It’s no secret. AI is here to stay. We see it everywhere from Chat GPT to Perplexity to Gemini to many more, search engines are seeing competition they have never experienced before. They need an LLMS.txt file.

If you have a website and want the LLMS (Large Language Models) to find your site’s content, you will not want to miss this. The LLMS.txt is a small file which can have a big impact.

What is included in an LLMS.txt file?

This file is read by the large language models, (think Chat GPT, Perplexity, Gemini, Claude) and gives that model an idea what they should look at on your site, what they should stay away from, and which models you would like to read your site.

Here is the list of what to include in an LLMS.txt file:

What parts of the site should LLMs be allowed to access?
(e.g., blog, resources, product pages)

What parts should be disallowed?
(e.g., private customer portals, internal documents)

Do you want to include a contact email or comment for LLMs?

You just need to answer each of these questions.
