Some attach a URL. Some name a firm and attach nothing. Some attach a competitor because that page states the fact in one clean paragraph and yours hides it in a chart. This page owns eligibility: the sentence, the source that can carry it, and the sample that shows whether attribution happened. Search intent on that source still has to match a question a buyer would ask. A slogan is not a claim.
Brand mention work finds names with no source. LLM brand visibility checks the string models speak. Knowledge Graph work starts from a public panel. Digital PR earns coverage you do not have yet. Work this page if you can name a sentence and a page that should prove it. A newsroom, a panel box, or ChatGPT-style rewriting of the answer belongs elsewhere.
We will not promise Perplexity will cite you. We will not treat one assistant UI as the whole program. We will not sell a citation quota. If the claim is true only in a sales deck, we name that first. If two pages on your site contradict the number, we name that second. Eligibility is the job. A purchased footnote is not.
