Generate Your Website’s llms.txt File with This Free Prompt

If you want your website to have a better chance of being referenced or understood by large language models (LLMs) like ChatGPT, you may have seen talk online about creating an llms.txt file. While not an official standard (yet), this emerging best practice could become one of the ways AI tools better understand your site’s purpose, structure, and value.

So we’re giving away a FREE prompt ( BELOW ) you can use with any advanced AI tool (like ChatGPT 4o or similar agents) to automatically generate your own llms.txt file.

This is ideal for:

  • Website owners who want to future-proof their content
  • SEO experts looking to get ahead of AI search trends
  • Marketing teams managing content-rich sites
  • eCommerce managers who want LLMs to better grasp product categories

A Few Important Disclaimers

  • llms.txt is not an official internet standard like robots.txt or sitemap.xml.
  • There is no current guarantee that OpenAI, Google, Perplexity, or other AI models are actively crawling or using llms.txt files for training or retrieval.
  • Think of it as conceptual metadata, similar to how schema.org started, and a proactive move in case it becomes supported or cited in the future.
  • Adding this file won’t magically boost your AI rankings overnight, but it may help language models better understand your site’s structure, offerings, and expertise if adopted.

PROMPT:

Free Prompt to Generate an LLMS.TXT file: Just Copy and Paste Into your ChatGPT AI Agent or other AI Tool (Modify as needed)
Once completed, just upload to your websites root directory so that ( www.websitenamehere.com/llms.txt ) opens up for you.

Objective: Generate a high‑quality llms.txt file for a given website. The file should help language models quickly understand and reference the site’s most valuable content.

Instructions:

  1. Analyze the website’s content hierarchy
    • Inspect any available XML or HTML sitemaps (product, page, post) and explore navigation menus to identify major product categories, services, key informational pages, and blog or news posts.
    • Focus on top‑level categories and representative subcategories or key products, rather than listing every single URL.
    • Identify important support or policy pages (e.g., About, Contact, Terms, Privacy, Shipping & Returns).
  2. Select and curate content
    • For each major category, select a primary landing page and a few representative subcategories or high‑value product pages.
    • Include links to authoritative guides, how‑to articles, calculators, training programs or other resources.
    • Choose a handful of blog posts or case studies that showcase different topics (tutorials, industry insights, success stories). Avoid listing dozens of posts.
    • Exclude low‑value pages such as checkout flows, login pages, or marketing fluff.
  3. Draft clear descriptions
    • Use concise, factual descriptions (10–15 words) that explain what each page covers.
    • Avoid hype or redundant repetition of the page title.
    • When summarizing subcategories, group them in parentheses for brevity.
  4. Build the llms.txt in Markdown
    • Start with an H1 title containing the website or company name and a short descriptor.
    • Add a blockquote (prefaced by >) that succinctly describes what the business does and who it serves.
    • Optionally include a sentence explaining that the list is curated for AI consumption.
    • Organize content with H2 headings such as:
      • ## Product categories (or Services if it’s a service business)
      • ## Representative pages or ## Popular products
      • ## Guides & resources
      • ## Articles & case studies
      • ## Policies & support
    • List each link as a bullet (- [Title](URL): description) under the appropriate section.
    • Keep the file in UTF‑8 encoding and ensure it stays well under 100 KB by curating rather than exhaustively listing every URL.
    • Add an optional “Usage guidelines” section stating how you’d like AI models to attribute or use the content, and include an HTML comment like <!-- Last updated: YYYY‑MM‑DD --> for version tracking.
  5. Validate and publish
    • Verify that all URLs return HTTP 200 and are publicly accessible.
    • Check the Markdown structure (one H1, proper headings and bullets).
    • Place the final llms.txt at the website’s root and, if possible, add a line in robots.txt (Llmstxt: /llms.txt) to aid discovery.
    • Plan regular updates (e.g., quarterly) to reflect changes in products, services or content.

Deliverable: Provide the full llms.txt file content, formatted as described above and ready to be uploaded to the root of the target website.
