Gemini is powering Agentic Commerce: turning curiosity into checkout

The way consumers interact with brands online is undergoing a paradigm shift. We are moving rapidly past traditional keyword searches and entering the era of Agentic Commerce, where AI does not just suggest products but actively guides, reasons and assists shoppers from initial discovery to final checkout.

At csspartner.io our mission is to ensure your business is fully equipped to thrive in this evolving ecosystem. Google has just announced a massive wave of AI-driven commerce updates. Here is a breakdown of what is changing, what it means for your brand and how to optimize your product feed to stay ahead of the competition.

1. The expansion of the Universal Commerce Protocol (UCP)

The Universal Commerce Protocol (UCP) is an open-standard bridge between Google's AI surfaces and your digital storefront — readying your business for the Agentic era. Developed with support from industry leaders and endorsed by 20+ partners, UCP makes your products discoverable across next-generation consumer experiences.

Global expansion of native checkout: the UCP-powered native Checkout experience expands to Canada and Australia in the coming months, followed by the United Kingdom later this year. Consumers can buy directly via AI Mode and Gemini in a fully frictionless purchase flow.

Universal Cart launch: rolling out in the U.S. this summer across Search and Gemini (with YouTube and Gmail to follow), Universal Cart proactively tracks deals, price drops and stock levels — and uses advanced AI reasoning to flag product incompatibilities before the user buys.

2. Going global: 6 new conversational feed attributes

To power conversational commerce on surfaces like AI Mode, Google has globally launched six new data feed attributes in Merchant Center. They complement your existing feed and give the AI the deep context it needs to recommend your products during a natural conversation.

Start updating your feeds with these new attributes today: Popularity Rank, Q&A, Variant Option, Document Link, Related Product and Item Group Title.

3. Meet your new AI co-pilot: Merchant Advisor

Managing complex feed data is about to get much easier. Google is targeting the end of 2026 for the global launch of Merchant Advisor, a conversational chat experience built directly into Merchant Center.

Merchant Advisor lets you "talk back" to your data. You will be able to troubleshoot account health issues, get instant answers to technical feed questions and receive tailored optimization advice to boost your performance.

Future-proofing your business: the 4 pillars of feed health

In the era of Agentic Commerce your product feed is your ultimate leverage. High-quality data is the foundational enabler for your products to be discovered across Google's AI ecosystem — maximizing both organic reach and the power of your performance campaigns. Focus on these four pillars:

Inform with rich titles and descriptions

Help the AI precisely match your products to how users naturally search and converse: write descriptive titles with 30+ characters, provide detailed descriptions with 500+ characters and ensure all relevant products include unique identifiers like GTINs.

Engage with multiple image creatives

Consumers are shopping more visually than ever. Include 3+ additional images per product, add lifestyle shots that show your product in use and keep image quality high-resolution — ideally 1500×1500 px.

Highlight shopping convenience

Provide transparency upfront so shoppers can make confident decisions: explicitly indicate free shipping, share clear shipping speeds and display your return policy.

Show the differentiators shoppers care about

Set your brand apart at the exact moment a consumer is choosing between you and a competitor: submit accurate sale prices and product ratings, categorize your inventory granularly by product type and share compelling product highlights.
