Why can't ChatGPT find my products?

Usually because the facts exist on the page for a person to read but not in a form a retrieval system can reach, and the failure sits at one identifiable stage along that path.

Usually because the facts are visible to a person but not reachable by a machine. The failure sits at one point along a path, and identifying which point is the whole diagnosis.

The stages run in order. Human-visible, where a customer can find it by using the interface. Crawlable, where a retrieval system can fetch it. Structured, where it exists as explicit data rather than prose. Channel-ingested, where it is supplied through a feed the destination supports. And integrated for retrieval, where a live service is connected to the system answering the question.

Most teams are at the first stage and assume they are at the third. Store-level stock behind a Find in Store button, compatibility held in a PDF, and a specification table rendered by the CMS but never stored as fields are the three most common examples.

The useful question is not why an AI did not rank you. It is whether the business can answer the question internally, and if so, where the retrieval path stops.
