llmsTxt.baseUrl

type: string
Default: (empty)

Full URL of the website (e.g., https://example.com). This is used as the base URL in the generated llms.txt file. If empty, the site's base URL from the site configuration is used.

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.

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.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.

Page Properties

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

Name	Type
llmsTxt.baseUrl
llmsTxt.intro
llmsTxt.excludePages
llmsTxt.includeHidden
llmsTxt.apiKey
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. Use this to highlight important pages for AI crawlers.

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 shown as a blockquote 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

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">

Note

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