AI referrals are still under 1% of website traffic, but they grew 16x in two years

SE Ranking analysed aggregated Google Analytics data from 101,574 sites across 250 countries (January 2025 to April 2026) and found AI platforms driving 0.32% of all website traffic. That compares with 0.24% in 2025 and 0.02% in 2024 — a 16-fold rise in two years.

Other panels measuring the same thing disagree widely: Contentsquare recorded 0.2% across 6,500 sites (Q4 2025), Ahrefs 0.28% across 74,752 sites (March 2026), and Conductor 1.08% across 1,215 enterprise domains (May to September 2025). The spread is 5.4x, driven by sample composition and time window rather than error.

In Conductor’s enterprise panel, information technology recorded the highest AI referral share of any sector at 2.80%; communication services was lowest at 0.25%.

For teams building AI and developer tools or cloud services, this is one of the densest categories for AI referrals today — which also means the competition to be cited has already started.

Keep the scale in view: organic search still accounted for 42.75% of website traffic in 2026, with Google sending 134x more visits than AI platforms. That ratio was roughly 300x in early 2025 and has more than halved in 18 months, but AI referrals are not replacing organic search any time soon.

What matters is placement rather than volume: AI referrals occur early in the decision process, after the user has already asked one round of questions and narrowed the field.
