What is LLMS.txt?
LLMS.txt is a proposed standard file that helps Large Language Models (LLMs) understand your website better.
Just like robots.txt tells search engine crawlers how to navigate your site,
llms.txt provides a human-readable summary specifically designed for AI systems.
When AI chatbots like ChatGPT, Claude, or Perplexity encounter your website, they can read this file to quickly understand:
- What your business or website does
- Key pages and their purposes
- How to accurately describe your products or services
- Contact information and key facts
Why Your Website Needs LLMS.txt
More users are finding businesses through AI chatbots. Give AI a clear picture of who you are.
Control how AI describes your business instead of letting it guess from fragmented page content.
Unlike complex SEO changes, LLMS.txt is a single file that takes minutes to create.
As this standard grows, early adopters will have a head start in AI visibility.
LLMS.txt File Format
The file uses a simple markdown-like format that's both human and machine-readable:

Platform-Specific Instructions
WordPress - Automatic with Ayzeo Plugin Recommended
The Ayzeo GEO SEO WordPress plugin automatically generates and maintains your llms.txt file. No manual work required - just install the plugin and it creates an optimized llms.txt based on your site content.
For other platforms, you'll need to create and upload the file manually:
Shopify
Go to Online Store → Themes → Actions → Edit code. Under Templates, add a new template called llms.txt.liquid with your content, then create a page pointing to this template.
Webflow
Upload llms.txt as an asset, then use custom code in your site settings to serve it from the root path.
Squarespace
Squarespace doesn't allow direct root file uploads. Create a page at /llms-txt and add a redirect from /llms.txt to that page, or use their code injection feature.
Custom HTML / Other Platforms
Upload the llms.txt file to your web server's root directory via FTP, cPanel File Manager, or your hosting provider's file management tool.
Best Practices
Be concise: AI models work better with clear, structured information. Avoid marketing fluff.
Update regularly: Keep the file current with your latest products, services, and contact info.
Include key facts: Add specific details AI might need - founding year, locations, specialties.
Link important pages: Help AI understand your site structure by linking key pages.

Frequently Asked Questions
Is LLMS.txt an official standard?
It's an emerging convention, similar to how robots.txt became a standard. While not officially ratified, it's gaining adoption as businesses optimize for AI discovery.
Do I still need JSON-LD if I have LLMS.txt?
Yes! They serve different purposes. LLMS.txt provides a high-level overview, while JSON-LD provides structured data for specific pages. Use both for maximum AI visibility.
How long should my LLMS.txt be?
Aim for 500-2000 words. Long enough to be comprehensive, short enough for AI to process efficiently. Focus on quality over quantity.
