What is the Universal Commerce Protocol (UCP)?

UCP is an open standard by Google and Shopify (with 20+ partners including Zalando, Visa and Mastercard) that standardises how AI agents find products, perform checkouts and manage orders.

How can I prepare my store for Agentic Commerce?

Through a product data readiness check, optimisation of structured attributes, a GEO strategy and UCP implementation where applicable. Dr. Roman Zenner consults on all steps.

The next era of e-commerce

Q: What is Agentic Commerce?

Agentic Commerce describes a new era of e-commerce where AI agents autonomously research, compare and buy on behalf of customers. Data quality, machine readability and GEO (Generative Engine Optimization) become decisive.

AI agents that research, compare and buy on behalf of customers — this is fundamentally changing e-commerce. I help you get your store and your data ready.

What is Agentic Commerce?

In traditional e-commerce, customers search, compare and buy on their own. In agentic commerce, AI agents take over these tasks — fully or partially. This changes not only how customers shop, but also what determines whether a store succeeds.

Traditional e-commerce

—The customer searches on Google and in stores
—Shop design and UX build trust
—SEO drives organic traffic
—Product copy is written for humans
—Conversion happens in your own store
