AI Overviews have significantly impacted organic search click-through rates (CTR) since their introduction. By December 2025, the presence of AI Overviews correlated with a 58% decline in CTR for top-ranking pages. In December 2023, the average CTR for informational keywords at position one was 0.076, which dropped to 0.039 by December 2025. For keywords with AI Overviews, the CTR fell from 0.073 to 0.016 in the same period. This decline suggests that for every 100 clicks a top-ranking page could historically earn, Google now retains 58 clicks. The analysis involved 300,000 keywords, half with AI Overviews and half without, using data from Google Search Console to calculate monthly average CTRs. The study found that other SERP features like Local Packs and Featured Snippets have historically contributed to decreasing CTRs, leading to an increase in zero-click searches. AI Overviews amplify this trend, negatively affecting CTR across lower-ranking positions as well, though the impact is less severe than for position one. For instance, position two sees a 50.8% drop, while position ten experiences a 19.4% decline. Research from various sources, including Seer Interactive and Kevin Indig, supports these findings, showing that organic CTRs are down significantly, with some reports indicating reductions as high as 90%. The data underscores a shift in search behavior, where users can often find answers without clicking through to websites, making the landscape increasingly challenging for content creators and marketers.
