Interrogate the major assistants
Ask ChatGPT, Gemini, Perplexity, and Copilot the same set of plain questions a customer would: "What is [business]'s address?", "What are their hours?", "What does [business] sell?" Save the answers verbatim.
Capture the citations
On the tools that show sources, note every URL they cite. That list is your fix list. If Perplexity is quoting a 2023 directory page, you now know the exact page to correct.
Cross-check Google Search and Maps
Because AI Overviews and knowledge panels lean heavily on Google's index, search your brand and read the knowledge panel, the Business Profile, and the top results for stale details.
Build a correction sheet
List each wrong fact, the correct value, and every source that repeats the error. This single document keeps a messy cleanup organized and lets you measure progress.
Start With Your Google Business Profile
If you fix only one thing, fix this. Your Google Business Profile is the closest thing to a source of truth that both Google and AI systems treat as authoritative for a local business. It's also the fastest to update. In my client work, correcting the profile often cleans up half the errors within a couple of weeks because so many downstream systems pull from it.
Sign in, verify the listing is claimed, and correct the name, address, phone, hours, categories, and any special hours. Google documents the full editing process in its Business Profile Help center, and it's worth following their steps precisely so edits aren't reverted. If your business moved, closed a location, or rebranded, handle those explicitly rather than just editing text, and get help from a proper local SEO and GMB service if the listing has duplicates or ownership issues.
Google Business Profile Correction Checklist
- Name & address: Match them exactly to your legal, current details, character for character.
- Hours: Set regular and special hours, and remove any temporary COVID-era notes still lingering.
- Closed or moved locations: Mark permanently closed or moved so old pins stop misleading people.
- Products & services: Delete discontinued items; AI loves to resurface things you no longer offer.
- Photos & descriptions: Replace old signage photos and rewrite the description with current facts.
Make Your Website the Cleanest Source of Truth
AI systems and Google both cross-reference your own site to confirm what they read elsewhere. If your website contradicts itself, you give them permission to trust an outdated third party instead. I treat the website as the anchor that every other source should agree with.
Update your contact page, footer, location pages, and any "about" content so the name, address, phone, and hours are identical everywhere. Then hunt for the sneaky stuff: old landing pages ranking for a former product, cached PDFs, and duplicate location pages from a previous site build. A quick technical crawl usually surfaces them, and this is where a focused technical SEO cleanup pays off. If you've never audited whether your site is even readable to AI crawlers, my guide on how to get your business to show up in ChatGPT covers the crawlability basics that apply here too.
Clean Up the Third-Party Sources AI Trusts
This is the slow, unglamorous work that actually moves the needle. AI systems corroborate facts across the web, so a single outdated directory can keep resurrecting an error you already fixed on your own site. Work down your correction sheet source by source.
Where To Fix Outdated Facts (In Priority Order)
| Source | Why AI trusts it | How to correct it |
|---|---|---|
| Google Business Profile | Primary local source for Google & AI Overviews | Edit directly; verify ownership |
| Your website + schema | Confirms and anchors every other claim | Update copy; add LocalBusiness markup |
| Wikidata / Wikipedia | Feeds knowledge graphs and LLM training | Edit with reliable citations |
| Data aggregators & directories | Syndicate NAP to dozens of sites | Claim listings; push corrected NAP |
| Review sites & social | Cited for reputation and current details | Update profiles; correct pinned info |
Consistency across these profiles is the whole game. When your name, address, and phone match everywhere, AI systems have no conflicting version to fall back on. That same discipline underpins my broader advice in improving your brand's AI reputation, and it's a core part of any serious complete SEO engagement I run.
Structured Data, llms.txt, and Entity Signals
Correcting text is necessary but not always sufficient. You also want to hand machines the facts in a format they can't misread. Structured data does exactly that, and it's one of the highest-leverage moves for making the correct version stick.
Machine-Readable Signals Worth Adding
- LocalBusiness schema: Mark up name, address, phone, hours, and geo using Schema.org's LocalBusiness type so there's zero ambiguity.
- Organization + sameAs: Link your official profiles so systems know which directory entries are really you.
- FAQ and about content: State current facts plainly in prose that answer engines can quote.
- llms.txt: A concise, current summary of your business gives AI crawlers an authoritative, easy-to-parse reference.
- Dates: Add or update published and modified dates so freshness signals favor your corrected pages.
The pages AI platforms lean on aren't random. If you want to understand what earns citations in the first place, I broke down the sources AI platforms use to evaluate businesses in a separate post, and structured, consistent data runs through all of them.
How Long Until AI Actually Updates Your Information?
This is the question every client asks, and honestly, the answer requires patience. There's no "submit correction" button that instantly rewrites what a model says. Different systems refresh on very different clocks.
Live-retrieval tools like Perplexity and Google's AI Overviews can reflect a corrected source within days to a few weeks once the underlying page is recrawled. Google Business Profile edits often propagate the fastest. The trained "memory" of a model is the slowest part, sometimes only shifting when a new model version is released. In my experience, most visible errors clear within four to eight weeks if you've fixed the real sources, while a stubborn training-data artifact can linger longer until the surrounding web overwhelmingly reflects the new truth.
Monitor So the Errors Don't Come Back
Fixing outdated business information in AI once isn't the finish line. Sources drift, aggregators re-import old data, and new AI features surface old facts again. I set every client up with a lightweight monitoring rhythm so nothing quietly rots.
A Simple Monitoring Routine
- Monthly spot checks: Re-run your core questions across the major assistants and log the answers.
- Search Console review: Watch impressions and queries to catch odd branding or old terms resurfacing.
- Profile alerts: Turn on notifications for Google Business Profile suggested edits so you can reject bad ones.
- Citation sweeps: Quarterly, recheck top directories and aggregators for reverted or duplicated data.
- Version watching: When a major model updates, re-audit, since fresh training can reintroduce old facts.
If you don't have time to run this yourself, it's exactly the kind of ongoing work I handle as an SEO consultant many clients call the best SEO expert they've worked with, precisely because I catch these drifts before customers do.
Frequently Asked Questions
Can I directly edit what ChatGPT says about my business?
No. You can't edit a model's output. What you can do is correct the sources it reads and remembers, keep them consistent, and wait for the next crawl or model refresh. Over time the correct version wins because it's the one repeated everywhere authoritative.
Why does AI still show my old address after I fixed my website?
Because your website is only one source. AI systems corroborate facts across directories, review sites, Wikidata, and their own training data. If any of those still carry the old address, the model may trust them. Fix every source on your correction sheet, not just your site.
Does structured data help correct AI answers?
Yes. Clean LocalBusiness and Organization schema gives machines unambiguous facts and helps them tie your official profiles together. It won't override a model's memory overnight, but it strongly reinforces the correct version during live retrieval.
How often should I check what AI says about my business?
Monthly spot checks are plenty for most businesses, with a deeper quarterly citation sweep. Re-audit any time you move, rebrand, change hours, or a major AI model releases a new version.
Conclusion: Own Your Facts Before AI Decides Them For You
The businesses that stay accurate in AI answers aren't lucky, they're deliberate. They treat their Google Business Profile, website, schema, and third-party listings as one connected system that all tells the same story. When you make the correct version of your business the most consistent and authoritative version on the web, correcting outdated business information in AI stops being a fire drill and becomes routine maintenance.
Start with the audit, fix the sources in priority order, add the machine-readable signals, and then watch. The web moves slowly, but it does move, and the truth you keep repeating is the one these systems eventually settle on. If you'd rather have an expert run the whole cleanup and keep it clean, that's exactly what I do every day.
