The UK Just Forced Google to Give You an AI Search Off-Switch

The UK's competition regulator just did something no other country has managed.

On 3 June, the Competition and Markets Authority used the Digital Markets, Competition and Consumers Act to impose its first binding conduct requirement on Google. The result: a new toggle in Search Console that lets website owners opt out of having their pages appear in AI Overviews, AI Mode, and AI-generated features in Discover.

UK site owners are getting it first. If you manage a website through Search Console, you may already have it.

We have written about AI search several times this year. Each time, the advice has been the same: adapt to it, because it is not going away. Now Google has given you the option to walk away from it entirely.

The question is whether you should.

What the toggle actually does#

The new control is straightforward. Switch it on and your website stops appearing inside AI-generated features on Google. That means AI Overviews (the summaries at the top of search results), AI Mode (Google's conversational search), and any AI-generated content in Discover.

Your regular search rankings are unaffected. Google has confirmed this explicitly: opting out will not change where you appear in traditional search results. You still show up in the normal list of links. You just disappear from the AI layer on top.

The toggle became active on 17 June for the initial UK rollout. The full legal requirement comes into force on 3 December 2026, by which point every UK site owner should have access.

What you can now see#

Alongside the toggle, Google added dedicated AI performance reports to Search Console. For the first time, you can see how often your pages appear inside AI-generated features.

The reports break down impressions by page, country, device, and date. You can see which of your pages AI is pulling from, and how frequently.

There is a limitation: click data is not included yet. You can see how often your content appears in AI answers but not how often people click through from them. Google says click-through data is coming, but has not given a date.

Even impressions alone tell you something useful. If your pages are showing up in AI features, it means Google's systems consider your content worth citing. If they are not, that is worth knowing too.

Why the CMA did this#

This is not generosity from Google. It is a regulatory order.

The CMA has been watching AI search erode the traffic that websites depend on. AI Overviews now appear on roughly half of all Google searches. When they do, click-through rates to the underlying websites drop significantly. Publishers and businesses that depend on organic search traffic have been losing visibility with no data about the problem and no way to control it.

The Digital Markets, Competition and Consumers Act gave the CMA new powers to intervene. This is the first time those powers have been used. Google is now required to give UK website owners both the data (through the reports) and the control (through the toggle) to make an informed choice about whether their content appears in AI features.

No other country has done this yet.

Why most small businesses should leave it on#

This is where it gets counterintuitive.

If you run a local service business, a trades company, a professional services firm, or any small business that relies on people finding you through Google, opting out of AI search is almost certainly the wrong move.

AI Overviews and AI Mode are not going away. They are growing. The share of searches that trigger AI-generated content has roughly doubled in the past year. Removing yourself from that layer means disappearing from the fastest-growing part of how people discover local businesses.

The data supports this. Research from earlier this year found that businesses cited in AI Overviews see significantly more clicks per impression than those that are not cited. Being mentioned in an AI answer does not replace the click to your website. It primes it. Someone reads about your business in a summary, then clicks through to check you out properly.

We wrote about this shift in May: Google's AI search is starting to send clicks back. The changes Google made to link placement inside AI results mean that being cited there is increasingly valuable.

For most small businesses, the right response to this toggle is the same as it has been all year: make sure your website has clear, specific content that AI wants to cite. Do not hide from the system. Be the answer it reaches for.

When opting out might make sense#

There are genuine cases where the toggle is worth considering.

If you are a publisher whose full articles are being summarised in AI Overviews, leaving readers with no reason to visit your site. If you have clear, measurable evidence that AI features are cannibalising your traffic rather than driving it. If your business model depends entirely on people reading your content on your site, not getting the gist from a summary.

Most small businesses do not fit any of those categories. A plumber, a solicitor, a restaurant, a design studio - these businesses benefit from being mentioned in AI answers. The summary drives the enquiry, not replaces it.

But if you do fit one of those categories, the toggle is there. And the new AI performance reports will help you make the decision with actual data rather than guesswork.

What to do right now#

Log into Google Search Console. Check whether you have the new AI performance reports under the "Search results" section.

If you do, look at the data. See which of your pages are appearing in AI features and how often. High impressions is good news. It means Google considers your content worth citing. Low or zero impressions means your content is not being picked up by AI, which is a signal to work on the clarity and specificity of your pages, not a reason to opt out.

If you do not have the reports yet, you will soon. The rollout is UK-first and still expanding.

And leave the toggle alone. For most small businesses, being visible in AI search is where the growth is. Opting out now would be like removing yourself from Google Maps in 2015 because you were not sure about digital.

We have covered what makes content work for AI search, how local search is changing, and how Google's AI is starting to send traffic back to websites. If you are catching up on this series, those are good places to start.

The CMA gave you a choice. For most of you, the right choice is to stay visible.
