ChainThink reports that, according to recent data from Similarweb published by TechCrunch on July 28, the prevalence of Google AI Overviews in search results has increased from 15% to 43% over the past year.
During the same period, monthly visits to AI Mode increased from 126 million in June 2025 to 279 million in May 2026.
Average search length continues to rise, with short keyword queries being replaced by more natural, conversational questions, and user dwell time on Google platforms has significantly increased. This shift is impacting content publishers.
Data shows that AI references have increased more than fivefold compared to a year ago, but the actual number of external link clicks generated remains limited.
After ChatGPT launched its search update on May 7, the U.S. desktop web referral rate rose from 25% in March to nearly 60% by the end of May.
