Google Search Gets Information Agents and Universal Cart

At Google I/O 2026, Google announced two significant agentic features coming to Search: information agents that continuously scan the web on a user's behalf and Universal Cart that aggregates products from multiple retailers into a single basket. These developments have the potential to fundamentally reshape search behaviour and digital marketing dynamics.

Bit DedeKey takeaways

• Information agents continuously scan the web after a user's initial query and send back intelligent, synthesised updates with the ability to take action; they will roll out to Google AI Pro and Ultra subscribers first, with a broader timeline not yet announced.
• Universal Cart aggregates products from multiple retailers inside Google Search and Gemini, with checkout completing on the merchant's site; only stores integrated with the Universal Commerce Protocol (UCP) are eligible to appear in the cart.
• Information agents are likely to reduce direct organic traffic volumes because they synthesise answers before users visit sites; the compensating factor is that visitors who do arrive carry significantly higher purchase intent.
• Agentic search optimisation favours entity clarity (structured data, unambiguous brand and product definitions), topical authority through in-depth content clusters, and clear H2/H3 structure with summary paragraphs that agents can parse quickly.
• For e-commerce, UCP integration is the most urgent infrastructure step: as Universal Cart expands globally, stores without UCP support will be invisible to users shopping through Google.

What Are Information Agents?

Information agents are AI units that continue scanning the web after a user's initial query and send back periodic updates. According to Elizabeth Reid, Google's VP of Search, the agents deliver "an intelligent, synthesized update, with the ability to take action."

Information agents will roll out to Google AI Pro and Ultra subscribers this summer. Example use cases include monitoring a product for a price drop, receiving an alert when a new flight route opens, or tracking a regulatory change. Rather than searching repeatedly, the user delegates the task to an agent, which reports back when it finds a result.

Universal Cart

Universal Cart will function as a central shopping hub within Google Search and Gemini. Users can gather products from different retailers into a single cart; payments are completed on the merchant's own site. Google handles price comparison and deal-finding in between.

The service launches in the US this summer and will later expand with YouTube and Gmail integration. Brands including Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair and Shopify are among those joining at launch.

Other Agentic Updates

Google I/O announcements went further than these two headline features:

• Agent Payments Protocol (AP2): Lets users set guardrails (such as budget limits and brand preferences) for agentic transactions.
• Agentic Booking: Expanding to cover local experiences and services.
• Universal Commerce Protocol (UCP) Checkout: Expanding to Canada and Australia, with the UK to follow.

What This Means for Marketers: Less Traffic, Higher Intent

Because information agents research and synthesise results on a user's behalf, direct website traffic may fall. However, visitors who do arrive are likely to be much closer to a purchase decision: the agent has already done the filtering, and the user lands on the page with clear intent.

This makes conversion readiness as important as visibility. Maintaining or growing revenue despite lower traffic volumes depends on having the right pages optimised with the right signals. Bottom-of-funnel pages need a clear CTA, strong social proof and fast load times.

For e-commerce brands, the immediate priority is UCP readiness. As Universal Cart expands, only UCP-enabled stores will be eligible to appear in users' carts. That elevates infrastructure preparation well beyond a routine feature update.

How to Prepare for Agentic Search

The foundations of agentic search optimisation are not far removed from solid technical SEO principles, but a few areas deserve specific focus:

• Entity clarity: Your brand, products and services need to be clearly defined through structured data. Agents skip ambiguous content.
• Topical authority: In-depth content clusters on a single subject earn more citations than broad, shallow content.
• Clear structure: H2/H3 hierarchy, summary paragraphs and Q&A format make it easier for agents to interpret your content.
• High-intent page optimisation: Visitors arriving via agent filter are ready to act. Clear CTA, fast load speed and strong social proof are non-negotiable.
• UCP integration (e-commerce): The first infrastructure step to appear in Universal Cart.

In this environment, it is worth revisiting your SEO strategy not just through the lens of rankings, but through AI visibility and conversion optimisation as well.
