Google's DMA Search Redesign in Europe: A Plan for Hotels, Travel and Retail

Since September 8, Google shows EEA searchers an aggregator unit and a supplier unit for hotel, flight, transport and product queries. What changed, who gains, and what to do now.

If you sell rooms in Paphos, seats on long-distance coaches, or products from an online store in Nicosia, the results page your customers see changed on September 8, 2026. For hotel, flight, long-distance train and bus, and product searches made in the European Economic Area, Google now places comparison and booking platforms in one unit and direct businesses in another, and it has taken real-time prices out of the carousels below them. Businesses that relied on free, direct clicks are most exposed.

What Google changed, and why

The trigger was regulatory. On July 23 the European Commission fined Google €460 million under the Digital Markets Act, finding that it gave its own shopping, hotel, transport and sports results more prominence than similar third-party services. The Commission gave Google 60 days to comply or risk periodic penalty payments of up to 5% of its total worldwide turnover. Google may appeal. The redesign went live across the EEA on September 8.

Reuters, citing Google, describes the new page: one specialized search engine highlighted at the top, two others below it with fewer details, and a carousel of hotels, airlines and restaurants underneath, with real-time prices stripped out. Google's algorithm decides the order.

These changes degrade the user experience for Europeans – boosting online intermediaries at the expense of local businesses, and removing helpful features people rely on every day.

Google also told Reuters the changes are the largest reduction in quality of service in its 29-year search history, and that earlier DMA changes had already caused a 30% drop in free, direct booking traffic to European businesses, with a similar effect expected this time. Treat those as claims from a company arguing against the rules it is complying with; no report we read offers independent data. In July, the Commission called the changes Google was then testing for free shopping, hotel and flight results "substantial progress towards compliance."

How the aggregator and supplier units work

Google's Search Central documentation sets out two units that appear together on these queries.

QuestionAggregator unitSupplier unit
Who appearsApproved Vertical Search Services, including online travel agencies, comparison shopping services, metasearch engines and directoriesDirect providers, such as individual hotels or airlines and brick-and-mortar businesses
How to get inExpress interest via Google's forms, one for hotels, flights and ground transport, one for comparison shopping servicesBe a direct provider whose website serves users in the EEA
Data requiredHotels by direct data feed; flights, trains and buses by real-time API; products via Google's comparison shopping routeNothing beyond crawling, though data feeds can enhance results
When it showsOne at a time, with the top-ranked provider expanded by defaultOnly alongside an aggregator unit

Three details matter most. The expanded aggregator can show photos, prices or star ratings, and users can switch providers, but by default the one ranked first gets the richest listing on the page. The supplier unit exists only when the aggregator unit does, so a direct business never has the dedicated space to itself. And Google's documentation does not explain how the top-ranked aggregator is chosen.

The winners are approved vertical search services that can feed Google live inventory, above all whichever one ranks first. Direct businesses keep a place on the page, but the carousel below the aggregators has lost its real-time prices.

Google's documentation scopes both units to people in EEA countries, and Google says users outside the EU will not be affected. Neither names the United Kingdom. Search Engine Journal contrasts EEA results with those in the US or the UK, implying the UK is unchanged, but check rather than assume. A UK business selling to travelers or shoppers in the EEA is affected either way, because the units depend on where the searcher is.

A plan for hotels, travel and retail businesses

Take a baseline while the old data is fresh

You already hold the before picture. Freeze it now.

  • In Search Console, export clicks and impressions for your hotel, route or product queries by country for the eight weeks before September 8, with EEA markets separated from the rest.
  • From your booking engine or store, record how much revenue arrived direct and how much through OTAs or marketplaces, and what that commission cost.
  • Screenshot the results for your ten most valuable queries from an EEA location, and repeat monthly.
  • Annotate September 8 in GA4 and every dashboard, so nobody mistakes a drop for a site problem.

Direct-booking SEO for the supplier unit

Google says a direct provider needs nothing beyond what it can crawl to appear in the supplier unit, so the work happens on your own site: indexable room, route and product pages, clean structured data, and a site that plainly serves EEA users, which Google lists as a condition. Google does not define serving; the safe reading is local languages, local currencies and booking that works from every market you target. Google links to hotel feed documentation, so ask your booking engine or channel manager whether it can supply one.

Hotel groups and retailers with category pages should also look at structured data carousels, a beta feature in the EEA that needs ItemList markup on a summary page pointing to at least three detail pages on the same domain. Crawlable, well-marked-up pages are also what AI search tools read, so this work overlaps with generative engine optimization.

Decide your aggregator posture

If the top of the page belongs to an intermediary, your listing there is part of your search presence. A hotel should check which OTAs and metasearch engines appear in the aggregator unit for its destination, and keep its content, photos and rates there complete and accurate. A retailer should find out which comparison shopping services show its products. If your business is itself a directory or booking platform, Google's forms are the route in, but approval also depends on maintaining the required feed or API and meeting Google's quality standards.

Rethink the paid search budget

Google's documentation for the two units does not mention ads. The Commission's July decision notes that Google is also testing changes to how it presents shopping ads, still under assessment, so retailers should watch EEA Shopping campaigns. The mechanism is simple. If free direct clicks fall on brand and destination queries, more bookings have to be bought, through brand-term paid search or as commission to an intermediary. Compare the cost per booking of each before moving money, and split EEA from non-EEA campaigns so the effect shows in reporting.

Expect the path to a booking to get longer and harder to see, the problem we covered in measuring marketing beyond the click. And plan for more: a Google Actions Center page says Google is updating results for local searches, such as dining, services and things to do, with aggregator and supplier units. It gives no launch date or region.
