Google's opt-out switch for AI Overviews is rolling out. What it covers, what it doesn't, and the three levers people keep confusing
Google's Search Console now carries a Search generative AI control — one property-level switch that excludes your site from AI Overviews, AI Mode and the generative AI features in Discover, documented in Search Console Help. Google's page says it is “rolling out to a subset of website owners”, and Search Engine Journal wrote it up on 2026-08-01. It is the delivery of what Google described on 2026-01-28 as exploring controls that “need to avoid breaking Search.” The important part is the scope, because there are now three separate levers that all sound like “opt out of AI”, and they do three different things. We read all three from Google's own docs, then measured how much of your AI exposure the whole set leaves untouched.
Primary source: Google Search Console Help — “Search generative AI control”
What the new control is
It lives at Settings → Search generative AI in Search Console (direct link: `search.google.com/search-console/settings/search-gen-ai`). Two options, property-level, all-or-nothing. Include — the default for every property — means your content “can appear in Search generative AI features” and can earn impressions and clicks from them. Exclude means your content is “prevented from being visible to users” in those features, including being linked to inside them and being used to ground the answer.
Three details from the documentation matter more than the headline. The covered surfaces are named: AI Overviews, AI Mode, and generative AI features in Google Discover. The timing is stated: content is excluded “within 1-2 days after the control goes live, but some content may take longer to be excluded due to caching.” And the carve-outs are explicit: the control “isn't used as a ranking or inclusion signal affecting other parts of Search,” and it “doesn't affect AI training” — for that, Google points you at Google-Extended.
The three levers, from Google's own documentation
| Lever | What it controls | What it explicitly does NOT do |
|---|---|---|
| Search generative AI control (Search Console setting) | Appearance in AI Overviews, AI Mode, Discover's AI features. Property-level, on/off. | Not a ranking or inclusion signal for the rest of Search. Does not affect training. Does not affect Merchant Center or Ads. |
| `nosnippet` / `max-snippet` (robots meta tag) | Per-page. Google's robots meta docs say it applies to “web search, Google Images, Discover, AI Overviews, AI Mode” and “will also prevent the content from being used as a direct input for AI Overviews and AI Mode.” | Also kills your ordinary search snippet — you cannot use it to leave AI while keeping the blue-link preview. Does not apply “where a publisher has separately granted permission for use of content.” |
| `Google-Extended` (robots.txt token) | Whether crawled content “may be used for training future generations of Gemini models” and for grounding in Gemini apps and Vertex AI. | “Google-Extended does not impact a site's inclusion in Google Search nor is it used as a ranking signal in Google Search.” It does not remove you from AI Overviews or AI Mode. |
That third row is the one that has been costing people time for two years. Adding `Google-Extended` to robots.txt has never removed a site from AI Overviews, and Google's crawler documentation has always said so. Until now there was no lever that did; that is what actually changed this week.
The part nobody's switch controls
All three levers are Google's. None of them reaches ChatGPT, Perplexity, Claude or Copilot — and for a local business, those are where the buyer questions get asked. Our production corpus is exactly that population: 1,054 completed answers across 178 audits in dentists, med spas, personal-injury law and home services, asked of ChatGPT and Perplexity. 537 of those answers carried at least one URL, citing 1,115 distinct domains. Not one of those citations is affected by anything in the table above.
We also checked how much the existing crawler lever is even used by the sites the engines actually read. Taking the 20 most-cited domains in that corpus and parsing their robots.txt with `ops/robots_rules.py` (the parser we shipped on 2026-07-30, which reads the rule, not just the group name):
| Reading, 2026-08-01, top 20 cited domains | Count |
|---|---|
| Measurable (HTTP 200, `text/plain`, no `<html`) | 19 of 20 — zocdoc.com returned 403 and is UNMEASURED |
| Name `Google-Extended` at all | 4 of 19 |
| — blocks it outright | medspascout.com (cited in 63 answers) |
| — partial rules | medicalspalocator.com (32 answers), indeed.com |
| — names it to allow | discovermedspa.com (30 answers) |
| No `Google-Extended` group whatsoever | 15 of 19 — including birdeye.com (143), bbb.org (92), bestprosintown.com (82) |
So the directories winning your category's citations have, with four exceptions out of nineteen, never touched the one AI control that existed — and they are cited constantly by an engine Google does not operate. Whatever you decide about the new switch, it is not the decision that determines whether AI recommends your business.
Should a local business opt out? Almost certainly not
- The asymmetry is brutal. A publisher opting out is protecting article traffic that an AI Overview would have absorbed. A med spa, a dental practice or a law firm has the opposite problem: it is not being named in the answer at all. Excluding yourself from a surface you are struggling to enter buys you nothing and forecloses the upside.
- It is all-or-nothing at the property level. There is no page-level version of this control today. You cannot keep your service pages in AI Overviews and pull your blog out.
- Measure before you touch it. Google's own Search generative AI performance report in Search Console is the free input to this decision — with the caveat we documented when it launched: it reports impressions, not clicks, so it tells you how visible you are inside AI features, not what they send you. Read that number first; the switch is reversible but re-inclusion takes days and is subject to caching.
- If the worry is training rather than appearance, you already had the lever — `Google-Extended` — and it costs you nothing in Search by Google's own statement. Reaching for the new control to solve a training concern removes you from answers your customers see, which is not what you wanted.
What this does not say
- We have not observed the control on our own property. Google's page says it is rolling out to a subset of owners; everything above about its behaviour is quoted from Google's documentation, not from a switch we have flipped and measured.
- The 1-2 day exclusion window is Google's claim, with its own caching caveat attached. We have not timed it.
- The corpus is local-business questions on ChatGPT and Perplexity. Google's AI Overviews and AI Mode are not in it, so nothing here measures how much traffic an opt-out would cost you inside Google.
- `data-nosnippet` is not in the table because Google's robots meta documentation does not state its effect on AI Overviews or AI Mode, and we will not infer one.
How do I opt out of Google's AI Overviews?
As of 2026-08-01 there is a dedicated control: Settings → Search generative AI in Google Search Console, rolling out to a subset of website owners. Setting it to exclude removes your site from AI Overviews, AI Mode and the generative AI features in Google Discover, within 1-2 days per Google's documentation. It is property-level and all-or-nothing, and Google states it is not used as a ranking or inclusion signal for the rest of Search.
Does blocking Google-Extended remove me from AI Overviews?
No, and it never has. Google's crawler documentation states that Google-Extended controls whether your content may be used for training future Gemini models and for grounding in Gemini apps and Vertex AI, and that it does not impact a site's inclusion in Google Search nor act as a ranking signal. The Search generative AI control in Search Console is a separate lever with a separate scope.
Will opting out of Google's AI features hide me from ChatGPT or Perplexity?
No. All of Google's controls — the Search Console generative AI setting, nosnippet, max-snippet and Google-Extended — govern Google's own surfaces. ChatGPT, Perplexity, Claude and Copilot are unaffected. In our corpus of 1,054 AI answers about local businesses, 537 carried citations spanning 1,115 distinct domains, none of it governed by any Google switch.
Should a small local business opt out of AI Overviews?
In most cases no. The opt-out protects sites whose traffic an AI answer would absorb. A local business usually has the opposite problem — it is not named in AI answers often enough. Check the free Search generative AI performance report in Search Console first to see how visible you already are inside AI features, bearing in mind that report shows impressions rather than clicks.
Can I opt out of AI features on some pages only?
Not with the new control, which is property-level. The only page-level lever Google documents as affecting AI Overviews and AI Mode is nosnippet or max-snippet in the robots meta tag — but those also suppress or shorten your ordinary search snippet, so they are not a way to leave AI while keeping the blue-link preview intact.
The takeaway
Google shipped the lever publishers have asked for since AI Overviews launched, and it is cleanly scoped: appearance only, Google's surfaces only, no ranking side-effect. For most local businesses it is the wrong lever pointed at the wrong problem — the constraint is not that AI shows you too much, it is that it does not show you at all, on questions your buyers ask in engines this switch does not touch.
The free 60-second check asks ChatGPT one of your buyers' real questions and shows you whether you are named. The $79 audit runs 25 questions across ChatGPT, Perplexity, Gemini and Claude, three times each, and returns the citation source map — the exact third-party pages the engines pulled from. Agencies auditing a book of clients can run five at once with the $249 Agency 5-pack.
