  "question": "Does raw domain count matter more than repeat-cited authority?",
  "directAnswer": "No. The citation graph is broad, but models still repeat a relatively small set of trusted URLs and domains. Breadth matters for opportunity, while repeat-cited authority is what actually converts into recurring mentions.",
  "answerSummary": "Authority hubs, benchmark pages, and tightly extractable answers often outperform generic breadth alone.",

  "whyItMatters": "Operators must prioritize building high-trust reference pages rather than spreading content across many low-authority domains, as AI models heavily favor a concentrated set of trusted sources for recurring citations.",
