Why Most UK B2B Brands Shouldn’t Take Google’s New AI Opt-Out

The Competition and Markets Authority has handed UK websites the power to block Google from using their content in AI search summaries. For news publishers, it’s a win they’ve been pushing for. For most B2B brands, taking the same opt-out would be self-harm.

On 3 June 2026, the watchdog announced that UK media websites can now block Google’s AI Overviews and AI Mode from using their content, without losing position in regular Google search results. It’s the first time UK websites have been given a granular AI-search opt-out, and it follows the CMA’s earlier decision to designate Google with strategic market status in general search services.

The publishers welcoming the decision have specific reasons for doing so, tied to how their revenue model works. Those reasons don’t apply to most of the businesses commissioning us for SEO services across organic and AI search. Where a publisher loses revenue when a user reads an AI summary instead of visiting their website, a B2B brand loses visibility when its content isn’t summarised at all. The two problems are opposite outcomes of the same Google tool.

The control is currently being tested with a small group of UK media sites. The CMA’s stated intent is to roll it out more widely, and within a year or two it’ll be available to most UK websites. The temptation to use it once it lands is the risk to flag now, because the media coverage is already framing the opt-out as the right move for any website worried about losing control to AI.

What the CMA Ruled

Three obligations sit at the heart of the new requirement, all of them targeting Google’s UK search business and grounded in the watchdog’s strategic market status designation. The first gives website owners control over how their content appears in AI search features without that decision affecting regular Google search rankings, which solves the problem that has held publishers back from blocking AI Overviews until now.

The second requires Google to attribute publisher content with clear links when it appears in AI-generated answers, so users can see where summaries are sourced. The third sets the rollout schedule, with a subset of UK-based media sites getting the control from 3 June 2026 and the stated goal of extending it globally.

Smith, who represents news publishers on Google search issues, described the watchdog’s intervention as a “big win” that will help publishers keep some control over how the US company uses their work. The CMA has signalled that further announcements about Google’s search business will follow in the coming weeks, which means the AI opt-out is the start of a wider regulatory programme rather than a one-off intervention.

Why News Publishers Want This

The publisher case is largely correct on its own terms. Google AI Overviews answer a user’s question directly at the top of the search results page, often by quoting a sentence or two from a publisher’s article. Many users read the summary and never click through to the original journalism, which means a missed page view, a missed ad impression, a missed subscription prompt and a missed retargeting opportunity all in the same moment.

According to the Guardian’s coverage of the ruling, multiple publishers have publicly stated that AI Overviews have meaningfully reduced their click-through traffic and therefore their revenue. The News Media Association, which represents UK news publishers, described the CMA decision as a “significant step towards levelling the playing field and building a fair, transparent digital economy where premium content is properly respected and fairly compensated”.

For a business whose revenue depends on the user landing on its own pages, being summarised away in an AI Overview is a real and measurable loss. The new opt-out gives those publishers a tool to protect against that loss without sacrificing their wider presence in Google search results, which until now was the only way to block AI Overviews entirely.

The B2B Paradox

The same mechanism looks completely different from a B2B perspective. A B2B agency, a SaaS company, a healthcare provider, a manufacturing firm or a professional services brand doesn’t make its money from page views on its website. It makes its money when a buyer reaches the end of a long research process and decides to talk to it.

That research process increasingly starts on ChatGPT, Perplexity, Claude or Google’s own AI Mode. Buyers are typing vendor-discovery queries into these tools and reading the shortlists that come back. The vendor names that appear in those shortlists get the next conversation. The ones that don’t appear get nothing.

The mechanism by which a B2B brand gets named in an AI search response is by having its content used to write the response, either directly through pages on your own website that rank for the underlying topic or indirectly through agency-written ranking content that includes you in its shortlist. Pulling out of that channel removes you from the discovery layer your future buyers are starting to use.

The paradox the celebratory coverage misses is that AI Overviews aren’t a single threat. They’re a different transaction for different business models. The same tool that costs a publisher a click-through earns a B2B brand a place on a buyer’s shortlist. AI search optimisation is now a category in its own right, with its own measurement, tactics and buyer behaviour, and opting out of it is opting out of the layer where B2B buyers are increasingly making vendor decisions.

Who Should Not Opt Out

Most UK B2B brands fall into one of the categories below, where opting out would remove them from a discovery channel they need to be in. The page-view loss from being summarised in an AI Overview is real but small. The shortlist absence is fatal.

• Service businesses including agencies, consultancies, software vendors, healthcare providers, accountants, solicitors and recruiters, whose buyers conduct multi-week research before buying.
• B2B SaaS and product companies whose buyers ask AI tools for category comparisons before visiting any vendor website.
• Sector specialists, such as the WCAG 2.2 specialist working with NHS Trusts or the WordPress agency for higher education, whose niche specialism is exactly the content AI search wants to cite.
• Local and regional service providers whose buyers ask AI tools for area-specific shortlists, where being in the answer matters more than the small click-through traffic loss.

The reasoning is the same across these examples. A B2B buyer using AI search is at the top of the funnel and is using the tool to build a shortlist, not to read your article. Being in the shortlist is the win, and the visit to your website that follows is the conversion stage where the AI Overview snippet has already done its job. Sector-specialist positioning, such as our work as an NHS marketing agency, is exactly the kind of content AI search rewards because it answers the specific niche query the buyer typed.

When Opting Out Does Make Sense

The opt-out is the right move for some businesses, where the revenue model depends directly on the user landing on the website rather than reading a summary somewhere else. These cases are real, and they don’t describe most of the UK B2B audience.

• News and editorial publishers whose revenue is tied to page views, ad impressions and subscription conversions.
• Paywalled and subscription-content businesses where free AI summaries reduce the conversion to paid access.
• Highly regulated or confidential content businesses where summaries by an AI model risk inaccuracy or compliance damage, including medical journals, legal commentary and regulated financial information.
• Data-licensing businesses where the value of the data sits in the access itself, not in awareness.

Almost nothing on that list applies to a typical UK B2B marketing-services audience. The list describes the publishing industry the CMA was responding to, which is why the opt-out has rolled out to UK media sites first and why the framing in the press coverage has come from a publisher perspective. Read the coverage as relevant to the publishing industry rather than as guidance for your business.

What B2B Brands Should Do Instead

The right answer for B2B brands isn’t to retreat from AI search. It’s to invest in being the source AI search wants to cite. That means publishing original methodology, primary research, named-author commentary and niche-specialism content that no one else can produce.

Being included in the agency listicles that already exist is the single highest-impact move. Vendor-recommendation queries across the major AI search tools lean heavily on agency-written ranking articles about UK B2B agencies, picking up shortlists from “top UK B2B agency” content already published by other agencies. Direct outreach to the authors of those listicles, with a short pitch on why your brand fits their next update, is a low-effort tactic with measurable return.

Structured data is the third lever. Adding schema.org markup for your services, your organisation and your people, with sameAs references to LinkedIn and Wikidata profiles, makes your brand a clearer entity for AI to recognise. The relationship between structured data and AI search citation isn’t perfect, but it’s measurable, and the cost of adding the markup is low.

Specialism content is the fourth lever. Pages that document an audit process, a methodology or a regulatory interpretation in a specific sector, such as the depth of website accessibility work needed for NHS Trusts or higher-education websites, get cited because no generalist agency website has the same depth on that topic. Picking a niche and committing to it deeply enough to publish original work is how you become the source AI shortlist queries reach for.

Press coverage and entity associations sit alongside this work. Independent press coverage that names your brand and connects it to its specialism is the strongest entity signal for AI search, and over months it contributes to long-term AI search visibility in a way that LinkedIn posts can’t match. Pitching trade publications, sector journals and analyst newsletters with the same primary research you publish on your own website is how that signal compounds over time.

The Bigger Picture

The CMA’s ruling is a watershed in how regulators treat AI search. It’s the first time a Western regulator has forced a major AI search provider to give third-party websites granular control over how their content is used in AI products. The same pattern will play out across other regulators over the next two years, with Google, Microsoft, OpenAI and Anthropic likely required to provide equivalent controls in the UK, the EU and possibly the US.

That isn’t a reason to use the control as soon as it lands. It’s a reason to think carefully about what you want from AI search before the option is in front of you. For news publishers, the answer is less of it on their terms. For B2B brands, the answer is more of it with their name in the picture.

The opt-out will work its way out of media trials and across the wider UK web within the next 12 to 24 months. When it reaches your website, the decision shouldn’t be a reflex based on the publisher framing in the media coverage. It should be a clear-eyed read of your revenue model, your buyers’ research behaviour and the visibility you stand to lose by stepping out of the channel they’re now using.

For most of the UK B2B brands we work with, that means staying in. The alternative is voluntarily removing your name from the shortlists your future customers are starting to ask AI to compile for them, just as that mechanism is becoming the way they find vendors at the top of the funnel.
