Definition

Claude rewards depth, attribution, and balance. Marketing-heavy prose is quoted less often than well-cited long-form documentation. Claude is unusually sensitive to fact consistency - contradictions across sources visibly suppress mention rate.

Why it matters

Claude sits in the "Surfaces & platforms" layer of the AI search stack. Teams that handle it well get cited more, recommended more, and earn more of the AI-mediated revenue in their category. Teams that ignore it spend a year wondering why their content investment never moves the needle inside ChatGPT or Perplexity.
