How to generate an llms.txt for your Shopify store.

How people do this without eCommerce Insights

The manual version of this job takes an afternoon if you've done it before and most of a day if you haven't. You scroll Shopify admin looking for a "root files" section that does not exist. You read the llmstxt.org proposal and understand the format. You open a text editor and start copy-pasting URLs from your Shopify admin — your top 20 collections, your top 50 products, your guides, your policies. You write a one-sentence description for each one.

Now you need to host it. You search "how to host llms.txt on Shopify" and find three different answers: use a Shopify app, use a redirect, use a theme hack. You pick the redirect path, upload the file to Files, copy the CDN URL, add the redirect, test in a private browser window. It works. You close the tab and move on to the next thing.

Two months later someone asks if the file is up to date. It is not. You launched three new collections since then. The file still references a discontinued SKU. You need to do the whole thing again. That's the real problem with llms.txt — not the initial setup, the maintenance.

How to do this in eCommerce Insights

1. Generate a draft with the free tool. Open eCommerce Insights's free llms.txt generator, paste your Shopify storefront URL, and get a draft in 30 seconds. The tool reads your sitemap, your collection structure, and your homepage links to pick the 40-80 URLs that actually matter for AI crawlers.
2. Edit descriptions to match brand voice. The generator drafts descriptions from your meta descriptions, PDP titles, and schema. They are accurate but generic. Spend ten minutes tightening the ones that matter — your hero products and top collections — so they match how your brand actually talks.
3. Upload to Shopify Files and add a URL redirect. Copy the final file. In Shopify admin, go to Settings → Files and upload. Copy the resulting Shopify CDN URL. Then open Online Store → Navigation → URL Redirects and add a redirect from /llms.txt to that CDN URL. Save.
4. Validate the live file. Open yourdomain.com/llms.txt in a private browser window. Confirm it loads as plain text (not wrapped in the Shopify theme), the Content-Type header is plain text or markdown, there's no redirect chain, and every listed URL responds 200 when clicked. eCommerce Insights's generator includes a built-in validator that runs these checks in one pass.
5. Set a regeneration cadence. Free: monthly, manually. Paid: eCommerce Insights regenerates weekly, monitors crawler-log fetches for GPTBot, PerplexityBot, and ClaudeBot, and flags when the file has gone stale (new collections added, hero SKUs discontinued). Either cadence beats the hand-maintained file that goes stale.

What "good" looks like

• A live /llms.txt returning 200 with plain-text Content-Type. No theme wrapper, no redirect chain, no 404.
• 40-80 entries total, covering the homepage, about, top 10 collections, top 20 PDPs, top guides, policies, and contact. No draft or archived products.
• Descriptions that read like Wikipedia summaries: accurate, specific, no marketing superlatives. "The Founder Parka: 650-fill down, waterproof shell, unisex sizing, $485" beats "our industry-leading outerwear."
• Weekly crawler-log hits from at least three AI bots: GPTBot, PerplexityBot, ClaudeBot are the baseline expectation for stores with a published file.
• Monthly or weekly regeneration. Any cadence faster than ad-hoc manual updates.
