EU antitrust regulators are asking publishers whether Google’s proposal to let them block the use of their content in AI search without affecting search rankings addresses competition concerns. The feedback could influence an ongoing investigation that may result in another substantial fine if the proposal is deemed insufficient. Google announced the opt-out in June and plans to roll it out globally, after the UK antitrust watchdog ordered a similar option. Publishers have complained that AI Overviews, summaries displayed above conventional search links, could reduce traffic and revenue. The EU questionnaire, issued in July with an August 28 response deadline, also sought views on Google’s planned integration of AI Overviews and AI Mode into one AI Search experience.
