Google is changing the way travel-related search results appear across Europe after regulators found that its treatment of competing services breached the Digital Markets Act, moving one of Brussels’ most consequential platform cases from legal enforcement into the design of a product used to direct customers towards hotels, airlines, retailers, and comparison services.

The changes will give third-party comparison services greater prominence, while direct listings from hotels, airlines, and other suppliers will remain available through redesigned result formats. They follow the European Commission’s July finding that Google had favoured its own specialist services in Search and its €460 million penalty for the infringement.

Under the DMA, designated gatekeepers cannot rank their own services more favourably than comparable third-party offerings and must apply fair and non-discriminatory conditions. The Commission concluded that Google had given its own shopping, hotel, transport, and sports services advantages through placement and presentation that competitors could not obtain on equivalent terms.

Although the immediate remedy concerns page design, the commercial consequences reach further because search visibility influences how customers arrive at businesses and how much those businesses pay to acquire them. Hotels, airlines, retailers, and other suppliers have an obvious interest in preserving direct traffic, while comparison platforms depend on prominent placement to justify their own role between supplier and customer.

Search visibility becomes a regulated asset

Comparison services have argued for years that Google can use its control of general search to favour specialist products that compete with companies relying on the same search engine for distribution. The DMA gives the Commission a more direct route to challenge that behaviour because its gatekeeper obligations apply in advance rather than requiring every competitive effect to be reconstructed through a new antitrust case.

Direct suppliers face a different risk, however, because a remedy designed to strengthen intermediaries can make those intermediaries more important to the businesses ultimately selling the hotel room, flight, or product. Direct bookings can reduce commissions, preserve more control over the customer relationship, and give suppliers greater access to first-party information, whereas a shift towards comparison services can increase another form of dependency even if Google’s own advantage is reduced.

Google has argued that earlier DMA-driven changes damaged direct traffic and made some search journeys less useful, particularly in travel. The company has a clear commercial interest in retaining discretion over product design, but the objection exposes a genuine regulatory problem: removing one bottleneck does not guarantee that the resulting market becomes more balanced if traffic simply concentrates around another set of intermediaries.

The practical test will therefore be visible in traffic patterns rather than screenshots. Comparison services will look for stronger referral volumes, direct suppliers will monitor bookings that reach their own websites, and regulators will need to distinguish genuine redistribution of opportunity from changes that satisfy the formal rule without materially altering market power.

The DMA moves into product architecture

Europe’s platform regime is entering a more operational phase as enforcement moves from gatekeeper designation and fines into ranking systems, interfaces, contractual terms, and the routes through which customers reach businesses. These interventions are harder to evaluate than a financial penalty because a design can be compliant on paper while still creating disputed commercial outcomes.

The problem is becoming more complicated as generative AI changes search itself. Systems that answer queries directly can reduce the number of users clicking through to external sites, while publishers, retailers, travel companies, and other businesses may become more dependent on how models select, summarise, or cite third-party information.

That development widens the same competition question already visible in conventional search: when one platform controls the interface through which users discover information, the placement rules applied inside that interface can determine which businesses receive attention and which become invisible. Regulation consequently has to keep pace not only with existing search layouts but with a product category that is itself changing quickly.

Techopia’s earlier examination of Google’s DMA penalties showed how Brussels is moving beyond broad principles and into specific commercial practices. The redesigned travel results extend that process into one of the clearest tests yet of whether European gatekeeper rules can alter distribution without making the search experience less useful or transferring dependence somewhere else.

Google will now operate the revised formats under sustained scrutiny from regulators and businesses measuring their own traffic. Whether the remedy works will depend less on where individual boxes sit on the page than on who ultimately reaches the customer, on what terms, and whether those terms become meaningfully less dependent on a dominant platform.
