The European Commission on Thursday set out how it wants Google to share search data with rival search engines as part of compliance with the bloc’s digital rules. In a statement, the EU executive said “Google should allow third-party search engines to access search data, such as ranking, query, click and view data, on fair, reasonable and non-discriminatory terms.” The move targets the data inputs that shape ranking and user outcomes, potentially affecting how competitors build and evaluate their own search services.
What the EU is requiring: access to specific search data types
According to the European Commission’s statement as reported by Tech-Economic Times, the core requirement is specific data-access expectations. The Commission said Google should allow third-party search engines to access search data including ranking, query, click, and view data.
Each of these data categories maps to a different part of the search pipeline:
- Ranking data relates to how results are ordered, which reflects relevance and performance.
- Query data reflects what users search for, which influences indexing, coverage, and evaluation.
- Click data captures user interaction signals, often used to assess satisfaction or refine relevance models.
- View data indicates what users were shown, which helps distinguish between what was presented and what was clicked.
The Commission anchored the requirement in specific terms: access must be provided on “fair, reasonable and non-discriminatory” terms. While the source does not provide operational details of how those terms would be measured, the phrasing indicates that the EU expects competitors to receive access structured to avoid preference toward Google’s own services.
Why data access matters for search technology
Search engines are data-driven systems: ranking and relevance depend on large-scale signals and continuous feedback from user behavior. By focusing on ranking, query, click, and view data, the EU’s position indicates that it views these signals as key inputs to search improvement.
From a technology standpoint, rival search engines could use the shared data to:
- Compare how different result sets are ordered (using ranking data).
- Assess coverage and demand patterns (using query data).
- Evaluate user engagement outcomes (using click data).
- Understand presentation versus interaction (using view data).
The source does not specify implementation details such as data format, frequency of access, scope of queries, or whether data would be anonymized or transformed. These details can significantly affect whether shared data is technically usable for modeling, experimentation, and evaluation.
The technical burden of data sharing—latency, volume, schema stability, and access controls—can determine whether competitors can actually incorporate the data into their systems.
Compliance and competition: what digital rules mean in practice
The European Commission framed the data-access requirement as a way to comply with the bloc’s digital rules. While the source does not enumerate which specific rulebook provisions are being applied, it establishes the regulatory direction: the EU wants access to search data to support competition among search providers.
For the search industry, this matters because competition involves not only crawling and indexing but also the feedback loops that improve ranking. If competitors can obtain signals that reflect how users interact with results, they may be able to iterate on relevance and ranking strategies.
Sharing data that includes query, click, and view signals raises questions about privacy, aggregation, and data minimization. The source does not address these topics directly. Based on the report, the EU’s stated goal is to make the data accessible to rivals under specific conditions.
What to watch next: implementation details and technical impact
The Commission’s statement, as summarized by Tech-Economic Times, specifies the types of data but not the engineering mechanics of sharing. That gap is where the next phase will likely play out: how access is delivered, what controls exist, and how competitors are expected to use the information.
From an industry perspective, key technical questions include:
- How access is provided: whether via APIs, data feeds, or another mechanism (not specified in the source).
- How “terms” are defined: what “fair, reasonable and non-discriminatory” means in measurable terms (not specified in the source).
- How data is scoped: whether access covers the full range of search traffic or only selected segments (not specified in the source).
- How rivals can validate performance: whether the shared ranking, click, and view signals are sufficient to run meaningful experiments (not specified in the source).
The direction is clear: the EU is targeting search-data access as a lever for competition. For developers and researchers in search technology, this could influence how evaluation pipelines are built, particularly the way systems incorporate user interaction signals into ranking and relevance tuning.
