Google released a major update to the Universal Commerce Protocol (UCP) in early 2026. UCP is an open standard that enables AI agents to communicate with ecommerce platforms and complete purchases on behalf of users. For example, when a user asks Gemini, “Find the best running shoes under $100,” the AI agent can run a search, browse products across retailers, and present relevant options. With user approval, it can then complete the purchase – all enabled by UCP. The update introduces new capabilities, including cart support and access to product catalogs. Google has also simplified onboarding through Merchant Center to attract more retailers. UCP-powered checkout is currently available to eligible U.S.-based merchants, with global expansion planned throughout 2026. Here's how to prepare your business now: social.semrush.com/4xtpRmC.
