Google launches Universal Cart in Search and Gemini

Google has launched Universal Cart in the United States through Google Search and the Gemini app, according to Search Engine Journal. The feature lets shoppers save items from multiple retailers in one cart, receive price drop and back-in-stock alerts, and complete purchases either through Google Pay or by going to a participating retailer’s website.

The report says Google first announced Universal Cart in May. The new launch also clarifies how cart transfers work for participating merchants and what store reporting may be available in Merchant Center.

What changed

Universal Cart is now live in U.S. Search, including AI Mode, and in the Gemini app. Shoppers can keep items from several stores in a single cart across both places. Google says the cart is built on Google Wallet, can show promo codes, and may suggest which card to use based on card perks.

Search Engine Journal notes that some details mentioned in May are not included in the launch post. The new post does not mention timing for YouTube or Gmail support. It also does not describe historical pricing, product compatibility warnings, or loyalty program information that appeared in the earlier announcement.

What it means for your website

If your store participates, Google may become a stronger starting point for shopping visits, not just a place where people discover products. A shopper can save products in Google’s cart and later either finish checkout within Google or transfer those items into a cart on your website. In the transfer setup described by Google’s developer documentation, the merchant remains the seller of record.

For business owners, this means some shopping activity may begin and stay inside Google’s interfaces longer before the customer reaches your site. Search Engine Journal also reports that Google tracks cart transfers and purchases separately in its Universal Commerce Protocol reporting. At the same time, the article says no metric is listed for products merely saved to a cart.

What to do now

• Check whether your store has access to the UCP integration hub in Merchant Center, since the rollout is gradual in the U.S.
• Review whether your setup supports cart transfer, native checkout, or both, and confirm which option is selected in the integration hub.
• Monitor Merchant Center analytics for buy clicks, purchases, cancellations, and cart transfer activity if your store is participating.
• If you run Shopify, verify whether Direct Checkout is enabled for your eligible U.S. store and note that Shopify says Google Analytics and Custom Pixels will not fire for purchases completed through Direct Checkout.
• Keep an eye on future Google updates for any timeline on YouTube and Gmail support, since the launch post did not include that information.
