In today’s AI-driven digital world, websites are no longer only optimized for human visitors and search engines—they’re also increasingly accessed by artificial intelligence tools like ChatGPT, Claude, Perplexity, and others. These large language models (LLMs) rely on data from across the web to train and generate helpful responses. But what happens when you want to control how your website content is used by these AI systems?
Enter llms.txt—a newly proposed file standard designed to help website owners control how AI crawlers interact with their content. Inspired by the long-standing robots.txt
file used to direct search engine bots, llms.txt
brings a new layer of transparency and governance specifically for LLMs.
For WordPress site owners, understanding and implementing llms.txt
can be a valuable step. Whether you’re a blogger, content creator, or SEO strategist, this simple text file gives you a voice in how AI tools engage with your web content.
In this guide, we’ll explore what llms.txt is, why it matters, and most importantly, how you can easily create and integrate it into your WordPress site—with or without technical experience. Let’s dive into the future of AI content accessibility and take control of how your digital assets are handled by the next generation of AI.
What is llms.txt?
The internet has long relied on standards like robots.txt
and sitemaps.xml
to communicate with search engines. These simple files instruct bots what they are allowed to crawl, index, or avoid. But as AI evolves, so do the types of bots that visit your site—especially large language models (LLMs) like ChatGPT, Claude, and Perplexity. To address this new wave of AI traffic, a new file format called llms.txt
has been proposed.
📌 The Origin of llms.txt
llms.txt
was proposed by Jeremy Howard, an Australian technologist and co-founder of fast.ai. Recognizing the need for AI-specific web crawling standards, Howard introduced llms.txt
as a way for content owners to declare how they want their data to be accessed—or restricted—by AI crawlers.
While still a community-driven proposal, it is gaining traction as more AI tools begin honoring its directives in the same way traditional search engines respect robots.txt
.
🛠️ How Does It Work?
The concept is straightforward. A website owner creates a plain text file named llms.txt
and places it at the root of their domain (e.g., https://yourwebsite.com/llms.txt
). Inside this file, you can add instructions for AI crawlers using standard directives such as:
vbnetCopyEditUser-Agent: gptbot
Disallow: /private/
Allow: /public-blog/
User-Agent
specifies the AI bot you’re addressing (likegptbot
for ChatGPT).Disallow
tells the bot which folders or pages it should not access.Allow
permits specific content to be crawled.
🆚 llms.txt vs robots.txt
Feature | robots.txt | llms.txt |
---|---|---|
Purpose | Manage search engine bot access | Manage AI/LLM crawler access |
Syntax | Similar | Almost identical |
User-Agents | Googlebot, Bingbot, etc. | gptbot, anthropic-ai, etc. |
Supported By | Search engines | LLMs (ChatGPT, Claude, Perplexity, etc.) |
Legal Binding | Not enforced, just a request | Also a request, no legal power (yet) |
Though both formats are structurally similar, their intended audiences differ significantly. robots.txt
is for search engines, while llms.txt
is tailored for AI crawlers and LLMs that process your content for training or delivery in chatbots.
🤖 Supported LLM Bots
As of now, several major AI systems have begun recognizing and respecting llms.txt
:
- gptbot – OpenAI (ChatGPT)
- anthropic-ai – Claude by Anthropic
- perplexitybot – Perplexity AI
- coherebot – Cohere
Expect this list to grow as the industry evolves.
Why Does llms.txt Matter?
As artificial intelligence continues to shape how users interact with information online, the importance of managing how your content is used has never been more critical. While robots.txt
has long served as a tool for webmasters to control search engine crawling, it does little to prevent AI systems from scraping or referencing your website data. That’s where llms.txt
steps in—giving you agency in the age of AI.
Let’s break down why llms.txt
matters and how it benefits website owners, digital marketers, and content creators alike.
🔒 1. Control Over Your Content
AI bots are increasingly crawling websites to train language models or generate responses for users. Without a clear directive, your content could be:
- Quoted in AI answers without attribution,
- Used in training datasets,
- Crawled repeatedly, straining your server resources.
With llms.txt
, you can clearly specify which content you want included or excluded from these processes. This provides a level of control similar to opting out of data tracking.
⚖️ 2. Supports Ethical AI Use
Many developers and companies behind LLMs are now committed to responsible AI practices. Just as they respect robots.txt
, they’re also starting to honor llms.txt
to avoid scraping or referencing data from websites that request not to be accessed.
Using llms.txt
allows you to participate in and influence the ethical use of AI technologies by clearly communicating your content policies.
⚙️ 3. Reduces Server Load from AI Crawlers
AI bots that scrape large amounts of data can increase the load on your server, especially if you run a high-traffic or content-rich WordPress site. By specifying Disallow
paths in llms.txt
, you can help prevent unnecessary crawling of pages like:
- Admin areas
- Checkout or payment pages
- Member-only content
- Multimedia-heavy directories
This helps preserve bandwidth and server performance, especially during traffic spikes.
🔍 4. Improved LLM Content Indexing
Ironically, allowing access to the right areas through llms.txt
can improve how your content appears in LLMs like ChatGPT or Perplexity. If you want AI bots to reference your content or summarize it accurately, guiding them to your best, most relevant pages can enhance visibility.
This is particularly helpful for:
- Blog posts
- Product guides
- FAQs
- Case studies
🧠 5. Stay Ahead of the SEO Curve
Search engines and AI are converging fast. Already, tools like Google SGE (Search Generative Experience) and Bing Copilot blur the lines between AI answers and traditional search results. Having llms.txt
in place shows you’re adapting to the next generation of content discovery and SEO.
It also demonstrates to users and clients that your site complies with evolving tech standards, increasing trust and credibility.
In short, llms.txt
isn’t just about blocking bots—it’s about choosing how AI interacts with your site, protecting your content, and positioning your WordPress site strategically in the future of the web.
IV. How Does llms.txt Work?
At its core, llms.txt
is a simple plain text file—just like robots.txt
—that you place at the root of your website. Its role is to tell AI crawlers (LLM bots) what they are allowed to access and what they should avoid. The file is publicly accessible (e.g., https://yourwebsite.com/llms.txt
) and can be read automatically by any bot that follows the proposed LLM access guidelines.
Let’s break down how it functions in practice.
🏗️ Structure of llms.txt
The file uses a very simple format. Each directive begins with a User-Agent, followed by Allow or Disallow instructions.
Here’s an example:
makefileCopyEditUser-Agent: gptbot
Disallow: /private/
Allow: /blog/
User-Agent: anthropic-ai
Disallow: /
Key Components:
Directive | Description |
---|---|
User-Agent | Refers to the specific LLM bot (like gptbot or anthropic-ai ) |
Allow | Tells the bot which directories/pages it can access |
Disallow | Tells the bot which directories/pages to avoid |
💡 Tip: Use *
as a wildcard to target all bots. For example:
makefileCopyEditUser-Agent: *
Disallow: /premium-content/
🤖 Common LLM Bot Names
AI Bot | User-Agent | Platform |
---|---|---|
OpenAI GPT | gptbot | ChatGPT |
Anthropic Claude | anthropic-ai | Claude |
Perplexity AI | perplexitybot | Perplexity |
Cohere | coherebot | Cohere AI |
These names are case-sensitive and must be written exactly as recognized by the respective platforms.
💬 Practical Scenarios
Let’s look at a few use cases:
✅ Allow all AI bots to access your public blog
makefileCopyEditUser-Agent: *
Allow: /blog/
Disallow: /
❌ Block GPTBot from crawling your entire site
makefileCopyEditUser-Agent: gptbot
Disallow: /
✅ Allow Perplexity to index your case studies, but block everything else
makefileCopyEditUser-Agent: perplexitybot
Allow: /case-studies/
Disallow: /
✅ Allow all bots full access
makefileCopyEditUser-Agent: *
Disallow:
This tells every bot it can freely access your entire site.
⚠️ Important Notes
- No enforcement: Just like
robots.txt
,llms.txt
is a guideline, not a hard rule. It’s up to AI companies to honor it. - Public file: Anyone can view your
llms.txt
file by visiting the URL. It’s not private. - No legal standing (yet): While it reflects your preferences, there’s no current law enforcing these instructions.
