llms.txt is a small file at your site root that tells AI assistants what you do and which pages matter. Adding it helps ChatGPT, Perplexity, and agents cite you correctly. Here is how to add it on each platform.
Plain HTML
Create llms.txt in your site root next to index.html:
# Your Brand > One sentence on what you do. ## Docs - [About](https://yoursite.com/about) - [Pricing](https://yoursite.com/pricing)
WordPress
- Go to Tools → Theme File Editor (or edit via FTP).
- Add
llms.txtto the theme root, or drop it in the site root via FTP/cPanel File Manager. - Or use a plugin that lets you add root files.
Shopify
- Go to Online Store → Files and upload
llms.txt(it will be served from your CDN root). - Confirm at
https://yourstore.com/llms.txt.
Webflow
- Use Project Settings → Custom Code is not for raw files.
- Instead, host
llms.txtvia Webflow's asset CDN, or add it through your connected custom domain's file host.
