FAQ Optimization for Claude

FAQ content earns Claude citations when each question-answer pair works as a standalone retrievable unit: a heading phrased exactly the way users prompt, followed by a 40-80 word answer that survives being quoted alone. Claude's retrieval chunks your page into passages and matches them against the user's question, so FAQ optimization is really passage engineering, applied systematically.

Why does the 40-80 word answer band matter?

Retrieval-augmented systems like Claude's web search embed and rank passages, not pages. An answer under 40 words often lacks the evidence to be quoted as authoritative; one over 80 words gets truncated mid-thought and loses coherence. Write the complete answer, entity named, fact included, inside that band, then expand below it for human readers if needed. The first sentence should resolve the question outright: "Yes, Claude's fetchers respect robots.txt; all three Anthropic user agents check it before requesting a page" beats three sentences of wind-up.

Matching headings to real prompt phrasing

Claude users ask full natural-language questions, so your H2s and H3s should mirror them verbatim: "Can I export my data to CSV?" not "Data portability." Mine the phrasing from support tickets, sales-call transcripts, People Also Ask boxes, and your site search logs. Prompt research shortens this step by showing the actual question formulations users put to AI engines in your category, the gap between how marketers label things and how buyers ask about them is consistently wide.

FAQ patterns: what works and what fails

The accordion row deserves emphasis: accordions are fine if the full text ships in the initial HTML and CSS handles the collapse. If your framework mounts answer text client-side, Claude-User sees empty containers.

FAQPage schema, done correctly

Add FAQPage JSON-LD listing each Question with its acceptedAnswer, keeping schema text identical to visible text. Google restricted FAQ rich results to government and health sites in August 2023, but that was a SERP-display decision, the markup remains valid schema.org vocabulary and still gives answer engines a clean map of your Q&A pairs. Claude parses it from raw HTML alongside the visible content; treat it as structural insurance, not magic.

Planning FAQ coverage like a portfolio

Coverage beats depth-per-question. Inventory the questions in your category across four tiers: product-specific ("does X integrate with Slack"), comparative ("is X better than Y for teams"), procedural ("how do I migrate from Y to X"), and category-level ("what is [category] software"). Aim for one strong passage per real question rather than exhaustive essays on a few. Then verify empirically: prompt Claude with your target questions monthly and check whether it quotes you, paraphrases you without citation, or answers from a competitor. The AEO checklist covers the page-level prerequisites, crawler access for all three Anthropic UAs, server-side rendering, clean heading hierarchy, that make every FAQ retrievable in the first place. The compound effect is real: the GEO study by Aggarwal et al. (KDD 2024) measured 30-40% visibility gains from exactly this kind of structured, evidence-dense formatting.
