Put your product attributes in the fields AI actually receives: the Merchant Center feed for Google, the Shopify catalog for ChatGPT. 

The purchase then closes on your own checkout, since in March 2026 OpenAI [chose to leave payment to the stores](https://www.digitalcommerce360.com/2026/03/24/openai-agentic-commerce-updates-chatgpt-walmart/?ref=conversion.club). So the job looks much more like back-office housekeeping than an AI project.

## The benchmark

The source of the products ChatGPT recommends changed in a single day, without warning. In March 2026, [Peec AI](https://peec.ai/blog/how-ecommerce-managers-can-optimize-chatgpt-product-rankings-step-by-step?ref=conversion.club) found 83% of the roughly 43,000 products it tracked in the assistant's carousels among the top 40 free results on Google Shopping. 

On July 10, [Profound](https://www.tryprofound.com/blog/chatgpt-5.6-shopping-transformation?ref=conversion.club) saw the share of recommendations drawn from an integrated feed jump from 8% to 62%. These figures come from two tool vendors, each based on the queries it tracks. So you have two pipes to keep clean: Google's and Shopify's.

## The rule

Prepare your data now, even if you only sell in France. [Shopify's ChatGPT channel](https://help.shopify.com/fr/manual/online-sales-channels/agentic-storefronts/chatgpt?ref=conversion.club) requires you to [sell to customers in the United States](https://conversion.club/selling-internationally-on-shopify-the-checkout-guide/). 

Direct checkout in [Google AI Mode](https://help.shopify.com/fr/manual/online-sales-channels/agentic-storefronts/google?ref=conversion.club) also requires a store based there, and it doesn't show for anyone in France. Your products can still be found through [web crawling](https://conversion.club/playbook/does-an-online-store-need-an-llms-txt-file/) and through the feeds you share with Google, [Shopify says](https://help.shopify.com/fr/manual/online-sales-channels/agentic-storefronts/products?ref=conversion.club).

In a workshop, the manager who edits product pages for a ready-to-wear brand wondered aloud whether to keep creating custom fields: 

> "All the fields that showed up as suggestions in Shopify by default, I figure they must already be pre-optimized for AI \[...\] and we don't use them today." 

Our reading of the documentation supports her view: Shopify says it passes along the title, description, options, images, price and availability by default, and its list doesn't mention any custom field.

## The steps

1. Channels. On eligible stores, [Shopify turned on its agentic storefronts by default](https://www.shopify.com/news/agentic-commerce-momentum?ref=conversion.club) on March 24, 2026\. In Sales channels > Agentic, check the setting that lets Shopify manage channels for you: it also enrolls you in future ones. Each channel requires your three policies (terms of service, privacy, returns and refunds), which you complete in Settings > Policies.
2. Free listings. In Merchant Center, check for products rejected from free listings, not just those in campaigns. Titles, images, GTINs and prices follow the rules of [the Google Shopping listing](https://conversion.club/playbook/how-do-i-optimize-my-product-page-for-google-shopping/).
3. Locked-in attributes. Material or capacity often sits in metafields, tag prefixes or title separators. In Sales channels > Agentic, under Sources, [the mapping](https://help.shopify.com/fr/manual/shopify-catalog/mapping?ref=conversion.club) tells Shopify where to read the title, description and category. In our view, [everything else should go back into the description or the options](https://conversion.club/e-commerce-product-pages-how-to-write-for-humans-and-ai-agents/).
4. Conversational attributes. For your best sellers, fill in in Merchant Center [the ones Google designates for its AI surfaces](https://support.google.com/merchants/answer/17085370?hl=fr&ref=conversion.club), starting with `question_and_answer` and `related_product` (accessories, substitutes).
5. Exclusions. Shopify filters out B2B-only products: B2B catalogs, pages visible only after login, password-protected stores. Make sure no consumer item is hiding behind an account.

Step 3 is the most thankless. In a recent audit of another clothing brand, we counted more than two hundred product page templates, most of which differed only in their content: the text was written into the theme, outside the product data. 

We estimated the cleanup at about thirty hours.

## The trap

Guides age faster than catalogs, and ours do too: [the one we updated in February](https://conversion.club/how-to-get-your-shopify-store-ready-for-agentic-commerce/) still describes [agentic storefronts](https://conversion.club/agentic-commerce-how-do-you-sell-to-a-robot-that-doesn-t-care-about-your-branding/) as "not yet available in France." 

Others, dated fall 2025, show a buy button in the conversation that a Shopify store can no longer turn on. 

The funnel where the buyer lands is still [your checkout, opened in the built-in browser](https://conversion.club/playbook/does-chatgpt-traffic-convert-better-and-how-do-you-welcome-it/) of the ChatGPT mobile app. 

Test it there, looking for the consent banner that covers the page or [the cart that requires an account](https://conversion.club/playbook/should-you-require-account-creation-before-purchase/).

## The line to present

Take your ten best sellers and, for each one, look for [the attribute that decides the purchase](https://conversion.club/playbook/how-to-structure-a-product-page-so-ai-cites-it/), material for example, in the title, description and options. 

If it appears only in a template or a custom field, count it as missing. Then copy this sentence for your leadership team, rewriting it with your own count (the numbers below are made up):

> "Of our ten best sellers, six have their material in a field that neither Google nor ChatGPT receives. Putting it back into the product data takes two days, and that work also helps our Google Shopping listings, whether or not AI payment comes to France."
