New research from Ahrefs suggests that Google’s AI Overviews are accelerating the shift toward zero-click search, significantly reducing traffic flowing to external websites. According to the study, top-ranking organic pages now receive 58% fewer clicks when AI Overviews appear in search results, raising new concerns for publishers, SaaS companies, marketers, and digital businesses increasingly dependent on organic visibility.

Google’s AI-driven transformation of search is beginning to produce measurable consequences for the broader web economy.

A new study released by Ahrefs found that Google’s AI Overviews are now reducing clickthrough rates for top-ranking organic search results by an average of 58%, up sharply from the 34.5% decline observed less than a year earlier.

The findings suggest that AI-generated summaries are increasingly absorbing user attention directly inside search results pages, reducing the need for users to visit external websites altogether.

The study analyzed 300,000 keywords using aggregated Google Search Console data, comparing performance between December 2023 — before the rollout of AI Overviews — and December 2025.

According to Ahrefs, the impact extends well beyond the top organic listing.

Pages ranking in position two reportedly lost roughly half of their clicks, while even pages positioned near the bottom of the first search page experienced measurable declines approaching 20%.

The research reinforces growing concerns across the publishing, SaaS, e-commerce, and digital marketing industries that generative AI may fundamentally alter the economics of search-driven traffic acquisition.

“Search is becoming zero-click,” said Ryan Law. He noted that users increasingly receive answers directly within Google’s interface rather than navigating to publishers, brands, or informational websites.

The concept of zero-click search is not entirely new.

Featured snippets, knowledge panels, People Also Ask modules, and map packs have already reduced outbound traffic for many query types over the past decade. But AI Overviews appear to represent a more aggressive evolution because they synthesize information directly into conversational summaries capable of answering complex informational queries without requiring additional exploration.

That shift is particularly significant because informational search has historically served as one of the largest traffic drivers for publishers and content-heavy businesses.

The implications could reshape how marketers measure search visibility itself.

Historically, SEO strategies focused heavily on ranking position, organic traffic, and clickthrough rates. But as AI-generated search interfaces become more dominant, visibility inside AI-generated summaries, brand recognition, and citation presence may become equally important performance metrics.

This transition is already forcing marketers to adapt toward Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) strategies designed to improve visibility inside AI-generated search responses.

The findings also highlight Google’s increasingly complex position within the digital publishing ecosystem.

For years, Google’s search engine operated as the primary traffic distributor across the web, sending billions of visits to publishers, businesses, and creators. AI Overviews potentially shift more value capture directly onto Google’s own interface by keeping users inside search results longer.

That dynamic is creating growing tension between platform optimization and publisher sustainability.

Google has previously argued that AI-generated search experiences can drive higher-quality traffic and improve user engagement. But studies like Ahrefs’ suggest the net volume of outbound clicks may continue declining as AI summaries become more comprehensive.

The broader competitive landscape is also evolving quickly.

AI-native search platforms such as Perplexity AI and conversational systems from OpenAI are training users to expect direct answers rather than lists of links.

At the same time, Google is under pressure to defend its search dominance as generative AI changes how users interact with information online.

Research from Gartner has projected that traditional search engine volume could decline significantly over the next several years as users increasingly shift toward AI-driven conversational interfaces.

Meanwhile, Forrester has warned that brands dependent on organic discovery may face mounting acquisition challenges as AI systems intermediate more of the customer journey.

The impact is likely to vary across industries.

Publishers, affiliate websites, informational SaaS blogs, and comparison platforms appear especially vulnerable because their business models depend heavily on high-volume informational search traffic.

Brands with strong direct relationships, subscription ecosystems, or recognizable authority may prove more resilient.

The rise of AI Overviews is also accelerating a broader strategic shift in SEO itself.

Modern search optimization increasingly involves building entity authority, strengthening brand recognition, improving multi-platform discoverability, and creating content structured for AI citation rather than simply targeting keyword rankings.

Ahrefs says it is continuing to track the performance impact of various search engine results page features, including discussions, videos, forums, and AI-generated experiences.

The larger challenge for marketers is that search visibility no longer guarantees traffic.

In the AI era, ranking first may no longer mean owning the click.

Market Landscape

The search industry is undergoing one of its most significant structural changes since the rise of mobile search and social media platforms.

Generative AI is rapidly transforming search engines from link-based discovery systems into answer-generation interfaces that increasingly satisfy user intent directly within platform environments.

This shift is accelerating the rise of zero-click search behavior, where users consume information without visiting external websites.

AI-generated search summaries, conversational interfaces, and answer engines are fundamentally changing how publishers, SaaS companies, e-commerce brands, and marketers approach content visibility and customer acquisition.

As a result, SEO strategies are evolving toward Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), entity authority building, and multi-platform discoverability.

At the same time, publishers and content-driven businesses face growing uncertainty around traffic sustainability as search platforms capture a larger share of user engagement directly within AI-enhanced search experiences.
