Google Claims EU's DMA Changes Caused Unprecedented Search Quality Degradation

Google has declared that the recent adjustments to its search results within the European Union, necessitated by the Digital Markets Act (DMA), have triggered the most significant decline in search quality the company has ever experienced across its 29-year operational history. A Google official communicated to Reuters that these modifications represent the "largest reduction in quality of service" for the world's leading internet search engine. Google's assessment is that these mandated changes have inadvertently elevated the prominence of price comparison sites, also known as vertical search services (VSS). These VSS are particularly prevalent in sectors such as hospitality, travel, and dining, with prominent examples including major online travel agencies like Expedia and Booking.com. The company argues that these specialized platforms now benefit from greater visibility in search results, overshadowing businesses within the same industries that are primarily listed with only basic contact information and website links. The newly implemented search result format is designed to prominently feature one specialized search engine at the apex of the page. This is followed by two additional VSS entries, albeit with less detailed information. Beneath these, a carousel display will showcase offerings from hotels, airlines, and restaurants, but critically, will omit key real-time data such as pricing. The ranking of entities within these carousels will continue to be governed by Google's established search algorithms. This situation is the culmination of an extended period of negotiation and contention between Google and the European Commission concerning the implications of the DMA. Google had been actively proposing alterations to its search interface to comply with the legislation, and these changes were tested throughout 2024. The company's current assertion of a quality degradation is therefore not unexpected, given its prior testing and ongoing engagement with the regulatory body. While these DMA-driven changes are geographically confined to European search queries, this region represents a substantial segment of Google's global user base. Google has publicly stated its reluctance to implement these specific changes, indicating it was compelled to do so by the European Commission's directives. The ultimate impact on the end-user's ability to find relevant and high-quality information through Google Search in the EU remains a subject of ongoing scrutiny and debate within the digital landscape.
