Google introduced the Universal Commerce Protocol, an open standard designed to let AI shopping agents move through product discovery, checkout, and customer service across different retailers. Shopify, Etsy, Wayfair, Target, and Walmart helped develop it. Google plans to use the protocol in Search's AI Mode and Gemini, where eligible shoppers in the United States will be able to buy from retailers without leaving the conversation. Payment and shipping details can pass from a saved wallet into the transaction while brands offer discounts during the recommendation itself.

The protocol gives conversation a cash register. A shopper can describe a room, a budget, and a habit, then receive a product and complete the purchase inside the same answer. Search once exposed a row of links whose differences could be compared. The agent reduces that field to a recommendation shaped by merchant data, advertising offers, wallet access, and rules written into the protocol. Convenience depends on how quietly those interests are combined. Retailers gain a route into the answer, Google retains the interface, and the customer contributes enough personal detail to make the suggestion feel unusually apt. The final click may disappear, but consent still has to occur somewhere. It will be buried in the moment when a helpful sentence becomes an order confirmation.
