The UK's new digital-markets regime has moved from designation into concrete obligations for Google Search. The Competition and Markets Authority has imposed conduct requirements covering publisher treatment, fair ranking and data portability after designating Google with strategic market status in general search and search advertising.

For businesses, the practical significance is that concerns about how Google ranks services, uses publisher content and makes search data portable now sit inside a formal conduct framework rather than only general competition law.

Fair ranking creates an explicit standard

The fair-ranking requirement is designed to make Google's approach to ranking search results fair and transparent for businesses. The CMA has also said the framework extends to AI-driven search experiences, which matters as AI Overviews and AI Mode occupy more of the search journey.

That does not mean every ranking decline becomes a regulatory breach. Search ranking remains complex and dynamic. The important change is the existence of a defined conduct obligation and a process through which the CMA can examine compliance.

Publisher controls address AI use and attribution

The publisher conduct requirement is particularly relevant to news and information businesses. The CMA's policy materials describe greater choice and transparency over how publisher content is used in Google's AI features and outside Search for model training, alongside requirements around attribution.

For publishers, that makes content-control settings and traffic economics part of competition regulation as well as SEO. The commercial question is no longer only whether content ranks, but under what conditions it is reused inside search experiences that may reduce the need for a click.

Data portability matters beyond publishers

The separate data-portability requirement is intended to make search data more usable by people and businesses. This could affect the competitive environment for tools and services that depend on access to search-related information.

The CMA's Google Search case remains open, so further measures can follow. Businesses should therefore track the imposed requirements separately from proposals and future interventions, rather than treating the entire digital-markets roadmap as already complete.
