AI shopping agents: get your checkout ready to sell

AI assistants are becoming a place where shoppers buy, not just where they search. Google's Universal Commerce Protocol (UCP) is an open standard that lets a shopper complete a purchase directly in AI Mode in Google Search or in Gemini, while your store stays the seller. Whether or not you join, the same rule applies: an agent can only sell what it can read clearly, and only send shoppers to a checkout that works.

What agentic checkout changes

In a classic journey, the shopper lands on your product page, adds to cart and pays on your site. With agentic checkout, the AI assistant finds the product, shows price and delivery, and the shopper confirms the order on the AI surface. According to Google's developer documentation, UCP uses your existing Merchant Center feeds, offers a native checkout integration by default and an embedded option for some approved merchants, and keeps you as the merchant of record.

Two consequences for conversion:

• Your product data becomes the product page. A missing price, a vague title or a wrong stock status costs the sale before anyone sees your site.
• Your own checkout still matters. Most assistants and most shoppers still finish on your site, so a broken cart loses the sales the agent sent you.

1. Make product data complete and consistent

Agents compare offers on facts. Check that every product has:

• A clear title, the right price and currency, and a real availability status.
• Variants (size, colour) exposed as separate, selectable options.
• The same price and stock in your feed, your page text and your Product structured data. Mismatches are a common reason offers are rejected or distrusted.

2. Publish clear shipping and return terms

A shopper buying through an assistant cannot scroll your footer. State delivery costs, delivery times and your return window plainly, on your site and in Merchant Center, and mark up your returns with return policy structured data.

3. Keep your own checkout fast and reachable

Agent traffic and AI referrals both end on your site sooner or later. Make sure every product page has a working add-to-cart control and your cart has a real URL; see add-to-cart button and cart page. Then:

1. Offer guest checkout, so a shopper arriving from an assistant does not hit an account wall.
2. Support the wallets your shoppers already use.
3. Test the full path on a phone, from product page to payment confirmation.

4. Decide whether to join early access

If you sell in an eligible country and already use Merchant Center, read the requirements and join the waitlist. Google's help page notes that checkout currently supports cards stored in Google Wallet and needs a Google Pay & Wallet Console account, usually through your payment provider. If you are not eligible yet, the steps above are still the groundwork.

How Averifly helps

Averifly checks the parts agents and shoppers rely on: the add-to-cart control and cart page (conversion), price and availability on product pages, and Product structured data (catalog). Run a free scan to see what an AI shopping agent would find on your store, or browse all rules.
