Short answer: llms.txt is a small text file you put on your website to help AI tools understand and find your most important information. It works much like a table of contents written for AI. It doesn't guarantee anything, but it makes it easier for AI to provide accurate answers about your business - and that's becoming increasingly important as more people search via AI instead of regular search.
What is llms.txt, simply explained?
"LLM" stands forLarge Language Model– the kind of AI behind tools like ChatGPT and Claude.llms.txtis a text file you put at the top of your website (at the address dindomän.se/llms.txt) that clearly points out: this is our company, this is what we do, and here are the most important pages.
Simile: imagine a new employee starts and you give them a one-page cheat sheet with the essentials and links to the right documents - instead of asking them to read the entire intranet. llms.txt is that cheat sheet, fixed for AI.
Why should I care what the AI reads?
Because more and more customers are now asking an AI instead of Googling. When someone asks "which web agency in Jönköping can build e-commerce?" do you want the answer to be based on accurate, up-to-date information about you - not on old or misunderstood content.
Visibility in AI responses.If the AI understands what you do, you're more likely to be mentioned when someone asks about your industry.
Fewer misunderstandings.You reduce the risk of the AI confusing your services or drawing conclusions from the wrong side.
You are one step ahead.This is still new in 2026 – most competitors haven't even heard of it.
This area is sometimes called GEO (Generative Engine Optimization) or AEO (Answer Engine Optimization) – that is, optimizing for AI answers, much like SEO is about optimizing for search engines.
Is llms.txt the same as robots.txt?
No, but they are related.robots.txtis an old, established file that tells search engines which pages to visit.llms.txtis newer and is instead abouthighlightyour most important information in a way that is easy for AI to understand. One sets limits, the other points out what is important. You can have both.
Important to be honest about: llms.txt is a suggestion, not a law. Not all AI tools read the file, and it doesn't force anyone to do anything. But it costs almost nothing to post and can only help.
What should be in an llms.txt?
The file is written in a simple format (Markdown) that both humans and AI can read easily. A basis may include:
Company name and a sentence about what you do.
Your most important services or productsin a short list.
Links to key pages– services, about us, contact, frequently asked questions – with a brief description of each.
Location and contact details, if relevant to your customers.
Think quality before quantity. It's not about pasting everything in, but about pointing to the most important and describing it clearly.
How do I create and upload the file?
1. Write the content
Summarize the company and list the key pages in plain text. Write as if you were explaining to a new employee – short, to the point, without jargon.
2. Save it as llms.txt
A plain text file with exactly that name.
3. Put it in the root of the site
It should be located so that it can be accessed at dindomän.se/llms.txt - i.e. at the top, not hidden in a subfolder. How you upload it depends on your platform; this is often the step where it's nice to get help.
4. Keep it updated
Are you changing services or moving pages? Update the file. An outdated cheat sheet is worse than none.
Is llms.txt enough to be seen in AI?
No. llms.txt is a piece of the puzzle, not the whole picture. The most important thing is still that your website hasclear, accurate and well-structured contentthat actually answers customers' questions. AI draws its image of you from your entire online presence – llms.txt just helps it find the right one faster.
Summary
llms.txt is a simple, inexpensive way to help AI tools understand your business correctly – and it becomes more valuable to every customer who starts asking AI instead of Googling. It's not a substitute for great content, but it's a smart complement and a way to stay ahead of the curve.
