How ChatGPT, Claude, Perplexity & Gemini choose sources

Each engine retrieves candidates via search partners (Bing, Google, in-house crawlers), re-ranks with an LLM, and cites the top few. Selection weights: relevance, authority, freshness, structural clarity.

What makes content citable by AI

  • A quotable one-sentence answer.
  • Verifiable stats with sources.
  • Neutral, non-marketing tone.
  • Author credentials visible on the page.

Factual density and credibility

AI models prefer paragraphs that pack multiple attributed facts. Vague opinion pieces rarely get cited.

Formatting for AI extraction

Short paragraphs, clear H2 questions, definition lists, and consistent brand naming all boost extraction confidence.

Building brand mentions across authoritative sites

Digital PR, podcasts, industry reports, and Wikipedia mentions bond your brand to its category in model memory.

Monitoring AI citations

Use tools like Otterly, Peec.ai, Profound, or scripted daily query panels to log which URLs get cited across engines.

The future of AI search attribution

Expect richer citation UIs, per-passage credit, and monetized referral programs from AI engines as they mature.
