Why Every Business Website Should Add an llms.txt File—Especially Now with Webflow’s Native Support

In today’s AI-driven world, your website isn’t just for people anymore—it’s also for machines. Specifically, large language models (LLMs) like ChatGPT, Claude, and Gemini are constantly scanning the web to learn from and surface information to millions of users. That means your content may be feeding these AI tools—whether you realize it or not.

So how do you, as a business owner, control how your content is accessed and used by these models?

Enter: llms.txt.

What Is llms.txt?

Think of llms.txt as the modern-day equivalent of robots.txt—but for AI models. While robots.txt tells search engines what they can and can’t crawl, llms.txt does the same for large language models.

By adding this simple text file to your site, you can:

• Choose which AI models are allowed to crawl your content
• Opt out of having your site data used to train or inform LLMs
• Ensure attribution and ethical usage when content is included
• Claim your space in the AI web ecosystem

What Happens If You Don’t Have It?

Without an llms.txt, your content is fair game. LLMs may crawl your site, use your content to inform AI answers, and present information about your brand—all without your knowledge or control.

Here’s what you risk:

• Loss of content ownership boundaries – Your carefully created blogs, product pages, and brand messaging may be reused without attribution.
• Reduced brand visibility – If your site isn’t clearly represented or crawled inconsistently, you may miss out on AI search exposure.
• Lack of control – You can’t say "yes" or "no" to different AI providers without this file in place.

Webflow Just Made It Easy

On April 8, 2025, Webflow announced native support for llms.txt, giving users the power to manage how AI interacts with their websites—without needing to touch code.

If your site is built on Webflow, you can now create and manage your llms.txt file directly through their interface. This puts powerful digital governance tools in the hands of every business, no technical team required.

Why You Should Act Now

AI is becoming the default interface for online discovery. If your content isn’t available to—or properly represented by—AI models, you're missing out on visibility and influence.

Adding an llms.txt file ensures:

✅ Your business is discoverable in AI-powered experiences
✅ You control how your content is used by third-party AI systems
✅ You align with emerging digital best practices around consent and content usage

Final Thoughts

Your content is an asset. llms.txt helps protect and position that asset in the evolving world of artificial intelligence.

If you’re a Webflow user, implementing this is now easier than ever. Take a few minutes today to set up your llms.txt—and take back control of how your content lives in the AI-powered web.
