- An LLM audit has 4 layers: crawlability, extractability, entity clarity, citation baseline.
- Most failures are extractability — LLMs read the page but cannot pull a clean answer.
- You need a baseline mention share before you fix anything.
- Optymia's free audit exports the full 60-minute report as a PDF.
The 4 layers of an LLM audit
- Crawlability: OAI-SearchBot, PerplexityBot, GPTBot, Google-Extended allowed in robots.txt.
- Extractability: question-formatted H2s, short paragraphs, FAQPage schema, visible last-updated date.
- Entity clarity: Organization schema, sameAs to Wikipedia/Wikidata, consistent brand NAP.
- Citation baseline: mention share across a 25-prompt panel in ChatGPT, Perplexity, Gemini, Claude.

Run this on your top 10 pages. Every 'no' is a fix.
- H1 is phrased as the exact question buyers ask?
- 40–60 word direct answer immediately under H1?
- 3–7 H2s, each phrased as a follow-up question?
- FAQ block with 4–8 questions plus FAQPage JSON-LD?
- Visible Last updated date within 90 days?
- Author byline with credentials?
- At least one proprietary statistic on the page?
- Two authoritative external citations?
