Google Must Share Its Search Data. Good.

The European Commission just adopted a binding decision that reshapes how search data works. Not a recommendation, not a polite suggestion. A legal requirement with deadlines, conditions, and consequences.

Under the Digital Markets Act, Google must share anonymized search data with rival search engines and AI chatbots. Not the algorithm (that stays proprietary), but the data: what people search for, where they click, what results they see, in what order. Real data, anonymized for privacy, available to qualified competitors.

A recent report on Search Engine Journal breaks down the ruling in detail. We looked at what it means for digital marketing strategy.

What the ruling actually requires

The ruling comes under the Digital Markets Act (DMA), the European regulation that treats major digital platforms as public infrastructure. Google tried the voluntary route: offering limited data access on request. The Commission concluded that approach wasn't working and moved to binding terms.

The data package includes: anonymized search queries, URLs displayed in results, positions, clicks, views, and metadata like language and device type. Essentially everything a marketer gets from Google Search Console, but for the entire market, not just their own site. Think of it as access to the competitive intelligence that Google held exclusively until now.

What's NOT included: the ranking algorithm, personal data, search history, or rare and unusually long queries that could identify users. Data goes through security screening and independent audits before sharing. Google must propose a pricing model for data access by January 2027.

Who qualifies: search engines and AI chatbots functioning as search engines with at least 50,000 monthly EU users. New providers must pass either a two-year operating history test or an investment test. The condition: data can only be used to improve search results, not to train general-purpose AI models.

Why marketers should pay attention

In the short term, the impact is limited. AI chatbots account for approximately 0.24% of global internet traffic. Bing holds under 4% market share in Europe. Nobody is dethroning Google tomorrow.

But the short term isn't where the game is being played. In the medium term, three things shift fundamentally.

Alternative engines get better data. Until now, Bing, DuckDuckGo, and Brave Search operated with their own limited datasets. With access to real Google search data, they can improve result relevance significantly. Better results mean easier user migration. We've already seen how search behavior is changing, and this ruling accelerates that trend. The difference now is that migration will no longer depend solely on user preference but on the objective quality of alternatives.

AI chatbots get real grounding. Perplexity, ChatGPT Search, Gemini: they all share one problem. Their web data is incomplete, sometimes outdated. Access to Google's search data lets them build more precise, more current responses. A chatbot that delivers better answers attracts more users. The cycle reinforces itself. An important detail: the ruling specifies that data can be used for grounding (anchoring responses in recent web data) but not for training base models. This means AI answers become more factual without the models themselves becoming copies of Google.

The monopoly on intent fragments. Google has been the only entity that truly knew what people search for. Not just what they type, but what they do next: where they click, how long they stay, what they abandon. That data was the ultimate competitive advantage. Now, part of it becomes available to competitors. That's enough to reshape how search traffic dynamics work across the board.

A view from the EU frontline

We operate from Romania, an EU member state where Google holds over 95% search market share. Alternatives practically don't exist in users' consciousness. That makes any fragmentation of the monopoly disproportionately impactful: from a 95% baseline, even a 5-10% migration to alternatives means a significant volume of redistributed traffic.

For agencies and marketers operating in Europe, this creates a strategic window worth paying attention to. Those who start optimizing for alternative engines now, while the competition isn't even looking in that direction, gain visibility at zero additional cost. It's exactly the situation we saw with GEO (Generative Engine Optimization) a year ago: early movers captured an advantage that's been difficult to catch up to.

What to do with this, practically

If you're a marketer or business leader, three things deserve attention now.

Visibility diversification becomes urgent. Not tomorrow, but within 2-3 years. If your search strategy means exclusively Google, you're losing ground that competitors just gained access to. Bing, Perplexity, AI chatbots with search capabilities: they'll all have better data and will attract users from your segment. Monitoring visibility across these platforms is no longer optional. The tools already exist (BrightEdge, Semrush, and others track Bing and AI engine citations). The question isn't whether to start, but how fast you can build the muscle.

Quality content wins on multiple fronts. When a single search engine decides who's visible, you can optimize specifically for it. When multiple engines evaluate content using the same underlying data, real quality makes the difference. An article that clearly answers a question, with specific data and an original perspective, will perform well regardless of which engine evaluates it. We covered a related angle in our piece on SEO metrics no longer telling the full story.

Google doesn't disappear, but becomes one player among several. This is the hardest part to accept. Two decades of data monopoly created a reflex: search equals Google. The EU says that's no longer acceptable. And they have the legal tools to enforce it. Kent Walker, Google's Chief Legal Officer, stated the decisions "risk undermining vital privacy and security guardrails." Translation: Google disagrees, but complies. The Commission has announced it will review these measures every two years and may reopen them if testing shows the anonymization isn't sufficient.

The change won't happen overnight. Deadlines run through 2027-2028, implementation will be gradual, and Google will push back where it can. But the direction is clear. Those who prepare now will have a real advantage when the market opens up for real.
