How to Add llms.txt to Your Webflow Site

You can upload an llms.txt file to your Webflow site’s root domain on your custom domain. This file gives LLMs a structured overview of your site and may help them represent your content more accurately.

Note: The llms.txt format is an experimental convention — not yet widely adopted. It doesn’t guarantee your site will be read by LLMs, but it’s being explored as a way to provide signals. Learn more at llmstxt.org.

What is llms.txt?

Think of llms.txt as a proposed convention — like an early sitemap — but still experimental. It’s a structured plain-text file that gives LLMs a curated overview of your site’s content and how you want it interpreted.

Unlike sitemaps (which guide search engine crawlers), the intent is to help LLMs reason about your content, better summarize it, and surface relevant information when users ask questions. Current impact is not proven.

Will this improve my AI rankings?

Possibly, but the impact is unclear. Think of it like robots.txt in its earliest days.

How to upload an llms.txt file in Webflow

To upload your llms.txt file in Webflow:

Go to Site settings > SEO > LLMs.txt
Click Upload file
Choose your llms.txt file (must be UTF-8 encoded and under 100 KB)
Click Save changes

After publishing your site, the file will be available at https://example.com/llms.txt. Note that it won’t be published to your Webflow staging domain.

Writing your llms.txt file

The llms.txt format is actively evolving. We recommend following the official specification and checking back often for updates.

Here are some foundational best practices:

Use clear structure

Your file should be structured using titles and sections. Here’s a simplified example:

# Title
> Optional description goes here

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

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

Think like a prompt writer

LLMs don’t just parse — they interpret. Your llms.txt should feel more like a well-written instruction to a helpful assistant than a dense marketing deck. That means:

Avoid abstract jargon like “cutting-edge solutions for everyone.” Say what your product actually does.
Include examples and links with clear, short descriptions
Give the LLM enough context to correctly connect your content to related concepts

Pro tip: Write your llms.txt like you’re guiding a company intern who’s never seen your site before but is trying to describe your business accurately to someone else.

Don’t copy-paste your marketing content

Avoid pasting your homepage hero text verbatim. Instead, distill the core messages and describe your products or services plainly and specifically.

Best practices

Keep the file under 100 KB, UTF-8 encoded
Update it regularly as your site changes
Curate the content — don’t include internal or sensitive URLs
Don’t rely on llms.txt as your only method to reach LLMs — think of it as one helpful signal
