Prompt coverage
How much of what people actually ask about your kind of business your pages answer. A gap in coverage is a question where an AI system has to use somebody else's site.
Updated August 21, 2026
Coverage is measured by generating the questions a buyer would put to an answer engine about a business like yours, then checking, page by page, whether you answer them. It is the most actionable signal in an audit because every gap names a specific missing page or paragraph. It is also the one most sites are worst at: they describe what they sell, and never answer what people ask before buying it.

- Embedding. A numerical representation of a passage's meaning, used to match a question against your content. It is why a page can be retrieved for a question that uses none of its exact words.
- Answer extraction. The step where the system lifts a specific fact from your page into its answer, like a price, a definition, a step or a yes or no. Content written as clear, self-contained statements extracts cleanly. Vague copy does not.
- Readiness score. A measurement of how prepared your website is to be read, trusted and quoted by AI systems. It is a diagnostic of your site's readiness. It is not a promise of rankings, traffic or actual AI mentions.
