Commenting on the fact that Google's chatbot is ranked fourth globally for referrals, Aodhan Cullen added: "Google now finds itself in the same dilemma as traditional on-premise software providers at the birth of cloud computing. Its cash cow, Search, is at risk from new AI technology, which ironically, it helped to create."
He added that reports that Apple may add AI search to Safari emphasises Google's challenge.
The Statcounter data finds that ChatGPT dominates referral market share in all G20 countries except China. DeepSeek leads with 89.3% in China.
