When ChatGPT, Perplexity, or Google's AI Overviews get your brand facts wrong, there is no edit button. AI assistants repeat what they find in their training data and in the pages they retrieve, so the fix is to correct those sources, make your own facts easy to find and consistent everywhere, report the error through each platform's feedback tools, and then re-test the same questions until the answer changes. Expect weeks, not hours.
Key takeaways
AI assistants assemble answers from two places: what the model learned during training and, for many questions, pages it retrieves from the live web. Errors usually come from one of four gaps:
The platforms say as much. Google's help page states that AI Overviews "can and will make mistakes," and OpenAI notes that ChatGPT "can produce incorrect or misleading outputs." You cannot control the model, but you can control much of what it reads.
Record the exact prompt, the platform, the date, and a screenshot of the answer. AI responses change between runs, so ask the same question three to five times, and on more than one platform, before deciding how widespread the problem is.
Also note which sources the answer cites. Perplexity and AI Overviews both link theirs, and those links often point straight to the root cause.
Search for the incorrect detail itself, such as the wrong founding year, an old service, or a price you no longer charge. The pages that still state it are your correction list. Check, in order:
Start with your own website. Publish one canonical facts page that answers the questions people actually ask: what the company does, who it serves, where it operates, how it charges, and who leads it. Write each fact as a plain sentence an AI system can quote without context.
Then remove or update every page that contradicts it. Redirect retired product pages, refresh old pricing, and add an update note to outdated posts rather than leaving them live and unchanged.
Structured data helps machines connect the dots. Organization markup with sameAs entries pointing to your official accounts tells search engines which profiles belong to you, which reduces entity confusion. Confirm that AI crawlers are not blocked from the pages you just fixed. The AEO/GEO checklist walks through crawler permissions, markup, and page structure.
Some third-party profiles carry outsized weight because so many other sites copy from them.

Use the feedback tools, but keep expectations realistic. They send a signal to the platform; they are not a correction request with a guaranteed outcome.
Feedback works best after Steps 3 and 4, once corrected facts are live for any engine that retrieves fresh sources.
If an assistant keeps getting one fact wrong, publish a page that answers that specific question in its first sentence. A page titled with the question people ask, such as how your pricing works or which regions you serve, gives retrieval systems a clear source to quote.
Accurate details tend to surface when they are written down plainly. In one ChatGPT answer about wedding villas in Costa Rica, the assistant described Villa Alberti with specifics that match the property's own published facts, including seven suites and 12,500 square feet. This is the core of Onward's AI search visibility services: write the facts buyers ask about so clearly that an assistant can repeat them without guessing.

Re-run the prompts from Step 1 on a fixed schedule, weekly if possible, on every platform where the error appeared. Record whether the wrong fact still appears, whether the right one replaced it, and which sources are now cited. One clean answer is not proof; a correct answer that holds across several weeks is.
Villa Alberti's program shows that discipline in practice. Onward ran a fixed set of 58 booking-intent questions every week on seven AI platforms, and the villa's overall visibility went from 0.83% at its February baseline to 12.86% by early September. The case study on how a luxury villa won AI search visibility has the full timeline.

There is no fixed timeline. Answers that rely on live web retrieval can change once corrected pages are crawled, while facts the model learned in training may persist until a newer model is released. Correcting your sources helps with both.
Not directly. Feedback tools let you report a problem, and a verified Google knowledge panel owner can suggest changes to that panel, but no platform offers a brand-level edit button for AI answers.
When AI gets your brand facts wrong, fix the record, not the answer. Document the error, trace it to its sources, correct what you control, update the profiles others copy from, report the problem, and track the same prompts until the correct facts hold.
