What UCP Means for Ecommerce SEO: Preparing for Agentic Marketing – International SEO Consultant, Author & Speaker

A few days ago, Google announced the Universal Commerce Protocol (UCP)“a new open standard for agent commerce that applies to the entire shopping journey”, enabling interactive, end-to-end agent commerce across all platforms by integrating discovery, talent negotiation, and commerce functions (eg checkout, orders, post-purchase).

What are the results in Ecommerce SEO?

UCP is changing ecommerce SEO by expanding its scope. Below is a first impression of what UCP means for ecommerce SEO, based on what was revealed in the announcement and official documents of implementationconsidering when to join the waiting list.

1. Merchant Center remains basic, now with expanded features

Google’s UCP implementation built upon Google Merchant Center presencetherefore it is necessary to have a properly configured profile, as well as a valid product feed and certain configurations required by Google:

• Return policy: You should explain your return policies to the Merchant Center.
• Customer support information: You must set up your customer support information in the Merchant Center.
• Product data: You must review your product feed to demonstrate eligibility and provide compliance data, such as: agent release eligibility, product warnings, product identifier.

What’s really new are the commercial chat attributes.

Google announced that it is introducing new data attributes in the Merchant Center designed specifically for AI-driven discovery, to answer common product questions, compatible devices, product replacements, and detailed use cases.

Definition of SEO: Feed quality, policy accuracy, and data freshness are still the gateway to inclusion, now with even higher numbers. In addition, preparing chat attributes is important for visibility in AI mode, Gemini, and business agent interactions.

2. Dealer trust becomes a hard requirement, not a soft signal

UCP formalizes an SEO concept that has historically had an indirect impact: merchant trust.

Agent trading depends on:

• Stable merchant identity
• Consistent data across systems
• Predictable fulfillment, returns, and payment behavior

SEO offers to ensure:

• Clear business representation
• Transparent policies
• Strong reputation indicators (reviews, authoritative mentions)

This goes beyond traditional EEAT considerations. Trust is direct agent’s willingness to actnot just appearances.

3. The planned data of the product becomes the basis

AI agents rely on structured data, feeds, and APIs.

For ecommerce SEO, this increases the importance of:

• Organized product data, offers, and AggregateRating
• Accurate pricing, availability, shipping, and markup policy
• Alignment between on-site structured data and Merchant Center feeds
  

Google has historically proven product delivery against site data, and under the UCP, inconsistency carries great risk because it can block the agent’s sales entirely.

Definition of SEO: Your website is now a data source that powers commerce across multiple systems. Organized, accessible and accurate data ensures that your products are always available and affordable, whether people are browsing or trading agents.

4. Ecommerce SEO is changing from “ranking pages” to “enabling transactions”

Traditional SEO for ecommerce focuses on ranking category, product, guides and product pages to drive traffic. With UCP, optimization extends what an AI agent can:

1. Discover the skills of a salesperson
2. Trust the seller’s data
3. Complete checkout and post-purchase transactions reliably
   

If any of these fails, the seller can be kicked out, regardless of the page type.

Definition of SEO: Validity and reliability of performance are as important as visibility.

5. Discovery is “power-based”

• Classic ecommerce SEO asks: “Can Google find and rank this product page?”
• UCP ecommerce SEO should also ask: “Can an AI agent confidently call this seller to complete a purchase?”

With UCP, vendors will need to publish a JSON manifest to /.well-known/ucp that lists their available services and capabilities. AI agents download this manifest to find features, endpoints, and payment settings without hard-coded integration.

That depends published capabilities (via a manifest), accurate declarations (what the vendor can and cannot do), and reliable execution.

Definition of SEO: Imperfect or abstract power means invisible, even solid products. Vendors must disclose and explain what capabilities they support, including intended functionality.

6. Traffic is no longer a reliable success metric

UCP-enabled commerce can transform transactions into AI-driven traffic that doesn’t generate traditional page views or sessions. As a result:

• Google Analytics may not capture these changes through standard client-side tracking.
• Google has not yet published detailed statistics or attribution guidelines for UCP.

It is likely that the server-side attribute and back-end order data will be important, as merchants are always the Merchant of Record and receive order data through their trading platforms.

Definition of SEO: SEO teams must communicate new measurement frameworks and success metrics. Whether high conversion and margin control will offset the loss of direct site traffic is still an open question, the industry should develop new attribution models for agent-directed activities.

7. SEO becomes cross-functional

SEO professionals will need to work closely with Engineering, Product & Operations, and Legal & Compliance:

• Return policies should be explained in the Merchant Center.
• Customer support information must be set.
• Product IDs in the feed must match those expected by the Checkout APIs.
• Policy accuracy and data freshness directly at the eligibility gate.

SEO becomes a role that identifies acquisition risks, ensures that sellers’ presentations are consistent across systems, and prevents silent exclusion from AI’s commercial flow.

Effective Action Items for Ecommerce SEO Teams

1. Check the completeness and accuracy of the merchant facility following UCP specifications.
2. Ensure structured product data and feed alignment
3. Improve product data clarity for AI definition (features, use cases, alternatives)
4. Check out how AI platforms present products in your category
5. Prepare the analytics infrastructure for AI operations

The TL;DR

The transition to agent marketing represents an expansion of the scope of ecommerce SEO, not its replacement. Traditional values, such as quality content, accurate product data, strong brand authority, remain important. But now they serve a dual purpose: guiding human users and enabling AI agents to act on behalf of those users.

Brands that understand this change -and prepare for it now- will appear where the decisions are made, not just where the clicks were.
