Research on Google AI Overviews shows significant variance in prevalence depending on the methodology and dataset. Semrush reports that AI Overviews appeared in 88% of desktop searches within a specific commercial panel by August 2026, up from 45.75% in September 2025. Conversely, seoClarity recorded a 30% share in September 2025, while Pew Research found AI summaries in 18% of 68,879 queries analyzed in March 2025.
The frequency of AI-generated responses correlates with query length and type. Pew Research noted that AI summaries appeared in 8% of one-to-two-word queries, rising to 53% for queries of ten words or more. Data from SE Ranking indicates that informational queries are more likely to trigger AI responses, while local queries see them in only 0.01% of cases according to seoClarity.
Regarding Yandex, the company has not disclosed the overall share of Alice AI responses. A report from April 2026 stated that updated models increased the frequency of quick answers by 1.5 times, though the baseline was not specified. Research by Ashmanov and Partners indicates that the share of sites outside the top 10 organic results appearing in Alice AI responses dropped from 40% to 10% between August 2025 and January 2026.
The impact of AI summaries on traffic remains a subject of study. Pew Research found that users clicked on standard search links in 15% of visits when no AI summary was present, compared to 8% when one was displayed. Wikipedia reported a 5% decline in traffic following the launch of AI Overviews, while other reports suggest potential losses of up to 30% for informational websites.
