What is a BigCommerceLLMs.txt file?
An LLMs.txt file is a plain-text markdown file hosted at your store root, at yourstore.com/llms.txt. It hands AI models a clean, prioritized map of your catalog: your best categories, key products, brands, and policies. Instead of parsing your theme, apps, and scripts, AI reads a simple summary of what you sell, in your own words.
- Maps your categories, products, and brands for AI
- Plain-text markdown, spec-compliant format
- Served at yourstore.com/llms.txt
- You decide which products AI should prioritize
Built for AI understanding
A machine-readable overview of your store, so AI tools can find, understand, and recommend the right products.
llms.txt vs robots.txt vs sitemap.xml on BigCommerce
Your BigCommerce store already uses several of these files. They do different jobs and work best together.
| File | What it does on your store | Who it is for | Status on BigCommerce |
|---|---|---|---|
| robots.txt | Controls which store URLs crawlers can access | All crawlers | Editable in admin |
| sitemap.xml | Lists your product, category, and page URLs | Search engines | Auto-generated |
| llms.txt | A clear summary of your store so AI understands your catalog faster | AI models and agents | Recommended |
| Product schema | Machine-readable price, availability, and review data | Search engines + AI | Proven |
llms.txt vs Product schema: which moves your store's AI visibility?
Do both. An llms.txt is a quick win you control. Product and Offer schema is what Google and AI already read to verify your prices, stock, and ratings.
llms.txt Emerging
A lightweight summary of your store. Quick to publish and a clean map for AI, but not yet a confirmed ranking or recommendation signal for major AI engines.
- Takes minutes, no app needed
- You pick which categories to highlight
- Low risk, low cost
Product schema Proven
JSON-LD Product, Offer, and Review schema is documented by Google and used by AI to verify your catalog. It powers rich results in search today.
- Drives price, rating, and stock rich results
- Rakuten saw 1.5x longer sessions with structured data
- Verified by Google case studies
Why your BigCommerce store needs an llms.txt
Control how AI describes your products
Tell ChatGPT and Gemini what you sell instead of letting them guess from theme markup and app code.
Cut through store-page clutter
Storefronts carry heavy themes, scripts, and apps. A clean text map is far easier for AI to read than your rendered pages.
Point AI to your best categories
Surface your hero categories and high-margin products, not cart, checkout, or account pages.
Future-proof for AI shopping
As AI shopping assistants grow, your store already speaks their language with a clean catalog summary.
What a BigCommerce llms.txt file looks like
An H1 with your store name is the only required line. Sections for categories, products, and pages add the context AI needs.

How to host your llms.txt file on BigCommerce
BigCommerce does not give you direct root access, so you upload the file over WebDAV and point a redirect at it. It takes about ten minutes.
The WebDAV + redirect method
- Generate and download your file, then open
Settings > File Access (WebDAV)in your store admin and uploadllms.txtto a web-accessible folder. - Go to
Server Settings > 301 Redirectsand create a redirect from/llms.txtto that file's URL, or use an app that creates the redirect for you. - Visit
yourstore.com/llms.txtin a browser and confirm it returns plain text and a 200.
Prefer full control over the response? Serve /llms.txt from a CDN or reverse proxy, such as a Cloudflare Worker, placed in front of your store domain.
