Google Forced to Restructure EU Search to Show Rival Results

Full analysis

Google just told Reuters that the EU forced "the largest reduction in quality of service at the world's most popular internet search engine in its 29-year search history." That is a company complaining that it now has to show you Expedia before it shows you its own paid box. What's actually being decided here is who owns the click on a high-intent query. Not just in travel, not just in the EU.

The change is hard for Google to undo. It comes from a court and a €460 million fine in July, under the Digital Markets Act, the EU law that forces big platforms to compete fairly. The deadline is already set: Google has to comply now. What's genuinely open is whether the behavior of users and budgets actually shifts, or whether Google engineers its way back to the same yield within a year.

The Market Analyst. For the ad-tech operator, the interesting money question is where Google's lost yield lands. If rival results sit above Google's own sponsored units on EU travel and shopping queries, the premium Google charged for that top slot compresses. That budget clears somewhere. Travel-heavy DSPs (the software that lets advertisers buy ads across the open web) and retail media networks are the natural catch basins. For an informed outsider: when the biggest toll booth on the internet is forced to let cars take another road, whoever built the other road gets paid. The catch is timing. This shows up as a slow drip in buy-side models over two or three quarters, not a Q4 catalyst.

The Skeptic. Google's framing is self-serving, but so is the celebration. This touches EU query volume in verticals where people already comparison-shop. Booking.com and Expedia still have to convert the click, and their conversion machinery is not obviously better than Google's. The EU has a weak record on behavioral remedies. Google spent years wrapping revenue moves in user-benefit language, AMP being the clearest case. Give the engineers 18 months and they will find a compliant layout that still favors Google-adjacent signals. For an outsider: the fine is real, the behavior change is a promise. Anyone treating the €460 million as proof the moat cracked is anchored to the penalty. The outcome is a different question entirely.

The Operator. Anyone running Google Shopping or travel and hospitality clients needs to audit search strategy now. Rival results above sponsored units means CPCs (the price per click) move on branded and category terms. Yield compresses on the queries that used to command premium placement. The bigger break is the funnel. Retargeting flows built on a Google-owned journey, search to Google Hotel Ads to conversion, stop working the way they did. Teams on the Expedia and Booking side get organic-adjacent traffic they never had to pay for, which quietly poisons their attribution models within 90 days. For an outsider: the map ad buyers memorized just got redrawn, and the systems that measure success still think it's the old map.

The Strategist. The DMA is running a live experiment in whether you can pry apart Google's vertical search moat. If Booking.com and Expedia hold durable click-share on high-intent EU travel queries, that is proof the deep-vertical challenger works, and that proof walks straight into US antitrust discussions faster than anyone models. The two-year play is the aggregation layer. Whoever surfaces cleanly across the choice screens the EU now mandates owns a new slice of audience. Criteo-shaped players and retail media networks have been waiting for exactly this opening: monetize the click after Google lets go of it. For an outsider: the value is not in the traffic Google loses, it's in who catches it.

Here's where these views genuinely split. The Market Analyst and the Strategist see a structural door opening. The Skeptic says the door is painted on the wall. That disagreement comes down to one thing: does forced placement of rival results actually move user behavior, or do people scroll past the mandated links straight to the brand they know? Nobody has that data yet, because the remedy is days old.

The second tension is timing versus permanence. The Operator says the funnel breaks now, in weeks. The Skeptic says Google re-optimizes within 18 months. Both can be true. Operators eat disruption immediately and Google claws back yield slowly. The people who get hurt are the ones who assume the disruption is permanent and rebuild their whole stack around it.

What this hinges on: whether EU users click the rival results at a rate that shifts real click-share, and whether Google's compliant layout can quietly re-favor its own signals. The council leans toward disruption being real but temporary, and toward the money implication being slow and diffuse rather than a clean catalyst. Before anyone reallocates budget on this, watch the actual EU travel CPC data over the next two quarters and watch how Google's SERP layout evolves. Don't rebuild a funnel around a remedy that Google is already engineering around.

Prediction: Booking Holdings will spend the same share of its revenue on marketing in the first half of 2027 as it did in the first half of 2026, or a larger share, when it reports second-quarter results in August 2027.

Confidence: Medium

Why: The EU's Digital Markets Act, the law forcing large platforms to give rivals fair access, has made Google place travel sites above its own paid boxes on European searches, and Google paid a 460 million euro fine in July over the same conduct. If that placement genuinely hands Booking free, high-intent traffic, the cleanest evidence is Booking needing to buy less of it: marketing has run near 30% of its revenue in recent years, and a real windfall would push that ratio down. The likelier path is that European users scroll past mandated rival links to the brand and the format they already know, while Google keeps re-tuning a compliant layout that still favors its own units, leaving Booking bidding just as hard for the same clicks. Booking also has a standing habit of pushing every efficiency gain back into paid acquisition to defend share against Expedia and Airbnb, which works against the ratio falling even if free traffic rises. A drop in that share would be the strongest sign yet that a layout remedy can actually pry a click away from Google.

Revisit by 2027-08-15: We're right if Marketing expenses as a percentage of revenue for the six months ended June 2027, in Booking Holdings' August 2027 results, are equal to or higher than the same measure for the six months ended June 2026. We're wrong if That percentage is lower than the same measure for the six months ended June 2026.
