Google’s universal commerce protocol is a win for everyone

Until recently, I viewed Google as the dominant ’dinosaur’ that OpenAI’s ChatGPT would quickly erode.

 

However, after watching the TV documentary about Demis Hassabis, the CEO of DeepMind, the acquisition that formed the foundation of Gemini, I was highly impressed by his vision and drive.

 

I was therefore less surprised by Gemini’s massive leap in functionality, which prompted a recent ’code red’ message from Sam Altman, the CEO of OpenAI, to his programming team, warning of the need to rapidly catch up.

 

For the past few years, we have all wondered how large language models (LLMs) would develop a commercially viable product that enables them to generate revenue while still providing the correct answer to the customer with the fewest clicks.

 

To be honest, I expected Google to be the last to dismantle its decade-old directory of blue links that maximise revenue by forcing travel customers to visit 76 sites on average to research holidays before making a booking.

 

However, Google’s announcement of the Universal Commerce Protocol (UCP) marks a pivotal moment in the evolution of digital commerce. For years, online shopping has been optimised around websites, apps, and funnels.

 

Now, Google is signalling a future where the interface itself is intelligent, capable of researching, conversing, and completing purchases on a consumer’s behalf. Far from being a threat to retailers, this shift has the potential to make commerce more open, more human, and significantly more efficient.

 

At the core of this announcement is a straightforward and powerful idea, but not a new one: if AI agents are to assist people with shopping, the underlying commerce infrastructure must have a shared language. Without common standards, every retailer, payment provider and AI system would be caught in an endless cycle of one-off API integrations.

 

Yup, a carbon copy of the Anthropic MCP concept, but under a new Google UCP banner! However, let’s face it, Google has far more leverage to force this through than its new AI search competitors.

 

From search results to shopping outcomes

 

For consumers, the promise of agentic commerce is obvious. Shopping online today often feels like work: multiple tabs, repetitive forms, forgotten passwords, and abandoned carts. AI agents change that dynamic. Instead of simply pointing users to products, agents can answer nuanced questions, compare alternatives, apply discounts, and complete checkout in a single conversational flow.

 

Google’s plans to integrate agentic checkout directly within search and the Gemini app are particularly significant simply because Google is the world’s largest search engine. This isn’t merely about convenience; it’s about purpose. When someone is actively researching a product, that moment of decision becomes extremely valuable.

 

Enabling checkout at that exact point, without redirecting to another site, minimises friction when users are most ready to make a purchase and, logically, boosts conversion. Just think how much more stuff you buy from Amazon because it’s there when you think of it, and it can be delivered the next day with just a few clicks.

 

Crucially, Google has been clear that retailers remain the seller of record. This isn’t Google becoming an Amazon marketplace in disguise. Instead, it’s positioning itself as infrastructure: a connective layer that helps transactions flow more smoothly while leaving fulfilment, branding, and customer relationships firmly in the retailer’s hands.

 

Why open standards matter

 

One of the most encouraging aspects of UCP is its emphasis on openness. Google is framing the protocol as an industry standard rather than a proprietary system. It’s designed to work alongside existing protocols and across retail categories, payment networks, and AI platforms.

 

This matters because trust in agentic systems will depend on interoperability. Consumers won’t want one AI agent for groceries, another for travel and a third for household goods, each locked into its own ecosystem. Likewise, retailers don’t want to rebuild their commerce stack every time a new AI surface emerges. By lowering technical barriers, UCP creates the conditions for healthy competition and faster innovation.

 

Business agent and the return of the sales assistant

 

Another standout element of Google’s announcement is the creation of Business Agents.

 

This is the first implementation of Voice AI into the search process, allowing customers to have AI-powered conversations with the business about its products, just as they do with shop assistants in stores.

 

For retailers, this introduces a new form of high-intent engagement. Imagine being able to chat with the customer, deliver content quickly and simply, answer those last few questions, and close the sale. AI Voice may never match a human salesperson, but it is a fraction of the cost and can be delivered promptly exactly when the customer needs it, 24/7, in 42 different languages.

 

Importantly, Business Agent is built on retailer-controlled data via the ’Merchant Centre’. Brands decide how the agent behaves, what information it uses, and how it represents them. In an AI-driven world, that level of control is essential, and the next AI Race will be to develop the best sales agents through “test and learn” evolutions led by experts like my own Travel Voice Team.

 

AI-native commerce, not just AI on top

 

What ties all of Google’s announcements together is a clear shift toward delivering AI-native commerce. This isn’t about bolting AI onto existing systems. It’s about redesigning commerce for a world where AI mediates discovery, decision-making, and acts, in one seamless flow.

 

Google, as the leading search engine, is much more likely to drive the retailer’s required action, and it has already provided much more transparency about exactly what is required than the alternative MCP protocol.

 

With most Travel companies seeing a disastrous decline in the effectiveness of traditional PPC traffic generation, UCP is a lifeline that they need to reach out and grab with both hands.

 

What assistance could Travel Voice provide?

 

Travel Voice is laser-focused on this opportunity and has expertise not only in UCP but in implementing AI Voice agent systems across all customer touchpoints, not just Google Brand Search. 

 

This ranges from 24/7 AI ’Brand Ambassadors’ on your website to answer FAQ’s and set up sales appointments with Human colleagues, to AI Voice Reps that guide customers through their holiday using AI Voice as a connector to the entire knowledge of the internet about the resort.

 

This in turn leads to an AI review gathering where the customer has a contextual chat about their holiday to build a UGC database that can power your own reviews database, searchable by voice, for staff, travel agents or customers alike.

 

These reviews can also generate digital “word of mouth” by automatically inserting your brand and sales staff details into hotel reviews that are auto-generated for customers to post on Tripadvisor, Google Reviews, or other trusted sites that LLMs are likely to use for AI Search Responses.

 

AI Voice will rapidly become part of everyday life, so it’s time to prepare for the future.
