Mastering the New Merchant Center Attributes

Google has introduced dozens of new data attributes in the Merchant Center specifically for the conversational commerce era. To win the Answer Engine Optimization (AEO) race, your feed must now include:

  • Logic-Based Attributes: Move beyond keywords to include “Compatible Accessories,” “Product Substitutes,” and answers to common FAQs.
  • Real-Time “Ability Profiles”: UCP allows agents to see not just what you sell, but your “capability” to deliver—such as real-time local inventory and 3-hour delivery windows.
  • Direct Offer Integration: A new Google Ads pilot allows you to push exclusive, AI-triggered discounts (e.g., “20% off for first-time agentic buyers”) directly into the AI Mode interface.

The Integration Path: Native vs. Embedded

Google offers two primary ways to implement UCP, depending on the complexity of your business logic:

1. Native Checkout: Best for standard retail. Google handles the UI using payment methods and shipping info stored in Google Wallet. You remain the Merchant of Record and receive the order data via UCP’s REST endpoints.

2. Embedded Checkout: Ideal for luxury or high-consideration brands. This allows you to maintain a custom, branded checkout experience within the AI interface, ensuring you control the aesthetic and loyalty-linking moments.

Preparing for “Business Agent” Deployment

Beyond the protocol, Google is now enabling merchants like Lowe’s and Poshmark to deploy branded Business Agents. These are virtual sales associates that live within Search results. By implementing UCP, you can train these agents on your specific product data, allowing them to provide personalized advice and execute Agentic Handshakes in your brand’s unique voice.

Key Takeaway: UCP is the “on-ramp” to Google’s AI ecosystem. By updating your Merchant Center attributes today, you ensure your products are not just visible, but actionable in the high-intent world of Zero-click commerce.
