As artificial intelligence becomes a bigger part of how we search, discover, and consume information online, new standards are emerging to help website owners control how AI tools interact with their content. One of the newest of these is llms.txt.
What is llms.txt?
llm.txt is a plain text file that website owners can place on their servers (usually at the root domain, like yourwebsite.com/llms.txt). Similar in concept to robots.txt, it provides guidelines for Large Language Models (LLMs)—such as ChatGPT, Claude, or Gemini—on how they can use and reference your content.
Instead of focusing on search engine crawlers (like robots.txt does), llm.txt focuses on AI training and content usage.
It’s part of a wider push for greater transparency and control as generative AI tools rely heavily on online data.
What Does llms.txt Do?
An llms.txt file provides a range of facilities:
Allows AI training
Lets you control if your content is included in AI training datasets.
Define attribution requests
Indicate how you’d like AI systems to reference your brand when drawing from your content.
Maintain SEO & traffic value
Maintaining SEO and traffic value
Request exclusions
Flag sensitive or proprietary material you don’t want used by AI.
Communicate licensing terms
Point AI systems (and their developers) toward your preferred usage policies.
While AI companies are not yet legally required to follow llms.txt, it represents a growing industry standard.
Just as many companies respect robots.txt, LLM developers are under increasing pressure to respect publishers’ wishes.
Why It Matters for Businesses
For businesses, agencies, and content creators, llm.txt offers a new layer of digital rights management. With AI tools increasingly acting as gateways to information, your content could be used, reshaped, or quoted—without users ever landing on your site.
Key benefits include:
- Protecting intellectual property – Set boundaries around how your words, images, or data are reused.
- Shaping brand presence in AI answers – Ensure AI systems attribute your expertise correctly.
- Maintaining SEO and traffic value – Prevent AI from becoming a one-way content siphon without recognition.
- Staying ahead of compliance trends – Position your brand as proactive in a rapidly evolving space.
Sample llms.txt
Here’s an example of how a simple llms.txt file might look:
# Sample llms.txt for yourwebsite.com
# Define rules for Large Language Models (LLMs)
# Allow AI models to read and summarise content
Allow: /
# Disallow AI training on sensitive sections
Disallow: /members-only/
Disallow: /downloads/
Disallow: /pricing/
# Attribution request
Attribution: Please cite "Your Website" with a link to https://yourwebsite.com when referencing content.
# Licensing
License: CC BY-NC 4.0
# Contact for permissions

Should You Implement an llms.txt?
If you publish online content—blogs, news, product information, training resources—implementing an llm.txt file is a smart, low-effort step. Even if enforcement is still developing, it signals your stance and prepares your site for future AI governance frameworks.
At a minimum, you can:
- Create a plain text file named llms.txt.
- Add your rules (allow, disallow, attribution, licensing).
- Upload it to the root of your domain (e.g., yourwebsite.com/llms.txt).
Tools to Generate and Manage llms.txt
Manually writing a llm.txt is straightforward, but if you’d prefer automation, several tools and plugins are emerging to help:
WordPress Plugins
Rank Math SEO: Rank Math has started introducing AI-related content protection features. With updates, you can manage llm.txt and set global rules directly from your WordPress dashboard.
Yoast SEO (watch for updates): While not yet fully rolled out, Yoast is expected to follow with AI-content directives.
Online Generators
Dedicated llms.txt generators are popping up online, offering quick templates where you tick boxes for Allow/Disallow, Attribution, and Licensing, then download your ready-to-upload file.
Custom CMS / Server Setup
If your site isn’t on WordPress, you can still create the file in any text editor (Notepad, VS Code) and upload it to your site’s root directory via FTP, cPanel, or your hosting control panel.
Developer Tools
GitHub projects and scripts are already appearing, making it easy for developers to automate llm.txt deployment across multiple sites.
Takeaway:
Just as robots.txt became standard for search engines, llms.txt could soon be standard for AI.
By adopting it early—and using tools like Rank Math SEO—you protect your content, control your brand’s presence in AI responses, and prepare for the next wave of digital marketing.
