How to add an llms.txt to a Hugo site (2026 guide)

Updated · July 10, 2026Joffrey

What is GEO?

Hugo doesn't serve an llms.txt file by default. Here's how to add one — plus Q&A schema.org markup — so AI answer engines can read your Hugo site and cite it in their answers. The steps are concrete and take a few minutes.

Why add an llms.txt on Hugo?

AI answer engines (ChatGPT, Perplexity, Gemini, Claude) cite only a handful of sources per question, and they favor pages they can read cleanly. An llms.txt hands them a clear, structured version of your site; Q&A schema.org markup makes your answers quotable word for word. Without it, even ranking well on Google, your Hugo site is unlikely to appear in an AI answer — not for lack of quality, but because nothing is machine-readable.

Add the llms.txt and Q&A markup on Hugo

  1. Q&A markup: add it into the <head>, via layouts/partials/head.html (or your base template baseof.html).
  2. llms.txt, llms-full.txt and robots.txt: place them in the static/ folder (not content/) — Hugo copies them to the root (static/llms.txt/llms.txt).
  3. If enableRobotsTXT = true in your config, Hugo generates robots.txt itself: then merge our lines into the template rather than adding a static file (otherwise a conflict).

Verify it's live

Open your-site.com/llms.txt in a browser: you should see the file in plain text. Then test a page in Google's Rich Results Test to confirm the Q&A JSON-LD is detected. Until both checks pass, AI engines see nothing.
