In brief
- AI Overviews (AIO) are active globally since 2025 and cover primarily informational queries.
- They rely on the classic Google index: strong rankings remain the most important prerequisite.
- Cited sources are selected at passage level, not page level: each H2 section is a distinct candidate.
- FAQPage and HowTo schemas improve how AIO can structure your content.
- Google Search Console now displays a separate AIO report to measure impressions and clicks.
How AI Overviews work
AI Overviews appear at the top of Google SERPs for certain queries, before classic links. Google generates a synthetic answer drawing from sources selected from its index, which it cites with a card (title + domain + favicon).
Source selection follows a two-step mechanism:
- Qualification: Google filters sources by domain authority, thematic relevance and editorial quality.
- Passage extraction: from qualified pages, the system extracts specific passages (equivalent to RAG chunking) and uses them to generate the answer.
Which queries trigger an AI Overview
Not every Google query generates an AI Overview. Trigger patterns observed in 2026:
| Query type | AIO frequency | Examples |
|---|---|---|
| Long informational | Very high | "how to optimise a site for AI", "what is GEO" |
| Definitional | High | "GEO definition", "what is RAG" |
| Comparative | High | "difference between Perplexity and ChatGPT" |
| Procedural | High | "how to configure robots.txt for AI bots" |
| Pure transactional | Low | "buy SEO training", "SEO audit price" |
| Sensitive or YMYL | Very low | Health, law, personal finance |
| Local | Low | "SEO consultant London" |
Source selection criteria
1. Domain authority
This is the most discriminating filter. Studies from Search Engine Land, Ahrefs and Semrush on AI Overviews show that cited sources are very often in the top 10 for the relevant query. The correlation with Domain Rating / Domain Authority is strong. A new site without notable backlinks will rarely be selected, even with excellent content.
2. Thematic relevance and query coverage
Content must precisely answer the query. A generalist page that mentions the topic will not be preferred over a specialist page that covers it exhaustively. Each H2 should correspond to a sub-aspect of the query.
3. Quality and self-containment of the passage
Google extracts passages, not pages. The selected passage must be:
- Readable without surrounding context (self-contained).
- Factual and dated if the claim is temporal.
- Concise: between 2 and 6 lines is ideal for observed extractions.
- Unambiguous on the topic (avoid pronouns without a clear referent).
4. Freshness
On evolving topics (tech, health, legal), AIOs prefer recently updated sources. A page untouched for 24 months will lose ground to a competitor who updates content regularly. The update date must be visible and authentic in the HTML.
5. E-E-A-T signals
Experience, Expertise, Authority, Trust. Google continues to weight these signals in AIO selection: a complete About page, identified author, cited sources, schema Organization with sameAs, backlinks from thematically related sites.
Actionable optimisation levers
Rework H2 sections as "micro-answers"
Each section of your page must be able to function as a standalone answer to a question. Rephrase your H2s as implicit or explicit questions. Add a short answer paragraph (2-3 sentences) immediately after the H2, before going into details.
Add FAQPage schema on informational pages
The FAQPage schema structures your questions and answers in a way that is readable for Google. On pages covering frequently queried topics, integrate a FAQ section at the bottom of the page with 3 to 6 precise questions and self-contained answers. Associate the corresponding JSON-LD schema.
Target long-tail queries with reliable AIO triggering
Queries of the type "how + verb + object" very regularly trigger AIOs. Identify the 10 to 20 strategic queries for your domain and test which ones generate an AIO. Focus energy on those.
Maintain a visible and authentic update date
Pages without a visible date or with a date more than 18 months old on evolving topics are penalised. Update the content of strategic pages every 6 months, even to correct a figure or add an example. The date in the HTML (the dateModified attribute in the Article schema) must correspond to a real update.
Strengthen E-E-A-T authority
Publish or complete your About page: who you are, what your expertise is, since when. Add an Organization schema with sameAs pointing to LinkedIn, GitHub, Wikidata. Link to recognised sources. Earn backlinks from specialist sites in your domain.
Measuring your presence in AI Overviews
Google Search Console has offered a dedicated "AI Overviews" report accessible under the Performance tab since 2025. It shows:
- AIO impressions: how many times your site was cited in an AI Overview.
- Clicks from AIO: how many clicks were generated to your site from that surface.
- Pages and queries: which content is cited and for which queries.
Complement with manual monitoring: test 10 strategic queries regularly in Google Search in incognito mode (browser without cookies, to avoid personalisation). Note who is cited and the position of your site.
Two concrete optimisation cases
Case 1: B2B SaaS blog that does not appear
Typical diagnosis: articles too long with no clear H2 structure, no FAQPage schema, publication dates visible but never updated since 2023. Actions: rework the 5 main articles with question-format H2 sections, add a FAQ at the bottom of each article, update dates after real content updates. Observable result in 4 to 8 weeks in GSC.
Case 2: E-commerce site appearing on guides but not product pages
Normal: AIOs are rare on pure transactional queries ("buy", "price"). Product pages are not meant to generate AIOs. The opportunity lies in buying guides, comparatives, and category definitions. Create a "guides" or "advice" section distinct from product pages.
AI Overviews optimisation checklist
- Site ranked in the top 10 for target queries (SEO prerequisite).
- Each H2 rephrased as a query intent, not a decorative title.

- Article schema with dateModified up to date and author/publisher filled in.
- Update date visible in the HTML and authentic.
- Complete About page with Organization schema and sameAs.
- AI Overviews report monitored monthly in Google Search Console.
- Manual test on 10 strategic queries twice a month.
Frequently asked questions
Are AI Overviews active globally?
Yes. Google broadly deployed AI Overviews in 2025. They appear primarily on informational queries, but triggering remains selective: not every query generates an AI Overview. Pure transactional, sensitive or local queries rarely trigger one.
Do you need a top ranking to appear in AI Overviews?
Not necessarily top 3, but a significant presence in the Google index is required. Available studies show that cited sources are very often in the top 10 for the relevant query. A site without reasonable domain authority will rarely be selected.
Can you see your AI Overviews impressions in Google Search Console?
Yes. Google Search Console has a dedicated AI Overviews report showing impressions and clicks generated from that surface.
Does schema.org FAQPage help to appear in AI Overviews?
Yes, marginally. The FAQPage schema improves the readability of your question-and-answer structure for Google. However, domain authority and editorial quality are the dominant factors.
