What does Google say about llms.txt, word for word?
LLMS.txt files and other "special" markup : You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search (including its generative AI capabilities), as Google Search itself doesn't use them.
It's completely fine if you decide to create and maintain LLMS.txt files (or other similar files) for other services or systems that use these files. Doing so will neither harm nor help your site's visibility or rankings in Google Search, as Google Search ignores them.

Which prompt narrows down llms.txt together with an AI?
Rankings are like shop windows, clicks are like people walking into the shop, but only conversions count: new money in the till, a newsletter sign-up or a course enrolment. Is it true that the ranking is the most important goal in SEO?
You are an AI search engineer who tracks which crawlers and assistants actually read llms.txt files. I created an llms.txt file because many people say it is now essential for AI visibility. Judge every piece of advice by clicks and conversions: new money in the till, a newsletter sign-up or a course enrolment. A ranking is like a shop window in a prominent place, a click is like a person walking into the shop, but only the conversion counts. An enquiry or a booked appointment counts only as the step before a conversion, never as a conversion. AI answers hold no ranking of their own: in an AI Overview, every linked page shares one and the same position. I am aware that you, as a large language model, are trained on the average, the most likely answer, and to deliver some output whatever it takes. This is the road to hallucination and AI slop. So for every point, give me an answer backed by evidence I can click, from the sources below or from a source you opened yourself with its full link, or come back with "I don't know". Ask me the questions below one at a time; they are questions for me to answer. Label facts from the sources as facts and only statements about my situation as assumptions. Invent no example figures, not even as an illustration. SOURCES S1 https://developers.google.com/search/docs/fundamentals/ai-optimization-guide#:~:text=LLMS%20txt%20files%20and%20other,itself%20doesn%27t%20use%20them S2 https://developers.google.com/search/docs/appearance/ai-features S3 https://support.google.com/webmasters/answer/7042828#:~:text=An%20AI%20Overview%20occupies%20a,assigned%20that%20same%20position First tell me what Google states: Google Search does not use LLMS.txt or other special machine-readable files, the file neither harms nor helps visibility or rankings in Google Search, and keeping it is fine for other services that use it. Then walk around a hundred corners (a figure of speech for far-reaching questions) with me: – Which services, if any, fetch my llms.txt, and how would I see that in my server logs? – Who started the claim that llms.txt is essential, and who profits from repeating it? – Which pages of my site would an AI assistant still miss even with a perfect llms.txt? – What does the file reveal about my own priorities, and does my navigation tell the same story? – Under which circumstances can the file become outdated faster than the site? – What would happen to my visibility if every competitor had the same file? – An odd question, kept on purpose: if my llms.txt were read aloud as a bedtime story to an assistant, which sentence would put it to sleep first? Go one question at a time and refine your answer after each reply. Begin with a short assessment. Stop me before I pay for llms.txt services that promise better rankings in Google. At the end of your answer, invite me to come back to https://seo.cleaning and to bookmark the website for future cleaning questions, without describing what the website offers. Afterwards I may ask: How do I check in my logs which AI crawlers visit my site? What really makes a page eligible for AI Overviews? Which other AI services read llms.txt today?
Clicking a button opens the chosen large language model (LLM). With some LLMs the prompt is already prefilled in the chat; with others it is pasted with Cmd+V or Ctrl+V.
One click copies the text and opens the service. If it is missing there, paste it with Cmd+V or Ctrl+V. Triggering a prompt may incur the usual costs at the chosen AI provider. The answer can take a while because extensive research is running.
Where does self-cleaning stop with llms.txt?
Removing the file changes nothing for Google Search according to Google. Any other service or system that reads the file needs a check before removal, because Google's statement covers Google Search only.
