AI Overviews Are Reshaping Search Traffic
New research is putting hard numbers behind a trend publishers and marketers have suspected for months: Google's AI Overviews are significantly eroding click-through rates on traditional organic search results. Two separate analyses, released in overlapping windows of 2024 and 2025, converge on the same conclusion even as they diverge on the scale of the damage.
What the Data Shows
The more rigorous of the two studies comes from Seer Interactive, which tracked 3,119 informational search queries across 42 organizations between June 2024 and September 2025. The firm analyzed a substantial dataset — 25.1 million organic impressions and 1.1 million paid impressions — to measure how the presence of AI Overviews changes user behavior on the search results page 1. That study reportedly found click-through rates falling by as much as 61% on queries where Google's AI-generated summary appears above traditional blue links 1.
A separate report frames the impact as even steeper, claiming publisher CTRs have dropped by more than 70% in the wake of AI Overviews' rollout in 2024 2. While the two figures don't match precisely, both point in the same direction: when Google answers a query directly at the top of the page, fewer users feel the need to click through to the source websites that supplied the underlying information.
Why the Numbers Diverge
The gap between a 61% and a 70%-plus decline likely reflects differences in methodology, query selection, and time frame rather than a contradiction. Seer Interactive's figure is grounded in a large, multi-organization dataset spanning informational queries specifically, tracked over more than a year 1. The second report appears to focus more broadly on publisher-level impact tied to the initial 2024 launch of AI Overviews across industries 2. Informational queries — the kind most likely to be fully answered by an AI summary without requiring a click — are also the category most vulnerable to this effect, which may explain why both figures are unusually high compared to typical search volatility.
Why It Matters
For publishers, marketers, and SEO professionals, the implication is the same regardless of which exact percentage is most accurate: organic click-through rates for content that AI Overviews can easily summarize are collapsing. This has direct revenue consequences for ad-supported and traffic-dependent media businesses, and it is forcing a rethink of search strategy heading into 2026, including calls for new tactics aimed at maintaining visibility even when Google's AI answers the question before a user ever reaches the results list 1.
The Bigger Picture
Together, the two reports underscore that AI Overviews represent one of the most consequential shifts in search behavior in years. As Google continues expanding AI-generated answers across more query types, the pressure on organic traffic — and the businesses built around it — is likely to intensify rather than ease.
