AI Overviews quietly tank publisher traffic and UX
Google’s AI search cuts publisher clicks by 20%—but users see zero benefit
A preregistered field experiment led by Stephanie T. Wang and four co-authors used Google Search with real users to quantify the side-effects of generative AI in search. In a sample of 1,100 participants, turning off AI Overviews and AI Mode increased publisher click-through rates by roughly 20 %, directly counter to the platforms’ stated goals.
When AI Mode was left on, users clicked 8 % fewer links overall and reported lower trust in the information returned. The study, published on arXiv (2608.18352), traces how AI-generated summaries reroute attention, diverting ad and subscription revenue from publishers that sustain the open web. It is the first causal evidence linking Google’s AI push to measurable harm on both user experience and the broader information economy.
- 1,100-person field experiment on Google Search quantified AI Overviews’ impact
- AI Mode reduced publisher clicks by 8 % and eroded user trust metrics
- Removing AI features boosted publisher click-through rates by ~20 %
Why It Matters
AI search features are quietly siphoning revenue from publishers without improving user outcomes, threatening the sustainability of the open web.
