AI hallucination

An AI hallucination is a convincingly worded but false or fabricated statement by an AI system. Language models compute plausible phrasings — where a reliable source is missing, they guess. Risky for businesses: invented opening hours or services look deceptively real.

Hallucinations stem from how large language models work: they compute which phrasing is most likely — not which one is documented. Where reliable information on a question is missing, the model fills the gap with something plausible. The result sounds confident but may be entirely made up: a wrong phone number, a closing day that never existed, a service you do not offer.

The most effective remedy from a business's point of view: give the AI reliable material. An up-to-date website as the central source of truth, consistent contact details everywhere and structured data that labels facts unambiguously. Modern AI systems consult real sources before answering — a business that presents itself clearly and machine-readably there gets reported correctly instead of guessed at.

For your business that means checking regularly what assistants say about you — opening hours, prices, services. If wrong details appear, the cause is almost always an outdated or contradictory source. The fix happens not inside the AI but at the source: bring your website, Google profile and directories to the same, current state.

Frequently asked questions.

How do I keep opening hours and contact details up to date everywhere?

The core principle: one source instead of many copies. If opening hours, address and phone number are maintained in one central place, and the website, structured data and machine-readable formats automatically serve the same state, nothing can drift apart. That is exactly what a website built as a single source of truth delivers: change it once, current everywhere.

Externally, the effort stays manageable: above all, keep your Google Business Profile and the most important directories up to date — with exactly the same details as on your website. For seasonal hours, a fixed routine helps, say at the start and end of the season. The background: contradictory details are the most common reason AI assistants tell people wrong things about a business.

Why does an AI recommend me with the wrong number or opening hours?

Because AI assistants don't invent their facts — they pull them from map and directory data. If your details are inconsistent or outdated there — an old number, a wrong opening hour — the AI picks up exactly that and states it confidently as an answer.

Directories also often copy from one another, so a single error spreads across several platforms. For your business, that means a small inconsistency in one place can end up as a wrong answer in several AI responses.

How do I find out whether an AI gives wrong information about my business?

Regularly ask the major AI assistants about your own business — services, opening hours, prices, and how you compare to competitors — and check the answers for accuracy. Without this check, wrong information often only surfaces when customers arrive with false expectations or never get in touch at all.
