A growing share of commercial research now happens inside conversational assistants and AI summaries rather than in a list of ten blue links. The person asking which agency handles a particular problem in a particular market may never see a results page at all. They see a synthesized answer naming two or three companies, and everyone else is invisible regardless of where they rank.
This changes what optimization means. Traditional search rewards the page that best matches a query. Answer engines reward sources that state facts clearly, in structured and unambiguous language, and that are corroborated elsewhere. A page can rank well and still never be cited, because its key information is implied by design rather than stated plainly.
This checker looks for the characteristics that make a site usable as a source: whether core facts about the business are stated explicitly, whether structured data describes the entity properly, whether content answers questions directly, and whether the business is described consistently across the wider web. These are the inputs available to a model assembling an answer about you.
