How to add an llms.txt to WordPress (2026 guide)
Updated · July 10, 2026 — Joffrey
What is GEO?→WordPress 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 WordPress site and cite it in their answers. The steps are concrete and take a few minutes.
Why add an llms.txt on WordPress?
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 WordPress 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 WordPress
- Upload
llms.txt,llms-full.txtandrobots.txtto your site root (same level aswp-config.php), via FTP or your host's File Manager. - Paste the Q&A markup into your
<head>with a header plugin (e.g. WPCode or “Insert Headers and Footers”). - If an SEO plugin already generates a virtual
robots.txt, paste our lines into that plugin's robots editor instead of a file.
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.
