Frequently Asked Questions

Why do I need a llms.txt file?

Think of llms.txt file just like the sitemap.xml file that you have for Google crawlers. But, llms.txt file is built for LLMs like ChatGPT, Perplexity and Claude. It helps these LLM crawlers to understand your website content better.

What is the difference between llms.txt and llms-full.txt file?

llms.txt usually contains a basic list of available Large Language Models (LLMs) with essential details. llms-full.txt is a more detailed version, including additional metadata like parameters, architecture, and performance benchmarks. The "full" version provides deeper insights, while the standard version is more concise for quick reference.

Do I need different files for my sub-domains or sub-folders?

It depends. If you have any developer documentation, it's highly recommended. Rest you can decide on a case by case basis. For example, if you have a lot of case studies with interesting insights, you should consider creatine one for that sub-domain or sub-folder.

What if I dont want LLMs to read some of my site content?

Just like how you informed Google crawlers what pages, folders and sub-domains to crawle and which ones to avoid, you can do the same thing in llms.txt file.

Is this a standard now?

Yes and no. This is one of those things that someone suggested and a lot of companies started doing it. In September 2024, Jeremy Howard suggested creating llms.txt file so that crawlers for different LLMs can read the website well. The thought process is quite similar to creating robots.txt and hitemap.xml files for search engine crawlers.

Do I need llms.txt file if I already have sitemap.xml and robots.txt file?

We believe it's a good idea. Given that most of the big LLM companies themselves have started using llms.txt files makes us believe that its an early trend and it will help with ranking and mentions in the LLM ecosystem / answers.

What other websites have created llms.txt files?

How do I know if this is helping me?

You can keep tracking the referral in your analytics dashboards. You should already see some traffic coming from ChatGPT and other LLMs.
