Google’s AI Overviews are driving a 10% increase in usage for eligible queries, according to data cited in a DesignRush report sponsored by Intero Digital. This surge coincides with a broader shift where nearly 60% of all Google searches now end without a click, as confirmed by research from SparkToro, Semrush, and the Pew Research Center. In Germany, the impact is more pronounced: since AI Overviews launched in the DACH region in March 2025, the click-through rate for top organic results has dropped from 27% to 11%, according to SISTRIX data cited by ARISE Online Marketing.
The trend reflects a fundamental change in how users interact with search. AI Mode queries are, on average, twice as long as traditional searches, and users are increasingly mixing text, voice, and visuals in single interactions. Brands that rely solely on traditional SEO risk being invisible in AI-generated summaries, even if they rank highly on conventional results pages. Intero Digital reports that clients using Generative Engine Optimization (GEO) saw up to 5,665% more generative search visibility and 189% growth in AI referrals, demonstrating that structured, AI-ready content is now essential for visibility.
Yet appearing in AI Overviews is not enough. A Gartner survey cited in the DesignRush piece found that 53% of consumers still distrust AI-generated results, meaning brands must likewise establish credibility to be effective. Meanwhile, MEXC notes that while overall click volume is declining, the traffic that does come through after an AI Overview tends to be higher in intent — users who click are more engaged and more likely to convert. This shift is forcing a reevaluation of success metrics, moving from raw click volume to quality of engagement and authority within AI-synthesized answers.
The zero-click phenomenon is not limited to consumer searches. B2B sectors are experiencing sharp declines, with Bain & Company reporting up to a 30% drop in click-through rates for B2B software categories. Entail AI observes the steepest declines in B2B SaaS. However, ARISE Online Marketing’s Dimitrios Nikolaidis notes that companies investing in detailed decision-making aids — such as case studies, technical comparisons, and expert knowledge — remain indispensable, with 90% of B2B buyers still clicking through to verify information before purchasing.
Historically, shifts in search behavior have reshaped digital strategy. The current transition mirrors the mobile-first indexing update of 2015, which similarly forced businesses to adapt or lose visibility. But unlike past changes, AI Overviews represent a step-change in sophistication: they synthesize information from multiple sources, construct complete answers, and may cite content without sending any traffic. As MEXC puts it, the fundamental goal of SEO is evolving from winning clicks to becoming a cited authority within AI-generated responses.
What is Generative Engine Optimization (GEO) and how does it differ from traditional SEO?
GEO focuses on structuring content so AI systems can find, understand, and reference it in AI-generated answers across platforms like Google AI Overviews, ChatGPT, and Perplexity. Unlike traditional SEO, which aims to win clicks on search results pages, GEO prioritizes becoming a cited authority within AI-synthesized summaries, even when no direct traffic results.
Why are B2B companies still seeing significant click-through rates despite the rise of zero-click search?
Ninety percent of B2B buyers continue to click through to verify information before making a purchase decision, according to ARISE Online Marketing. Companies that provide in-depth decision-making aids — such as case studies, technical comparisons, and expert knowledge — remain indispensable because AI summaries alone are not sufficient for complex purchasing decisions.
How should website owners measure success in an era of declining click-through rates?
Success metrics should shift from raw click volume to the quality and intent of the traffic that does come through. As MEXC notes, users who click after seeing an AI Overview are more engaged, more curious, and more likely to take action, meaning AI Overviews act as a filter that improves lead quality even as volume decreases.
