Google has rolled out a suite of new commerce tools that promise to make online shopping more seamless than ever. The company announced the Universal Cart, an expansion of its Universal Commerce Protocol (UCP) and the Agent Payments Protocol (AP2), and revealed that its Shopping Graph now contains 60 billion product listings. These updates aim to give shoppers a single, unified shopping experience while giving retailers a broader, more efficient way to reach customers.
Universal Cart: A Unified Shopping Experience
At the heart of Google’s new features is the Universal Cart. This tool lets users add products from multiple retailers into one cart directly from Google Search, Gemini, YouTube, or Gmail. Once items are in the cart, shoppers can review the best prices, check inventory status, and complete the checkout using Google Wallet—all with a single click.
Unlike traditional shopping carts that are tied to a single merchant’s website, the Universal Cart is built on Google’s payment infrastructure. This means it can automatically apply any loyalty rewards, coupon codes, or payment method perks that the user has set up in Google Wallet. The result is a frictionless checkout process that saves time and reduces the number of steps required to complete a purchase.
Expanding the Universal Commerce Protocol and Agent Payments Protocol
Google’s Universal Commerce Protocol (UCP) is the backbone that allows product data from different retailers to be harmonized and displayed across Google’s services. By expanding UCP, Google is making it easier for merchants to list their products in a standardized format that can be understood by the Universal Cart and other Google commerce tools.
The Agent Payments Protocol (AP2) takes this a step further by enabling third‑party agents—such as shopping assistants or AI chatbots—to process payments on behalf of users. With AP2, a virtual assistant could add an item to a user’s cart, negotiate a price, and complete the transaction without the user having to leave the conversation.
The Growing Shopping Graph
Google’s Shopping Graph is the database that powers product discovery across the company’s ecosystem. Vidhya Srinivasan, VP/GM Ads & Commerce, announced that the graph now contains 60 billion product listings, up from 50 billion earlier in the year. This massive growth reflects the increasing number of merchants and product categories that Google is indexing.
With more listings, the Shopping Graph can deliver richer search results, better recommendations, and more accurate price comparisons. It also means that merchants who list their products in the graph can reach a wider audience across Google Search, YouTube, and other platforms.
How the Universal Cart Works Across Google Services
Users can add items to the Universal Cart from any Google interface:
- Google Search: Click the “Add to cart” button that appears next to product listings.
- Gemini: When a user asks about a product, Gemini can suggest adding it to the cart.
- YouTube: Product links in video descriptions or comments can be added with a single tap.
- Gmail: Shopping emails or product recommendations can be added directly from the inbox.
Once items are in the cart, Google automatically checks inventory across all participating retailers. If a product is out of stock, the cart will suggest alternatives or notify the user when it becomes available. The cart also flags potential compatibility issues—such as incompatible PC parts—so shoppers can avoid costly mistakes.

- One‑stop shopping across multiple brands.
