Google’s AI answers reduced Wikipedia search visits, study finds
- A University of Washington study found that English Wikipedia saw a search referral drop of roughly 5% following the rollout of AI Overviews.
- Researchers compared English traffic trends against French and German counterparts to estimate the causal impact of the feature.
- The study notes that individual page-level impact remains unclear, as researchers could not track which specific searches triggered an AI citation.
Marketers should prepare for a potential mid-single-digit decrease in informational search traffic as AI answers satisfy user queries directly on the search results page.
