We estimate the impact of Google's AI Overviews (AIO) on Wikipedia's search traffic using AIO's staggered geographic rollout and Wikipedia's multilingual structure. Our difference-in-differences design compares monthly external-search referrals to English Wikipedia articles with referrals to the same articles in German and French, and finds that default AIO availability reduced English search traffic by 5.45% and 4.82%, respectively. Our results suggest that answer-producing digital intermediaries can materially reallocate attention away from informational publishers, with implications for content monetization, search platform design, and policy.\n    \n\n## Submission history\n\nFrom: Mehrzad Khosravi [\n[view email](https://arxiv.org/show-email/b75349c8/2602.18455)]\n\n**Thu, 5 Feb 2026 01:31:44 UTC (1,474 KB)**\n\n[\\[v1\\]](https://arxiv.org/abs/2602.18455v1)\n**Thu, 26 Mar 2026 01:10:28 UTC (1 KB)**\n\n[\\[v2\\]](https://arxiv.org/abs/2602.18455v2)\n*(withdrawn)*\n\n**Fri, 17 Apr 2026 20:18:13 UTC (1,488 KB)**\n\n[\\[v3\\]](https://arxiv.org/abs/2602.18455v3)\n**Tue, 12 May 2026 07:35:59 UTC (1,488 KB)**\n\n[\\[v4\\]](https://arxiv.org/abs/2602.18455v4)\n**Wed, 26 Aug 2026 07:40:54 UTC (51 KB)**\n\n[\\[v5\\]](https://arxiv.org/abs/2602.18455v5)\n**[v6]** Wed, 2 Sep 2026 20:53:31 UTC (1,812 KB)\n\n### References & Citations\n\nLoading...\n\n# Bibliographic and Citation Tools\n\nBibliographic Explorer \n\n*(*[What is the Explorer?](https://info.arxiv.org/labs/showcase.html#arxiv-bibliographic-explorer))\nConnected Papers \n\n*(*[What is Connected Papers?](https://www.connectedpapers.com/about))\nLitmaps \n\n*(*[What is Litmaps?](https://www.litmaps.co/))\nscite Smart Citations \n\n*(*[What are Smart Citations?](https://www.scite.ai/))\n# Code, Data and Media Associated with this Article\n\nalphaXiv \n\n*(*[What is alphaXiv?](https://alphaxiv.org/))\nCatalyzeX Code Finder for Papers \n\n*(*[What is CatalyzeX?](https://www.catalyzex.com))\nDagsHub \n\n*(*[What is DagsHub?](https://dagshub.com/))\nGotit.pub \n\n*(*[What is GotitPub?](http://gotit.pub/faq))\nHugging Face \n\n*(*[What is Huggingface?](https://huggingface.co/huggingface))\nScienceCast \n\n*(*[What is ScienceCast?](https://sciencecast.org/welcome))\n# Demos\n\n# Recommenders and Search Tools\n\nInfluence Flower \n\n*(*[What are Influence Flowers?](https://influencemap.cmlab.dev/))\nCORE Recommender \n\n*(*[What is CORE?](https://core.ac.uk/services/recommender))\n# arXivLabs: experimental projects with community collaborators\n\narXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.\n\nBoth individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them.\n\nHave an idea for a project that will add value for arXiv's community?
