Google already ran this experiment. It reported that hotels lost more than 10% of traffic and intermediaries lost almost none.

Google rolled out a redesigned search results page across the European Union on 8 September 2026, after the European Commission fined it €460 million on 23 July for favouring its own shopping, hotel, transport and sports results and gave it 60 days to stop. Two years earlier, Google ran a controlled version of roughly this change in Germany, Belgium and Estonia, and published what happened.

This piece is for hoteliers working out what the remedy does to their free route into Google, and for operators outside the European Economic Area reading it as a preview. The most useful evidence available is a test Google ran on its own, which cuts both ways.

The 2024 test measured the thing everyone is now speculating about

In November 2024, Google announced it would test removing hotel features in three European Union markets, reverting to something close to its original ten-blue-links format. Oliver Bethell, its competition legal director, wrote at the time that the test would remove the map showing where hotels are and the hotel results underneath it, and that the company was reluctant to take the step.

The test ended in December 2024. Bethell reported the outcome in a statement: people were measurably less satisfied, took longer to find hotels, ran more searches and more often gave up. Then the part that matters commercially. Traffic to hotels and intermediary sites both fell, hotels lost the most at more than 10%, hundreds of thousands of European hotels were affected, and traffic to intermediary sites stayed largely flat.

That is a measured asymmetry, not a prediction. Removing the layer cost hotels roughly ten times what it cost the intermediaries, in Google's telling.

Every number describing the harm belongs to Google, and Google was negotiating at the time

The caveat is as important as the finding.

Google produced these figures during an open non-compliance investigation, while arguing to the Commission that the remedies its rivals wanted would damage the businesses those rivals claimed to be protecting. The same blog post carried a separate claim that direct booking clicks to airlines, hotel operators and small retailers had fallen by around 30% since the earlier DMA changes. No independent party has verified either figure, and Google has not published the methodology.

The counterparties dispute the framing. More than 20 price comparison websites publicly criticised Google's proposal in late 2024, saying their feedback had been ignored and that regulators should charge the company with non-compliance. The Commission agreed with them on the substance in July 2026, finding that Google displays its own services more prominently than third parties and fining it accordingly.

So there are two defensible readings. Either the remedy transfers traffic from hotels to intermediaries while helping nobody, which is Google's account supported only by Google's data. Or Google built an unlawful advantage into the page, the removal is the correction, and the traffic Google says hotels lost was traffic obtained through self-preferencing in the first place. The published evidence does not settle it.

What shipped in September is not the ten blue links

The 2024 test was temporary and results reverted. The design that went live on 8 September 2026 is different and worth describing precisely, because the trade coverage has largely blurred the two.

GOOGLE EU SEARCH, TRAVEL QUERIES, FROM 8 SEPTEMBER 2026
├── One specialised search engine placed at the top of the page
├── Two further rival services below, with fewer details
├── Below those, a carousel of hotels, airlines or restaurants
├── Real-time prices removed from that carousel
└── Ranking within the structure still set by Google's algorithm

The map was the subject of the 2024 experiment. What the September design removes from the hotel carousel is live pricing. For a property whose free booking link carried a rate into that surface, the rate is what has gone.

Google also removed its dedicated vacation rental search unit across the European Economic Area on 8 September, ending a commission-free comparison route for short-term rental operators outright rather than degrading it. That is the sharper precedent for hoteliers: when a free direct unit becomes a compliance problem, removal is on the table, not only redesign.

Nick Fox, Google's senior vice-president for knowledge and information, told Reuters the changes degrade the experience for Europeans and boost online intermediaries at the expense of local businesses. Google says the changes apply inside the European Union only.

Operators outside the European Economic Area are reading a roadmap, not a foreign story

United Kingdom users sit outside the European Economic Area and do not see the September design. The Digital Markets, Competition and Consumers Act is already law rather than a proposal, and the Competition and Markets Authority has been consulting on ranking and choice remedies for Google under its strategic market status regime, so the direction of travel is set even though the specific remedies are not.

For American operators the split is now visible in both directions. Google launched hotel booking inside AI Mode on 27 August 2026 with ten partners, in the United States and in English, and excluded the European Economic Area. Two weeks later it stripped live pricing out of the European travel carousel. European hoteliers are losing a free discovery surface at the same moment they are being left out of the new transactional one, and the second exclusion has the same regulatory cause as the first.

Some operators are responding by pulling their own Google Business Profile and free booking link data into view and checking what actually renders on a European query today, on the reasoning that a surface they cannot see is one they cannot plan around. Others are treating the whole thing as a negotiation still in progress and waiting, since the 2024 test reverted and this design may too. Either way the underlying dependency is the one half of UK travellers now bring to trip planning, and it is being rearranged by a regulator rather than by the market.

The unresolved question is the one the Commission's decision does not reach. It addresses ranking in classic search results. How the same non-discrimination obligation applies to AI Overviews and AI Mode, where Google decides what a traveller sees without a ranked list at all, has not been tested by anyone.
