Ask ChatGPT or Perplexity for your pricing and the answer may be confidently wrong, pulled from a page you stopped maintaining two years ago. Inaccurate brand information in AI answers is rarely invented by the model; it is usually faithful retrieval of a bad source. This guide shows how to find each wrong claim, trace it to the page causing it, and correct it where AI engines actually read.
Quick answer
Most wrong answers come from retrieval of outdated or incorrect web pages, not from invention. Engines pull live pages, including your own site and third-party articles, and repeat what those pages say. Check the cited source first.

Why wrong claims about your brand are a revenue problem
Buyers now ask AI engines before they open a search results page. Forrester's State of Business Buying 2026, as summarised by AuthorityTech, describes generative AI searches as a starting point for B2B buyers, with a typical purchase involving 13 internal stakeholders and nine external influencers. A wrong price or outdated feature in that first answer can end a shortlist before a human seller is involved. Gartner's figure, cited by Thrive Agency, puts the cost of stale brand information at at least $12.9 million a year for organisations. Treat each error as a defect with a cause, not as background noise.
inaccurate brand information in ai answers — by the numbers
What counts as an incorrect claim?
An incorrect claim is any statement about your brand that is false, outdated, incomplete or misattributed. According to Screpy, a claim can be wrong even when the engine cites a real source. The source itself may be stale, or the claim may be attached to the wrong entity. Omissions count as well. For example, an engine that lists your competitors but never mentions your brand has produced an incorrect answer. Before you act, sort every finding into one of five buckets: wrong, stale, unsupported, misattributed, or omitted. Each bucket requires a different fix.
- Wrong: the claim is false
- Stale: the claim was once true but is outdated
- Unsupported: the claim has no credible source
- Misattributed: the claim is attached to the wrong entity
- Omitted: the brand is missing from an answer where it belongs
Why AI engines get brand facts wrong
Most errors come from one of three layers. According to DeepSmith, AI brand answers are assembled from training data snapshots, live retrieval at query time, and entity records such as Google's Knowledge Graph, Wikidata, Wikipedia and Bing's entity index. Retrieval is usually the culprit. According to Profound's FactCheck study of more than 158,000 brand claims, AI engines rarely fabricate brand facts. Inaccuracies overwhelmingly come from real retrieved pages that are outdated or wrong. Entity confusion is the second common cause. A model may blend your brand with a similarly named competitor, and this is hard to spot without claim-level review.
Where do errors concentrate?
Pricing and billing claims are the most error-prone category in AI answers about a brand. According to Profound's FactCheck study, pricing and billing claims were 12% of evaluated claims but 24% of inaccurate claims. About 35% of earned-media inaccuracies involved pricing. Product specifications, availability and leadership details follow. Teams should verify these fields first, checking the live pricing page and current product documentation, rather than auditing the whole brand at once. Inaccuracy rates also vary by engine. According to the same study, rates run roughly 4.3% to 6.8% per answer engine, and only about 11% of inaccurate claims overlap between models. Therefore, each engine must be tested separately. Teams can use Semrush's AI Visibility Toolkit, whose prompt database contains 213 million prompts, to structure that testing across engines.
How do you find and trace wrong answers?
Finding and tracing wrong answers means testing a fixed prompt set and tracing each error to its cited source. Build a fixed set of 30 to 50 questions that buyers really ask. Include category queries, pricing questions, comparison prompts and "is X good for Y" checks. Run the set across ChatGPT, Perplexity, Gemini and Google AI Overviews. Log each claim with its engine, date and cited URL. According to Semrush, AI tools do not return the same answers, and responses shift as models update, so a one-time search cannot surface patterns. Repeat the run monthly. Tracing is the decisive step. For each wrong claim, open the cited source, confirm the claim appears there, and record that page as the root cause. If no citation exists, the error came from training data or an entity record, so the fix moves to those layers.
How do you correct the sources and re-test?
Correct each root-cause page directly: your own site, structured data, Google Business Profile, directory listings and any third-party article that repeats the error. Thrive Agency stresses that LLMs have no edit button, so fixes belong at the source. Feedback buttons do not count as corrections; DeepSmith describes them as reports, and monitoring tools identify errors without fixing them. Propagation is not instant, so re-run the same prompt set after each change and compare results against your log. Some claims will persist after the source is fixed, because retrieval indexes update on their own schedule. Note that limit in your reporting rather than promising a date. Tools such as Fastlook's Brand Memory and Citation Analytics help keep the source of truth and the test log in one place, but the correction work itself stays with your team.

Frequently asked questions
Why does ChatGPT give wrong information about my brand?
Most wrong answers come from retrieval of outdated or incorrect web pages, not from invention. Engines pull live pages, including your own site and third-party articles, and repeat what those pages say. Check the cited source first. However, if it is stale, correct that source and re-test.
How do I find out what AI says about my brand?
Find out what AI says about your brand by running a fixed set of buyer prompts. Run them across ChatGPT, Perplexity, Gemini and Google AI Overviews. Log each claim, its engine, its date and any cited URL. Repeat the run monthly to catch changes.
Can I edit what AI engines say about my company?
No, you cannot edit AI engines directly. According to Thrive Agency, LLMs such as ChatGPT, Gemini, Claude and Perplexity have no edit button. Outdated information must instead be corrected at its sources: your website, Google Business Profile, local listings and third-party directories. According to DeepSmith, feedback buttons on engines are reports rather than corrections.
Which brand facts are most often wrong in AI answers?
Pricing and billing claims are the most error-prone brand facts in AI answers. According to Profound's FactCheck study, pricing and billing were 12% of evaluated claims but 24% of inaccurate ones. Therefore, verify pricing, product specifications, availability and leadership details first against live pages.
Why do AI answers mix my brand up with a competitor?
Entity confusion happens when a model blends records for brands with similar names or overlapping categories. It is hard to detect without claim-level review. Strengthen your entity records, including Wikidata, Wikipedia and Knowledge Graph entries. Specifically, make your own pages state the brand name and category explicitly.
How long does it take for a correction to show up in AI answers?
There is no fixed timeline for corrections. Retrieval indexes and training snapshots update on their own schedules, so a corrected page may take weeks to surface. Some errors persist even after the source is fixed. According to Semrush, AI answers shift as models update. Re-run your prompt set after each change and record the results rather than assuming a date.
Which sources should I correct first?
Start with the page each wrong claim cites, since that page is the root cause. Then fix your own website and structured data, Google Business Profile, directory listings and any third-party article repeating the error. Prioritize claims buyers see most often, such as pricing. According to Profound's FactCheck study, pricing claims were 24% of inaccurate claims despite being 12% of evaluated claims.
Does AI misinformation about my brand affect leads?
Yes, incorrect AI answers can affect leads. According to LSEO, wrong answers spread at the moment a buyer asks a high-intent question. They can affect branded search, lead quality, conversion rates and investor confidence. Tracking wrong claims alongside citations shows where lost consideration is happening.
