Do AI Overviews Benefit Search Engines? An Ecosystem Perspective

2026-01-30

AI Summary

While AI Overviews enhance user experience, they divert traffic from content creators, potentially discouraging high-quality content production and undermining the long-term profitability of search engines. This work addresses this challenge by proposing the first ecosystem-oriented game-theoretic model of creator competition to analyze the long-term impacts of AI Overviews on content creation and platform revenue. Building on equilibrium analysis, we design a theoretically grounded and practically feasible citation and compensation mechanism. Empirical evaluation using real-world click-through data demonstrates that our mechanism significantly improves the platform’s long-term profit across diverse realistic scenarios, offering a sustainable pathway for AI-augmented search ecosystems.

Abstract

The integration of AI Overviews into search engines enhances user experience but diverts traffic from content creators, potentially discouraging high-quality content creation and causing user attrition that undermines long-term search engine profit. To address this issue, we propose a game-theoretic model of creator competition with costly effort, characterize equilibrium behavior, and design two incentive mechanisms: a citation mechanism that references sources within an AI Overview, and a compensation mechanism that offers monetary rewards to creators. For both cases, we provide structural insights and near-optimal profit-maximizing mechanisms. Evaluations on real click data show that although AI Overviews harm long-term search engine profit, interventions based on our proposed mechanisms can increase long-term profit across a range of realistic scenarios, pointing toward a more sustainable trajectory for AI-enhanced search ecosystems.
