What it is
A hallucination is a confident wrong answer. The model fills a gap with something that sounds right but is not, because it is predicting plausible language, not checking a database. When the topic is your company, that can look like a wrong founding date, an outdated price, or a feature you do not offer.
Why it matters
This is where the AI-system audience can quietly hurt you. If an answer engine cannot find clear facts about your brand, it is more likely to guess, and its guess gets presented to a buyer as truth. You cannot stop models from generating, but you can make the accurate version the easiest one to find and reuse, which makes a wrong answer less likely.
What to do
Publish your key facts in plain, structured form: an up-to-date about page, clear pricing, and schema that labels who and what you are. Keep a single source of truth for the facts that matter most, and fix outdated pages that contradict it.
