TLDR: Google’s Head of Search, Liz Reid, asserts that AI Overviews are leading to “higher quality clicks” and an overall increase in search queries, despite third-party studies indicating significant declines in organic and paid click-through rates for websites. The debate centers on whether AI-generated summaries are enhancing user experience and driving more valuable interactions, or if they are cannibalizing traditional web traffic and ad revenue for publishers.
The introduction of AI Overviews (AIOs) by Google has ignited a significant debate within the digital marketing and publishing industries. Liz Reid, Google’s VP and Head of Search, has publicly defended AIOs, stating that they are driving “more queries and higher quality clicks.” According to Reid, when users click through from AI Overviews, they “bounce less and engage longer,” which she describes as “higher quality” visits. She also points to “deeper scroll behavior and a broader diversity of cited sources.” Google maintains that it continues to see “overall query growth in Search,” including from Apple devices, despite Apple’s claims of declining Google search volume from Safari. John Mueller, Google’s Search Advocate, further reinforced this, stating that “when people click to a website from search results pages with AI Overviews, these clicks are of higher quality, where users are more likely to spend more time on the site.” Google’s internal data suggests that “total organic click volume from Google Search to websites has been relatively stable year-over-year,” and they are “sending slightly more quality clicks to websites than a year ago.”
However, this narrative is sharply contradicted by numerous third-party analytics firms and SEO experts. Studies from various sources paint a picture of significant traffic declines:
Organic Traffic: MOZ’s 2025 research indicated that organic traffic could fall by 18% to 64%, particularly for informational sites. Ahrefs reported in April 2025 that the presence of an AIO cut position-one click-through rate (CTR) by 34.5%. Earlier in February 2025, Ahrefs found that organic CTR on AIO queries slid from 1.41% to 0.64% year-over-year, marking a 54.6% decrease across approximately 10,000 informational keywords. Authoritas, in a legal complaint to the UK’s Competition and Markets Authority, found that publishers experienced a 47.5% drop in per-query CTR on desktop and 37.7% on mobile when an AI Overview was present.
Paid Traffic: Early tests suggest that paid CTR almost halves in AIO-heavy Search Engine Results Pages (SERPs), with paid CTR falling across the board.
Zero-Click Searches: Data from Similarweb showed that zero-click news searches increased from 56% in May 2024 (when AIOs first launched in the US) to almost 69% in May 2025. A Bain survey from December 2024 indicated that 80% of consumers now rely on zero-click search results for at least 40% of their queries.
AIO Trigger Rate: Semrush’s 2025 data revealed that 13.14% of all queries triggered AI Overviews in March 2025, a notable increase from 6.49% in January 2025.
The impact on publishers has been severe, with many reporting significant revenue consequences. Some independent website owners have seen visits plummet by 70-90%. Travel bloggers Dave Bouskill and Debra Corbeil, for instance, experienced a 90% traffic drop after AI Overviews began reproducing their content. The education platform Chegg has attributed a 49% traffic plunge and revenue hits to AIOs, leading to an antitrust lawsuit against Google. Brazilian publishers have also demanded action, reporting a 34% traffic cut across their content sites due to AIOs.
SEO experts have voiced strong criticism regarding Google’s “quality clicks” metric. Laurence O’Toole, CEO of Authoritas, argued that this “new” metric serves to “divert attention away from the fact that a much lower percentage of users are clicking through to websites than before.” David Buttle of DJB Strategies called Google’s blog post “desperate conjecture and spin,” noting its lack of concrete data and an undefined “quality click” metric. Barry Adams, an SEO consultant, likened Google’s stance to George Orwell’s “1984,” stating that “Every single study… shows the exact same thing: A significant drop in clicks.” Lily Ray, VP of SEO strategy at Amsive, questioned whether Google Search Console screenshots showing flat or increasing impressions with dramatically declining clicks count as “flawed methodologies.” Aleyda Solis, also from Amsive, contended that any overall stability in search traffic primarily benefits large platforms like Reddit (with whom Google has a content licensing partnership) and Google’s own YouTube, rather than the broader ecosystem of smaller, independent sites.
Monetization and advertising are also undergoing changes. Google asserts that AIOs create “a lot of opportunities for ads—above, below and within the overview—but only when commercial intent is clear.” However, ad inventory is expected to shift towards more integrated formats like shopping carousels and shoppable images embedded within AIOs. Early tests indicate that the cost of gaining attention may rise, as paid CTR almost halves in AIO-heavy SERPs. Marketers also face performance reporting gaps, as Search Console currently does not differentiate between AIO clicks and classic web listings.
Search behavior is evolving, with users increasingly asking “longer, multi-part questions” and utilizing “multimodal inputs” such as image-plus-text queries. There is a growing “expectation of immediate answers,” which AIOs aim to satisfy for quick facts and comparisons. Users are also seeking “authentic voices and first-hand perspectives” from forums, videos, podcasts, and posts, a trend that Google’s early 2024 partnership with Reddit to license content for AI training has likely influenced, boosting Reddit’s prominence in search results.

In conclusion, while Google, through Liz Reid, champions AI Overviews as a driver of increased search volume and higher-quality, more engaged clicks, the industry remains divided. Independent data consistently highlights a reduction in overall click-through rates for websites, posing significant challenges for publishers and marketers. The ongoing debate underscores a fundamental shift in how users interact with search, compelling content creators to adapt to an AI-first environment where visibility is fragmenting and the traditional value exchange with Google is being redefined.
