AI Hallucination

When an AI model generates information that sounds plausible but is factually incorrect or unsupported by its sources.

Why it happens

A language model generates the most statistically likely next words, not necessarily verified facts. When it lacks solid grounding on a topic — including about a specific brand — it can fill gaps with confident-sounding but inaccurate detail.

What it means for brand visibility

Sparse or inconsistent information about a brand across the web increases the chance a model fills the gap incorrectly. Clear, consistent, factual content in multiple independent sources reduces the room for a model to guess wrong.
