Does a real estate agent's website need an llms.txt file?

What is an llms.txt file?

An llms.txt file is a plain Markdown file placed at the root of a website. It lists the site’s most important pages, to give a language model a curated map of the site at the moment it answers a question. Jeremy Howard of Answer.AI put the format forward in September 2024 as a proposal published at llmstxt.org.

The file contains no directives and cannot block or permit anything. The file will not stop a crawler, prevent training on a site’s content, or restrict any AI system from reading a page. That makes it a different kind of file from robots.txt.

What does Google say about llms.txt?

Google's Search Central documentation on optimizing for generative AI features was updated 15 June 2026. It states that site owners need no new machine-readable files, AI text files, markup or Markdown to appear in Google Search. That includes its generative AI features. Google Search itself does not use them. The same page states that maintaining such files will neither harm nor help a site's visibility or rankings in Google Search.

Gary Illyes of Google spoke at the Search Central Deep Dive event in the Asia Pacific region on 23 July 2025. He said Google does not support llms.txt and is not planning to. Google's position has been stated in documentation and on the record, not inferred from testing.

Do ChatGPT, Claude, Gemini or Perplexity read a website's llms.txt file?

None of the major AI providers has publicly committed to reading a third-party llms.txt file or to using it as a retrieval or citation signal. OpenAI's own crawler documentation governs its bots through robots.txt and does not mention llms.txt.

Several AI companies publish an llms.txt file for their own developer documentation, which is a separate matter from their crawlers consuming other sites' files. A company publishing the file is not evidence that the company's crawler reads anyone else's.

How many llms.txt files actually get requested by anything?

Ahrefs reported in June 2026 that it analyzed 137,210 domains and found that 97 percent of the files on those domains received zero requests during May 2026. Around 28 percent of the domains in that dataset had a valid file at all.

Top Real Estate Systems has not independently verified the Ahrefs dataset and reports the figure as a vendor study rather than as a measurement of its own. The direction of the finding is consistent with Google's documented position that Google Search ignores the file.

Is there any situation where an llms.txt file is genuinely useful?

The file has a real use on developer documentation sites. There, AI coding assistants are pointed at the file directly, so they find the right reference pages without wasting context. Google's Chrome team has also added an experimental llms.txt check to its agentic browsing audits, which concerns AI agents completing tasks on a site rather than search visibility.

A residential real estate agent's website is neither developer documentation nor a site agents transact on. For that site the file costs nothing and does nothing.

If an agent wants one anyway, what goes in the file?

The format is set out in the original proposal at llmstxt.org. The file is plain Markdown, usually placed at the root of the site. The only required part is a top heading (H1) with the name of the site. After that the proposal describes an optional one-line summary in a blockquote, a few lines of detail, and then sections under H2 headings that each list links in the form “[page name](url): short note.” A section headed “Optional” marks links an AI tool can skip when it needs a shorter version. The proposal also suggests publishing a Markdown copy of each page at the same address with .md added.

For an agent, a sensible one is short: the agent’s licensed name and brokerage as the heading, a one-sentence summary of who they help and where, and links to the about page, each town page and the most useful answers. Keep it current when pages change. Top Real Estate Systems keeps one on its own site because it takes minutes to maintain, not because any search engine has said it helps rankings.

## Pages
- [About Jane](https://example.com/about/): license, brokerage and service area
- [Selling in Gonzales](https://example.com/gonzales/): pricing, timing and the local market
- [Buyer questions](https://example.com/buyers/): agreements, inspections and closing

## Optional

The example is illustrative; the names and links are made up.

What should a real estate agent buy instead of an llms.txt package?

An agent who wants to be named in AI answers should spend on the things assistants demonstrably read. That means an accurate Google Business Profile, genuine reviews, pages that answer real client questions in plain language, and correct listings on the sites that name the agent. Google's own guidance is that ordinary search quality work is what makes a page eligible for its AI features.

Top Real Estate Systems does not sell llms.txt files, schema markup as a ranking product, or guaranteed rankings, and states that in writing. A vendor selling an AI-readability file as a ranking fix is selling something the search engine has published that it does not use.

Where do the facts on this page come from?

Every figure on this page is attributed to a named, linked source published by Google, by the National Association of REALTORS, or by Top Real Estate Systems itself. Anything Top Real Estate Systems has not independently verified is labelled as unverified at the point where it appears.
