How to add llms.txt to WordPress (3 ways)

What llms.txt is

It is a text file at yoursite.com/llms.txt, written in Markdown. It works as a sitemap for AI systems: a site name, a one-paragraph description, then sections of links with a one-line note each, intended to point AI tools to the main pages without a full crawl. It is a proposal (llmstxt.org) rather than a standard: support varies between AI providers, none is obliged to read it, and there is no penalty for not having one.

One source for the file

Every method below produces the same file at the same address. If two plugins generate it, only one version is served, with no warning. Use one method and switch the others off. A physical file in the site root takes precedence over a plugin, because the web server returns it before WordPress runs. The FAQ at the end lists which source takes precedence in each combination.

Method 1: the setting in an SEO plugin

Yoast SEO, All in One SEO and Rank Math each added llms.txt support in 2025:

• Yoast SEO — Yoast SEO → Settings → Site features → under AI tools, switch on LLMS.txt → Save changes. Yoast writes a real file into your site root and refreshes it weekly by cron. It lists the five most recently updated items of each type, cornerstone content first. Not available on multisite.
• All in One SEO — Sitemaps → LLMs.txt tab, switch it on; you can also switch on llms-full.txt. Like Yoast it writes a real file into your site root, regenerated on a schedule.
• Rank Math — Rank Math SEO → Dashboard → enable the LLMs Txt module (switch to Advanced Mode if you do not see it) → General Settings → Edit llms.txt to choose post types, taxonomies and the item limit (100 by default).

These are full SEO suites. For a site that does not already use one, Method 2 or Method 3 adds llms.txt without installing a suite.

Method 2: the AumViso plugin

AumViso is a free plugin limited to AI search features: llms.txt, schema markup, XML sitemaps and internal links. It generates llms.txt on request: no file is written, and the content reflects the currently published content.

1. In your WordPress admin go to Plugins → Add New, search for AumViso, click Install, then Activate.
2. Once the plugin is active, yoursite.com/llms.txt is served, together with yoursite.com/llms-full.txt, the version with excerpts. The switch Serve /llms.txt from this site at the top of the llms.txt tab is on by default.
3. To adjust what goes in, open SEO/GEO in the admin sidebar and pick the llms.txt tab.
4. Site description — one paragraph shown at the top of the file. Leave it blank to use your site tagline.
5. Four switches decide the sections: Include Pages, Include Posts, Include FAQ / Glossary / Guides, Include Products. All are on by default. Max items per section is 50 (1–500).
6. Click Save, then View /llms.txt to see the result.

If the address returns a 404, go to Settings → Permalinks and click Save once; the plugin requires pretty permalinks. The file is cached for a day and rebuilt whenever you publish or update a post.

Method 3: a hand-written file

For a small site that changes rarely, a hand-written file is sufficient. Create a file named llms.txt in this format:

# Your Site Name

> One paragraph on what the site is and who it is for.

## Main pages

- [Services](https://yoursite.com/services): What we do and for whom
- [Pricing](https://yoursite.com/pricing): Plans and what each includes

## Guides

- [Getting started](https://yoursite.com/guides/start): First steps for new customers

Upload it to the root of the site (the folder that holds wp-config.php) with FTP or the host's file manager. The full format is at llmstxt.org. The file must be edited each time a page is added.

Checking the file

1. Open a private (incognito) window to avoid a cached or logged-in version.
2. Go to yoursite.com/llms.txt.
3. The page should show plain text beginning with # and the site name. A 404 means nothing is serving the file. An HTML page means a redirect or the theme is handling the address.
