# Adding llms.txt to WordPress

> Three ways to publish a spec-compliant llms.txt on WordPress — plugin-free upload, a snippet, or a plugin — plus how to verify it.

WordPress powers a huge share of the web, and adding an llms.txt is quick. The file just has to be served at `https://yoursite.com/llms.txt` as plain text.

## Option 1 — Upload the file (simplest)

Write your file (see [how to create an llms.txt file](/guide/how-to-create-llms-txt)), then upload `llms.txt` to the root web directory (often `public_html/`) via your host's file manager or SFTP. Done — no plugin needed.

## Option 2 — Serve it with a snippet

If you can't write files, add a tiny route. Drop this in your theme's `functions.php` (or a code-snippets plugin):

```
add_action('init', function () {
  if (trim($_SERVER['REQUEST_URI'], '/') === 'llms.txt') {
    header('Content-Type: text/plain; charset=utf-8');
    echo "# My Site\n\n> Short summary.\n\n## Docs\n- [Start](https://mysite.com/start): Get going\n";
    exit;
  }
});
```

## Option 3 — Use a plugin

Several SEO/AI plugins now generate llms.txt from your pages automatically. Handy, but review the output — auto-generators often include too many links or marketing copy. Keep it curated.

## Watch out for these

  - **Caching/CDN:** purge your cache after publishing so the file is served.

  - **Right location:** it must be at the domain root, not `/blog/llms.txt`.

  - **Plain text:** serve as `text/plain`, not HTML.

## Verify it

Run your domain through the [validator](/) — it confirms the structure and that every linked page actually loads.
