Does llms.txt help your hotel appear in AI? What Google, OpenAI and the studies say (2026)

Updated: 9 November 2026

More and more agencies offer hotels "an llms.txt to appear in ChatGPT". Before paying for it, it is worth knowing what it is and what the companies themselves say. In short: today no official documentation says llms.txt helps you appear in AI, and Google states in writing that its search engine does not use it (sources at the end).

What llms.txt is

It is a 2024 proposal by Jeremy Howard (llmstxt.org): a text file at your-site.com/llms.txt with a title, a short summary and lists of links to the important pages, meant to help a language model find the essentials. It is a proposal, not a standard adopted by search engines.

What Google and the other companies say

Google: "You don't need to create new machine readable files, AI text files, or markup to appear in these features" (AI Overviews and AI Mode). Its 2026 AI optimisation guide adds that its search engine does not use these files and that having them "will neither harm nor help" your visibility.
OpenAI, Anthropic, Perplexity and Apple: their documentation for websites explains their crawlers and robots.txt, but does not mention llms.txt. We have found no official page saying they read it for their answers.
A company publishing its own llms.txt (some do in their technical documentation, for coding assistants) does not mean its crawlers use it to recommend websites.

What the studies say

Two studies by SEO companies, with 2025 and 2026 data, find no effect: SE Ranking analysed about 300,000 domains and found no relationship between having llms.txt and being cited by AI; Search Atlas compared 13,911 domains across six assistants and the difference was 0.42 points out of 100. They are correlation studies, not experiments, but they point the same way as the official documentation.

What does help (according to the companies themselves)

Letting each assistant's search crawler in through robots.txt (OAI-SearchBot, Googlebot, Claude-SearchBot, PerplexityBot, Applebot, Bingbot). We have a guide to check it in five minutes.
Having the important information as text on the page (address, type of property, amenities, how to book), not only in images or PDFs.
Correct schema.org structured data: it helps understanding, although it is not an entry ticket.
Being present in the sources AI cites for hotels (Google listings, Tripadvisor, local guides).

If you still want one

It does no harm and costs nothing: Google says it is fine if other services use it. Ten lines are enough: the property name as the title, one sentence on what it is and where, and links to the booking page, the rooms and the terms. What makes no sense is paying for it as if it were the key to appearing in AI.

How iQuota helps

iQuota publishes an llms.txt for each property because it costs nothing, but does not sell it as a guarantee: what we really do is an official text page, open to search crawlers and with structured data, and a connector that gives compatible assistants real availability and prices with direct booking and payment at the property. Nobody can guarantee that an AI will recommend you.

Frequently asked questions

Do I need llms.txt to appear in ChatGPT or Google?

No. Google says no special files are needed for its AI features, and OpenAI does not mention it in its documentation: for ChatGPT, what matters is that OAI-SearchBot can read your website.

Can having it hurt me?

No. Google says it neither helps nor harms visibility in its search engine.

An agency is offering it to get me into AI. What should I do?

Ask for an official source saying an assistant uses it. Today there is none; first check robots.txt and that your information is in text.
