Google is changing the visual hierarchy of European search results in one of the clearest examples yet of regulation directly reshaping the search interface. Under a new Digital Markets Act compliance rollout, specialized comparison engines can appear above the hotels, airlines, restaurants and other direct businesses users might previously have encountered more prominently in Google's own rich results.
According to Reuters reporting on September 8, the redesigned results highlight one vertical search service at the top of the page, followed by two additional services presented with fewer details. A carousel containing direct hotel, airline or restaurant results can then appear below those intermediaries, but some of the information that made Google's rich results useful for immediate comparison—including real-time prices—is being removed.
The change is a product consequence of the EU's attempt to stop Google from using its control of general search to favor its own specialized services. But it also creates a new competitive problem for the businesses that depend on Search. A hotel can now find itself visually downstream from comparison engines such as Booking.com or Expedia even when the user's underlying intent is to find accommodation rather than a comparison website.
Google says the redesign will make Search worse for European users and more expensive for businesses. EU regulators see the tradeoff differently: some friction is acceptable if it prevents a dominant gatekeeper from deciding that its own vertically integrated services deserve the most powerful positions and features.
The DMA is changing who gets the most valuable space on Google
The Digital Markets Act does not tell Google exactly how every search result must look. It establishes obligations for designated gatekeepers, including restrictions on favoring their own services over comparable third-party services.
The European Commission lists Google Search as one of Alphabet's designated core platform services. Article 6(5) of the DMA is particularly relevant to the current dispute because it prohibits gatekeepers from treating their own services more favorably in ranking and related indexing and crawling.
Google has already made more than 20 changes to European Search in response to the law. Those changes have included dedicated units and filters for comparison sites, changes to Google Flights and Maps integrations, and additional opportunities for vertical search services to appear in categories such as travel and shopping.
The September 2026 rollout goes further by altering the order and information density of important commercial search results. That makes the DMA visible not as an abstract antitrust rule but as a change ordinary users can see when searching for a hotel, flight or restaurant.
A specialized search service can now occupy the top position
Reuters reports that the redesigned interface places one specialized search engine at the top of the page, with two additional vertical search services following it in less detailed formats. Google's algorithm determines the ranking among those services.
For travel searches, vertical search services can include intermediaries such as Booking.com and Expedia. These companies do not operate the hotel or airline the user eventually purchases from; they aggregate, compare or facilitate access to offers from many suppliers.
The regulatory rationale is straightforward. If Google can use the top of its dominant general-search product to display its own specialized hotel, flight or shopping experience with richer functionality than competing vertical search engines receive, those competitors can argue that they never get a realistic opportunity to compete for the user's next click.
The new layout gives those competitors a more visible route into the journey. But that route can also push the underlying hotel, airline, merchant or restaurant farther down the page.
Direct businesses are caught between Google and the comparison engines
This is what makes the DMA search dispute more complicated than a simple Google-versus-regulator story. There are at least three economic interests competing for the same search session: Google, vertical intermediaries and the businesses that actually supply the product or service.
A hotel may prefer a direct booking because it can avoid or reduce intermediary commissions and control more of the customer relationship. A comparison engine benefits when the user visits its platform first. Google wants to offer a useful search experience while preserving its own ability to innovate in specialized search features.
The Commission's goal is to stop the gatekeeper from using its general-search dominance to unfairly privilege its own downstream products. Yet increasing the prominence of independent comparison services does not automatically increase direct traffic to local suppliers.
That is the tension at the center of Google's criticism. The company argues that regulation intended to create more competition between platforms can end up moving users from one intermediary—Google—to another intermediary rather than directly to the business they were searching for.
Hotel, flight and restaurant carousels are losing real-time prices
The second major change affects the information Google can present inside its own result modules. Reuters says carousels for hotels, airlines and restaurants will sit below the specialized search services with important features such as real-time prices stripped out.
Price information is particularly powerful because it lets a user compare options without opening another website. A hotel result with a current nightly rate is much more decision-ready than a result containing only a name, location and rating.
Removing that information makes the Google module less self-contained. Users may need to click into another service or perform additional searches to compare actual offers.
From a competition perspective, that can reduce the advantage of Google's vertically integrated interface. From a user-experience perspective, it introduces friction deliberately: the search page does less of the comparison itself.
Google calls this the largest reduction in Search quality in its history
Google's language about the rollout is unusually strong. The company told Reuters that the changes represent the largest reduction in service quality in Google Search's 29-year history.
Nick Fox, Google's senior vice president for Knowledge & Information, said the changes degrade the experience for Europeans by boosting online intermediaries at the expense of local businesses and removing features users rely on. Google says users outside the European Union will not be affected.
Those claims should be understood as Google's position in an active regulatory dispute. The company has a direct commercial interest in retaining flexibility over how its search results are designed, and the European Commission has repeatedly rejected the premise that Google's preferred integrated experience should automatically outweigh competition concerns.
The important factual development is not whether the new design is objectively “worse.” It is that compliance is now producing a materially different search product inside the EU from the one users see elsewhere.
The Commission accepts that DMA compliance can create friction
The European Commission does not deny that some DMA changes can make digital products feel less seamless. In its DMA review guidance, the Commission explicitly acknowledges that users may experience additional friction or need to make choices that gatekeeper platforms previously made for them.
The regulator's argument is that this friction can be justified if it gives users meaningful choice and reduces structural dependence on dominant platforms. A highly integrated interface may be convenient precisely because one company controls multiple layers of the journey.
That creates a fundamental policy tradeoff. Product designers optimize for reducing steps. Competition regulators sometimes need to reintroduce steps so competing providers have a chance to participate.
The European search results becoming less information-dense are therefore not necessarily an unintended side effect. Some loss of integration is inherent in separating a gatekeeper's general platform from its own downstream services.
Google says earlier DMA changes cut direct booking traffic by 30%
Google told Reuters that previous DMA compliance changes had already caused a 30% decline in free, direct booking traffic to European businesses. It expects the latest changes to hurt those businesses further.
The number is important because a 30% decline would represent a substantial change in customer acquisition for hotels and other suppliers that rely on unpaid Google traffic. But it needs careful attribution.
The 30% figure is a Google claim. Reuters reports it as a company statement, and the current reporting does not provide a complete public methodology showing the exact sample of businesses, countries, query types, baseline period or causal design behind the percentage.
Google has made similar claims during earlier DMA debates. In a November 2024 compliance update, it said hotel operators had reported free direct-booking clicks falling by as much as 30% after earlier changes. That historical wording also illustrates why the statistic should not be presented as an independently verified Europe-wide measurement.
The 30% figure is strategically powerful but methodologically incomplete
Traffic claims in regulatory disputes are difficult to interpret without a denominator. “Direct booking traffic” could refer to clicks from specific hotel modules, free booking links, organic results or a combination of surfaces. A decline among a selected group of hotels is different from a 30% decline across all European accommodation businesses.
Causality is another issue. Search interfaces, travel demand, paid advertising, hotel pricing and intermediary strategies can all change simultaneously. A robust estimate of the DMA's effect would need to isolate the impact of the compliance design from those other variables.
None of this means Google's figure is wrong. It means the appropriate editorial phrasing is that Google says its earlier DMA changes reduced free direct booking traffic by 30%, not that the DMA has independently been proven to have cut European business traffic by exactly that amount.
For SEO teams, the broader direction is more important than one disputed percentage. Google is explicitly warning that regulatory changes are redistributing clicks among intermediaries and direct suppliers. That redistribution is now becoming more visible in the SERP itself.
The EU recently fined Google over self-preferencing
The September redesign follows direct enforcement pressure. Reuters reports that Google was fined in July for favoring its own services in shopping, hotels, transport and sports results, with the Commission requiring the company to change its behavior or risk additional periodic penalties.
The European Commission's enforcement announcement says Google displayed its own services more prominently, including at the top of search results and through enhanced visual features and filters, while comparable third-party services did not receive equivalent prominence.
That description explains why the current design changes involve both position and functionality. Moving comparison services upward addresses prominence. Removing features such as real-time prices reduces the functional advantage of Google's own specialized modules.
From the Commission's perspective, equal competition cannot be achieved if a rival receives a plain link while Google's own service receives an interactive comparison interface occupying the most valuable part of the screen.
The SEO impact is bigger than a normal ranking update
Search marketers are accustomed to algorithm updates that change which page ranks first. The DMA rollout changes the architecture around those rankings.
A local business can retain the same organic relevance and still lose visibility because new intermediary modules occupy more space above it. A hotel can remain Google's preferred direct supplier result while the entire direct-supplier carousel moves below three comparison-service placements.
This means conventional position tracking can understate the impact. Being “number one” inside a module does not tell you how far down the physical page that module appears, how visually prominent it is or how many intermediary choices the user encounters first.
European SEO reporting will increasingly need pixel depth, SERP-feature tracking and click-share data alongside nominal rank positions.
Local businesses may need to compete twice for the same customer
The redesigned travel and local SERP can create a two-stage acquisition problem. A hotel must first compete for visibility in Google's direct results while also competing inside the comparison engines that Google now places above those results.
That increases the strategic importance of distribution. A business that historically optimized primarily for Google may need to monitor how it appears on Booking.com, Expedia and other vertical search services because those intermediaries can now occupy more prominent Google real estate.
For restaurants, the equivalent issue can involve reservation and review platforms. For flights, it can involve travel aggregators. For shopping, comparison-shopping services become another layer between product discovery and the merchant.
The irony is that regulation designed to reduce dependence on one dominant platform can increase the importance of being optimized across several intermediaries at once.
Vertical search optimization is becoming part of European SEO
This suggests a broader change in what “search optimization” means inside the EU. If Google is required to give vertical search engines more prominence, businesses need to understand the ranking systems of those verticals as well as Google's.
Hotel teams may need stronger listing completeness, pricing consistency, inventory feeds and review management across major travel platforms. Restaurants may need to maintain accurate menus, booking availability and business data across multiple local services. Merchants may need better product feeds for comparison engines.
This does not replace direct SEO. It adds a distribution layer. The goal becomes visibility across the services that Google itself is increasingly required to surface.
For agencies, this could create a new distinction between optimizing a website for Google and optimizing a business's overall presence across the search ecosystem that Google sends users into.
Removing prices can change user behavior in unpredictable ways
Real-time prices reduce search costs for users. Without them, a person searching for a hotel may need to click several services before learning whether an option fits their budget.
That additional friction could increase clicks to comparison sites because they become the fastest route to pricing. It could also increase direct website visits if users prefer to check the supplier themselves. Some users may simply reformulate the query, which Google says happened frequently in its testing.
The outcome will depend on interface design and category. A traveler choosing among dozens of hotels may value aggregation more than someone searching for one named restaurant. A user already loyal to a particular airline may bypass comparison altogether.
This is why the traffic consequences need empirical measurement after rollout. The visual hierarchy tells us where Google is creating opportunity, but it does not guarantee where users will ultimately click.
European and non-European SERPs are diverging structurally
Google says the new changes apply in Europe and will not affect users outside the EU. That creates another challenge for international SEO teams: the same query can now produce meaningfully different commercial interfaces depending on regulatory jurisdiction.
Localization has always affected search results, but the difference is increasingly legal as well as geographic. European users may receive fewer integrated Google features and more third-party comparison opportunities because the DMA changes what Google is allowed—or effectively required—to prioritize.
Testing from the United States can therefore become misleading for an EU campaign. Screenshots, rank trackers and automated audits need to use the correct market and location if they are intended to represent the actual European customer journey.
Global SEO strategy is becoming partly regulatory infrastructure strategy.
The DMA is turning SERP design into a competition-policy instrument
For years, changes to Google's search interface were mostly interpreted through product and SEO lenses. Did a new carousel improve discovery? Did a local pack reduce organic clicks? Did richer answers keep users on Google?
In Europe, interface design now has another explicit objective: creating competitive space for businesses that regulators believe Google's vertically integrated products can disadvantage.
That means the most efficient interface for the user is not necessarily the only policy goal. A result page that instantly compares prices through a Google-owned module may be convenient while simultaneously making it difficult for an independent comparison engine to compete.
The current redesign is an attempt to rebalance those objectives, and the disagreement between Google and the Commission reflects fundamentally different definitions of a successful search market.
For businesses, the key metric is no longer just Google traffic
The immediate temptation will be to measure whether organic traffic rises or falls after the new layout. That matters, but it captures only one part of the redistribution.
A hotel might receive fewer direct clicks from Google but more bookings through an intermediary. Its total demand could remain stable while acquisition costs increase because the intermediary charges commission. Another business might gain visibility through a comparison engine that it could never achieve directly in Google.
Teams therefore need to measure direct organic traffic, referral traffic from vertical services, paid acquisition, intermediary commissions and final conversion together. A shift from a free Google click to an intermediary booking is not simply a traffic loss; it is a change in distribution economics.
That is why Google's 30% claim, even if later independently validated, would not by itself describe the complete business impact. The relevant question is where those users went and what it cost businesses to acquire them there.
Google's European SERP is becoming a different product
The September rollout is significant because it moves DMA compliance from subtle labels and additional filters into the basic ordering of commercial search results. A specialized comparison engine can now sit above direct suppliers, additional vertical services follow it, and Google's own hotel, airline or restaurant modules lose information such as real-time prices.
Google argues that this is a degradation of Search and says previous compliance changes have already reduced free direct booking traffic to European businesses by 30%. That number remains a company claim without a complete publicly available methodology in the current reporting. The European Commission, meanwhile, argues that some additional friction is an acceptable cost of preventing a dominant gatekeeper from favoring its own services.
For SEO teams, neither side of that political argument changes the operational reality. The European SERP is being structurally reorganized. Ranking first inside a direct-business result may matter less if comparison engines occupy the positions above it, and the loss of real-time information can redirect the user journey toward intermediaries.
The next phase of European search optimization will therefore be about more than ranking on Google. Businesses will need to understand the entire distribution chain that the DMA is building around Google: general search, vertical search, direct websites and the economics of every click between them.
