What Is llms.txt, And Does Your Business Website Need It?

If someone recommends adding llms.txt to your website, the first question should be simple: what job will it do?

An llms.txt file is a proposed way to give AI tools a concise guide to a website’s information. It can point them towards useful resources. It is not a guarantee that an AI assistant will recommend your business.

For an SME owner or marketing manager, that distinction matters more than the file format.

What Is In The File?

The llms.txt proposal describes a Markdown file containing a site or project name, with optional background information and organised links. Markdown is a simple text format that can include headings and links.

The file is commonly placed at /llms.txt. The current proposal also allows it within a section of a site, covering information under that path.

Think of it as a short reading guide rather than a copy of the entire website. A compatible tool can use the guide to find more detail, but publishing it does not prove that a particular platform has read it.

Does It Help You Appear In Google’s AI Answers?

Google says that websites do not need new AI text files or special markup to appear in its AI features. Its guidance on AI Overviews and AI Mode points back to established search requirements and useful, accessible content.

That is not a statement about every AI product. Different services can discover and use information differently.

It does mean you should be cautious about a proposal that presents llms.txt as an essential Google ranking requirement. Ask the supplier to distinguish a documented platform requirement from an experiment or a recommendation.

What Would Be Useful To Include?

Begin with the questions people ask about your organisation. Which pages answer them reliably?

For example, a training provider might want its course descriptions, entry requirements and application guidance to be easy to locate. A software company might prioritise documentation and support instructions. These are planning examples, not proof that an AI platform will use the file.

Choose material you are comfortable making public. Do not include private documents, unpublished prices, internal instructions or links that expose restricted information.

Then check the descriptions. A link labelled as a full pricing guide should not lead to a page that only says “contact us”. An accurate summary is more useful than a generous claim about what the reader will find.

Fix The Website Before Adding A Second Description Of It

An extra file cannot resolve contradictory service information or make an incomplete page answer a customer’s question.

Before commissioning one, review the essentials:

• Can a visitor understand what you offer?
• Are the important details written as readable text?
• Do links lead to current information?
• Are policies, contact details and service descriptions consistent?
• Is there someone responsible for keeping them up to date?

If those questions reveal bigger gaps, deal with them first. Otherwise, you risk maintaining a polished summary of a website that still leaves people confused.

How Should You Judge The Work?

Ask for a clear explanation of what was added and how it will be maintained. Review the selected pages yourself, not only a screenshot showing that a file exists.

An independent content check is useful: give a colleague a few realistic customer questions and ask whether the linked material answers them. This tests the quality of the information without pretending to measure an AI platform’s behaviour.

If you later assess AI visibility, keep the evidence separate. A file being available, a tool requesting it, and an assistant citing your business are different observations. None should be reported as another.

Should You Add It?

It can be a reasonable, limited addition when you have useful public material and a clear maintenance plan. It should not displace improvements that help real customers understand and use your website.

Ask what problem the proposal addresses, what evidence supports it, and what remains uncertain. Be wary of any promise that a small file will secure recommendations.
