Short answer
Most sites should stay in. Search Console now has a toggle that removes your content from AI Overviews, AI Mode and Discover AI without affecting organic rankings. Opting out gives up a growing discovery surface in exchange for nothing measurable, because the report shows impressions but not clicks.
This decision arrived suddenly and most teams are making it on instinct.
The toggle exists because the UK competition regulator required it, not because Google offered it. That origin explains a lot about how narrow it is.
Three controls, three different jobs
These get conflated constantly, and two of them cause damage you did not intend.
| Control | What it actually does | Side effect |
|---|---|---|
| Search Console toggle | Removes you from AI Overviews, AI Mode, Discover AI | None on organic rankings |
| Google-Extended | Blocks AI model training | Does not stop AI Overviews at all |
| nosnippet / max-snippet | Blocks AI features | Also strips your organic snippet |
Row two is the most common mistake. Teams block Google-Extended believing they have opted out of AI Overviews. They have not. AI features draw on the regular index through Googlebot.
Row three is the most damaging. Using snippet directives to stay out of AI answers removes your preview text from ordinary results too. You go partly dark in classic search as the price.
What the toggle does and does not cover
It sits under Settings, then Search generative AI. The default for every property is Include.
- Covers: AI Overviews, AI Mode, AI Overviews in Discover.
- Does not cover: the Gemini app, or ChatGPT, Perplexity, Copilot and Claude. Those are separate systems entirely.
- Google states it is not a ranking signal. Indexing, crawling and ranking are untouched.
- Changes propagate within about a day or two.
Why most sites should stay in
Because you cannot yet measure what you would be giving up.
The Generative AI report shows impressions only. No clicks, no CTR, no queries. So there is no number that tells you whether AI exposure earns you anything or costs you anything.
Opting out on that basis is a guess dressed as a decision. And it is a guess in one direction only: you keep the loss, you never learn the value.
There is a second reason. AI surfaces keep absorbing features that used to stand alone. Opting out today may remove you from things that were not AI features when you decided.
When opting out is defensible
Narrow cases, and all of them are about something other than traffic.
- Your content is the product. Paywalled research, licensed data, subscription journalism. Summarisation substitutes for the purchase.
- Accuracy carries liability. Medical, legal or financial guidance where a partial quote could cause harm.
- A licensing position. Some publishers are negotiating, and participation weakens that.
- You have measured it. If you can show AI impressions are cannibalising clicks on your own data, that is an argument rather than a feeling.
Notice what is not on that list: being annoyed about AI, or losing traffic you have not attributed.
Do this before you touch the toggle
- Look at the Generative AI report. How much exposure do you actually have? Many sites have very little.
- Compare against organic. Did clicks fall when AI impressions rose, on the same pages?
- Check which pages appear. Informational pages appearing is different from your commercial pages appearing.
- Wait for a real baseline. Data only starts from mid-2026. A few weeks is not evidence.
Reading that report properly, including what it hides, is covered in generative AI impressions dropped in Search Console.
The decision is reversible, the data is not
You can switch back, and it takes effect in a day or two.
But the period you spend opted out produces no AI impression data at all, so you lose the ability to compare later. In a surface this new, that history is worth more than most teams realise.
My position, stated plainly: stay in, measure for two or three quarters, and revisit when clicks appear in the report. Regulators have pushed for click data and page-level controls, so the decision you are making today is not the decision you will face next year.
If your traffic already fell
Opting out does not recover it. That is worth saying because the toggle is being reached for as a remedy.
- Positions held, clicks fell? That is displacement. See traffic dropped but rankings the same, where AI is one of eight causes.
- Positions fell too? That is a demotion and has nothing to do with AI features. Start from the four causes triage.
Removing yourself from AI answers does not return the clicks those answers absorbed. It only removes the impressions you were getting alongside them.
Considering opting out because traffic fell?
It is worth confirming AI features are actually the cause first, because in most cases they are not and the toggle changes nothing. Send your Search Console access and within 48 hours I will tell you what is really responsible.
