How to Create an llms.txt File? 5 Critical Things You Must Know

Written on July 16, 2025. Posted in Blog.

As search engines evolve with AI, traditional SEO is transforming rapidly. With systems like ChatGPT and Gemini now indexing structured information, having a correctly prepared llms.txt file is no longer optional-it’s essential.

In this guide, we will explore how to create an llms.txt file and highlight 5 critical points you must consider to ensure that your website stands out in AI-powered search environments.

1. Build Purpose-Driven Content Architecture

AI systems like LLMs (Large Language Models) prioritize intent-based content. It’s not just about what you say-it’s how and why you say it.

Key considerations:

Structure your website into topic clusters.
Ensure every URL listed in llms.txt is part of a logical hierarchy.
Use internal links that guide AI models through semantically related topics.

2. Use Structured Data Effectively

To fully utilize your llms.txt, every referenced page should include well-formed schema markup.

Tips:

Implement BlogPosting, FAQPage, or Article schemas using JSON-LD.
Avoid plugins that generate generic or duplicate schema data.
Ensure schema content matches the visible content.

3. Maintain Semantic Relevance

Modern AI models don’t rely on keyword repetition-they rely on semantic understanding.

To achieve this:

Include natural variations of your keywords such as “how to create llms.txt” or “llms.txt file structure.”
Keep your headings relevant and contextual.
Interlink articles on related topics like AI SEO, structured data, and SearchGPT.

4. Optimize Technical Health of the Page

If your pages load slowly or aren’t accessible, it doesn’t matter how great the content is-AI systems may still skip them.

Ensure the following:

Fast load speeds and responsive design.
Clean HTML and accessible layouts.
Pages must be crawlable, indexable, and free of script-blocking errors.

5. Focus on Engagement Signals

LLMs are trained on user interaction patterns-and that affects how your content is valued.

Recommendations:

Use clear CTAs (call-to-actions).
Suggest related content or tools to increase time on site.
Consider adding interactive elements like polls or forms.
