A broad coalition of European travel, retail and digital services is intensifying pressure on Brussels to crack down on Google’s search practices, urging the European Commission to strictly enforce the Digital Markets Act against what they describe as persistent self-preferencing in search results.

Coalition Targets Google’s Treatment of Rival Services

The latest joint statement from industry groups representing comparison shopping sites, online travel platforms and consumer-facing brands argues that recent Google changes to search do not resolve long-running concerns about how rival services are displayed. Publicly available documents from retail and commerce associations in Europe indicate that the coalition contends Google’s current layouts and rich results still push its own specialist offerings ahead of competitors in areas such as shopping, hotels and flights.

The groups point to a history of enforcement in Brussels, including the 2.4 billion euro penalty upheld by Europe’s top court for favouring Google Shopping, as evidence that preferential ranking of house services can significantly distort traffic flows and advertising revenue for rivals. They maintain that, under the Digital Markets Act, such conduct should now be addressed through faster, rule-based intervention rather than years-long antitrust probes.

According to published coverage, the coalition warns that if Google’s current approach to search is allowed to stand, independent vertical search engines and comparison sites could see further declines in visibility. For travel businesses in particular, which rely heavily on appearing prominently for destination, hotel and flight queries, any demotion can quickly translate into fewer bookings and higher customer acquisition costs.

Industry stakeholders have therefore called on the European Commission to use the new powers available under the Digital Markets Act to require concrete design changes that ensure rival services are treated on equal terms in general search results pages across the European Union.

Digital Markets Act Becomes Central Enforcement Tool

The Digital Markets Act, which began applying to designated “gatekeepers” such as Alphabet’s Google Search in 2024, prohibits self-preferencing and requires platforms to apply fair, reasonable and non-discriminatory conditions to business users. Official guidance from EU institutions explains that gatekeepers are barred from ranking their own services more favourably than equivalent third-party offerings when users search for goods, services or content.

Reports indicate that the European Commission has already opened non-compliance investigations into Google over search-related practices, focusing on how its vertical services like Shopping, Flights and Hotels appear within general search results. Preliminary findings published in recent months have raised concerns that some of Google’s proposed remedies, including tests that placed greater emphasis on traditional “blue links,” may not fully deliver on the objective of strengthening competition from independent providers.

Legal analyses of the Digital Markets Act note that infringement can lead to fines of up to 10 percent of a company’s global annual turnover, and higher penalties for repeat violations. This elevates the stakes for Google’s search product not only in desktop and mobile browsers, but also in travel-specific user journeys where hotel and flight modules have become increasingly prominent.

For the travel sector, the shift from purely competition-law enforcement to a regulatory regime with clear obligations is seen as a chance to secure quicker adjustments. Travel platforms argue in public commentary that the DMA framework could rebalance visibility between integrated search features and independent booking or comparison sites, particularly on high-value queries linked to accommodation and transport.

Travel and Retail Sectors Warn of Impact on Visibility

European travel businesses have long contended that Google’s rich search interfaces make it harder for users to discover alternative providers. When travellers search for hotels in a city or flights between major hubs, they are often presented with Google-branded modules at the top of the page, along with map panels and other widgets. Industry statements claim these features capture a growing share of user attention before people scroll to organic links for independent booking platforms or comparison services.

Publicly available submissions from retail and commerce associations highlight similar dynamics in product search, where Google Shopping units display images, prices and merchant links above standard results. Comparison Shopping Services say they effectively compete for the same users but appear further down the page, resulting in lower click-through rates and diminishing returns on marketing spend.

In both travel and retail, the coalition argues that these design choices concentrate traffic and transaction data within Google’s own ecosystem. That, in turn, can influence how advertising tools and algorithms evolve, giving additional advantages to services that are already closely integrated with the search engine’s commercial offerings.

For smaller travel companies, local accommodation providers and niche tour operators, reduced visibility on general search pages may mean greater dependence on paid placements or intermediaries. This risk is central to the coalition’s call for strong enforcement of the DMA’s self-preferencing ban, which they argue is necessary to preserve diversity and innovation in Europe’s tourism and retail landscapes.

Commission Scrutiny Intensifies as Remedies Debated

The European Commission’s competition and digital policy teams have signalled that they will measure compliance with the Digital Markets Act by looking at real-world outcomes for business users and consumers. According to analysis published by legal and policy observers, officials are expected to examine whether rival services gain more meaningful opportunities to appear in prominent positions and whether traffic patterns become less dependent on Google’s proprietary modules.

Reports from European media and technology outlets note that Google has put forward several rounds of design proposals to address concerns, including changes to how links to third-party providers are displayed around its own specialist units. Industry groups, however, describe these adjustments as incremental and argue that they fall short of the structural separation required to guarantee equal treatment in rankings and presentation.

Debate now centres on what an acceptable remedy should look like in practice. Some commentators advocate for clearer visual separation between Google-branded units and rival services, while others suggest that neutral choice screens or standardized comparison blocks could give users a more balanced overview of travel and shopping options. The coalition pressing for stricter enforcement maintains that any solution must be tested against robust data on visibility and clicks, not only against design principles.

With ongoing probes under the DMA and parallel antitrust activity in other jurisdictions, Google’s approach to search is likely to remain under sustained scrutiny. For Europe’s travel and retail sectors, the coming enforcement decisions may shape how easily customers can discover independent platforms when planning trips, comparing prices or booking accommodation across the single market.
