Google-Extended: Gemini training and grounding in Gemini apps — doesn’t affect Search ranking- Measurement
- Traffic from AI features is included in Search Console’s Performance report (Web)
According to Google, to be shown as a supporting link in AI Overviews or AI Mode a page only needs to be indexed and eligible to appear in Google Search with a snippet — there are no extra technical requirements or special files[1]. So good SEO + answer-first content + structured data is also the foundation for Google’s AI surfaces. Google-Extended only controls Gemini model training and grounding in Gemini apps; it does not affect Search visibility[2].
How do AI Overviews and AI Mode pick sources?
AI Overviews show a summary compiled from pages in Google’s index, with supporting links; AI Mode does the same conversationally. According to Google, both may use a query fan-out technique — issuing multiple related searches across subtopics — to build the answer[1]. That favours sites that answer the whole set of questions around a topic, not a single keyword.
| Control | Effect |
|---|---|
noindex | Page leaves Search and AI features entirely |
nosnippet / data-nosnippet | Page or marked section can’t be quoted |
max-snippet:[n] | Caps how much text can be quoted |
Blocking Google-Extended | Excluded from Gemini training/grounding; Search and AI Overviews visibility unaffected |
What should you do to appear in Google’s AI answers?
- Index first: confirm pages are indexed in Search Console and fix technical issues (SEO services).
- Build a topic cluster: around your main service page, add pages answering the sub-questions customers ask — query fan-out searches for exactly those.
- Answer-first paragraphs: the first 40–60 words under every H2 should stand alone as an answer (AEO).
- Structured data: Organization, Service, FAQPage, Article, BreadcrumbList — matching the visible text (schema guide).
- Don’t restrict snippets: remove unnecessary

How do you measure AI Overviews visibility?
Google includes traffic from pages shown in AI features in the overall Web data of Search Console’s Performance report; there is no separate “AI Overviews” filter[1]. So you need to search your target question set regularly and log which sites are shown as supporting links in the AI Overviews box — in the Neural Visibility Audit, Gemini and AI Overviews are measured as separate columns. According to SparkToro, 68% of US Google searches ended without a click in the first four months of 2026[3]; see the zero-click guide.
Frequently asked questions
01Do I need special markup to appear in AI Overviews?
No. Google’s documentation says there are no additional technical requirements for AI Overviews and AI Mode — no new machine-readable files, “AI text files” or special schema.org markup. The page must be indexed and eligible to be shown with a snippet[1]. Structured data and clear content still make the page easier to understand.
02If I block Google-Extended, will I drop out of AI Overviews?
No. According to Google, Google-Extended doesn’t affect inclusion or ranking in Google Search; it controls use for Gemini model training and grounding in Gemini apps[2].
