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

What is GEO?→Carrd 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 Carrd site and cite it in their answers. The steps are concrete and take a few minutes.
Why add an llms.txt on Carrd?
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 Carrd 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 Carrd
- Q&A markup: add an “Embed” element in “Code” mode and paste it — it renders in the page, which is valid for JSON-LD (requires Carrd Pro).
llms.txt: Carrd only lets you edit a fixed set of files (robots.txt,ads.txt, on Pro Plus), not an arbitraryllms.txt. The Q&A markup still makes your site citable.- Custom domain behind Cloudflare? A Cloudflare Worker on
your-site.com/llms.txtcan serve the file at your root.
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.
