Configuration

The extension can be configured via Site Settings and page properties.

Site Settings

After adding the Site Set to your site configuration (see Activate the Site Set), you can configure the extension in Site Management > Settings.

llmsTxt.intro

type: text
Default: (empty)

Website description shown in the intro section of the llms.txt file. This text appears as a blockquote below the site title and helps AI crawlers understand the purpose of your website.

It is used for the llms.txt of the default language. The field llms.txt Intro of a language takes precedence and is the only intro for the other languages.

Example:

Your expert for tires, wheels, and automotive services since 1985.

llmsTxt.excludePages

type: string
Default: (empty)

Comma-separated list of page UIDs to exclude from the llms.txt index. Use this for pages that should not appear in the LLM index, such as imprint, privacy policy, or internal pages.

Example:

42,56,123

llmsTxt.includeHidden

type: boolean
Default: false

If enabled, hidden pages are also included in the llms.txt generation. This can be useful for staging environments or preview purposes.

llmsTxt.enableMarkdown

type: boolean
Default: true

If disabled, the .md Markdown variant is no longer served for any page on this site: .md URLs are left untouched and resolve as a normal 404 instead of being rewritten, and llms.txt no longer contains the Markdown hints (including the authentication hints for llmsTxt.apiKey) or per-page Markdown links.

llmsTxt.apiKey

type: string
Default: (empty)

API key for protected access to /llms.txt and .md endpoints. If set, requests without a valid API key will receive a 401 Unauthorized response. Leave empty for public access.

See API Protection for details on how to use API key protection.

Site Languages

Every enabled language of a site has its own llms.txt below its base, see Multi-Language Access. In Site Management > Sites, each language has an additional field:

llms.txt Intro

type: text
Default: (empty)
Key: llmsTxtIntro (per language in config/sites/<site>/config.yaml)

Website description shown in the intro section of the llms.txt of this language. It takes precedence over llmsTxt.intro, which is the fallback for the default language only. Other languages without this field have no intro.

Example:

languages:
  -
    languageId: 1
    title: English
    base: /en/
    llmsTxtIntro: 'Your expert for tires, wheels, and automotive services since 1985.'

Page Properties

Each page has an LLM tab in the page properties with the following fields:

Name	Type
llmsTxt.intro
llmsTxt.excludePages
llmsTxt.includeHidden
llmsTxt.enableMarkdown
llmsTxt.apiKey
llms.txt Intro
Exclude from llms.txt
LLM Priority
LLM Description
LLM Summary
LLM Keywords

Exclude from llms.txt

type: checkbox
Default: false

If enabled, this page will not appear in the llms.txt index. The page is also excluded from the Markdown output.

LLM Priority

type: number (slider)
Default
Range: 0-100

Higher values (0-100) cause the page to appear earlier in the llms.txt page list, before the other pages with the same parent page. The list follows the page tree, so a page never leaves its branch. Pages with the same priority keep the order of the page tree. Use this to highlight important pages for AI crawlers.

The priority is the same in every language: translations use the priority of the default language page, and the field is not shown in translations.

Recommendations:

80-100: Main landing pages, key services
50-70: Important content pages
20-40: Secondary pages
0-10: Low-priority pages

LLM Description

type: textarea
Default: (empty)
Max length: 500 characters

Custom description for this page in the llms.txt index. If empty, the page's SEO meta description (from the SEO tab) is used as fallback.

This description helps AI crawlers understand what the page is about.

LLM Summary

type: textarea
Default: (empty)
Max length: 2000 characters

Additional summary text, added to the notes of the page in the llms.txt index. Use this for longer explanations that don't fit in the description.

LLM Keywords

type: text input
Default: (empty)
Max length: 255 characters

Comma-separated keywords/topics for this page. These appear in the llms.txt index and help AI crawlers categorize the page content.

Example:

tires, wheels, alignment, services

robots.txt Configuration

To allow AI crawlers to discover and access your llms.txt file, add these lines to your public/robots.txt:

# Allow AI crawlers to access llms.txt
User-agent: GPTBot
Allow: /llms.txt

User-agent: Claude-Web
Allow: /llms.txt

User-agent: Anthropic-AI
Allow: /llms.txt

User-agent: Google-Extended
Allow: /llms.txt

Add the llms.txt of further languages as well, e.g. Allow: /en/llms.txt.

Note

The extension shows a notification in the TYPO3 Backend if your robots.txt does not contain a reference to llms.txt.

HTML Header Link

The extension automatically adds a <link> tag to all HTML pages to help AI crawlers discover the llms.txt file:

<link rel="alternate" type="text/plain" href="/llms.txt" title="LLM Content Guide">

The link points to the llms.txt of the page language, e.g. /en/llms.txt on English pages.

Note

When API key protection is enabled, this header link is automatically hidden to prevent unauthorized crawlers from discovering the endpoint.
