A gatekeeper source is a website that AI answers rely on again and again for a category, such as a review site, a comparison article, a forum thread or an industry publication. When an AI builds its answer from these sources, the brands those sources feature are the brands the AI recommends.
A gatekeeper source map lists these sources and shows which of them include your brand, which include competitors, and which ignore you.
If the pages AI trusts do not mention you, improving your own website alone will not change AI answers quickly. Knowing the gatekeepers tells you where to earn coverage, which listings to fix and which publications to approach.
