AI changes search behavior. Hybrid searching—mixing traditional and AI tools—dominates. Users still prefer Google’s organic search out of habit.

In the UK, ChatGPT leads AI chatbots with 80.55% market share, per Statcounter. Microsoft Copilot follows at 10.41%, while others lag. This mirrors Google’s search dominance, suggesting AI rivals face a tough climb.
