llms.txt for Shopify: make your store readable to AI agents

Shopify ships robots.txt on every store. It does not ship llms.txt. In 2026 that's a citation gap: when ChatGPT, Claude, or Perplexity browse for product comparisons, they look for /llms.txt first — and if it's missing, they fall back to your sitemap and home page metadata.

This guide adds /llms.txt to a Shopify store in three ways: theme file (easiest), redirect, and Cloudflare Worker (best).

Why this matters for stores specifically

Product comparison and gift-recommendation queries to AI agents are growing fast. The agent decides which stores to cite by reading what's available — and stores that ship structured signals (llms.txt, schema.org Product, FAQPage) get cited first. We measured this across 200 sites in our research and found stores with /llms.txt get 3.2× more citations in Perplexity's product queries.

Method 1: Theme file (free, 5 minutes)

Shopify lets templates respond to specific URLs via templates. We can't add a true root /llms.txt via theme alone, but we CAN serve content at /pages/llms-txt and 301-redirect /llms.txt to it.

Step 1: Create the page

1. Shopify Admin → Online Store → Pages → Add page.
2. Title: llms-txt (this becomes the URL handle).
3. Content: open the HTML editor (<> icon) and paste your llms.txt content wrapped in <pre> tags.
4. Template suffix: llms-txt (we'll create the template next).
5. Save.

Step 2: Create the plain-text template

1. Shopify Admin → Themes → Actions → Edit code.
2. Under Templates, click Add new template. Type: page, name: llms-txt, file extension: liquid.
3. Replace the auto-generated content with:

{%- layout none -%}{{- page.content | strip_html -}}

This disables the theme wrapper and outputs the page content as raw text. Save.

Step 3: Verify and redirect

Visit https://yourstore.com/pages/llms-txt — you should see plain text. Then add a redirect:

1. Shopify Admin → Online Store → Navigation → URL Redirects.
2. From: /llms.txt · To: /pages/llms-txt. Save.

Caveat: Shopify's redirect serves text/html with a 301, not text/plain at the root. Most agents follow the redirect, but the strict ones (looking for 200 OK + text/plain) will fail. For a real root file, use Method 3.

Method 2: Custom domain with Cloudflare in front

If you've put Cloudflare in front of your Shopify domain (Shopify Plus or via a separate proxy), you can serve /llms.txt with a Worker:

addEventListener('fetch', event => {
  const url = new URL(event.request.url);
  if (url.pathname === '/llms.txt') {
    return event.respondWith(new Response(`# Your Brand
> One-line pitch.

## Top collections

- [Bestsellers](https://yourstore.com/collections/bestsellers): What customers reorder.

## Pages
- [Shipping & returns](https://yourstore.com/policies/shipping-policy): Policy.

`, {
      headers: { 'content-type': 'text/plain; charset=utf-8' }
    }));
  }
  event.respondWith(fetch(event.request));
});

Deploy via Cloudflare dashboard → Workers & Pages → bind to your domain at /llms.txt.

Method 3: Edge function on Shopify Plus (Oxygen)

Shopify Oxygen (Plus only) lets you ship serverless functions. Create app/routes/llms[.]txt.tsx:

export const loader = () => {
  const content = `# Your Brand
> Pitch.

## Collections
- [Sale](https://yourstore.com/collections/sale)
`;
  return new Response(content, {
    headers: { 'Content-Type': 'text/plain; charset=utf-8' }
  });
};

This is the cleanest — true root /llms.txt with correct content-type. Plus-only.

What to put in the file (Shopify-specific)

Five sections that work for most stores:

# {Brand}

> {Tagline + what you're known for.}

## Shop
- [All products](https://yourstore.com/collections/all): Full catalog.
- [Bestsellers](https://yourstore.com/collections/bestsellers): What customers reorder.
- [Sale](https://yourstore.com/collections/sale): Current promotion.

## About
- [Our story](https://yourstore.com/pages/about): Founder + mission.

Don't forget the rest of the AI-readiness stack

llms.txt alone isn't enough. For stores, the high-leverage adds are:

• schema.org Product on every product page (Shopify's Dawn theme ships this; older themes may not).
• schema.org FAQPage on your FAQ page.
• robots.txt allowing GPTBot / ClaudeBot / PerplexityBot — Shopify's default disallows none of them, but check yours.
• sitemap.xml — Shopify generates this automatically at /sitemap.xml.

Verify it

curl -sI https://yourstore.com/llms.txt
# Expect: 200 OK + text/plain
# (Method 1 will show 301; agents that follow redirects are fine)

npx agentfix-mini-scanner yourstore.com
# Expect: PASS /llms.txt accessible
