✅ Your llms.txt File

Copy and upload to your site root as llms.txt


      
📋 How to deploy: Save this as llms.txt and upload to your server root so it's accessible at yourdomain.com/llms.txt. For WordPress, upload via FTP or File Manager to the public_html folder.

What Is an llms.txt File?

An llms.txt file is a plain-text, Markdown-formatted file placed at the root of your domain that tells AI language model crawlers which pages matter most. It sits alongside robots.txt and gives systems like GPTBot, ClaudeBot, and PerplexityBot a prioritised map of your content.

As AI search engines now handle more than 50 percent of all queries globally, giving AI systems a clear content hierarchy has become a practical necessity for visibility. This free llms.txt generator builds a correctly formatted file in under two minutes with no coding required.

Where robots.txt acts as a gate controlling crawler access, llms.txt acts as a signpost directing AI models toward your highest-value pages. Together the two files form the foundation of modern AI search optimisation.

Why Your Site Needs an llms.txt File

AI-referred web sessions grew 527 percent between January and May 2025 according to SparkToro research, and ChatGPT now has over 900 million weekly active users. Without an llms.txt file, AI crawlers must infer your content hierarchy from links and schema alone. That increases the risk of AI systems surfacing outdated pages or low-authority posts instead of your flagship resources.

How to Use This llms.txt Generator

Enter your site name and a one to two sentence description. This description becomes the entity definition AI models use when attributing content to your brand. Next, add the URLs and short titles of your most important pages including your best-performing articles, key service pages, and cornerstone content. Optionally add any pages you want AI crawlers to skip, such as login pages, search results, or thin archives.

Click Generate to produce your llms.txt output. Copy the text, save it as a plain .txt file named exactly llms.txt, and upload it to your domain root at https://yourdomain.com/llms.txt. On WordPress, upload via FTP to the public_html folder or use a file manager plugin. Confirm it loads correctly before submitting your sitemap for recrawl.

FilePurposeControlsAudience
robots.txtCrawler access gateWhich URLs crawlers can visitAll crawlers
llms.txtContent priority guideWhich pages AI should prioritiseAI language models
sitemap.xmlURL discovery mapWhich URLs exist and when updatedAll crawlers

Use all three files together. robots.txt controls access, llms.txt controls AI priority, and sitemap.xml enables discovery. A site with all three files gives AI search engines the clearest possible picture of your content and earns more consistent citation across ChatGPT, Perplexity, and Google AI Overviews.


Frequently Asked Questions About llms.txt

What is an llms.txt file?+
An llms.txt file is a plain-text file at your domain root that tells AI language model crawlers which pages to prioritise. It follows a Markdown-based standard introduced in 2024 and is now recognised by crawlers for ChatGPT, Claude, and Perplexity. Adding it gives you direct control over how AI systems discover and cite your content, reducing the chance that low-value or duplicate pages appear in AI-generated answers about your brand.
Which AI crawlers read llms.txt?+
GPTBot (OpenAI), OAI-SearchBot (OpenAI), ClaudeBot (Anthropic), and PerplexityBot are the major AI crawlers that recognise llms.txt guidance. Bytespider (ByteDance) also follows the standard. Robots.txt handles crawler access while llms.txt handles content prioritisation. Use both files together for the strongest AI search visibility. This generator outputs a file compatible with all major AI crawlers.
Where do I upload the llms.txt file?+
Place llms.txt at your domain root so it is accessible at https://yourdomain.com/llms.txt. On WordPress, upload via FTP to the public_html folder or use a file manager plugin. The file must be publicly accessible without redirects or authentication. Some WordPress security plugins block .txt files at the root; whitelist the filename in your plugin settings if that occurs.
How is llms.txt different from robots.txt?+
Robots.txt controls whether crawlers can access a URL at all. llms.txt guides AI language models on which content is most relevant and how to use it. Think of robots.txt as a gate and llms.txt as a signpost. Blocking a page in robots.txt prevents crawling; listing it in llms.txt signals its importance for AI citation. The two files serve entirely different purposes and neither replaces the other.
Does llms.txt improve Google AI Overviews visibility?+
Google has not officially confirmed it reads llms.txt for AI Overviews. However, the structured content guidance it provides aligns with how Google AI systems evaluate page importance. Sites with clear content hierarchies and well-labelled priority pages tend to earn more AI Overview citations. Using llms.txt alongside strong schema markup, FAQ sections, and fast page speeds creates the best foundation for AI citation across Google, ChatGPT, and Perplexity.
How often should I update my llms.txt file?+
Update your llms.txt whenever you publish significant new content, restructure your site, or retire important pages. A quarterly review is a reasonable minimum for most sites. High-frequency publishers should update monthly. Out-of-date llms.txt files that reference deleted pages can confuse AI crawlers and reduce citation accuracy. Regenerate using this free tool after any major content audit or site migration.
Is the llms.txt standard officially approved?+
The llms.txt standard is a community-driven specification, not an official W3C or IETF standard as of 2025. It was proposed by Answer.AI and has been voluntarily adopted by a growing number of websites and AI platforms. Major AI labs have not rejected the format, and several crawlers already act on its guidance. The standard continues to evolve, so using a tool that generates up-to-date, correctly formatted output is important for compatibility.
