The llms.txt standard was proposed in September 2024 by Jeremy Howard, co-founder of Answer.AI, and the open specification is maintained at llmstxt.org<\/a>. It’s a community proposal, not an official standard from any AI company.\u00a0<\/p>\n\n\n\n With an llms.txt file, you highlight for AI tools the information about your business that they should focus on. This helps AI tools read your site more easily, as they go straight to your most important pages. The file itself is a curated list of links with short descriptions.<\/p>\n\n\n\n That makes it easier for them to pick the right page when a user asks about it. And when AI picks the right page, you have a better chance of getting recommended by ChatGPT<\/a> and other AI tools.\u00a0<\/p>\n\n\n\n This file is short and usually includes:<\/p>\n\n\n\n The llms-full.txt is a more detailed version of the llms.txt file. Instead of just linking to pages, it puts all your content into one file, so AI gets the full text in one place.<\/p>\n\n\n\n The adoption of llms.txt files is already growing. Hundreds of thousands of websites have published an llms.txt file, including major tech companies like Anthropic, Stripe, and Cloudflare.<\/p>\n\n\n\n Here are a few ways it may help improve how AI tools understand your website.<\/p>\n\n\n\n Important note:<\/strong><\/p>\n\n\n\n Major AI companies (OpenAI, Anthropic, Google) haven’t officially confirmed that they use llms.txt, so there’s no guarantee it directly boosts your visibility or citations.<\/p>\n\n\n\n In June 2025, Google’s Search Advocate, John Mueller, wrote on Bluesky: <\/p>\n\n\n\n However, Anthropic, the company behind Claude, has llms.txt files on parts of its documentation sites<\/a>, but it is not confirmed how they are used.<\/p>\n\n\n\n Our take is that the llms.txt file will not automatically improve LLM visibility<\/a>. However, it will not harm your website and may help provide clearer guidance for AI systems in the future. It is also quick and easy to set up, so it is worth adding.<\/p>\n\n\n\n Now, if you consider adding the llms.txt file, our tips can help you. It’s one easy step you can take to support your wider AI SEO<\/a> efforts.<\/p>\n\n\n\n There are a few llms.txt generators that you can consider during that process.<\/p>\n\n\n\n WordLift: <\/strong>The WordLift llms.txt generator<\/a> <\/strong>takes a different approach from the other tools. Instead of crawling listing URLs, it analyzes your content to prioritize your most important pages.<\/p>\n\n\n\n Try any of those tools and see which one gives you the best results.<\/p>\n\n\n\n This step is somewhat symbolic: AI tools can help you create an llms.txt file so they can get accurate information about your business.<\/p>\n\n\n\n To create the llms.txt file for the SayNine website, we used Claude.ai. The first thing to do is write a detailed prompt. Here’s an example you can use.<\/p>\n\n\n\n Create an Structure it as follows:<\/p>\n\n\n\n Formatting rules:<\/strong><\/p>\n\n\n\n Before writing, ask me for:<\/strong><\/p>\n\n\n\n Then enter this prompt, and Claude will generate an llms.txt file for you.<\/p>\n\n\n\n Once your llms.txt file is ready, your developers just need to upload it to your site’s root directory (e.g., yourdomain.com\/llms.txt) so AI tools can find it.<\/p>\n\n\n\n Whether you used an llms.txt generator or Claude, as we did, make sure your file meets these criteria:<\/p>\n\n\n\n There is an active discussion around llms.txt files. We shared whether it\u2019s worth adding one and how to set it up in an easy way.<\/p>\n\n\n\n Notably, in May 2026, Google added llms.txt to Chrome Lighthouse’s new “Agentic Browsing<\/a>” audit, not as a ranking factor, but as an AI-readiness check, which is one more sign the standard is gaining more popularity.<\/p>\n\n\n\n But here is the truth you should know: you can\u2019t achieve high AI visibility with just one step. It requires a series of actions, such as investing in listicles and building brand mentions. If you need help, consider investing in AI SEO services<\/a> to improve your visibility in AI search results and answers.<\/p>\n\n\n\n\n
