What the CMA Proposed on January 28, 2026
On January 28, 2026, the UK Competition and Markets Authority published a set of proposed requirements targeting Google's AI Overviews feature. The central mandate: Google must provide publishers with a mechanism to opt their content out of AI Overview scraping and synthesis without any corresponding loss of visibility in traditional organic search results.
This proposal addresses a tension that has been building since Google launched AI Overviews (formerly Search Generative Experience) broadly in 2024. Publishers have argued that Google uses their content to generate AI summaries that reduce the need for users to click through to source websites, effectively extracting value without adequate compensation or consent. The current technical options -- such as blocking Googlebot entirely or using noindex directives -- force publishers into an all-or-nothing choice: allow AI scraping or disappear from search results altogether.
- Granular opt-out: Publishers must be able to block AI Overview usage specifically, without affecting organic search indexing
- No ranking penalty: Opting out of AI Overviews cannot result in lower rankings or reduced visibility in standard search results
- Transparency requirements: Google must clearly communicate how publisher content is used within AI features
- Consultation period: Open for public comment until February 25, 2026 before finalizing requirements
The CMA's intervention stems from its broader investigation into foundational AI models and their competitive effects on downstream markets. The authority has been examining whether Google's integration of generative AI into search creates unfair competitive advantages, particularly by leveraging publisher content without meaningful consent mechanisms.

Google's Response: "Exploring Updates"
Google's public response to the CMA proposal has been notably measured. Rather than contesting the regulatory premise, Google stated it is "exploring updates" to its existing crawling and indexing controls. This language suggests the company recognizes the political and regulatory reality and is positioning itself as a cooperative participant rather than an adversary.
- Willingness to engage with regulatory framework
- Acknowledgment that publishers need more granular controls
- No legal challenge to the CMA's jurisdiction
- Scope and timeline of technical implementation
- Whether opt-out applies to AI training data as well
- How "no ranking penalty" would be verified
The practical challenge for Google is significant. Current crawl control mechanisms like robots.txt and meta robots tags were not designed with granular AI feature controls in mind. Creating a system where content can be indexed for organic search but excluded from AI synthesis requires new technical infrastructure -- potentially a new directive, an extension to existing protocols, or a publisher-facing dashboard for managing AI permissions.
Why This Matters for SEO Strategy
This regulatory development has the potential to fundamentally alter SEO strategy in 2026 and beyond. The current AI search landscape assumes that all indexed content is available for AI synthesis. If publishers gain the right to withdraw that assumption, the entire calculus of generative engine optimization (GEO) changes.
Scenario 1: Major Publishers Opt Out
If large news organizations and authoritative publishers withdraw from AI Overviews, Google's AI summaries lose their most credible sources. AI Overview quality degrades, users trust them less, and organic clicks may partially recover. SEO value shifts back toward traditional ranking factors.
Scenario 2: Strategic Selective Opt-Outs
Publishers opt out only for content where AI Overviews cannibalize traffic but maintain participation for queries where citation drives brand visibility. This creates a more complex, fragmented AI Overview landscape that rewards strategic SEO thinking.
Scenario 3: Few Publishers Opt Out
If most publishers stay in (for fear of competitive disadvantage), the regulatory change has minimal practical effect. However, having the option still establishes an important precedent for content licensing negotiations.
The relationship between AI Overviews and organic traffic is already complex. Research suggests that queries triggering AI Overviews can see reduced click-through rates for traditional organic results, a dynamic we explore in depth in our zero-click search strategy guide. The opt-out mechanism could either accelerate or partially reverse this trend, depending on publisher adoption rates.
Opt-out rights create leverage for publishers to negotiate licensing agreements with Google and other AI platforms, potentially establishing new revenue streams.
Publishers who remain in AI Overviews gain proportionally more visibility as competitors opt out, creating a game-theory dynamic that will shape adoption patterns.
Businesses may need separate content strategies for AI-visible and AI-excluded content, adding complexity to editorial planning and SEO workflows.
How Publisher Opt-Out Mechanics Could Work
While the specific technical implementation is still under discussion, there are several plausible approaches that could satisfy the CMA's requirements. Each carries different implications for how SEO professionals would manage AI visibility.
A new meta tag such as noai or noaioverviews could allow page-level control. This aligns with existing crawl control patterns and would be familiar to SEO professionals.
Implications for SEO:
- Page-level granularity enables selective opt-out strategies
- Straightforward implementation via CMS or tag managers
- Easy to audit and verify compliance at scale
An extension to the robots.txt protocol could define AI-specific user agents or directives, allowing site-wide or directory-level controls. This would follow the precedent set by directives like Google-Extended that Google introduced in 2023 for Bard training data.
Implications for SEO:
- Site-wide or section-level control through a single file
- Requires clear distinction between AI training and AI features
- Precedent exists with Google-Extended user agent
Google could build AI Overview permissions directly into Google Search Console, giving site owners a visual interface for managing AI feature participation without touching code or server configuration files.
Implications for SEO:
- Most accessible option for non-technical publishers
- Centralized management with reporting and analytics
- May not offer the same granularity as code-level solutions
Strategic Implications for Businesses
Whether you are a publisher, an e-commerce brand, or a service business, this regulatory development requires strategic consideration. The opt-out right creates new variables in the SEO equation that were not present before.
- Audit which pages generate AI Overview citations and whether those citations drive meaningful traffic
- Calculate revenue impact of AI-driven traffic loss versus brand visibility gains
- Consider licensing conversations with Google as a potential revenue channel
- Develop content that provides value beyond what AI can summarize
- AI Overview citations can be valuable brand signals -- weigh opt-out carefully
- Monitor competitor opt-out decisions for strategic advantage opportunities
- Strengthen traditional SEO fundamentals as a hedge against uncertainty
- Build direct audience channels (email, communities) that do not depend on search
The opt-out decision is not binary. Businesses may benefit from a page-by-page approach: keeping high-value citation pages in AI Overviews while opting out for content where AI synthesis primarily cannibalizes traffic without providing proportional brand value. This nuanced strategy requires robust analytics and clear understanding of how each piece of content performs across AI and traditional search channels.
How to Prepare Now
Regardless of the final outcome of the CMA consultation, forward-thinking SEO teams should be taking concrete steps now. Preparation reduces risk and positions your business to act quickly once the regulatory framework is finalized.
Audit Your AI Overview Exposure
Identify which of your pages currently appear in AI Overview citations. Use tools like Semrush, Ahrefs, or manual SERP reviews to map out your AI visibility footprint. Document which queries trigger AI Overviews for your target keywords and whether your content is being cited.
Quantify the Traffic Impact
Compare organic traffic trends for pages where AI Overviews appear versus pages where they do not. This data will inform whether opting out is advantageous for specific content categories. Look at both click-through rates and conversion metrics, not just impressions.
Develop a Content Licensing Position
Establish your organization's stance on AI content usage. Whether you plan to negotiate licensing deals, fully participate in AI features, or selectively opt out, having a clear policy ready will accelerate decision-making when opt-out mechanisms become available.
Consider Submitting a Consultation Response
If you are a publisher or business with significant search traffic in the UK market, consider filing a formal response to the CMA consultation before the February 25 deadline. Your input can help shape a regulatory framework that balances publisher rights with the benefits of AI-enhanced search.

Global Regulatory Context and Precedent
The UK CMA's proposal does not exist in isolation. It sits within a broader global movement to regulate how AI systems use copyrighted content and how dominant platforms like Google exercise market power in the AI era.
The EU AI Act, which began phased implementation in 2025, establishes transparency requirements for AI systems, including disclosure of training data sources. While it does not specifically mandate opt-out from AI search features, it creates the legal infrastructure for similar interventions.
Australia's News Media Bargaining Code and Canada's Online News Act established precedents for requiring platforms to compensate publishers. The CMA proposal extends this principle to AI content usage, potentially creating a template other jurisdictions will follow.
For SEO professionals operating across multiple markets, the key risk is regulatory fragmentation. If different jurisdictions adopt different opt-out standards, managing AI visibility could become significantly more complex. A publisher might opt out in the UK but remain visible in AI Overviews in the US, creating inconsistent content strategies and analytics challenges.
- CMA final decision: Expected within weeks after the February 25 consultation deadline closes
- Google's technical response: What specific mechanisms Google implements and how quickly they roll out
- Publisher adoption rates: How many major publishers actually use opt-out controls once available
- EU follow-through: Whether the European Commission pursues a similar requirement under the Digital Markets Act or AI Act
