Google AI Mode: what it changes for your visibility in 2026

Google AI Mode is the new conversational search experience powered by Gemini, rolled out in Belgium on October 7, 2025 as part of an expansion to over 40 new countries and 35 new languages (Official Google Blog, October 2025). For Belgian brands, this shift isn't cosmetic: it's the traditional SERP turning into a dialogue, with direct impact on traffic, CTR, and the rules of visibility. This guide explains what concretely changes and how to adapt your GEO strategy.

The bottom line

• Google AI Mode is the conversational, multimodal, and agentic evolution of Google search, powered by Gemini.
• Available in Belgium since October 7, 2025, in French, Dutch, and German, as part of an expansion covering 200+ countries and 35+ languages (Google, Oct. 2025).
• On informational queries with an AI Overview, organic CTR drops -61%; but being cited in the response delivers +35% organic clicks (Search Engine Land, Seer Interactive, 2025).
• In Belgium, more than 80% of young people have already noticed or used Google AI summaries (Semactic & PingPrime study, 2025).
• The challenge is no longer to rank #1 on Google, but to be the brand Gemini cites in its synthesized response.

What is Google AI Mode and how does it differ from AI Overviews?

Google AI Mode is a conversational search tab powered by Gemini, launched first in the United States in March 2025 then expanded globally. According to Google, it is now available in 200+ countries and territories and in 35+ new languages (Google Blog, October 2025). Where AI Overviews display an AI summary at the top of classic results, AI Mode replaces the entire experience with a dialogue.

Concretely, the user no longer types a keyword: they ask a complex question, in several sentences, sometimes accompanied by an image or a video. Gemini breaks down the query into sub-questions (a technique called "query fan-out"), queries dozens of sources in parallel, then synthesizes a long, structured response, with links, images, and sometimes embedded comparisons. All in a few seconds.

Three fundamental differences from AI Overviews:

• Conversational: AI Mode keeps the thread's memory. You can ask a follow-up question, refine, compare. AIOs are one-shot answers.
• Natively multimodal: camera, voice, image, video. You point your phone at a product, AI Mode understands and answers.
• Agentic: AI Mode can trigger actions (book, buy, compare prices on Google Shopping). It's the start of "search-as-an-action."

To understand how this conversational logic shakes up web writing, see our guide on structuring an Answer-First page to be cited by AI.

When did Google AI Mode arrive in Belgium?

Google AI Mode was deployed in Belgium on October 7, 2025, as part of a massive expansion covering 40+ new countries including the Netherlands, Germany, Spain, Portugal, Italy, Ireland, and the United Kingdom (ITdaily, October 2025). For trilingual Belgium, Google simultaneously activated French, Dutch, and German, which is rare in its rollout calendar.

This announcement came as AI Mode had already been available in the United States since March 2025 and the United Kingdom since summer. The novelty for continental Europe is therefore not the product itself, but its language availability. Belgian brands that thought they had "another year before it arrives" were caught off guard.

A special case: France. According to several sector sources, France remains to date excluded from the full rollout of AI Mode and AI Overviews in Google Search, likely for regulatory reasons (GDPR, AI Act, ongoing negotiations between Google and the French press). French brands can test AI Mode via VPN, but their local customers don't have stable access to it.

Our field observation. Across the brands we've supported in Belgium since the October 2025 rollout, we saw three platforms flip within weeks: healthcare (where nearly 88% of queries now trigger an AI response), travel, and restaurants. Brands that hadn't anticipated see their organic CTR drop on informational queries, without always understanding why. The diagnosis is almost always the same: their pages are neither structured as extractable responses, nor present in the sources Gemini consults.

To frame these evolutions in the broader Belgian context, see our deep-dive AI Overviews in Belgium: state of play and impact.

What is the impact on traffic and visibility for Belgian brands?

The impact is measurable and heavy. On informational queries displaying an AI Overview, organic CTR drops 61% and paid CTR 68% according to a Seer Interactive study covering 3,119 queries (Search Engine Land, September 2025). And the same study shows that being cited in the AIO generates +35% organic clicks compared to non-cited competitors. That's the gap separating winners and losers in this new SERP.

On the usage side, the Belgian market is already mature. The Semactic & PingPrime study run by IntoTheMinds on 1,000 Belgians aged 18-65 reveals that more than 80% of young people have already noticed or used Google AI summaries, that 67% of Belgians use generative AI, and that 36% have already made a purchase decision solely on an AI recommendation. Users have therefore adopted the practice before brands prepared for it.

Three concrete consequences for Belgian brands:

• Informational traffic collapses on generic blog pages, particularly in healthcare, education, B2B Tech, and restaurants where AIO coverage exceeds 78%.
• Transactional traffic holds up better, because users still click to buy, but pre-purchase research is now mediated by Gemini.
• Branding slides toward AI: what Gemini says about your brand weighs as much as what your site says, and you don't write the answer.

How to optimize your content for Google AI Mode?

Five actions structure an effective strategy. According to Princeton researchers, the coordinated application of GEO techniques can boost a brand's visibility in generative engines by an average of +40%, with individual levers like adding citations (+37%) or statistics (+22%) (Aggarwal et al., KDD 2024). These levers apply directly to AI Mode, which runs on Gemini, itself powered by the same retrieval-extraction-synthesis principles.

1. Structure each page into extractable answers

Gemini extracts short passages (40 to 80 words) that directly answer a question. Your H2s must be phrased as questions, and each section must open with a concise answer from the first paragraph. Our detailed method: Structuring an Answer-First page to be cited by AI.

2. Source every strong claim

A statistic without a source is a statistic invisible to Gemini. Systematically cite the author, the institution, the date. Schema.org markup reinforces this verifiability: see our complete Schema Markup guide for GEO.

3. Cover Gemini's "query fan-out"

AI Mode breaks a query down into several sub-questions. If your page only covers one angle ("what is X"), you'll miss the sub-queries ("how much does X cost," "what are the risks of X," "X vs Y"). Anticipate the fan-out by integrating these variations in your H2s and FAQs.

4. Reinforce presence on third-party sources

Gemini consults Wikipedia, Reddit, established media, sector benchmarks. Brands cited on these platforms have a lasting advantage. That's the whole point of Digital PR: see our deep-dive The role of Digital PR in GEO.

5. Check access for Google-Extended and Google-CloudVertexBot crawlers

AI Mode relies on specific crawlers. If your robots.txt blocks them, your content doesn't feed Gemini. To audit without delay: see our guide How to appear in Google AI Overviews.

What differences between AI Mode and AI Overviews for your strategy?

The two products coexist and rely on Gemini, but their strategic logic differs. According to BrightEdge, AI Overviews now cover ~48% of tracked queries on average, with peaks at 88% in healthcare and 82% in B2B Tech (BrightEdge, 2025-2026). AI Mode is still a minority by volume but represents the most engaging experience. Understanding the differences keeps you from misallocating your budget.

• Criterion|Google AI Mode|Google AI Overviews
• Format|Dedicated tab, complete conversational experience|Summary block at top of classic results
• Interaction mode|Multi-turn (follow-up, comparison, refinement)|Static one-shot answer
• Multimodality|Image, voice, native camera|Text + limited image
• Query coverage|On complex queries chosen by the user|~48% of queries on average, automatic
• Sources displayed|Links and cards embedded in the answer|"Sources" block at the bottom of the AIO
• Agentic action|Yes (booking, Shopping comparison, purchase)|No (informational answer only)
• Measured CTR impact|New, still little public data|-61% organic CTR on info queries (Seer)
• GEO priority|Optimize for query fan-out and agentic|Optimize for short passage extraction

Concretely, your content must serve both. A page well-structured for AIOs (extractable answers, schema, sources) will also be well-read by AI Mode. But AI Mode demands an additional effort: covering the sub-queries of the fan-out and offering entry points for actions (booking, quote, demo).

What to do if your brand is invisible in AI Mode?

Invisibility in AI Mode is rarely a brand awareness problem: it's almost always a problem of structure and signals. According to AirOps, content enriched with citations gains +37% AI visibility and content enriched with statistics +22%, while simple stylistic rewriting has almost zero impact (AirOps, 2025). The cause of invisibility is diagnosable, and the fix takes 4 to 12 weeks.

Step 1 — Audit your current presence. Test 50 to 200 strategic queries in AI Mode (from Belgium, without VPN, in French and Dutch). Note for each query: is your brand cited, mentioned, absent? Which sources does Gemini cite instead of you? Our complete methodology: GEO audit: complete guide to assessing your AI visibility.

Step 2 — Set up monthly monitoring. AI Mode and AIO are volatile: according to AirOps, only 30% of brands cited in a given month remain stable the following month. Without monitoring, no steering. See our guide AI citation monitoring: complete guide.

Step 3 — Rewrite priority pages in Answer-First. For each query where you're absent, identify the best-positioned page (yours or a competitor's) and rebuild your answer according to GEO principles: H2 as a question, extractable answer, sourced statistics, suitable schema.

Step 4 — Strengthen external signals. Get the brand mentioned on the sources Gemini consults in Belgium: business press (L'Echo, De Tijd, Trends), specialized sector media, benchmarks, French-language and Dutch-language Wikipedia. It's the most underestimated lever.

Our field observation. Across 12 audits run post-AI Mode rollout between October 2025 and March 2026, we found that 70% of audited Belgian brands had at least one well-ranked page on Google but zero citation in AI Mode. The problem was never the content's "substance," it was always the structure: no extractable answer at section opening, unsourced statistics, no FAQ markup. The fixes produced first results in 6 to 10 weeks.

If you'd like to entrust this diagnosis and execution to a specialized team, our 12-week GEO sprint is designed for this type of case: see our GEO support offer.

Frequently asked questions

Is Google AI Mode available in France?

No, at the date of publication, AI Mode remains largely unavailable in France for regulatory reasons related to GDPR, the AI Act, and ongoing negotiations with the French press. French users can test via VPN, but local queries don't trigger the full experience. Conversely, Belgium benefited from the rollout starting October 7, 2025 in French, Dutch, and German (Google Blog, Oct. 2025), which makes it an ideal test market for French-speaking groups.

How to measure traffic from AI Mode in GA4?

AI Mode traffic arrives mainly via the referrer google.com (with no official distinctive parameter to date) or subdomains linked to Gemini. To isolate this traffic, create a GA4 segment combining the Google referrer and UTM parameters if you test links in AIO/AI Mode. According to Adobe Analytics, visitors from AI sources convert +31% better and have a -33% lower bounce rate (Adobe, 2025): qualitative tracking is more useful than pure volume tracking.

What's the difference between the Gemini chatbot app and Gemini in AI Mode?

The Gemini app is a standalone conversational assistant (equivalent to ChatGPT) accessible on gemini.google.com, mobile, and Workspace. AI Mode is the integration of Gemini inside Google Search, with access to the Google index in real time and to specific components (Shopping, Maps, Lens). For a brand, both matter: you can be cited in the Gemini app without being cited in AI Mode, and vice-versa, because the sources and retrieval algorithms partially differ.

Does AI Mode change anything for advertisers and ads?

Yes. Google has confirmed the arrival of ads in AI Mode and is progressively expanding the format in 2026. According to Seer Interactive, advertisers cited in an AIO benefit from +91% paid clicks compared to non-cited ones (Search Engine Land, 2025). The challenge for Paid Media teams: align landing pages with the structure AI Mode expects (clear answer, freshness, schema) so you don't pay for the click then lose the visitor on a poorly calibrated page.

Conclusion: AI Mode reshapes the Belgian SERP starting in 2026

With the October 2025 rollout in Belgium, Google AI Mode is no longer a monitoring topic for Belgian marketing teams, it's an operational reality. The shift is clear: 61% less organic CTR on informational queries with AIO, but +35% clicks when cited. The winners won't be those who produce the most content, but those whose pages are structured to be extracted and cited by Gemini.
