By 2025, searching online isn’t just about Google’s familiar blue links anymore. Now, search is dominated by AI models — like ChatGPT, Gemini, and Claude — that scan the web, gather information directly from websites, and deliver it instantly as summaries, answers, or conversations.
For business owners and website managers, this shift brings a new challenge: How can you make sure AI systems interpret your website correctly? And how do you stay visible when users may never actually visit your site?
One of the newest tools that can help is something called the llms.txt file. It’s easy to create, but it can have a big impact on how AI finds and uses your content. Here’s what you need to know — and how to use it effectively.
What Is llms.txt?
The llms.txt file is a plain text document that you place in your website’s root directory — similar to a robots.txt file. But instead of communicating with traditional search engines like Googlebot, this file speaks directly to large language models (LLMs) — the AI systems behind tools like ChatGPT, Google’s Bard/Gemini, Bing Chat, and others.
Think of it as a custom roadmap for AI. It tells these systems what parts of your site matter most, which areas to avoid, and how you want them to credit your content when it’s used in AI-generated responses.
It’s essentially a blueprint that helps AI tools better represent your brand and content.
Why Is llms.txt Important Right Now?
AI-powered search isn’t a passing trend — it’s becoming the new standard.
These days, people ask questions directly in AI tools and get answers immediately — without ever seeing a list of links. These AI models decide what to pull from your site, whether to credit you, and how to quote your content. If you don’t provide guidance, they might pull outdated info, miss your best work, or skip over you completely.
By adding a llms.txt file, you take control. You help AI understand your most important content and display it in a way that works in your favor. As more AI-based search engines appear, this file could be just as essential to your strategy as SEO was a decade ago.
How Is llms.txt Different from robots.txt?
At first glance, llms.txt may seem like robots.txt, but they serve different purposes.
- robots.txt talks to traditional search engine bots and tells them what pages to index or ignore.
- llms.txt is for AI models. It helps them know what to summarize, quote, or ignore — and how to properly credit you.
So while robots.txt controls how search engines crawl your site, llms.txt controls how AI systems understand and share your content.
How to Create and Use a llms.txt File
Creating a llms.txt file is simple:
- Open a plain text editor like Notepad or VS Code.
- Create a file named
llms.txt. - Add rules that tell AI systems what content to include, what to skip, and how to attribute you.
Example:
User-Agent: * Allow: /blog/ Allow: /guides/ Disallow: /checkout/ Disallow: /private/ Attribution: https://yourwebsite.com/ Sitemap: https://yourwebsite.com/sitemap.xml
Once you’ve written your rules, upload the file to your website’s root directory, so it’s located at:
https://yourwebsite.com/llms.txt
AI tools will automatically discover and read it — just like search engines do with robots.txt.
Best Practices for Writing llms.txt
- Highlight your strongest content: Blog posts, guides, research, case studies, or how-to articles.
- Block private or sensitive areas: Avoid letting AI quote checkout pages or internal employee bios.
- Include attribution: This helps AI credit your site properly and drive traffic back to you.
What Happens If You Skip llms.txt?
Not using llms.txt won’t stop AI from crawling your site. But without guidance, it may pull the wrong content, overlook your best work, or misrepresent your brand.
In today’s AI-powered internet, first impressions matter — and letting AI misinterpret your site is a risk you probably can’t afford.
