MarTechCharts regularly highlights data of interest to marketers and marketing operations professionals.

Traditional search continues to dominate user activity, according to a new report, with AI and ecommerce search tools running behind.
The “State of Search Q2 2025: Behaviors, Trends, and Clicks Across the US & Europe” (registration required) from Datos and SparkToro found activity in AI tools among U.S. users shows a consistent rise in event share, growing from 0.24% in April 2024 to 0.64% by April 2025. While the numbers remain relatively small, the growth rate is significant, nearly tripling in share over the year.
Ecommerce event share has remained relatively stable overall, with fluctuations month-to-month, peaking at 4.07% in July 2024 and dipping to 2.48% in February 2025.

The report also found traditional search similarly dominates in Europe, but AI tools show more aggressive growth than in the U.S., rising from 0.26% in April 2024 to 0.78% by April 2025. ]
The steeper European growth curve is consistent with the Q1 report from Datos, which showed the E.U. and U.K. outpacing the US in AI adoption by Q1’s end.
Ecommerce remains stable in Europe, hovering between 1.75% and 2.23% over the past year, with a slight upward tilt in Q2 2025.
