Google AI Under Investigation: What UK Regulators Mean for the Future of B2B Marketing

The UK’s Competition and Markets Authority (CMA) has launched a formal investigation into Google’s AI-powered search services, marking a critical inflection point in the regulation of generative AI and digital market dominance. At the centre of this inquiry is Google’s AI Overviews—a feature that delivers synthesized answers at the top of search results, often bypassing traditional links to publishers and advertisers.
While the headlines focus on publisher traffic loss and antitrust concerns, the deeper implications for B2B marketers are profound—and urgent.

What’s Changing in Search?

Google’s AI Overviews, powered by its Gemini model, are designed to provide instant, conversational answers to user queries. But this shift toward zero-click search is reshaping how users discover, engage, and convert—especially in complex B2B journeys.

• Visibility is shrinking for organic content, particularly long-form thought leadership and niche solution pages.
• Attribution is opaque, making it harder to track engagement and ROI.
• Content repurposing by AI raises concerns over IP, brand control, and messaging integrity.

Why the CMA Is Investigating

The CMA’s probe—its first under the new Digital Markets, Competition and Consumers Act—will assess whether Google’s practices:

• Stifle competition by self-preferencing its own services.
• Exploit publisher and advertiser content without fair compensation.
• Limit innovation by shaping how AI search interfaces evolve.

If Google is designated with Strategic Market Status (SMS), the CMA could impose conduct requirements, including mandatory attribution, traffic-sharing, and opt-out mechanisms for AI-generated summaries.

What This Means for B2B Marketers

1. Organic Reach Is Under Threat

AI Overviews often surface answers without linking to source content. For B2B marketers relying on SEO to drive awareness and lead generation, this means:

• Lower click-through rates (CTR)—some publishers report drops of up to 56%.
• Reduced visibility for niche or technical content.
• Fewer opportunities to guide users through multi-touch journeys.

Content Strategy Must Evolve

2. Content Strategy Must Evolve

Marketers must rethink how they structure and distribute content:

• Structured data and schema markup become essential for AI discoverability.

• Brand voice and differentiation must be embedded in formats AI can’t easily replicate.

• Owned channels (email, webinars, gated assets) regain importance as search becomes less reliable.

Paid Search ROI May Shift

3. If AI Overviews dominate the top of the SERP, paid ads may see:

• Lower impressions and engagement.
• Increased competition for fewer visible slots.
• Pressure to diversify spend across platforms and formats.
