Answer-engine optimization guide
AEO and GEO with LLMs.txt
LLMs.txt is most useful when it supports a complete answer-engine optimization system, not when it stands alone.
Short answer
For AEO and GEO, use llms.txt as a discovery and citation map: point to canonical pages, explain what each page answers, and link to the full index. Then support it with crawlable pages, FAQ/HowTo schema, direct answer blocks, reference tables, and an XML sitemap.
A practical AEO/GEO checklist
- Keep the target page indexable and internally linked.
- Use one clear H1 and a direct short-answer block near the top.
- Add FAQPage, HowTo, WebApplication, or Article schema only when the content really supports it.
- Include citable reference tables, methodology, and last-reviewed dates where helpful.
- List the canonical URL and a short description in llms.txt or llms-full.txt.
How llms.txt fits with classic SEO
Llms.txt should not be treated as a magic ranking file. It works best when it mirrors a strong technical SEO setup: accurate canonicals, clean robots.txt, XML sitemaps, crawlable pages, and schema that matches visible content. The file is a concise map for assistants; the pages themselves still need to deserve citation.

Frequently asked questions
What is the difference between AEO and GEO?+
AEO, or answer-engine optimization, focuses on being selected as a concise answer. GEO, or generative-engine optimization, focuses on being cited or used by AI-generated answers. In practice they overlap: clear answers, crawlable sources, schema, citations, and strong entity signals help both.
Is llms.txt enough for AI visibility?+
No. It is a helpful discovery layer, but answer engines still need crawlable pages, trusted content, structured data, internal links, and evidence that your site is worth citing. Treat llms.txt as one file in a larger technical SEO and content-quality system.
