GEO Statistics 2025: AI Search Data That Will Change How You Look at Marketing

Data says more than persuasion. Here are the key numbers shaping GEO in 2025 — with source citations, so you can verify, expand, and argue with them.

The growth of AI search

+527% — that's how much website traffic coming from AI sources grew year over year in 2025 (Previsible, 2025 State of AI Discovery Report, analysis of 1.96 million LLM sessions).

This number isn't about switching from Google to AI. It's about expansion — people are using AI as a new entry point into the information space, in parallel with their existing behavior.

83% of AI search users don't click through to any link — they take the answer directly from the AI (user behavior study, Semrush, 2025). This number is critical: the traditional click-through model is breaking down for an ever-growing share of searches.

B2B buying behavior

94% of B2B buyers actively use AI tools during the research phase of purchasing (6sense, B2B Buyer Experience Report 2025, survey of 4,000+ buyers).

51% of software buyers start their product research in AI chatbots, not on Google or LinkedIn (G2, The Answer Economy, April 2026, survey of 1,076 B2B decision makers). Up from 29% in April 2025 — an extraordinary pace of adoption.

AI isn't a single tool — it's a new layer across the entire research process.

Conversion rates

These are probably the most important numbers for making the business case:

4.4× — that's how much better visitors coming from AI sources convert compared with Google organic (Semrush, June 2025).

The specific numbers: the average conversion rate of AI-referred visitors is 14.2% vs. 2.8% for Google organic (Opollo, 2026 AI Search Benchmark Report, analysis of 312 B2B technology companies). The explanation is logical: a customer who arrives at your website after AI explicitly recommended you has far higher intent and trust. The AI pre-selected them for you.

The average order value of AI-referred visitors is 23% higher than Google organic (Klaviyo e-commerce data, 2025). This trend holds especially for B2B and premium segments.

The GEO market and adoption

$886 million — the estimated size of the GEO market in 2024, projected to reach $7.3 billion in 2031 at a 34% CAGR (Valuates Reports, 2025).

94% of enterprise CMOs plan to increase investment in AEO/GEO in 2026 (Conductor, State of AEO/GEO Report, January 2026, survey of 250+ senior digital executives). This interest has yet to translate into implementation — an opportunity for companies that start now.

What AI cites

32.5% of all AI citations in answers to general queries come from articles in comparison or overview formats (listicles). That's the highest share of any content format (BrightEdge AI Content Study, 2025).

+32% — that's how much a piece of content's citability increases when it contains concrete statistics with source citations (Georgia Tech / Princeton / IIT Delhi, 2024). This is one of the best-documented GEO findings.

Content with a clearly identified author is cited 41% more than anonymous content. E-E-A-T signals (author-attributed content with demonstrated expertise) are a key factor in source selection (Semrush AI Content Report, 2025).

The speed of the shift

7× — that's how many more queries B2B buyers put to AI tools compared with two years ago (McKinsey Digital, 2025). This growth is steeper than the rise of mobile search in 2010–2014.

Average age of an AI user for professional research: 34. This is the age group that will form the decision-making layer of companies for the next 20 years — their habits are setting the standard (Pew Research, 2025).

Czech Republic

Data specific to the Czech Republic is still sparse, but global trends tend to arrive with a 6–18 month lag. Companies that start working on their GEO visibility now will have a head start by the time AI search reaches the same share in the Czech Republic as in English-speaking markets.

Estimated share of AI-assisted B2B purchase decisions in the Czech Republic as of late 2025: approximately 45–55% (extrapolated from EU data, Digital Economy and Society Index 2025).

Summary for decision-making

If you should remember just five numbers:

1. +527% — growth in AI-referred traffic (Previsible 2025)
2. 4.4× — higher conversion rate for AI vs. Google organic (Semrush 2025)
3. 94% — B2B buyers using AI in purchasing (6sense 2025)
4. 51% — software buyers starting research in AI chatbots (G2 2026)
5. 34% — GEO market CAGR, projected at $7.3B by 2031 (Valuates Reports 2025)

The data is clear. The market is moving fast. The question isn't whether, but when — and how prepared you'll be.

Frequently asked questions

How fast is AI search growing? Website visits from AI sources grew 527% year over year (Previsible, 2025, analysis of 1.96 million LLM sessions). Gartner predicts a 25% decline in traditional search volume by 2026.

How many B2B buyers use AI? 94% of B2B buyers use LLM tools during the purchase process (6sense, 2025), and 51% of software buyers start their research in AI chatbots more often than on Google (G2, 2026).

Does AI traffic convert better than organic? Yes — visitors from AI search convert 4.4× better than those from organic Google (Semrush, 2025), because they arrive later in the decision-making process.

Where does the Czech Republic stand? In the early phase — generative search holds a single-digit percentage share in the Czech Republic, but Czech data already exists (drops in e-commerce organic traffic after the rollout of AI Overviews). For companies, that means a first-mover advantage: most competitors aren't addressing GEO yet.
