What Is llms.txt and Should Your Website Have One?

Someone on LinkedIn told you llms.txt is "the new robots.txt." A vendor offered to add one to your site for a fee. Now you are wondering whether you are about to miss the biggest shift in search, or about to pay for a file nobody reads.

Fair question. So, what is llms.txt, and does your business actually need it?

This guide gives you the plain answer, what Google itself says, and a simple way to decide.

Quick Answer

llms.txt is a proposed Markdown file, placed on your website, that gives AI tools a short, curated summary of your site and links to your key pages. Google says Google Search does not use it, and you do not need it to appear in Google. For most UAE business websites it is optional and low priority.

Key Takeaways

• llms.txt is a plain Markdown file that lists your most useful pages for AI tools.
• It is an open proposal, not a finalized standard.
• Google says Google Search ignores llms.txt files.
• No source I could verify shows it improves AI citations, so do not expect a ranking or visibility boost.
• Creating one is allowed and cheap, but crawlable, clear content matters more.

What Is llms.txt?

llms.txt is a text file written in Markdown, saved at the root of your website (for example, yourdomain.com/llms.txt). It acts like a short guide for large language models: who you are, and which pages matter most.

The idea is simple. AI tools can struggle to pull key facts from cluttered web pages full of menus, scripts and banners. A tidy summary with direct links could save them the effort.

What does an llms.txt file look like?

The proposal's format is straightforward. Only the title line is required:

# Example Business Name

> One or two sentences explaining what the business does.

## Services

- [Web design](https://example.com/web-design/): What we build and for whom
- [SEO](https://example.com/seo/): How our SEO work is structured

## Optional

- [Blog](https://example.com/blog/): Guides and articles

The required part is the H1. The summary quote, body text and link lists are optional. An H2 section named "Optional" holds secondary links that can be skipped.

How is llms.txt different from robots.txt and sitemap.xml?

These three files are often confused. They do different jobs.

So llms.txt does not block or allow anything. It is a reading guide, not a rulebook.

What Is llms.txt Used For, and Who Supports It?

The idea comes from the llms.txt proposal, which lists Jeremy Howard as its author. It says thousands of sites publish the file, and that some documentation platforms generate it automatically.

The same page also says the specification is open for community input. In other words, it is a proposal that people are trying out, not a rule that search engines or AI companies must follow.

Chrome's Lighthouse tool now includes an audit for it. Chrome's documentation calls llms.txt an "emerging convention" and says that providing the file is optional at the moment. That audit concerns how ready a site is for browser-based AI agents. It says nothing about rankings.

Does Google Use llms.txt?

No. Google's guide to AI features in Search says you do not need new machine-readable files, AI text files, markup or Markdown to appear in Google Search. It says Google Search ignores llms.txt files, though it is fine to create one if you want.

So adding llms.txt will not help you rank in Google or appear in AI Overviews. What Google does ask for is simple: make sure your content is crawlable.

Will llms.txt Get You Cited by ChatGPT and Other AI Tools?

This is the claim sellers lean on, so be careful with it.

I could not find a verified source showing that ChatGPT, Perplexity, Claude or any other AI assistant reads llms.txt files, or that having one earns more citations. Anyone who promises that is guessing.

What you can say honestly:

• The format exists and is documented.
• Some developer-documentation sites use it.
• Google Search does not use it.
• Chrome treats it as optional.

If a provider announces support in future, the picture could change. For now, treat llms.txt as an experiment, not a growth strategy.

Should Your Website Have an llms.txt File?

It depends on what your site does. Use this table as a guide.

For most readers of this blog, the honest answer is: you can add one, but do not spend real budget on it. At Milaaj Brandset, we would put your time into fixing weak pages and unclear answers before touching a new file.

How Do You Create an llms.txt File?

If you decide to try it, the work is small.

1. Pick your key pages. Choose 5 to 15 that explain your business best: services, pricing guidance, about and your strongest guides.
2. Write the title and summary. Use your business name as the H1, then one or two plain sentences.
3. List the links. Group them under short H2 headings and add a brief note after each.
4. Save it as llms.txt. Use plain text with Markdown formatting.
5. Upload it to your site root. It should open at yourdomain.com/llms.txt.
6. Keep it current. Update the file when you add, move or remove important pages.

Make sure it returns a normal page rather than an error. Chrome's audit flags server errors when it tries to fetch the file. Your developer can handle the upload, and a web development team in Dubai can add it to your site or CMS quickly.

What Should You Do First Instead?

Google's guidance stresses crawlable content. These basics help your site whichever tool reads it:

• Make content crawlable. Do not hide key pages behind logins or scripts.
• Answer real questions clearly. Put the direct answer near the top of the page.
• Keep pages accurate and updated.
• Make it clear who you are, where you operate and what you offer.

What Are the Common llms.txt Mistakes?

• Treating it as a ranking trick. Google says it ignores the file.
• Stuffing it with keywords. It is a guide for readers and tools, not a keyword list.
• Linking to dead or outdated pages. A stale list is worse than none.
• Copying your whole sitemap into it. The idea is curation, not volume.
• Paying for it as a large project. It is a small file.
