In the zero-click era, the central question is no longer whether Google can generate traffic, but whether it can monopolize attention. SparkToro’s 2024 clickstream study found that 58.5% of U.S. Google searches ended without a click to the open web, while Ahrefs estimated that the presence of an AI Overview cuts the click-through rate of the top organic result by roughly 34.5%. Meanwhile, Google says AI Mode has already surpassed one billion monthly active users globally, with query volume more than doubling every quarter since launch. (sparktoro.com)
Yet this does not mean search advertising is collapsing. On the contrary, Alphabet reported that Google Search & other revenue rose 17% year over year to $63.1 billion in Q4 2025, and Google is actively inserting new ad inventory into AI-driven search. According to Google Ads Help, ads are now eligible to appear above, below, or within AI Overviews, and in-overview ads are available in English across countries including the U.S., Canada, India, and Australia. At Google Marketing Live on May 20, 2026, Google also introduced new AI-era formats such as Conversational Discovery ads, Highlighted Answers, AI-powered Shopping ads, Business Agent for Leads, and expanded Direct Offers within AI Mode.

The deeper change, then, is strategic rather than merely financial. Google states that ads in AI Overviews are matched not only to the user’s query but also to the content of the AI-generated response, and it recommends AI-powered targeting such as broad match, Performance Max, and AI Max. Google has gone further still: beginning in September 2026, legacy Dynamic Search Ads and related settings will be automatically upgraded to AI Max. The implication is hard to miss: defending a brand with a narrow exact-match playbook is becoming less adequate than building a machine-readable brand presence across site content, product feeds, pricing, imagery, and offers.

So Google’s AI Mode may not slash brand budgets so much as reallocate them. Less spending will be justified by simple branded-click protection alone; more will flow toward creative assets, structured commerce data, AI-compatible landing pages, and measurement systems that can value influence before the click. In a conversational SERP, the brand that is easiest for Google’s models to understand may gain the decisive advantage before the user ever reaches the website. (support.google.com)
