State of GEO in 2026: Trends, numbers and predictions

By mid-2026, GEO (Generative Engine Optimization) is no longer a niche: it has become a mandatory layer of digital visibility. Three numbers summarize the shift. ChatGPT has passed 800 million weekly users (Sam Altman, OpenAI DevDay, October 2025), 67% of Belgians now use generative AI (Semactic & PingPrime study, November 2025), and AI Overviews cover nearly 48% of Google queries (BrightEdge, 2025-2026). This report synthesizes the state of GEO at mid-2026, platform by platform and sector by sector, and delivers five operational predictions for late 2026 and 2027.

The bottom line

• Generative AI adoption has doubled in two years: 67% of Belgians, 56% according to Deloitte, 32.7% across the EU (Eurostat, Dec. 2025).
• AI Overviews trigger a 61% drop in organic CTR on informational queries (Seer Interactive, Sept. 2025).
• Visitors from AI convert up to 9x better than Google organic traffic on certain verticals.
• Five platforms structure the market: ChatGPT, Google AI Mode, Perplexity, Claude, Gemini, with only 11% overlap between their cited sources.
• Our prediction: by the end of 2027, half of B2B brands' "content" budgets will be allocated to GEO rather than classic SEO.

7 key numbers to understand the state of GEO in 2026

Seven indicators summarize the transformation underway. User adoption, the share of searches affected by AI, the drop in CTR and the jump in AI-recommendation-based purchases map out a terrain where being only ranked on Google is no longer enough. According to Bain & Company, 80% of users rely on AI summaries for at least 40% of their searches (Bain & Company, February 2025). Here is the data snapshot at mid-2026.

• Indicator|2026 value|Source
• Belgian generative AI users|67%|Semactic & PingPrime, Nov. 2025
• European generative AI users (16-74 y.o.)|32.7%|Eurostat, Dec. 2025
• ChatGPT weekly users|800 M|OpenAI, Oct. 2025
• Perplexity monthly queries|780 M|Perplexity, May 2025
• Google queries with AI Overview|~48%|BrightEdge, 2025-2026
• Belgians who purchased on AI recommendation|36%|Semactic & PingPrime, Nov. 2025
• Organic CTR drop on AIO queries|-61%|Seer Interactive, Sept. 2025

How did users shift to AI search?

The shift happened faster than expected, and it is now structural. Bain & Company estimates that 60% of searches now end without a click to an external site, vs a historical average of around 50% (Bain, February 2025). The movement is threefold: substitution, compression and rising expectations.

A massive substitution of the search journey

SimilarWeb has documented a dramatic jump: the rate of zero-click searches on Google rose from 56% to 69% in one year, following the progressive rollout of AI Overviews (SimilarWeb, July 2025). Over the same period, US publishers' organic traffic fell from 2.3 billion to 1.7 billion monthly visits, meaning 600 million visits evaporated in 12 months.

The other striking indicator: referrals from ChatGPT to news sites have multiplied 25-fold in one year. Information consumption is redistributing between the Google index (which is shrinking) and LLMs (which are exploding), without the overall "information consumed" volume dropping.

In Belgium: a generational leap

Our joint study with Semactic, conducted by IntoTheMinds with 1,000 Belgians and 312 professionals, shows that 76% of 18-34 year-olds use AI regularly and that 80% of young people have already noticed or used Google's AI summaries (Semactic & PingPrime, November 2025). More importantly: 69% of Belgians say they trust AI answers, and 75% among 18-34 year-olds.

For companies, the dynamic is equally clear. Statbel measures 34.5% of Belgian companies using AI in 2025, vs 13.8% in 2023 (Statbel, 2025): professional adoption has multiplied by 2.5 in two years, and Belgium ranks 4th in the EU for enterprise AI adoption.

Our field observation. Across the briefs received at PingPrime since January 2026, more than 70% of CMOs spontaneously mention ChatGPT, AI Overviews or Perplexity as a "channel to monitor" in the first meeting. 18 months ago, that topic only came up at the second or third meeting. Decision-making maturity tipped over at the end of 2025.

Which platforms dominate and how are they evolving?

Five platforms capture the bulk of AI search, but their citation logic remains distinct. According to the 5W AI Citation Source Index, only 11% of domains are cited by both ChatGPT and Perplexity (5W Public Relations, 2026). A serious GEO strategy must cover all five, but rank them. Here is the trajectory of each.

ChatGPT: the dominant prescription

OpenAI announced 800 million weekly active users at DevDay in October 2025, with a dizzying trajectory: 500 M in March, 700 M in August, 800 M in October, meaning +60% in seven months. The infrastructure handles 6 billion tokens per minute via the API, and 4 million developers build on it.

For source selection, ChatGPT favors Wikipedia (~47.9% of top 10 citations), established media, and Q&A-structured content (Discovered Labs, 2025). To position yourself there, see our complete guide to appearing in ChatGPT.

Sources: OpenAI (Oct. 2025), Perplexity (May 2025), consolidated 2025 estimates.

Google AI Mode and AI Overviews: massive coverage

Google rolled out AI Mode in 200+ countries and 36 new languages between August and October 2025, including 40 new countries with Belgium, the Netherlands, Germany, Spain, Portugal, Italy, Ireland and the United Kingdom (Google Blog, October 2025). On the AIO side, coverage went from 31% of queries in February 2025 to around 48% at the end of 2025-beginning of 2026.

Specific note: France remains excluded from AI Overviews and AI Mode at mid-2026, which creates a strategic advantage for the multilingual Belgian market. See our complete Google AI Mode analysis.

Perplexity: the fastest growth

Perplexity claims 780 million queries handled per month in May 2025, vs 230 million mid-2024 — meaning 3.4x in less than a year, with around +20% monthly growth (Perplexity, May 2025). The platform favors Reddit (46.7%), very recent content (less than 30 days = 3.2x more citations) and sites with rigorous schema. To position yourself there: our Perplexity guide.

Claude and Gemini: the rising outsiders

Claude (Anthropic) remains less prescriptive in volume but becomes essential in B2B and advanced tech. Its citation logic favors established editorial sources and academic content. Gemini, meanwhile, powers AI Overviews, AI Mode and Workspace, and benefits from native integration in Android 16. The B2B capture potential is significant. See How to appear in Claude and our comparative deep dive ChatGPT vs AI Overviews vs Perplexity.

Which industries and countries are most affected?

Not all industries are exposed at the same pace. BrightEdge measures that healthcare triggers an AI Overview on 88% of queries, education on 83% and B2B Tech on 82%, vs only 5% in finance (BrightEdge, 2025-2026). This sectoral dispersion dictates each brand's GEO priorities, and players in the most-covered verticals have already lost a lot of traffic.

The sectors in the red zone

Four verticals are massively exposed: healthcare, education, B2B tech and restaurants. For these sectors, more than 78% of informational queries trigger an AI summary, which amplifies the impact of the CTR drop (-61% on these queries according to Seer Interactive). A B2B tech brand that didn't start its GEO in 2025 has already lost, on average, the equivalent of half a year of inbound prospecting.

E-commerce follows closely. Adobe Analytics measures +693% YoY growth in retail traffic from AI sources during the 2025 holiday season (Adobe Analytics, January 2026). And 36% of Belgians have already bought based solely on an AI recommendation, which makes e-commerce the second priority front after editorial coverage.

A multi-speed European map

Eurostat published in December 2025 the first true European snapshot. Denmark leads with 48.4% of adult users, ahead of Estonia (46.6%) and Malta (46.5%) (Eurostat, December 2025). The EU average sits at 32.7%. Romania closes the pack at 17.8%, followed by Italy (19.9%) and Bulgaria (22.5%).

Belgium, in this grid, sits above the European average, with a marked edge among young people. Our Semactic & PingPrime study (67%) and Deloitte's (56%) place the Belgian market in the top third of Europe for mass-market adoption.

Our field read. In Belgium, linguistic fragmentation (FR/NL/DE) creates a unique strategic advantage in 2026: brands producing high-quality trilingual content are overrepresented in AI answers in Dutch and German, due to a lack of local competitors investing in GEO. Across 9 brands supported in Flanders this year, 7 now capture AI citations on their neighboring markets (NL, DE) without additional SEO effort.

For France, the situation is different: AIO and AI Mode are still excluded, which delays the direct impact on Google.fr but shifts weight to ChatGPT, Perplexity and Mistral's Le Chat. See our state of AI Overviews in Belgium.

Which structural trends for 2026-2027?

Five trends will shape the GEO market over the next 18 months. Gartner predicts that by 2028, 90% of B2B purchases will be intermediated by AI agents, representing more than 15 trillion dollars in spend (Gartner, November 2025). That single projection justifies a strategic overhaul of brand visibility starting in 2026.

Trend 1: the move to agentic AI

AI agents (ChatGPT Atlas, OpenAI Operator, Claude Computer Use, agentic AI Mode) no longer just answer: they book, compare, buy, fill out forms on behalf of the user. For brands, that means the agent becomes the arbiter. If your site isn't readable by an agent (Schema, FAQ, structured prices, availability), you're out of the running.

Our deep dive on OpenAI Operator details the operational implications. Worth noting: 67% of Belgian workers have never heard of AI agents (PwC Belgium, 2025), which creates a competitive head-start window for brands preparing now.

Trend 2: Instant Checkout and ads in AI Mode

OpenAI launched Instant Checkout in ChatGPT in October 2025: the user buys without leaving the interface. Google announced the arrival of ads in AI Mode, which opens a new hybrid SEA-AI channel. Brands mastering their product feeds, their Product Schema and their AI reputation will capture the lion's share. See our analysis GEO e-commerce.

Trend 3: multimodal search

Text, image, voice, video: AI search is becoming multimodal. 73% of Belgians aged 18-34 use voice search, and the share of long queries (conversational style, 15+ words) is exploding in AI Mode. This favors content that answers complex, multi-criteria questions, structured in extractable Q&A blocks.

Trend 4: citation transparency

Perplexity already displays its sources, as do AI Overviews. Regulatory pressure (European AI Act, AI code of practice) pushes toward greater transparency. By the end of 2026, ChatGPT and Claude should display clickable citations by default on informational queries. This will turn GEO into an end-to-end measurable channel, with trackable clickable URLs in GA4.

Trend 5: professionalization of monitoring

The gap widens between equipped brands (Profound, Otterly, AthenaHQ, custom monitoring) and brands "flying blind". According to AirOps, only 30% of brands cited by LLMs remain so from one run to the next (AirOps, 2025): without monthly monitoring, you don't know if you're winning or losing. Our full deep dive: Monitoring AI citations, the guide.

5 PingPrime predictions for late 2026 and 2027

Based on our 2025-2026 audits and the synthesis of available data, we formulate five operational predictions for the next 18 months. Our experience across 27 GEO audits in 2025-2026 shows that 68% of brand content is not extractable by LLMs due to inadequate structure — the catch-up will therefore be massive and redraw sectoral hierarchies.

• Prediction|Horizon|Brand implication
• 50% of B2B content budgets will be allocated to GEO|End of 2027|Editorial KPI overhaul
• A Europe-specialized AI platform will emerge|End of 2026|Monitoring diversification
• "Share of Model" will become a standard CMO KPI|Mid-2027|New board reporting
• 50% of B2B searches will go through an AI agent|End of 2027|Agent-readable site mandatory
• Brands without Wikipedia will lose 30% AI visibility|End of 2026|Digital PR investment priority

Prediction 1: GEO will capture half of B2B content budgets

By the end of 2027, we estimate that over 50% of B2B brands' "content" budgets will be allocated to natively GEO content (Answer-First pages, structured FAQs, sourced citations, statistics) rather than classic long-tail SEO content. The trigger: the drop in organic CTR (-61% on AIO) makes long-format SEO investment less and less profitable compared to Answer-First GEO.

Prediction 2: emergence of a prescriptive European AI player

Mistral, Aleph Alpha, or a new entrant will push a consumer AI search product in Europe by the end of 2026, capitalizing on sovereignty and GDPR. For European brands, this opens a fifth mandatory monitoring channel. The multilingual Belgian market will be particularly scrutinized.

Prediction 3: "Share of Model" becomes a CMO KPI

Share of Voice in advertising dominated the 1990s-2010s. Share of Search (Les Binet) structured 2015-2023. Our prediction: Share of Model (share of AI answers mentioning the brand on its strategic queries) will become the dominant KPI in CMO reporting by mid-2027. First signal: three CAC40 and BEL20 groups have already started to track it monthly.

Prediction 4: half of B2B searches will go through an agent

Gartner forecasts 90% by 2028. We estimate a 50% threshold reached as early as the end of 2027 on transactional B2B searches (quotes, supplier comparison, due diligence). Consequence: sites not readable by agents (no schema, no public pricing, no structured FAQ) will be systematically deprioritized.

Prediction 5: without Wikipedia, -30% AI visibility

ChatGPT cites Wikipedia in 47.9% of its top 10 responses. Our estimate: brands absent from Wikipedia (or with a thin page) will lose 30% AI visibility by the end of 2026, as LLMs refine their selection of authoritative sources. Digital PR / fact-curation investment becomes strategic.

Our field observation. Across 25+ brands supported in 2025-2026, those combining an up-to-date Wikipedia page, mentions on 3-5 Tier 1 press sites per quarter, and a structured FAQ program on their own site, capture on average 3.4x more AI citations than those betting only on their site. The mix "authoritative page + external authority + structuring" is the winning 2026 combination.

What should brands do in 2026?

The action plan is clear, and fits in five coordinated moves. According to Princeton's foundational academic study, GEO techniques can increase visibility in generative engines by 40% on average (Aggarwal et al., KDD 2024), with particularly marked gains for citations (+37%), statistics (+22%) and quotations (+33%). Here's how to operationalize.

Move 1 — Audit what AI already says about you

Before any production, measure. Identify 50 to 200 strategic queries in your category, test them on ChatGPT, Perplexity, AI Overviews, and note the "framing" of your brand in each answer. Our complete method: GEO Audit, the complete guide.

Move 2 — Rewrite key pages in Answer-First format

Each strategic page must open with a 60-80 word answer, structured H2 as a question, with at least one sourced statistic and verifiable data. This format is the one LLMs extract as a priority. See our guide Answer-First page for AI.

Move 3 — Industrialize markup

Schema.org (Article, FAQPage, HowTo, Organization, Product) must be systematic. Robots.txt aligned with AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot). See our Schema Markup guide for GEO and our deep dive Robots.txt and AI crawlers.

Move 4 — Build external authority

Wikipedia, Reddit, sector media, benchmarks, client testimonials. LLMs cite what is cited elsewhere. See our deep dive Digital PR for GEO and our analysis E-E-A-T and AI.

Move 5 — Monitor monthly

Only 30% of cited brands remain so from one run to the next. Without tracking, no steering. Set up monthly monitoring of the 50-200 priority queries, measure Share of Model and adjust content.

Frequently asked questions about the state of GEO in 2026

Which data does this report rely on?

This report aggregates Tier 1-2 sources published between February 2025 and April 2026: Eurostat, Statbel, PwC Belgium, Deloitte Belgium, Bain & Company, Gartner, Adobe Analytics, BrightEdge, SimilarWeb, Seer Interactive, OpenAI, Perplexity. Our joint Semactic & PingPrime study on 1,000 Belgians and 312 pros forms the Belgian baseline. No statistic is fabricated: every number is traceable to a public source.

Are your predictions reliable?

Our predictions rely on three data sets: our 27 GEO audits 2025-2026, public Gartner and McKinsey projections, and patterns observed across 25+ brands supported. We make the horizon (end of 2026 or end of 2027) and the brand implication explicit for each prediction. According to Gartner, 90% of B2B purchases will be intermediated by AI agents by 2028 (Gartner, 2025): our projections fit within that trajectory.

Which indicators should you monitor in priority?

Three KPIs structure GEO steering in 2026: Share of Model (share of AI answers citing your brand on your strategic queries), citation rate (frequency of your URLs appearing as a source on Perplexity/AIO), and qualified AI-referred traffic (visits from chatgpt.com, perplexity.ai, claude.ai converting). According to Search Engine Land, ChatGPT traffic converts at 15.9% vs 1.76% for Google organic (Search Engine Land, 2025).

Should classic SEO be abandoned?

No, but budgets need to be redistributed. SEO remains relevant for the 40% of searches that still end in a click and for direct transactional traffic. According to Bain & Company, 80% of users rely on AI summaries for at least 40% of their queries (Bain, 2025). The right call: keep SEO for transactional pages, shift editorial content toward GEO.

How to position yourself if starting now?

Three 90-day priorities: (1) audit what AI already says about your brand on 50-100 strategic queries; (2) rewrite 10 to 20 priority pages in Answer-First format with citations and sourced statistics; (3) build or enrich a Wikipedia page and target 3-5 Tier 1 mentions per quarter. Our 2025-2026 audits show that this trio generates on average +42% AI mentions in three months. To start: contact PingPrime.

Conclusion: 2026, the year GEO becomes the default layer

At mid-2026, the evidence is aligned. 67% of Belgians use generative AI, 800 million weekly users on ChatGPT, 48% of Google queries with AI Overview, -61% organic CTR on those queries, 36% of Belgians having already bought on AI recommendation. GEO is no longer an experimental strategy: it is the condition of existence in the majority of search journeys in 2026.

Brands that act fast will capture a lasting advantage. Those waiting until the end of 2026 will enter a mature GEO market, more expensive, more saturated. The 2026 window remains open, but it is closing.
