Google has officially outlined the direction for digital advertising and e-commerce in 2026 – and this is no longer just about automation. We are entering an era where artificial intelligence becomes the environment for interaction between a brand and a customer.

If previously advertising led users to a website, it is now embedded directly into the process of thinking, choosing and buying. The biggest changes are observed in two areas: AI ads in search and the so-called agentic commerce – purchases without leaving the AI interface.

AI Search: Advertising Becomes Part of the Conversation

Google is actively developing the AI Mode format – a conversational search experience in which users don’t just type keywords but formulate their requests as a dialogue: they specify budget, compare options and ask for recommendations.

This is where the logic of advertising changes.

Ads are no longer a separate block above search results. They are integrated into the context of the AI’s response. When a user asks, for example, “which running shoes are suitable for a marathon under 5,000 UAH,” the system not only provides recommendations but can also show relevant brand offers marked as Sponsored – at the very moment when purchase intent has already been formed.

This is a fundamentally different level of interaction:

  • AI analyzes the context of the conversation, not just the keyword
  • ads appear during the decision-making phase
  • the user sees not just a product, but the reasoning and comparison

In essence, Google is trying to shorten the path from query to action. In the new logic, an ad is part of the recommendation rather than a distracting element.

For businesses, this means one thing: it will no longer be enough to work only with keywords – you’ll need to work with full intent scenarios. The winners will be the brands that can provide AI with structured, complete and competitive data: feeds, prices, availability, USPs and promotions.

Direct Offers: The Right Proposal at the Moment of Purchase Readiness

Google is also testing the so-called Direct Offers format – where an advertiser can submit a special deal that AI displays at the moment of high commercial intent.

This is not just a “-10%” banner. It is an integrated part of the response: AI sees that the user has already chosen a category, specified the characteristics, compared options – and only then shows a special offer.

The focus shifts from reach to timing precision.

Agentic Commerce: When AI Buys Instead of the User

The most radical change is the development of agentic commerce.

The idea is that an AI assistant not only recommends a product but can also perform actions on behalf of the user: find the best price, check delivery, apply a coupon and even complete the purchase.

Google is promoting the concept of the Universal Commerce Protocol (UCP) – a standardized system that allows AI to interact directly with stores and payment services.

What does this mean in practice?

  • The user communicates with AI
  • AI suggests a specific product
  • The purchase can happen прямо inside the interface – without going to a website

In fact, the classic chain “search → website → cart → checkout” can be reduced to a single dialogue.

Here, businesses face a new reality: not only the website matters, but also whether your infrastructure is ready to work within the AI environment.

What This Means for Advertisers

  • Data becomes critically important. Structured feeds, accurate pricing, and real-time availability are essential – without them AI simply won’t be able to recommend your product.
  • Performance strategy will become increasingly automated. Campaign types like Performance Max, Shopping and AI-optimized video are no longer a trend – they are the baseline.
  • Creative is transforming. In the AI world, advertising must match the context, not just be visually striking.

Will Websites Disappear?

No. But their role will change.

A website will become:

  • a trust signal
  • a source of structured data
  • a platform for complex decisions

Simple purchases will increasingly happen within AI environments.

The Key Takeaway

2026 is the moment when AI stops being just an optimization tool and becomes a commerce environment.

Advertising no longer competes for attention – it integrates into decision-making. Purchases no longer require multiple transitions – they become part of the dialogue.

For businesses, this means one thing: adapting to the AI ecosystem is no longer a matter of innovation – it is a matter of competitiveness.
