Google AI Overviews Opt-Out: Should You Switch It Off?

Google's AI is stealing your customers, and the new switch in Search Console finally lets you take them back. Since the end of August that line has been doing the rounds in marketing newsletters, trade forums and the comment threads under every SEO post going. It sounds like common sense. For nearly every business that sells something other than information, it is the wrong conclusion.

The switch is real. What it does is narrower than people assume, and what it costs is bigger. So before anyone touches it, I want to take the claim apart one piece at a time.

What Google Actually Built, and Why It Exists

On 31 August 2026 Google finished rolling out what it calls the Search generative AI control to every website in the world. It lives in Search Console under Settings, and it has two positions that matter. Include, the default, lets your pages appear in AI Overviews, AI Mode and the AI features in Google Discover, and lets Google use them to ground the answers it writes. Exclude takes them out of all three.

Google did not volunteer this. Writing on the company blog in June, Mrinalini Loew, who leads Google's Search ecosystem team, said Google was "engaging with regulators like the UK's Competition and Markets Authority" while it tested the control. The same day, 3 June 2026, the Competition and Markets Authority announced a publisher conduct requirement obliging Google to give publishers "effective tools to prevent their content being used to power AI features in search". London forced the issue. Everyone else, Ireland included, got the switch as a by-product.

That origin tells you who it was designed for. Newspapers. Magazines. Recipe sites. Businesses whose product is the article itself. My colleague Eamon has already made the case that a business website is not a publisher, and the same logic holds here. A heating engineer's guide to bleeding radiators is not what they sell. The call-out afterwards is.

None of this is a distant American experiment, either. TechCentral reported Google rolling out AI Mode in Ireland in October 2025, a year ago this month. The people searching for your services are already reading AI answers, whether you have looked at one yourself or not.

Myth One: Switching It Off Brings the Clicks Back

The fear underneath the switch is grounded in real data, and I am not going to wave it away. Pew Research Center tracked the browsing of 900 American adults through March 2025. People who saw an AI summary clicked an ordinary search result in roughly 8% of visits, against about 15% when no summary appeared. Links inside the summary itself were clicked in around 1% of visits. That is a US sample from a single month, and behaviour here may differ in either direction. The direction of travel is still hard to argue with. AI answers mean fewer clicks.

Now take the logic one step further. Opting out does not remove the AI Overview. It removes you from it.

Google's own help page on the control is blunt on the point. Other sites' content still appears in those features, and once you exclude, you "won't receive any traffic or impressions from these features." The answer still sits at the top of the page. It is simply assembled from somebody else's website.

Consider a scenario I expect to see play out more and more. A septic tank servicing contractor in Roscommon has spent years writing clear pages on desludging, inspections and what to do when a tank backs up. The owner reads that Google's AI is eating their traffic and switches the setting to Exclude. A few weeks later a homeowner in the county, with a house viewing booked for Saturday and a tank that has started to smell, asks Google how often a tank needs emptying. The AI Overview still appears. It is now built from a competitor's page and a national directory listing, and the competitor is the cited link. The homeowner rings the business named on screen. Our contractor never knows the search happened.

That is the actual trade on offer. Not "the AI answer or my link". It is "an AI answer that cites me, or one that cites my competitor".

Google also states that the control "isn't used as a ranking or inclusion signal affecting other parts of Search". So your ordinary blue link stays exactly where it was. It just sits beneath an AI answer that now credits a rival, and that blue link was already the thing losing clicks. Opting out fixes none of it.

Opting out changes which sources feed the AI answer. The answer itself stays on the page.

Myth Two: Opting Out Keeps Your Content Away From AI

This is the misreading I see most often, and Google answers it in a single line of that help page: "This control doesn't affect AI training."

The switch governs whether your pages appear in, and ground, three specific Google Search features. Nothing more. Whether Google's models learn from your text is a separate setting called Google-Extended, a robots.txt instruction which, according to Google's crawler documentation, controls whether your content may be used for training future Gemini models. The same documentation states that Google-Extended "does not impact a site's inclusion in Google Search nor is it used as a ranking signal".

Then there is everybody who is not Google. The Search Console switch has no effect whatsoever on ChatGPT, Perplexity or Microsoft's Copilot. Those companies run their own crawlers under their own rules, and Search Console has no say over any of them.

So add it up. An owner who flips the switch to protect their writing from AI has removed themselves from Google's AI answers, left Google's model training exactly as it was, and done nothing about any other AI company. Plenty of cost. Very little protection.

If you genuinely want a page out of Google altogether, Google's advice is a noindex tag. That takes it out of ordinary results as well. For a business that depends on being found, that is rarely what anyone actually wants.

Myth Three: You Have to Decide Today

There is a faint whiff of urgency around this, as if leaving the default alone is a choice you will come to regret. It is not a one-way door. Google says you can change the setting, or set it back to inheriting from a parent property, at any time, and that a change generally takes a few days to apply. So the sensible approach is to measure before you touch anything.

Search Console now includes a generative AI performance report as an expandable tab under the main Performance report. As Search Engine Roundtable's Barry Schwartz noted when it went global, it shows impressions in AI features by page, country, device and date. It shows no clicks and no queries. You can see that a page appeared in an AI answer, but not what the person asked or whether they came through to your site. Treat it as a signal, not an audit.

Five Checks Before You Touch the Switch

Verify who controls the property. If a former web designer or agency set up Search Console for you, they may still hold owner access, and whoever controls the property controls this switch.
Measure before you change anything. Open the generative AI report and note which pages turn up in AI features and how often; service pages and FAQ pages appearing there are good news, not a threat.
Check for duplicate properties. Where you have both a domain property and a URL-prefix property, the child inherits the parent's setting unless someone has overridden it, so confirm both say what you think they say.
Decide on your own numbers. For most businesses that sell a service or a product, Include remains the right setting.
Review it each quarter. Google says the list of features the control covers may change over time, so put a reminder in the diary rather than reacting to every headline.

When Excluding Your Site Is the Right Call

I would be overselling if I claimed nobody should use this. There is a clear group for whom Exclude makes sense: businesses whose writing is the thing they sell. A training provider whose detailed exam guides are the paid product. The subscription newsletter. Specialist publishers living on page views and advertising. For them, an AI summary of the guide is the product handed out for free, and the regulator's reasoning applies to them directly. If that describes your business, measure first, then exclude without any guilt.

There is a limitation on the other side too, and I would rather say it plainly. Leaving the switch on Include does not guarantee you will be cited. Google chooses its sources, and a thin page on a slow site will lose out to a clear page on a fast one. AI answers also get things wrong. They can repeat an old price, or opening hours you changed in the spring, because that is what an outdated page still says. Include is permission, not a promise.

Make Your Pages the Ones Worth Quoting

If the AI answer appears either way, the useful question is what makes a page the one it draws on. Strip out the agency jargon and the criteria are fairly plain.

Answer real questions in plain words. The question customers ask you on the phone, written down with a straight answer on a page of its own.
Keep facts current. Prices, hours, service areas. An AI answer built from your stale page is arguably worse than no answer at all.
Load fast on a phone. Whoever taps your link inside an AI answer is usually on mobile data, standing in a kitchen or a car park. If the page stalls, the citation was wasted.
Stay in your own hands. If every edit means emailing a developer and waiting a week, your pages fall behind the competitor who fixes theirs in five minutes.

Those criteria are the argument for owning your own WordPress site rather than renting a page on somebody else's platform. W3Techs puts WordPress on roughly four in ten of all websites, and it gives you full control of every page, every heading and every fact on it. I set out the infrastructure side of that in what every business owner needs to know about AI-powered WordPress, and nothing in this new switch changes the argument.

The page that gets quoted is the one that answers the question clearly and loads quickly.

Web60 is built around exactly that. You start by describing your business and letting AI build the WordPress site around that description, so the pages say what you would say. You can edit any of them yourself from the first day, which turns a price change into a two-minute job rather than a change request. Underneath sits Nginx, Redis object caching and FastCGI page caching on Irish infrastructure. In practice, the person who taps your link inside an AI answer sees your page appear quickly, rather than giving up and tapping the next source. The built-in privacy-first analytics need no cookie consent, so those visits are counted even when the visitor ignores a cookie banner. All of it is included in €60 a year.

The Switch Is a Business Decision, Not a Protest

AI answers are on Irish results pages now, and they will not disappear because one website opts out. The Search Console switch does one thing. It decides whether your site is among the sources those answers draw on. For a business that sells information, Exclude can protect the product. Where the business sells a repair, a meal, a service or a physical product, Include usually keeps you in the conversation your customers are already having with Google. Look at the report, find out who holds the keys to your Search Console, and make the call on your own numbers.

Frequently Asked Questions

How do I opt out of Google AI Overviews?

In Google Search Console, open Settings, choose Search generative AI and select Exclude for your property. You need a verified Search Console property for your website to see the setting. Google says a change generally takes a few days to apply, and it covers AI Overviews, AI Mode and the AI features in Google Discover together rather than one at a time.

Will opting out of AI Overviews hurt my Google rankings?

Google says the control is not used as a ranking or inclusion signal for other parts of Search, so your ordinary listings should stay where they are. What you lose is every impression and visit that would have come through AI Overviews, AI Mode and the AI features in Discover, while competitors who stay in can still be cited there.

Does opting out stop Google training its AI on my website?

No. Google's help page states that the control does not affect AI training. Training for Gemini models is governed separately by Google-Extended, a robots.txt instruction, and Google says Google-Extended does not affect your inclusion or ranking in Google Search.

Does the Search Console setting block ChatGPT and other AI assistants?

No. It only applies to Google's own AI Overviews, AI Mode and Discover features. ChatGPT, Perplexity, Copilot and other assistants use their own crawlers and their own rules, and Search Console has no control over them.

Can I change my mind after opting out?

Yes. Google says you can switch the setting back, or return it to inheriting from a parent property, at any time. Expect a few days before the change takes effect, and possibly longer for some content because of caching.

Is Google AI Mode available in Ireland?

Yes. Google began rolling out AI Mode in Ireland in October 2025, as TechCentral reported at the time. It appears as a tab on the results page and in the Google app, alongside the AI Overviews that already sit above ordinary results for many searches.
