Appearing in Google AI Overviews (AIO) means becoming a cited source in the summary generated by Gemini at the top of Google results. It relies on content structured as short, sourced answers, marked up with Schema.org, and published on a domain already well-positioned in traditional SEO. AIOs now cover approximately 48% of tracked queries as of Q4 2025-Q1 2026, up from 31% in February 2025 (BrightEdge, 2025-2026). This guide gives you the complete method, the 8 GEO actions to apply and the mistakes to avoid to become a source cited by Google's AI in 2026.
Key Takeaways
Google AI Overviews are the Gemini-generated summaries displayed at the top of search results, which answer the user's query directly by drawing on multiple web sources. Officially launched in May 2024 in the United States, they covered approximately 48% of tracked queries at the 2025-2026 turn, up from 31% in February 2025 (BrightEdge, AI Search 2025).
The rollout accelerated in 2025. Google's AI Mode, which extends AIOs into a conversational experience, was expanded to over 200 countries and territories in October 2025, with 35 new languages including French, Dutch and German (Google Blog, October 2025). Belgium switched on AIO and AI Mode in that wave, alongside the Netherlands, Germany, Spain, Portugal, Italy, Ireland and the United Kingdom. France, on the other hand, remains excluded to date, which creates a strategic asymmetry for French-speaking brands.
Coverage varies widely by sector. Healthcare triggers an AIO on 88% of queries, education on 83%, B2B Tech on 82% and restaurants on 78%, against only 5% in finance (BrightEdge, 2025). Informational and educational sectors are the most exposed.
Our field observation. Across the audits we've run in Belgium since the local rollout in October 2025, we see that brands that had already invested in an FAQ and answer-first structure before the AIO launch are the ones capturing the first citations. You can catch up, but it costs 2 to 3 times more editorial effort.

The AIO effect on traffic is documented and brutal. The Seer Interactive study from September 2025, conducted on 3,119 informational queries and 25 million impressions, measures a 61% drop in organic CTR on queries displaying an AI Overview, and a 68% drop in paid CTR (Search Engine Land / Seer Interactive, 2025). When the user has their answer at the top, they no longer scroll down.
But the reverse is also true, and it's the central argument for investing in AIOs. A page cited as a source in an AIO gets +35% organic clicks compared to a non-cited page on the same query, and +91% paid clicks according to the same Seer study. The gap between "cited" and "not cited" becomes the new Google visibility ratio.
User behavior shifted in parallel. On Google, the zero-click search rate went from 56% to 69% in one year following the massive AIO rollout (SimilarWeb, July 2025). News publishers saw their organic traffic fall from 2.3 billion to 1.7 billion monthly visits, meaning 600 million visits lost in a few months.

Google selects AIO sources in two stages. First, a classic Search ranking selects 10 to 30 candidate pages for the query, based on traditional SEO signals (authority, relevance, freshness, user experience). Then a Gemini evaluation picks from that pool the most extractable and reliable passages to compose the synthesized answer. This double layer means good SEO is a prerequisite, but not enough on its own.
Three families of signals weigh in the LLM's final selection:
To understand the selection mechanics in depth, read our dedicated article How AI chooses its sources: mechanisms and strategies.
Our field reading. Across 18 AIO audits conducted in the first quarter of 2026, cited pages shared a systematic trait: a first paragraph per section that delivers the answer completely, autonomously and with sources. Pages that "build suspense" before answering are never cited, even when they rank better in traditional SEO.
An effective GEO strategy for AIOs rests on 8 concrete actions we systematically apply at our clients. Princeton's academic study on 10,000 queries demonstrated that applying these levers together can increase visibility in generative engines by +40% on average (Aggarwal et al., KDD 2024). Here's the sequence to follow, in order of priority.
This is the most profitable action. Each H2 should open with a 40-to-80-word paragraph that directly answers the title's implicit question, autonomously and with sources. LLMs primarily extract these self-sufficient blocks. For the full method, see our guide Structuring an Answer-First page to get cited by AI.
The FAQPage, HowTo, Article, Organization and Person schemas help Google parse your content cleanly. They aren't a direct ranking signal, but they make extraction by Gemini easier. Our complete Schema Markup guide for GEO details the priority tags.
FAQs are the most citable blocks in existence. A 4 to 6 question FAQ, phrased the way users actually ask them, with 50-to-90-word answers, becomes a reservoir of extractions for AIOs. See FAQ GEO: build FAQs that AI actually picks up.
Bulleted lists, comparison tables and boxed definitions are over-represented in AIOs. When your content presents information in structured form, Gemini can copy-paste it as is.
AIOs favor recent content on time-sensitive queries. A visible update date (ISO datetime + human-readable text), real data refreshes, and a visible changelog boost citation chances.
Identified author with biography page, listed certifications, external third-party mentions, citations in specialist press: E-E-A-T remains a major signal. See our deep dive E-E-A-T and AI: becoming the source cited by generative engines.
A coherent thematic internal linking structure (pillar cluster + spokes) helps Google understand your expertise scope. Spoke pages reinforce the pillar's authority, which becomes the priority candidate for AIOs on main queries.
Publication date, last update date, sources cited with URL and name: anything that makes your page verifiable by a human reinforces its credibility in the LLM's eyes. Pages without dates and without sources are systematically penalized.
To apply these 8 actions to your site without managing the technical complexity, our team offers a 12-week GEO sprint dedicated to AIOs.
AIOs show a clear preference for four formats. According to BrightEdge analysis on hundreds of thousands of queries in 2025-2026, more than 70% of AIOs contain at least one bulleted list, table or boxed definition as a structuring element (BrightEdge, 2025). Long narrative content is under-represented among cited sources.
Here are the formats to prioritize in your AIO target pages:
Beyond format, the writing style matters. Short sentences (15 to 20 words), active voice, precise vocabulary (no marketing-speak), and every strong claim backed by a source. That's the grammar of extractability.
Google now offers two distinct AI interfaces. AI Overviews are the generated summaries displayed above traditional results, AI Mode is a complete conversational experience where the user talks to Gemini without a list of blue links. AI Mode was extended to 200+ countries in October 2025, including Belgium, with 35 new languages covered (Google Blog, October 2025).
Both interfaces share the same engine (Gemini) and draw on the same Search index, but they differ on three key points:
For brands, the consequence is clear: optimizing for AIOs and for AI Mode requires the same editorial foundation, but AI Mode amplifies the importance of depth and thematic linking. For details on AI-Mode-specific actions, see our guide Google AI Mode: what it changes for your visibility in 2026.
Measuring your AIO presence is still imperfect, but three complementary approaches give an actionable view. Google announced in late 2025 an "AI Overviews" segment in Search Console, which should allow filtering AIO-originated impressions and clicks on markets where they're deployed. Pending full generalization, steering relies on third-party tools and manual testing.
Three indicators to track in monthly steering:
For the full method and the tools we use in-house, see our deep dive AI citation monitoring: complete guide to steer your visibility.
Our field observation. Across 12 B2B brands monitored on AIO since November 2025, the Share of Model gap between answer-first optimized pages and classic pages is 3 to 5 times in favor of the former. Monthly tracking isn't a luxury: it's what transforms a GEO intuition into industrial steering.
Five recurring mistakes prevent brands from appearing in AIOs, even when they rank well in SEO. According to our internal PingPrime data on 27 audits in 2025-2026, 68% of brand content is not extractable by LLMs due to inadequate structure, whereas in 80% of cases, the topic is already well covered, just poorly presented. Here are the classic pitfalls to fix first.
FAQPage or HowTo on eligible pages, you leave Google guessing your structure rather than telling it.For the full panorama of the most costly GEO mistakes, see our deep dive GEO in 2026: the 5 mistakes 90% of brands make.
The first signals appear in 4 to 12 weeks after setting up answer-first pages and Schema markup. But only 30% of cited brands remain stable from one AIO run to the next (AirOps, 2025). Steering must be monthly: AIO citation volatility forces continuous tracking, not one-shot optimization.
Yes, it's a prerequisite. Google first selects 10 to 30 candidate pages via its traditional Search ranking, then Gemini picks from that pool. Without an organic Top 10 on the query, your page has no chance of being cited in the corresponding AIO. GEO doesn't replace SEO: it layers on top of it to turn a good position into an effective citation.
No, as of May 2026 France remains excluded from AI Overviews and AI Mode, unlike Belgium, the Netherlands and most other European countries. The expansion of Google AI Mode to 200+ countries and 35 new languages in October 2025 (Google Blog, 2025) notably bypassed France, which creates an asymmetry for French-speaking brands working both markets.
Three complementary methods: direct manual testing on Google from a Belgian account, tracking via third-party tools (Otterly, Profound, AthenaHQ), and reading the "AI Overviews" segment in Search Console (currently rolling out). Across 12 B2B brands tracked since November 2025, we observe that answer-first optimized pages multiply their Share of Model by 3 to 5 versus classic pages.
The base is shared (answer-first, sourcing, Schema, FAQ, freshness), but the weightings differ. ChatGPT cites Wikipedia at 47.9% and favors established media. AIOs rely on the traditional Search ranking, so domain authority counts more. Only 11% of domains are cited by both ChatGPT and Perplexity according to the 5W AI Citation Source Index 2026, which justifies a multi-platform approach.
Google AI Overviews have redrawn the Google visibility map in 18 months. With 48% of queries covered on average, a 61% drop in organic CTR on informational queries, but +35% clicks when you're cited, the balance clearly tips toward brands that invest in GEO. The Belgian rollout of October 2025 has opened a 12-to-24-month window where pioneering brands can capitalize before the competition catches up.
The actions are identified: answer-first, Schema, FAQ, freshness, E-E-A-T, internal linking, visible dates, rigorous sourcing. Performance figures are measurable. Monitoring tools exist. What's left is rigorous and continuous execution.
