Shopify Catalog is the system that structures your product data and sends it to AI channels such as ChatGPT and Microsoft Copilot. If your store is eligible, your products are in it by default.
Google and Meta take a different route, and that detail trips people up. This guide covers how Catalog works, how to check your status and how to opt out. It is part of our Agentic Commerce hub, and was checked against Shopify's documentation on 9 November 2026.
Key Takeaways
- Shopify says eligible products are listed in Shopify Catalog by default, with nothing to configure.
- ChatGPT and Microsoft Copilot find products through Catalog. Google AI Mode, Gemini and Meta use separate sales channels.
- You can see your eligibility under Sales channels > Agentic in your Shopify admin.
- Blocking AI crawlers does not stop Catalog from sending your product data to channels you've activated.
- Turning off Catalog access can take up to 7 days to take effect, and your products can still be found through other routes.
- Being in Catalog does not guarantee an AI channel will show your products.
What Shopify Catalog is
Shopify's June 2026 guide to agentic commerce defines it. "Shopify Catalog is the structured data layer that makes products readable to AI agents."
An AI agent can read a web page, but a page mixes product facts with design and navigation. Catalog sends the facts in a consistent format instead.
Shopify's Catalog page says the index holds "Over 1 billion products from millions of merchants on Shopify." That is Shopify's own figure.
How your product data reaches AI channels
Shopify's agentic storefronts page says your products reach AI channels through Shopify Catalog, or through Google's channels for AI Mode and Gemini.
The route depends on the channel:
| AI channel | How it gets your products | How the buyer checks out |
|---|---|---|
| ChatGPT | Shopify Catalog | On your online store checkout, in an in-app browser or a new tab |
| Microsoft Copilot | Shopify Catalog | Shopify-powered direct checkout if you have it active |
| Google AI Mode and Gemini | Google & YouTube sales channel or Merchant Center | Shopify-powered direct checkout if you have it active |
| Meta surfaces | Facebook and Instagram by Meta sales channel | Shopify-powered direct checkout if you have it active |
Shopify adds a note on Google. "Direct checkout is also rolling out to Google users and might not yet be available in your store."
Shopify also says agentic storefronts is active by default for eligible stores. To use it, you must agree to its supplemental terms of service.
What data Catalog sends
Shopify's Catalog and product discovery page lists what is sent by default. It includes title, description, options, images, price, availability and other key attributes.
Shopify adds: "Shopify Catalog continuously updates your product data, so AI channels receive your latest inventory and prices."
Shopify also says Catalog infers extra attributes using machine learning and transaction signals. Its example is a candle listed under home decor being identified as a popular Mother's Day gift.
How to check your status
Open Sales channels > Agentic in your Shopify admin and look at Sources > Shopify Catalog. Shopify says one of two things appears:
- If you're eligible, you'll see the number of products you have in Catalog.
- If you aren't, you'll see an Ineligible warning. Click it to read the reason.
An ineligible store has no products in Catalog. Shopify notes that AI channels might still find and show your products through other means, such as web crawling.
How to fix data that looks wrong
Shopify offers a Channel mapping page for data that doesn't sit in standard fields. Shopify says this helps stores with custom setups, such as metafields, tag prefixes or separators in product titles.
You can also group separate products that are really variants of one item, so they show as a single listing.
Check your compare-at prices too. Shopify says you can choose whether Catalog uses the price or the compare-at price as the list price. Agents might use the list price to show a strikethrough sale price.
The agentic admin page also lets you preview how products appear in Catalog search.
How rankings work
Shopify doesn't publish a formula. Its guide says "Ranking factors vary by AI platform but can include data quality, relevance, availability, pricing, and engagement signals."
So the practical work is plain data work. Write accurate titles, complete your attributes, and keep prices and stock correct. None of that guarantees a product will be shown.
Shopify's help page says that for accuracy and discoverability you should focus on complete, well-structured product information and on following SEO best practices.
Crawlers, robots.txt and Catalog are separate
Your robots.txt file and Catalog are two different pipes, and blocking one does not close the other.
Shopify's help page states: "Blocking AI crawlers at the /robots.txt or network layer affects only open-web discoverability. It doesn't stop your product data from being sent by Shopify Catalog to the agentic storefronts that you've activated."
Shopify also describes the limit of those rules. "The rules that you set in your /robots.txt file are directional and advisory, and not all crawlers are guaranteed to follow them."
agents.md and llms.txt are not Catalog either
Shopify says every store automatically serves /agents.md, /llms.txt and /llms-full.txt. These files describe your store's name, policies and discovery endpoints.
Shopify is clear about which one matters for product data. "Shopify Catalog is the authoritative product data feed to your agentic channels." The discovery files are separate and don't replace it.
How to opt out
You have three levels of control, and each does something different.
| Action | What it does | The limit |
|---|---|---|
| Turn off Catalog access for a channel | Stops sharing with that channel | Products may still appear through other discovery methods |
| Turn off Catalog access entirely | Stops sharing with all third-party agentic storefronts and also deactivates direct checkout | Shopify says it can take up to 7 days, and your products stay on Shop |
| Set a product to Unlisted | Hides it from AI channels | Also hides it from sitemaps, search engines and your store search |
To change channels individually, turn off the "Allow Shopify to manage for me" setting. Leaving it on means you're automatically enrolled in future agentic storefronts.
Read the Unlisted caution carefully. Shopify warns that it also removes the product from Google and your own store search.
B2B and wholesale products
One limit matters here. "Shopify's agentic storefronts support only direct-to-consumer (D2C) sales." Shopify says products sold only to business customers are excluded automatically, when Shopify can identify them.
Detection has gaps. Shopify might miss wholesale prices hidden by third-party apps or custom theme code. Those products might appear on AI channels.
Our Shopify B2B guide covers the native features.
If you sell the same product both ways, Shopify says it's included at your D2C price.
If you don't sell on Shopify
Shopify's Agentic plan is for merchants that don't already use Shopify as their ecommerce platform. Shopify says "The Agentic plan has no monthly subscription fee." Other fees might still apply, such as payment fees.
Direct checkout is deactivated by default on that plan.
Shopify's Catalog page also says that, in beta, Catalog includes products from brands that don't sell on Shopify. They are off by default, show only for US shoppers, and link to the brand's site.
For developers: two Catalog interfaces
If you build agents, Shopify's About Catalogs page describes two interfaces. Global Catalog searches across all Shopify merchants. Storefront Catalog covers one store.
Both implement the Universal Commerce Protocol catalog capability. Shopify's Global Catalog page has the tool details.

Frequently asked questions
Do I need to do anything to be in Shopify Catalog?
Shopify says eligible products are listed by default and there's nothing to configure. Check Sales channels > Agentic to confirm your store is eligible.
Does Shopify Catalog send my products to Google AI Mode?
No. Shopify says products reach Google AI Mode and Gemini through the Google & YouTube sales channel or Google Merchant Center.
Will blocking GPTBot in robots.txt remove me from ChatGPT?
Not through this route. Shopify says crawler blocks affect only open-web discovery. They don't stop Catalog sharing with channels you've activated.
How do I remove one product from AI channels?
Shopify says to set the product status to Unlisted. That also hides it from sitemaps, search engines and your own store search.
How long does opting out take?
Shopify says it can take up to 7 days after you turn off Catalog access. Your products may still appear through other discovery methods.
