AI search statistics 2026: how B2B buying research moved into assistants

How to read AI search statistics

Three habits keep you honest. Check the denominator: "x% use AI" means something different for consumers, knowledge workers and B2B buying committees, and most headline numbers come from software buyers specifically. Check the date: adoption curves this steep make 18-month-old figures historical artefacts - G2 measured a jump from roughly 60% to 71% in seven months. Check the incentive: vendors publish statistics that flatter their category, EntityRise included, which is why every figure below names its source and sample so you can weigh it yourself.

Adoption: who is asking assistants

51% of B2B software buyers now start their research with an AI chatbot more often than with Google (G2, The Answer Economy, survey of 1,076 B2B software buyers and decision-makers, March 2026, published April 2026).

71% of B2B software buyers rely on AI chatbots for software research, up from roughly 60% seven months earlier (G2, same survey).

86% of B2B buyers increased their use of AI chatbots for software research over the past year, and just 3% say AI chatbots have not meaningfully changed their research habits (G2, same survey).

66% of US business professionals regularly use AI specifically to research products, vendors or solutions for work (Semrush, survey of 600+ US business professionals, published 2026).

94% of business buyers report using AI during their buying process, up from 89% a year earlier (Forrester, Buyers' Journey Survey of nearly 18,000 global business buyers, reported in The State Of Business Buying, 2026, January 2026).

Provider spread for product research: ChatGPT 71%, Gemini 61%, Copilot 45%, Perplexity 18%, Claude 14% (Semrush, same survey) - buyers move between several assistants, which is why single-provider checks miss most of the picture.

Buying behaviour: what AI changes in vendor selection

69% of buyers chose a different software vendor than they originally planned, based on AI chatbot guidance (G2, March 2026).

33% - one in three - purchased from a vendor they had never heard of before it appeared in an AI answer (G2, March 2026).

92% of B2B buyers say AI has shaped their vendor shortlist, and 83% say it influenced their final vendor decision (Semrush, 2026).

41% say comparing vendor strengths and weaknesses is their top use case for AI chatbots in software research, ahead of basic product research and vendor identification (G2, March 2026).

82% of B2B software buyers sourced software recommendations from an AI chatbot in the last two years (G2, 2026 Buyer Behavior Report, survey of more than 1,000 buyers, July 2026).

Fragmentation: the same question, different AI answers

12% of cited sources match across ChatGPT, Perplexity and Google AI answers (Passionfruit, 2026; the 15,000-query sample as reported in industry coverage).

11% of domains are cited by both ChatGPT and Perplexity, in a study of 680 million citations (Averi, B2B SaaS Citation Benchmarks Report, March 2026).

More than 60% of 1,600 test queries got incorrect citation answers across eight AI search engines, with Perplexity lowest at 37% (Tow Center for Digital Journalism, Columbia University, 200 news articles tested on each engine, March 2025).

Taken together, these are the strongest published argument against single-provider checks: the engines disagree about which sources to trust, so visibility measured in one of them says little about the others. How engines choose those sources is covered in AI citations explained, and the measurement protocol that accounts for it is on the methodology page.

Business impact: what it does to pipelines

1.08% of total website traffic came from AI referrals across 13,770 domains studied - AI referral volume is still small (Conductor, 2026 AEO / GEO Benchmarks Report).

14.2% conversion rate for AI-referred visitors versus 2.8% for Google organic, roughly a 5x difference, across 312 B2B technology firms' GA4 and CRM data (Opollo, 2026 AI Search Benchmark Report).

0.5% of sessions from AI search produced 12.1% of signups for one B2B SaaS company - a 23x differential, and a single-company ceiling rather than a benchmark (Ahrefs, published June 2025).

31% better conversion from AI referrals than non-AI traffic during the 2025 holiday season, across more than a trillion visits to US retail sites (Adobe Digital Insights, January 2026).

What the pattern across these sources supports, stated conservatively: AI referrals are low in volume and high in intent, and volume-based reporting systematically undervalues the channel. The honest reading is that AI visibility is not yet a traffic story - it is a shortlist story, and the shortlist forms before any traffic exists to measure.
