Tests of Ads in Google AI Mode – A New Stage in the Evolution of Search

Google is expanding tests of displaying ads inside AI Mode responses, signaling another major step toward deeper integration of sponsored content within generative search. Just a few months ago, ads in AI Mode appeared only sporadically, mostly in experiments limited to select users. Today, the visibility of these formats is clearly increasing, and the experiment is moving into a more intensive and broad phase.

Ads Become a Native Part of AI Responses

The most significant change is that ads are no longer displayed as traditional blocks above or below the results. Instead, they now appear inside the AI-generated answer itself. This means a user may see a product or service suggestion woven directly into the narrative of the AI response - fundamentally changing how they interact with advertising. This format represents an entirely new approach: the goal is no longer to get users to click a separate ad module, but to present a contextual offer that feels like part of the AI’s narrative.

In practice, this looks like the AI presenting recommendations, with an ad immediately below - appearing as an extended sponsored link, a visual card, or an element resembling an organic result. To the user, it appears as part of the answer rather than a standalone advertisement.

Tests and Growing User Reports

Google previously confirmed that it had been testing ads on desktop, but only now are users reporting the appearance of ads in AI Mode at a much larger scale. This suggests the tests have been expanded or rolled out to additional user groups. These are no longer isolated cases - ads are increasingly surfacing in both commercial and service-related queries.

Although Google still labels these actions as “tests,” the pace of rollout suggests the company is laying the foundation for a new monetization model within search.

What Does This Mean for Advertisers?

Introducing ads into generative AI answers means that traditional campaign structures may no longer be sufficient. Contextual relevance - ads that perfectly match user intent - gains importance. In standard search results, keywords played a central role. In AI Mode, what matters more is how well an ad aligns with the narrative generated by the model.

Advertisers should prepare for several important shifts:

New ad formats
Ads within AI Mode do not resemble classic sponsored results. They may appear as product cards, extended text blocks, or modules that look similar to organic snippets.

Greater reliance on automation
The evolving environment suggests that machine-learning-driven strategies—Smart Bidding, broad match, and rich creative assets—will become essential for visibility in generative search.

Contextual relevance over “highest bid”
The algorithm may prioritize ads that best answer the user’s question over those offering the highest CPC. It’s a logical shift: an ad embedded within an AI response must fit seamlessly into its content.

Impact on CTR and SEO
If an ad appears directly inside an AI block, its visibility increases—and the AI response often pushes traditional organic results further down the page. This could reduce the importance of high SEO rankings, especially for product and service queries where AI Mode generates full recommendations.

Generative Search Is Rewriting the Rules

Embedding ads into AI Mode is a natural step in monetizing generative search. Google has been expanding its large-language-model and multimodal capabilities for months, and AI responses occupy increasingly prominent space in the SERP. Ads will likely become a permanent element of this environment.

From a business perspective, this is a major shift. Brands that fail to adapt to the new formats and rules of AI-driven algorithms may lose competitive advantage quickly. Conversely, early adopters stand to benefit from higher CTR, lower costs, and more precise user targeting.
