🛒 Google keeps moving toward agentic commerce: at Google I/O 2026, they announced Universal Cart, an AI-powered shopping cart designed to work across Google surfaces including Search, Gemini, YouTube and Gmail 👇
Users will be able to add products to a cart while browsing or chatting across these experiences, and the cart will proactively help with things like finding deals and price drops, alerting when products are back in stock, suggesting alternatives, etc.
Google says Universal Cart will start rolling out across Search and the Gemini app in the US this summer, with YouTube and Gmail coming later.
Checkout will be supported through Google Pay for selected brands, or users can transfer items to the merchant site, with the brand remaining the merchant of record.
AI search shopping will be increasingly about whether your product data, availability, prices, attributes, compatibility, offers, reviews and checkout experience are understandable, reliable and actionable enough to be used across AI-assisted shopping journeys.
This also reinforces why ecommerce SEO and AI search optimization can’t be reduced to “content around products”. For ecommerce brands and retailers, this means:
✅ Keep product feeds accurate, complete and fresh
✅ Make product attributes clear and consistent across feeds, pages and structured data
✅ Ensure price, stock, shipping, returns and offers are easy to understand
✅ Strengthen comparison, compatibility and buying-guide content
✅ Avoid relying only on JS-heavy experiences that make key product information harder to extract
✅ Monitor how products and categories are represented across AI shopping surfaces, not only how much AI referral traffic they send
If the shopping journey increasingly happens across Search, Gemini, YouTube, Gmail, carts, agents and checkout flows, ecommerce visibility measurement needs to evolve too: Not just rankings and clicks, but product presence, citation, representation accuracy, recommendation frequency, feed readiness, and assisted demand and conversion signals.
