How to Add LLMs.txt File to Webflow for AI Optimization (2025 Guide)

Table of content

In the fast-growing world of AI, websites are no longer just built for humans. They are also being scanned, read, and learned from by powerful Large Language Models (LLMs) like ChatGPT, Google Gemini, Claude, and more. These AI models constantly crawl the internet, taking in publicly available content to train their algorithms and improve how they interact with users.

For Webflow designers, marketers, agencies, and SaaS founders, there is an important question: How much of your website’s content should AI models be allowed to access and learn from?

The answer is the LLMs.text file. This is a new text file that gives you control over whether and how your content is used by these AI systems or models. If you're building a new website on Webflow in 2025, understanding and implementing LLMs.txt is not just optional; it's a smart step toward protecting your content and managing your digital footprint.

In this guide, we’ll break down what LLMs.txt is, how to add it to your Webflow project, and what it means for the future of web privacy and AI.

What is LLMs.txt?

LLMs.txt is a plain-text file placed in the root directory of your website (like yourdomain.com/llms.txt). Its purpose is to tell AI crawlers whether or not they are allowed to access your website's content.

This is similar in concept to the traditional robots.txt file, which communicates rules to search engine bots. But instead of guiding how content appears in search results, LLMs.txt gives you control over whether your content is used to train generative AI models.

Why LLMs.txt Matters for Your Website

1. Helps Control AI Data Usage

LLMs.txt allows you to choose if and how AI models access your content. Whether you're a blogger, SaaS founder, agency, or eCommerce brand, this control helps:

  • Prevent AI from using your unique or sensitive content.
  • Limit the risk of your information being copied in chatbot responses.
  • Customize permissions for different bots.

2. Enhances Privacy and Content Protection

AI models scrape billions of web pages, including personal blogs, product pages, documentation, case studies, and more. Without controls like LLMs.txt, you have no say in how that data is used.

Adding LLMs.txt helps you:

  • Avoid content theft or misuse by AI platforms.
  • Protect intellectual property.
  • Signal boundaries for LLM usage.

3. SEO Implications: Does It Affect Rankings?

No, LLMs.txt does not affect your SEO rankings in Google or Bing.

It only controls whether your content can be used to educate AI models, not whether it can be indexed in search results. That’s still governed by robots.txt and meta tags like noindex.

4. Transparency for AI Indexing

Just like robots.txt made crawling transparent for search engines, LLMs.txt offers similar transparency for generative AI. It’s a step toward more ethical AI development where creators and site owners are respected.

How to Add LLMs.txt to Webflow

Webflow doesn’t let you directly access the root folder, but with a few clever workarounds, you can still host and configure an LLMs.txt file on your domain. Here's how:

Step 1: Create the /llms.txt File

Use any text editor (Notepad, VS Code, Sublime Text) to create a file named llms.txt. Add your desired rules.

Create the content for your /llms.txt file. This file should contain information about your website that LLMs can use, such as page titles, some descriptions, and links.

Example:

# Title

> Optional description goes here

Optional details go here

## Section name

- [Link title](https://link_url): Optional link details

## Optional

- [Link title](https://link_url)

Step 2: Upload to Webflow Assets

In your Webflow project dashboard:

  • Go to Assets panel
  • Click Upload
  • Upload your llms.txt file

Webflow will now host your file at a unique URL like https://yourdomain.com/assets/llms.txt.

Step 3: Get the Asset URL

After uploading, click the file and copy its full public URL. You’ll use this in the next step to redirect AI bots to your file.

Step 4: Create the 301 Redirect

Webflow doesn’t allow root-level .txt files, but you can simulate it with a redirect.

Access your project settings by clicking the gear icon in the Webflow Designer. Navigate to the Publishing tab and scroll down to locate the Redirects section.

Click Add Redirect to create a new redirect rule. In the Old Path field, enter ‘/llms.txt’ exactly as shown in the screenshot. In the Redirect to field, paste the complete CDN URL you copied in the previous step.

Step 5: Redirect Configuration

Click Save Changes, then publish your site again to ensure the redirect goes live.

Double-check by visiting https://yourdomain.com/llms.txt. If it loads correctly, the setup is complete.

Step 6: Publish and Test

After publishing your site:

  • Visit yourdomain.com/llms.txt to confirm the redirect
  • Use browser dev tools to inspect the HTTP status code (should be 301)
  • Test using bots or SEO tools to confirm accessibility

Future of LLMs.txt in AI and Web Privacy

The introduction of LLMs.txt in 2024–2025 marks a critical turning point in the relationship between AI systems and content creators.

Evolving Standards for AI Crawling

As AI regulation gets global traction, LLMs.txt is growing as a de facto standard for ethical AI scraping. Similar to how robots.txt became a best practice for SEO, we anticipate:

  • Widespread adoption among AI companies
  • More granular options (e.g., time-limited access, content types)
  • Regulatory requirements for AI bots to respect LLMs.txt

Role in Future SEO and Content Control

While LLMs.txt doesn’t affect rankings, it gives you strategic control over what content fuels the next generation of AI chatbots.

This is vital for:

  • Thought leaders and educators protecting IP
  • SaaS companies avoiding content leakage
  • Brands maintaining message consistency

Expect CMS platforms, SEO tools, and AI monitoring services to begin integrating LLMs.txt as a standard configuration.

Conclusion

In a world where AI is reading everything, LLMs.txt is your voice of consent. It’s a small file with a big role, one that every modern website, including those built on Webflow, should consider implementing.

Here’s a quick recap:

  • LLMs.txt lets you control which AI models can access your website.
  • It’s similar to robots.txt but designed for generative AI like ChatGPT, Gemini, and Claude.
  • Webflow users can add it using the Asset Manager + 301 Redirect method.
  • It doesn’t impact SEO but strengthens content privacy and brand protection.

As AI tools grow smarter, the websites they learn from must grow wiser. Adding an LLMs.txt file today helps shape a more responsible AI-driven web tomorrow.
