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.
