You can opt out of Google's AI Overviews now. Here is what the switch does and does not touch.

On 31 August 2026 Google rolled out a switch in Search Console that removes a site from AI Overviews, AI Mode and the generative AI features in Discover.

It sat there quietly for five weeks. Then on 6 October Search Engine Roundtable noticed Google had added a line to the help page about properties overriding each other.

Google's autocomplete already finishes "google ai overviews opt out", "opt out of ai overview google" and "can i opt out of ai overview on google". People want this switch.

Here is the complication. NovaTechRay exists to get businesses named inside AI answers. A one-click way out of the largest of them is either the most important setting in Search Console or one to leave alone. It depends on what it costs, and the help page says more about that than most coverage did.

Everything below is from Google's help page, "Search generative AI control", read on 8 October 2026.

Step 1: Where it is and what the three choices are

In Search Console it lives under Settings, then Search generative AI.

The page lists three options.

1. Include. Your content can appear in the features, as links and as grounding for AI responses. This is the default for all properties.
2. Exclude. Your content is prevented from being visible in the features, including being linked or used for grounding. In Google's words, "You won't receive any traffic or impressions from these features."
3. Inherit control from parent. The default if your property sits under another one.

The page also says the feature list is expected to change "over time". Today it is three surfaces. It may not stay three.

Step 2: What excluding does not do

This is the part people get wrong, so here are the help page's own limits.

It is not a ranking signal. The page says the control "isn't used as a ranking or inclusion signal affecting other parts of Search."

It does not stop training. "This control doesn't affect AI training," the page says, and points to Google-Extended for that.

It does not stop Google using your pages to understand language. Your content "may still be used to power Google Search as a whole."

It does not override Merchant Center or Google Ads participation.

And it does not remove you from Search. That is noindex.

So the switch is narrow. It removes you from three answer surfaces and nothing else.

Step 3: What you lose, and what you do not get back

Google says content from other sites "will still be available in those features, and it may appear similar to yours."

Read that slowly. Excluding your site does not remove the answer. It removes you from the answer.

If a competitor's page covers the same question, the AI Overview still answers it, with their link. Your opt-out becomes their citation.

That is the contrarian line for this post. Opting out rarely protects anything.

There are real exceptions, and I will not pretend otherwise. A publisher whose business is the click, losing traffic to summaries of its own reporting, has a case. A site with content it cannot have paraphrased for legal or medical reasons may have one too. For a business that wants to be recommended, it is a way to make a competitor the default.

If you are weighing it anyway, ask three questions first.

1. Does the AI answer for your main queries cite you today? The Generative AI performance report will show impressions by page.
2. Would a competitor's page answer the same question if yours were gone?
3. Is the problem the summary itself, or a specific page? A page-level problem has page-level tools.

If the honest answers are yes, yes and one page, the site-wide switch is the wrong tool.

Step 4: The inheritance trap

The help page spends more words on inheritance than on anything else, and the 6 October edit is about it.

A property inherits the setting of its closest parent that has been manually configured. If none has, it inherits from the top-level domain property.

So a domain property for example.com governs https://example.com/blog/ unless someone set the blog property separately.

Here is how that goes wrong. Picture an agency that verifies a URL-prefix property for one folder, flips the switch to test something, and forgets. The rest of the site is in AI Overviews. That folder is not.

Google's fix, added on 6 October: "Owners of the top-level domain property will see a notification on the Search generative AI control page when one of their child properties overrides the parent setting."

That only helps if someone owns the domain property and looks.

Two checks for any site you run:

1. Confirm the business owns the top-level domain property, as well as any URL-prefix one.
2. Open the control page on the domain property and look for that notification.

Step 5: How long a change takes

The page says a change "generally takes a few days." Content is excluded within one to two days after the control goes live, and "some content may take longer" because of caching.

There is no stated time for switching back on. Assume it is no faster.

So do not flip it to see what happens. Use the Generative AI performance report first. NovaTechRay covered what that report counts and what it leaves out: impressions by page and date, with no query column. Look at which pages earn AI impressions before you decide those impressions are worth nothing.

Step 6: Two older pages this corrects

On 21 September NovaTechRay wrote that, outside one market's negotiated settlement, the general tools for limiting AI Overviews were the nosnippet and max-snippet directives. The global control had already shipped on 31 August. That answer was out of date when it went up. The post is flagged for a correction note.

The VALORAE group's platform rules register, which tracks 13 outside rule pages with the date each was last read, lists the snippet controls under Google's AI features page. Those directives still work, page by page. The site-wide switch is now the simpler tool for a whole site, and the register should say so.

The short version

• Search Console's Search generative AI control has been live for every site since 31 August 2026.
• Exclude removes you from AI Overviews, AI Mode and Discover's AI features, and nothing else.
• It is not a ranking signal and it does not stop AI training. Google-Extended handles training.
• Excluding removes you from the answer, not the answer itself. Competitors fill the gap.
• Own the top-level domain property and check it for override notifications.
• Read the Generative AI performance report before changing anything.
• Allow a few days for any change to take effect.
