Should You Opt Out of Google's AI Search Features?

Can You Now Hide Your Site From Google's AI Answers?

As of September 2026, yes. Google Search Console has a setting called the Search generative AI control. Set it to Exclude and your pages stop appearing inside AI Overviews, AI Mode, and generative AI features in Discover. Google rolled it out to every site owner by 31 August 2026.

This is the first time Google has given site owners a clean on and off switch for its AI answers. Before this, the only real lever was blocking Googlebot, which also removed you from normal search results. That was never a trade a serious business would make.

So the question has changed. It used to be whether we could get out of this at all. Now it is whether we should. We work on B2B sites every week where that question is live, and for almost all of them the honest answer is no. Here is the reasoning, and the small number of cases where it flips.

What Is the Search Generative AI Control?

It is a per property setting in Google Search Console, under Settings, then Search generative AI. Google documents three options: Include, which is the default, Exclude, and Inherit from parent. Child properties follow the parent unless you override them. The whole thing is one choice on one screen.

Google says the change is not instant. Its help documentation states that content will be excluded within one to two days after the control goes live, and that some content may take longer because of caching and propagation. This is not a switch you flip during an incident and expect to see results the same hour.

Google also tested it before shipping it widely. The company's announcement post for website owners says the control started with a subset of site owners in the United Kingdom in June 2026, then reached everyone globally by 31 August 2026.

What Does Choosing Exclude Actually Stop?

Two things, according to Google's own help page. Your content stops being shown as a link inside those AI features, and it stops being used to ground the AI response. Grounding is the part where the model pulls facts from your page to build its answer. Both go away together.

That second part matters more than most people notice. You are not just giving up a link in an AI box. You are telling Google not to read your page when it writes the answer your buyer sees. If a competitor stays included, their framing of the topic becomes the answer and yours does not exist.

Google is explicit that the setting covers AI Overviews, AI Mode, and generative AI features in Google Discover. It is one control for all three. You cannot keep AI Overviews and drop AI Mode.

What Does Excluding Your Site Fail to Stop?

More than people expect. Google states that excluding your site does not stop your content being used for overall Search ranking, for language understanding, or for AI model training. The control governs visibility in specific generative AI features. It is not a privacy setting and it is not a training opt out.

Google adds one more clarification that we think is underrated. The control is not used as a ranking or inclusion signal affecting other parts of Search. In plain terms, choosing Exclude should not hurt your normal rankings. It also should not help them.

So the trade is narrow and it runs one way. You lose AI surface. You keep classic search. You do not gain anything back.

How Much Reach Would You Be Turning Down?

A lot, on Google's own numbers. In its post for website owners, Google says AI Overviews has passed 2.5 billion monthly active users and AI Mode has passed one billion monthly users. At Google I/O 2026 the company said AI Mode queries have more than doubled every quarter since launch.

Google is also making these boxes more link friendly, not less. The same announcement describes more inline links inside AI responses and website previews added to encourage clicks. It mentions subscription labels too, and a Preferred Sources feature that lets people pick sites they want to see more of.

That is the shape of the bet. Google is pushing attention through a surface that is growing fast and is being tuned to send more clicks out. Opting out now means opting out of the direction of travel.

There is a second reason to care. Google said at Google I/O 2026 that it is building Search agents, including information agents that run in the background around the clock and watch blogs, news sites and social posts for updates. Those agents launch first for Google AI Pro and Google AI Ultra subscribers. If agents become a real discovery path, an excluded site is invisible to them inside Search.

Is This Control Different From robots.txt and nosnippet?

Yes, and the difference is worth knowing. Google's documentation on AI features says robots.txt directives for Googlebot are the control for managing crawl access, while nosnippet, data-nosnippet, max-snippet and noindex limit what shows from your pages in Search. Those tools are blunt. They affect normal results too.

The new Search Console control is the first one that is surgical. It touches the AI features and leaves the rest of Search alone. If you have been using nosnippet to keep content out of AI boxes, you have been paying a real price in ordinary search snippets for years. You can stop.

Google-Extended is a third thing again. Google's documentation describes it as a control for AI training and grounding in some of Google's other systems, which is separate from these Search AI features. Three controls, three jobs. We covered how they fit together in our guide to controlling AI crawlers with robots.txt, and the new setting does not replace any of it.

How Do You Measure AI Search Before You Decide?

Use the Generative AI performance report in Search Console. Google's help documentation says it shows how many times links to your site were shown to a user in a generative AI feature. You can group the data by pages, countries, dates and devices. It is the only first party view of this surface.

Know its limits before you lean on it. Google's documentation says the report carries impressions only. There are no clicks, no click through rate and no position data. AI Overviews and AI Mode are not broken out separately, so you get one combined number. The report caps at 1,000 rows, and the most recent days are marked as preliminary because they can still change.

That is still enough to make a decision with. If the report shows meaningful impressions on the pages that earn you money, excluding yourself is a straight loss. We walk through reading this data properly in our piece on the Search Console generative AI performance report.

Should a B2B SaaS Site Ever Choose Exclude?

Rarely, but the cases are real. We would only consider it where being quoted by an AI system creates legal, contractual or safety exposure that outweighs demand generation. Think regulated financial guidance, medical information, or content a client is contractually required to keep inside a controlled context. Marketing pages almost never qualify.

The argument we hear most often is about zero click search. The worry is that AI answers take the click and you get nothing back. That worry is fair, but excluding yourself does not return the click. The answer still gets written. It just gets written from someone else's page instead. We set out a better response in our take on building a zero click search strategy.

There is also a scoping option worth knowing about. Because the control works per property, and child properties can inherit or override the parent, a company could exclude a documentation subdomain while leaving the marketing site included. That is a far more sensible use of the switch than an all or nothing call across the whole domain.

Does Google Want You to Build Special Files for AI?

No, and Google now says so directly. Its guide to optimizing for generative AI features states that you do not need to create new machine readable files, AI text files, markup or Markdown, and it names llms.txt as an example. It also says structured data is not required for generative AI search.

The same guide says you do not need to break content into tiny pieces, and you do not need to write in a special way just for generative AI search. Google's stated position is that its AI features run on the core Search ranking and quality systems, so ordinary SEO work still carries the load.

We read that as a useful correction to a noisy year. A lot of advice sold in 2026 assumed AI search needed its own file format and its own house style. For Google specifically, the company says it does not. Other answer engines are not Google and can behave differently, so we still keep schema markup in place for rich results and keep watching the rest.

What Should You Do About This Before the End of 2026?

Three things, in order. Open Search Console and confirm the control is set to Include, because a stray change on a child property is easy to miss. Then pull the Generative AI performance report and record a baseline. Then leave the switch alone unless a legal or contractual reason to move it appears.

The bigger point is that the exit door is now clearly marked, and most companies should walk straight past it. The work itself has not changed. Pages still need to be indexable, fast, clearly organised and genuinely useful, because Google says those are the same systems feeding the AI answers.
