What you get free
  • Valid llms.txt preview with brand summary and top auto-detected categories
  • Detection of whether you already publish llms.txt at /llms.txt
  • Top 3 findings (the rest unlock with email, plus the full copyable file)

How it works

  1. Paste your Shopify storefront URL. The generator reads your sitemap and your top collections to build an initial structure.
  2. Add a brand description (optional). A one-paragraph brand summary. If left blank, the generator infers one from the homepage, meta description, and about page.
  3. Review and edit the draft. The output includes brand summary, top collections, flagship products, guides, and policies. Edit descriptions to match brand voice before shipping.
  4. Copy, download, or host via Shopify redirect. Use the in-tool instructions to upload the file to Shopify Files and add a URL redirect from /llms.txt.

Sample output

Here is an example llms.txt for a fictional Pacific Northwest apparel brand. The tool outputs this kind of file, structured per the llmstxt.org proposal.

What the data means

Every entry in the generated llms.txt has three parts: URL, short label, and one-sentence description. The tool picks URLs from your sitemap and ranks them using homepage link prominence, sitemap priority, and collection depth. Descriptions are drafted from PDP titles, meta descriptions, and schema where available. Shopify-standard pages (policies, contact, about) are included automatically.

The validator runs four checks: the file is under 50 links per section, every URL responds with a 200 status code, Content-Type is plain text or markdown, and there is no redirect loop. Green indicators mean the file is ready to host; yellow flags mean a recommended manual edit; red means a blocker.

Why eCommerce Insights built this

Hand-authoring llms.txt for a Shopify store means scrolling Shopify admin, copying URLs, and writing descriptions by hand. It takes 60 to 90 minutes for a mid-sized catalog. The generator does the scroll-and-copy work in 30 seconds, then asks for voice edits where a human should decide.

Free tools like this exist because the eCommerce Insights team thinks healthy AI crawling behavior benefits every Shopify merchant, not just customers. A good llms.txt is foundational; it is not a product feature. The full eCommerce Insights product regenerates the file weekly and validates it against live crawler logs.

Keep it in sync

Regenerate automatically as your catalog changes.

The free generator produces a file now. The full eCommerce Insights product regenerates it weekly, revalidates every link, and monitors crawler-log fetches from GPTBot, PerplexityBot, and ClaudeBot. Paired with SKU tracking, PDP scoring, and push-to-Shopify.

Frequently asked questions

What is llms.txt and why would a Shopify store need one?
llms.txt is a plain-text, Markdown file served at the domain root that gives AI crawlers a curated map of your site. It sits alongside robots.txt and sitemap.xml but serves a different job — pointing at the pages that actually describe your brand and flagship catalog. Shopify stores benefit because default sitemaps expose every URL, which gives AI crawlers no priority signal.
Does an llms.txt improve my AI visibility?
eCommerce Insights' crawler log observations across hundreds of Shopify stores show that GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, and Google-Extended do fetch the file on sites that publish one. Adoption is advisory, not binding. The file alone will not win citations, but in combination with solid schema and PDP content it gives AI crawlers a cleaner read of the catalog.
Where do I install llms.txt on a Shopify store?
Shopify does not natively serve arbitrary files at the domain root. Upload the generated llms.txt to Settings → Files in Shopify admin, copy the CDN URL, then add a URL redirect under Online Store → Navigation → URL Redirects from /llms.txt to that CDN URL. A Cloudflare or edge-worker rewrite is a cleaner alternative if you already have a front door.
How often should I update my llms.txt?
After significant catalog changes — a new collection, a discontinued hero SKU, or a major policy rewrite. Monthly is a reasonable baseline for active merchants. Small product additions do not require an update. The file is a curated map, not an index, so big structural changes matter more than churn.
