+66.0%
growth in AI-referred traffic across Semrush's 2025 study window.
More than 50,000 websites, 17 industries, worldwide desktop and mobile traffic, January–December 2025.

AI search statistics for 2026.
AI search is moving fast enough that the denominator matters more than the headline. Every growth rate below stays beside its traffic share, study window, or sample. A referral spike caused by a product-interface change is labeled as an event, not a permanent baseline.

01Traffic reality
AI traffic is growing quickly from a very small base.
Semrush analyzed more than 50,000 websites across 17 industries during 2025. The honest headline needs both numbers: AI grew rapidly, while organic search still delivered vastly more visits.
0.14%
of total website traffic came from AI sources in the same study.
High growth rate, small denominator. Both facts belong in the same sentence.
16.04%
of total traffic came from organic search, which grew 2.38% during the year.
>1T
organic visits appeared across the sites in Semrush's study.

industries recorded AI-traffic growth.
38.2M
monthly Google AI Mode visits Semrush reported by December 2025, up from about 1,600 in January.
Despite the increase, Google AI Mode accounted for about 0.01% of traffic in the study.
02Google behavior
When an AI summary appears, users click the traditional results less often.
Pew observed real browsing behavior rather than asking people what they remembered doing. The study covered 68,879 Google searches made in March 2025 by 900 consenting US adults.
18%
of observed Google searches produced an AI summary.
8% vs 15%
traditional-result click rates when an AI summary appeared versus when one did not.
An observed association in the search sessions, not proof that every summary causes the same change.
1%
of visits to pages with an AI summary included a click on a source cited inside the summary.
26% vs 16%
share of sessions that ended after the results page with an AI summary versus without one.
88%
of AI summaries cited three or more sources.
03Queries & platforms
Long questions trigger summaries, while platform design controls whether citations send traffic.
Pew found that query shape strongly predicted AI-summary appearance. Similarweb's platform data shows how quickly audience and referral behavior can shift when an assistant changes its interface.
53%
of observed Google searches with ten or more words produced an AI summary, compared with 8% of one- or two-word searches.
60%
of searches beginning with a question word produced an AI summary.

week-over-week jump in tracked ChatGPT referral traffic after clickable brand links changed on May 7, 2026.
A platform-interface event, not a stable annual growth rate. Homepage referrals rose 354.7% in that observed week.
49%
of US adults used AI chatbots in Pew's 2026 survey, up from 33% in 2024.
Nationally representative survey of 5,119 US adults, fielded February 17–23, 2026.
What this data does not prove
Growth rate without traffic share is misleading. AI referrals grew 66% in Semrush's study while accounting for 0.14% of total traffic. Organic search still represented 16.04%.
A citation is not the same as a click. Pew found that 88% of AI summaries cited at least three sources, but source links inside the summaries received clicks in only 1% of visits to those pages.
Platform metrics can change overnight. Similarweb's May 2026 referral jump followed a clickable-link interface change. Treat platform-specific referral rates as dated observations, not permanent rules.
04FAQ
Common questions
How much website traffic comes from AI search in 2026?
In Semrush's 50,000-plus-site study, AI sources accounted for 0.14% of total traffic even after growing 66.02% during 2025. Organic search accounted for 16.04%.
Do Google AI summaries reduce clicks to websites?
Pew observed a 15% traditional-result click rate when no AI summary appeared and an 8% rate when one did. Only 1% of visits to AI-summary pages included a click on a source cited inside the summary.
What kind of searches trigger AI summaries?
Longer and question-shaped searches were much more likely to trigger them in Pew's study. Fifty-three percent of searches with at least ten words and 60% of searches beginning with a question word produced a summary.
Is generative engine optimization replacing SEO?
No. AI visibility adds a citation surface, while organic search still sends far more traffic. The practical overlap is strong: publish verifiable facts, answer specific questions, maintain crawlable pages, use clear structure, and earn real mentions.
