Google has rolled out sweeping changes to its search results across Europe, warning that the overhaul marks the largest reduction in quality in the company's 29-year history. The changes, designed to satisfy the EU's Digital Markets Act (DMA), give greater prominence to price comparison platforms such as Expedia and Booking.com over individual hotels, airlines, and restaurants listed directly in search results. Google says earlier DMA-related adjustments already caused a 30% drop in free direct-booking traffic to European businesses, and that user testing of the latest changes showed high dissatisfaction — with users forced to retype queries to find what they need. The revisions follow a €460-million fine issued by the European Commission in July for Google favouring its own services in search results, with regulators threatening periodic penalties of up to 5% of global turnover for non-compliance. Google has now accumulated over €10 billion in total EU antitrust fines across nearly two decades of regulatory disputes.
