The regulator's move, announced on 3 June 2026, follows Google's designation as having strategic market status (SMS) under the Digital Markets, Competition and Consumers Act 2024, which came into force in January 2025, according to Sky News. Google holds roughly 90% of the UK search market, a dominance that has made it the primary gateway for customer acquisition across media, e-commerce, and services.

For UK SMEs and scale-ups whose growth models depend on organic search visibility, the conduct requirement is not an abstract regulatory event. It could reshape how traffic flows from Google to third-party websites, how content is surfaced, and how the platform monetises the work of publishers and businesses.

What the conduct requirement covers

The CMA's conduct requirement is a set of targeted rules designed to address specific harms the regulator has identified in Google's operation of its search platform. According to Sky News, the rules are intended to secure "a fairer deal for publishers and consumers" while also improving Google's services.

The conduct requirement sits within the SMS framework established by the Digital Markets, Competition and Consumers Act. Under this framework, the CMA can impose obligations on designated firms that go beyond traditional competition enforcement. Rather than punishing past behaviour, the regime is designed to set forward-looking rules governing how dominant platforms interact with the businesses and users that depend on them.

UK publishers have long argued that Google's search snippets and AI-generated summaries reduce click-through traffic to their websites. The News Media Association has estimated that annual losses run into the hundreds of millions of pounds. While the full scope of the conduct requirement has yet to be detailed in a published compliance framework, the CMA's stated objectives suggest it will address how Google displays third-party content in search results and the degree to which users are directed away from original sources.

For businesses outside the publishing sector, the practical question is whether the requirement will alter how Google ranks, displays, and links to commercial websites. Any obligation on Google to increase referral traffic to original content sources, or to limit the extent to which its own products and features occupy prime search real estate, could have material effects on customer-acquisition costs.

Timeline and enforcement teeth

Google has been given nine months to implement the conduct requirement, placing the compliance deadline at approximately March 2027. That window gives the company time to make technical and operational changes to its search platform, but it also gives the CMA time to develop monitoring and enforcement procedures.

The enforcement mechanism is substantial. Non-compliance with a conduct requirement under the Digital Markets, Competition and Consumers Act could expose Google to fines of up to 10% of global turnover, according to the legislation. For a company of Google's parent Alphabet's scale, that figure would run into tens of billions of dollars. The penalty regime is designed to ensure that even the largest technology firms treat CMA requirements as binding obligations rather than advisory guidance.

The nine-month timeline is relatively compressed for a platform of Google Search's complexity. Changes to ranking algorithms, content-display formats, and monetisation structures require extensive testing. Businesses that depend on search traffic should expect a period of adjustment, during which Google may trial different approaches to compliance before settling on a stable configuration.

What changes for UK businesses reliant on search traffic

The most immediate question for UK businesses is whether the conduct requirement will increase the volume and quality of organic referral traffic from Google Search. For many SMEs and scale-ups, Google is not merely one channel among several; it is the dominant source of new customer discovery.

If the CMA's rules require Google to reduce the prominence of its own features, such as AI-generated answer panels, shopping carousels, or knowledge boxes, that could push more clicks toward third-party websites. Publishers, online retailers, and service providers could all benefit from a shift in traffic distribution.

However, the effects may not be uniform. Businesses that have invested heavily in search-engine optimisation to compete within Google's current framework may find that the rules alter the competitive dynamics of search rankings. A conduct requirement that changes how Google displays content could favour some types of businesses over others, depending on the specific obligations imposed.

There is also a timing consideration. The compliance deadline of approximately March 2027 means that any changes to search traffic patterns are unlikely to materialise before the second quarter of that year at the earliest. Businesses planning marketing budgets and customer-acquisition strategies for the next 12 to 18 months should factor in the possibility of a significant shift in organic search dynamics, but should not rely on it.

Practical steps for operators

Finance directors and founders running businesses with significant search-traffic dependence would be well served by auditing their current exposure. Understanding what proportion of revenue is attributable to Google organic search, and how that traffic breaks down by query type, content format, and device, provides a baseline against which future changes can be measured.

Diversification of traffic sources remains prudent regardless of regulatory outcomes. Businesses that have built customer-acquisition models around a single platform carry concentration risk. The CMA's intervention underscores that platform behaviour is subject to change, whether driven by regulation, algorithm updates, or commercial strategy.

How this fits the broader UK digital-regulation agenda

The conduct requirement on Google Search is part of a wider programme of digital-market regulation in the UK. The Digital Markets, Competition and Consumers Act gave the CMA a new set of tools to address the market power of the largest technology platforms, and the Google SMS designation was among the first to be made under the regime.

The CMA has signalled that it intends to use the SMS framework actively. Other large technology firms could face similar designations and conduct requirements in the coming years. For UK businesses, the broader implication is that the regulatory environment around digital platforms is becoming more interventionist, with potential consequences for any company whose operations are intertwined with those platforms.

The UK's approach differs from the European Union's Digital Markets Act in some respects, but shares the underlying objective of constraining the ability of dominant platforms to set the terms of competition. Businesses operating across both jurisdictions may need to navigate parallel but distinct compliance regimes, each with its own timelines and requirements.

For now, the CMA's conduct requirement on Google Search is the most concrete regulatory action affecting UK businesses' relationship with the platform. The nine-month implementation window provides a defined period in which to prepare. What matters most for operators is not the regulatory politics, but whether and how the rules change the flow of traffic and revenue on which their businesses depend.
