Automatically Generate llms.txt to Improve AI SEO

llms.txt is designed to work alongside current web standards like sitemaps.xml and robots.txt, complementing them by providing context for allowed content and an overview for AI.

By providing relevant and structured information, llms.txt helps AI perform better during inference time when users seek support. This leads to better, more accurate, and more helpful answers and assistance, directly impacting user satisfaction and the utility of AI applications.

The TanaFlows theme automatically generates llms.txt for you - you don’t need to create this file. However, you need to enable this feature in Ghost Admin through the Labs route.

How to Enable Automatic llms.txt Generation

  1. Go to Settings > Labs > Routes

  2. Download the routes.yaml file

  3. Open with Notepad and add the following line at the beginning of the file:

    routes:
      /llms.txt/:
        template: llms
        content_type: text/plain

  4. Save the file and upload the modified routes.yaml back to Labs.

File default routes.yaml of ghost has the following content:

routes.yaml
routes:


collections:
  /:
    permalink: /{slug}/
    template: index


taxonomies:
  tag: /tag/{slug}/
  author: /author/{slug}/

File routes.yaml after you add the line above has the following content:

routes.yaml
routes:
  /llms.txt/:
    template: llms
    content_type: text/plain


collections:
  /:
    permalink: /{slug}/
    template: index


taxonomies:
  tag: /tag/{slug}/
  author: /author/{slug}/

Controlling Pages Added to llms.txt

By default, the following posts and pages will automatically be displayed in llms.txt:

  • Posts marked as Featured
  • Pages marked as Featured
  • 10 most recently published posts
  • Website owner information automatically pulled from your profile

When you publish a new post, llms.txt will automatically update for you.
