AI Overviews spread across most major-brand searches in new tracking
Tracking from Ahrefs suggests Google AI Overviews expanded sharply on U.S. results for major-brand searches, appearing on 5 of 98 usable queries on July 1 and 63 of 100 by September 30. Broader vendor samples found different prevalence rates, underscoring measurement differences. The evidence does not establish how often brands were cited or whether clicks changed.
Why it matters: Marketers can no longer assume that even navigational or brand-name searches lead directly to traditional organic results. They should monitor whether AI Overviews cite the brand, which external sources appear, how messaging is represented, and whether branded-search traffic and measurement patterns change. The exact prevalence is uncertain because the studies use different samples and do not establish click impact,|
