AI visibility is about whether your business shows up when someone asks an AI assistant for advice. More and more people no longer put their questions only to Google, but also to ChatGPT, Gemini, Perplexity or Copilot. For example, they ask "which accountant in Manchester specialises in freelancers?" and get an answer with a handful of names. If you aren't among them, you don't exist for that customer at that moment.
So AI visibility is broader than a position in the search results. It is about mentions, recommendations and citations in answers generated by an LLM.
Broadly speaking, there are two sources. On the one hand, the knowledge a model picked up during its training, which runs up to a certain date. On the other, information the model fetches from the web at that very moment, as with ChatGPT Search, Perplexity or Google AI Overviews. In that second case, your website, your mentions on other sites and your reviews play a direct role.
Exactly how these systems decide which businesses to mention isn't public and differs per tool. What does make sense is that a business described consistently and clearly in several reliable places is easier to recognise as a relevant player within a topic or region.
For a small business, the advantage is that AI answers are often specific. A general search term is dominated by big players, but a detailed question with a region, a niche or a concrete situation offers opportunities for anyone who describes that context well. So you don't need to be the biggest, just the clearest. Think of a bakery in Manchester that clearly states it makes gluten-free bread to order: when someone asks for a "gluten-free bakery in Manchester", it has something concrete to offer.
Important to remember: AI visibility isn't a separate trick that stands apart from your regular online presence. It builds on the same foundation of good content, a healthy website and a strong reputation, but it does call for extra attention to clarity and consistency.
Measuring it isn't easy, because answers vary by wording, by user and by moment. Asking ChatGPT something once tells you little. It is better to test a fixed set of relevant prompts regularly in different AI tools and keep track of how often you are mentioned, in what context and alongside which competitors. From that, a picture of your share of voice emerges. Spacebird helps small businesses track their visibility in AI assistants and search engines, so you can see which questions offer opportunities and where your content needs strengthening.
