The llms.txt standard

What llms.txt is and why your site should have one.

llms.txt is an emerging standard — similar to robots.txt — that provides AI crawlers with a structured summary of your website. While robots.txt tells bots where they can go, llms.txt tells them what your site is about and how to use the information.

What goes in an llms.txt file

A typical llms.txt file includes: your business name and description, primary services or products, target audience, key pages to index, content licensing information, and preferred citation format. It's a plain text file placed at the root of your domain (yoursite.com/llms.txt).

Why it matters

Sites with an llms.txt file get crawled more frequently by AI platforms that support the standard. It's like giving AI a executive summary of your business — instead of making the AI figure it out by crawling dozens of pages, you hand it the key information directly.

How to create one

You can generate an llms.txt file instantly using VisibAI's free llms.txt Generator tool at getvisibai.com/tools/llms-txt-generator. Enter your URL and it creates a properly formatted file you can upload to your website root directory.

Adoption status

The llms.txt standard is still emerging, but early adopters report improved crawl rates and better AI understanding of their content. Given that it takes 2 minutes to create and upload, there's no reason not to add one — even if not all AI platforms support it yet, those that do will benefit from it.
