How to add an llms.txt to Ghost (2026 guide)

What is GEO?→Ghost 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 Ghost site and cite it in their answers. The steps are concrete and take a few minutes.
Why add an llms.txt on Ghost?
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 Ghost 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 Ghost
- Q&A markup: Ghost Admin → Settings → Code injection → Site Header → paste it. It's clean, site-wide, and survives updates — the strongest signal.
robots.txt: place arobots.txtat the root of your active theme's folder, then re-activate the theme (Ghost doesn't edit it from the admin).llms.txt: Ghost doesn't serve an arbitrary root file. With theme access, add a route inroutes.yaml(Settings → Labs) mapping/llms.txtto a template; otherwise the Q&A markup above is what makes your site citable.
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.
