Hallucination — VibecodeAEO Glossary

Hallucinations about your brand are reputation risks. They are also AEO opportunities: when ChatGPT consistently misstates your pricing or feature set, the fix is to publish authoritative, well-structured content that overrides the hallucination in the next model update.

VibecodeAEO scans for hallucinations weekly and surfaces the exact prompts where your brand is being misrepresented — with the suggested content fix.

Real-world example

ChatGPT tells a prospect that a security SaaS has 'SOC 2 Type I certification' when they actually have Type II — a material difference. The company publishes a detailed compliance page with FAQPage schema, correct schema data, and a press release. The hallucination disappears from ChatGPT answers in the next model refresh.

Frequently asked questions

How do I fix an AI hallucination about my brand?+

Publish authoritative, factual content that directly contradicts the hallucination. Use FAQPage schema on the corrected content. Update your llms.txt to link to this correction page. Earn links to the correction from credible sources. For retrieval-based engines, corrections appear within days; for training-based engines, allow 3-9 months for the next model update.

How common are AI hallucinations about brands?+

Very common — VibecodeAEO finds material factual errors in 60-70% of brand audits. The most common: wrong pricing, features attributed to competitors, outdated team information, and incorrect category positioning. Brands with weak entity signals (no schema, no Wikidata) hallucinate at much higher rates.
