There is a new toggle sitting in Google Search Console that lets you pull your site out of AI Overviews and AI Mode while keeping your normal search rankings. It looks like a simple yes or no. It is not, mostly because Google has not yet given anyone the numbers needed to answer it.
Here is what the control actually does, what it quietly takes with it, and why most small businesses arguing about this are arguing about the wrong decision.
What the setting covers
The control lives under Settings in Search Console, labelled Search generative AI. Google is rolling it out to a subset of verified properties, so it may not be in your account yet. Google’s own Search generative AI control documentation is the only source worth trusting on the specifics, because the behaviour has already changed once.
Leave it on the default and your content can appear as links inside AI Overviews, AI Mode, and the generative features in Discover, and it can be used to ground those answers. Switch it to exclude and your site drops out of all of that, links included. Google says it began respecting these changes on 17 June. Processing takes a few days, then content usually falls out within a day or two, though caching can stretch that.
What it does not do matters just as much:
- It is not a ranking signal. Your position in regular search results should not move.
- It does not override Merchant Center or Google Ads. Shopping participation stays a separate decision.
- It does not stop your content being used for AI training. That runs through Google-Extended in robots.txt, which is a different lever entirely.
Those three distinctions catch people out constantly. If your goal is to keep your writing out of model training, this toggle does nothing for you.
The part nobody mentions in the setup guide
Google treats AI features and regular results as separate things. Google’s actual results page does not always agree.
Top Stories carousels have started rendering inside AI Overviews. John Shehata of NewzDash put the rate at roughly 1 in 6 US trending news queries, or 15.5% of tracked results where Top Stories appeared, with the UK figure at 17.46%. His reading is that opting out of AI features will likely pull publishers out of Top Stories when the carousel sits inside an AI Overview.
Two caveats worth holding onto. NewzDash sells news visibility tracking, so it has commercial interest in the finding, and it has not published sample sizes or collection dates. Google has not confirmed how the control handles a traditional feature displayed inside an AI feature. Search Engine Journal covered the full detail of the opt-out trade-offs if you want the longer version.
Still, the principle holds even if the number moves: a property-level switch can remove placements that were never described as AI placements.
You cannot currently measure what you would lose
This is the real problem with the decision.
The generative AI performance report, also rolling out to a subset of accounts, shows impressions from AI features broken down by page, country, device and date. Impressions only. No clicks. No queries. Your analytics can show Google organic referrals, time on site and conversions, but it cannot separate a visit that came from an AI Overview from one that came from a blue link.
So the maths is: unknown traffic value, unknown conversion value, against a change you can reverse but only after several days of processing and caching. The UK’s Competition and Markets Authority has required Google to supply click data and click-through rates, with most of those measures starting in December, and page-level controls by March 2027. Until then you are guessing.
A worked example
Take a six-person accountancy firm in Manchester running a blog on tax deadlines and allowances. Their content is exactly the kind that gets summarised: short factual answers with numbers in them. The partner reads about AI Overviews eating clicks and wants to opt out.
Before touching anything, the useful questions are:
- Does the property even have the control yet? If not, the decision is theoretical.
- What does the generative AI report show in impressions, and how does that compare to total search impressions? If AI features are 3% of impressions, this is not where the business is won or lost.
- What is a blog visit actually worth here? For that firm, a tax-deadline article is not monetised by the pageview. It is monetised when someone reads it, trusts the firm, and calls. Being cited inside an AI answer with a link still supports that. Being absent supports nothing.
That third point is where most of these conversations go wrong.
The uncommon takeaway
The opt-out is a publisher’s tool wearing a webmaster’s clothes.
It makes sense if your revenue comes from impressions on your own pages, because in that model an AI answer that satisfies the user is a direct substitute for your business. That is the situation news publishers are in, and it is why the CMA forced the control into existence.
Most small businesses are not in that model. They sell services, software or products, and their content exists to get them in front of someone who might buy. For those sites, opting out removes a discovery surface and protects nothing measurable. The honest recommendation for the large majority is to leave it alone and spend the same hour on getting cited inside AI answers instead.
What can go wrong
Three things, in rough order of likelihood.
You lose placements you did not know were connected. The Top Stories pattern is the known case. There may be others that nobody has tracked yet, because the boundary between AI surfaces and traditional ones keeps moving.
You cannot prove the decision either way. With impressions-only reporting, you will not be able to show anyone, including yourself, whether opting out helped. That is an uncomfortable position to be in six months later when traffic has drifted for unrelated reasons.
It is all or nothing. The control works at property level. If you have one section of the site where being summarised genuinely costs you and another where visibility helps, you cannot split them until page-level controls arrive in 2027.
This may not be worth thinking about at all if AI features are a small share of your impressions, if you sell something with a considered buying process, or if your property has not received the setting yet.
Editor’s note: This area changes quickly, so check the latest platform policy before making compliance decisions.
What to do this week
Open Search Console and check whether the Search generative AI control and the generative AI performance report exist on your property. If they do, record your current AI impressions figure and today’s date somewhere you will find it again. Then wait. The click data Google has been required to supply starts arriving in December, and that is the first point at which this becomes a decision you can actually make with evidence rather than instinct.
If you find yourself impatient with that answer, ask what you would do differently tomorrow if the numbers came back either way. For most sites, honestly, nothing.
