Google AI Search opt-out controls are now available to website owners worldwide through Search Console. Google says the control lets a verified owner decide whether a site may appear in and help ground responses in generative AI Search features.
The decision has a direct trade-off. A site that opts out will not receive impressions or traffic from Google features such as AI Overviews, AI Mode or AI Overviews in Discover. Before changing the setting, website owners should measure current visibility, confirm who has authority to decide and understand how this control differs from other crawler and snippet directives.
What Google rolled out worldwide
Google announced the control and new Search Console insights in June 2026, initially for a subset of UK websites. Its website-owner controls announcement was updated to state that the features reached all websites worldwide on 31 August 2026.
The Search Console toggle covers inclusion in generative AI Search features and whether site content may help ground their responses. The accompanying performance reports show visibility information such as impressions, appearing pages and countries. Availability does not mean every website is receiving meaningful AI visibility, so check the property’s actual data before drawing conclusions.
What happens when a site opts out
Google says opted-out sites will not appear in or help ground its generative AI Search responses. They will therefore stop receiving impressions and visits from the affected AI features. The control applies to AI Overviews, AI Mode and AI Overviews in Discover as described in Google’s announcement.
This is more than a cosmetic preference. It can change how people discover a publisher, product or service while using conversational search. Any decision should consider referral traffic, assisted conversions, brand visibility, content rights, commercial partnerships and the organisation’s policy on AI presentation.
What the opt-out does not change
Google states that the toggle will not be used as a ranking signal for results outside its generative AI Search features. Opting out of AI responses is therefore not the same as applying noindex or removing a page from regular Google Search.
Do not assume the control guarantees a ranking benefit or penalty elsewhere. Continue maintaining crawlable pages, useful content, accurate metadata and a good page experience for normal Search. Kayaar’s 60-minute website SEO audit provides a wider technical review that remains relevant whether the AI toggle is on or off.
A decision framework before changing the setting

Question
Evidence to record
Visibility
Where does the site currently appear?

Landing-page engagement, leads, sales or subscriptions
Rights
Are there contractual or licensing concerns?
Publisher terms, partner agreements and legal advice
Authority
Who can approve a site-wide decision?
Named owner, stakeholders and approval record
Monitoring
How will the effect be evaluated?
Change date, baseline, review window and guardrails
Measure a baseline in Search Console
Export the generative AI performance report before changing the toggle. Record at least four full weeks where sufficient data exists, separated by Search and Discover. Review which pages appear, where impressions occur and whether any meaningful business actions follow.
Kayaar’s Search Console AI performance report guide explains the available dimensions and a practical reporting workflow. Do not treat impressions as revenue. Connect the report with analytics and conversion evidence while respecting consent and attribution limits.
Note campaigns, redesigns, technical incidents and content launches that may distort the baseline. A before-and-after comparison is only useful when the team can distinguish the toggle from unrelated changes.
Google AI Search opt-out versus Google-Extended
The Search Console toggle and Google-Extended are different controls. The new toggle manages participation in generative AI features within Google Search. Google-Extended is a robots.txt product token covering whether crawled content may be used for training future Gemini models and for grounding in Gemini Apps and Grounding with Google Search on Vertex AI.
Google’s Google-Extended documentation says that token has no effect on Google Search and is not a Search ranking signal. It also has no separate crawler user agent; existing Google user agents perform the crawling while the token acts as a control.
Document both settings independently. Changing one and assuming the other changed can leave the organisation with a policy it did not intend.
Do not confuse the toggle with snippet controls
Snippet directives manage what Google may display from an indexed page in search-result snippets. They serve a different purpose from a site-level decision about participation in generative AI Search. Similarly, noindex removes a page from Google Search rather than only excluding it from AI features.
Inventory existing nosnippet, max-snippet, data-nosnippet, robots and indexing rules before making changes. Conflicting or poorly documented controls make later diagnosis difficult, especially on sites with several content-management systems or deployment teams.
How to review the decision safely
Confirm Search Console ownership and obtain stakeholder approval.
Export current AI visibility and conversion evidence.
Record the business, rights and audience reasons for the decision.
Change only the intended control and document the date.
Monitor AI visibility, overall organic traffic and business outcomes.
Use a predetermined review window instead of reacting to one day’s movement. Google’s reporting can take time to reflect changes, and organic demand can vary independently. Kayaar’s Google AI Mode content workflow offers practical guidance for sites that remain included and want to improve usefulness without chasing unsupported AEO shortcuts.
When remaining included may make sense
A business may value AI visibility when the pages attract relevant discovery, assist conversions or strengthen authority. Publishers may also benefit when prominent links introduce new readers. Remaining included does not guarantee impressions or clicks, but opting out removes that opportunity from the covered features.
Sites that remain included should focus on original, expert-led and well-structured content. Kayaar’s Google Preferred Sources guide explains another audience-led discovery feature, although it does not replace the AI Search inclusion decision.
Key takeaway
The Google AI Search opt-out is a meaningful website-governance choice, not an SEO hack. Measure the current opportunity, separate it from Google-Extended and indexing controls, obtain authority and document the outcome. If your organisation needs an independent technical and commercial review, contact Kayaar.
FAQs
What is the Google AI Search opt-out?
It is a Search Console control that lets website owners decide whether their site can appear in and help ground Google’s generative AI Search features.
Does opting out remove a site from regular Google Search?
No. Google says the control is not used as a ranking signal outside its generative AI Search features.
What traffic can a website lose after opting out?
Google says opted-out sites will not receive impressions or traffic from the affected generative AI features, including AI Overviews, AI Mode and AI Overviews in Discover.
Is Google-Extended the same as the AI Search opt-out?
No. Google-Extended controls specified Gemini training and grounding uses outside Search, while the Search Console toggle manages generative AI features within Google Search.
Should every website opt out of Google AI Search?
No universal answer applies. Review visibility, business value, rights, stakeholder policy and the expected loss of AI Search traffic before deciding.
