Google AI Overviews Cut Website Clicks by 58%
New research from Ahrefs, reported via Business Wire and MarTech Series on May 19, 2026, found that Google’s AI Overviews have reduced average click-through rates to top-ranking pages by 58% (compared with a 34.5% reduction eight months earlier). The study analyzed Google Search Console data for 300,000 keywords, comparing December 2023 (pre-AI Overviews) to December 2025. The impact extends across the first SERP page—pages in position two lost roughly half their clicks and even position ten saw drops near 20%. Ahrefs warns this shift accelerates “zero-click” search behavior and is monitoring SERP features’ effects on publisher traffic and visibility.
Research quantifies a large decline in organic click-through rates driven by a major platform feature (Google AI Overviews), signalling material traffic and discovery shifts for publishers, SEO practices, measurement, and ad monetization.

AI Overviews Slash Google CTR, Ahrefs Finds
Ahrefs analyzed Google search data from December 2025, using 300,000 keywords (150k with AI Overviews and 150k without) to compare click-through rates (CTR). The study shows AI Overviews are correlated with a substantial drop in organic CTR, averaging a 58% decrease in clicks for keywords that trigger AI Overviews. In December 2023, the average CTR for position zero without AI Overviews was 0.076; by December 2025 it was 0.039. For keywords that had an AI Overview in 2025, CTR stood at 0.016 in December 2025, versus 0.073 in December 2023 for those without AI Overviews. Ryan Law (Director of Content Marketing at Ahrefs) highlighted the trend, and Barry Schwartz reacted with 'Ouch' on X. The article discusses implications for publishers, including a potential shift toward zero-click search and ongoing debates about compensation for content processing by AI and search engines.
Google AI Overviews Reduce Search Clicks, Shift SEO KPIs
Research cited in the article shows Google’s AI-generated Overviews are associated with lower click-through rates to traditional search results, challenging conventional SEO measurement. Pew Research Center’s March 2025 analysis found AI Overviews appeared in about 18% of searches; when present, roughly 8% of queries led to a click on a traditional result and about 1% led to a click within the AI summary. The piece argues SEO teams should separate visibility in AI answers from audience acquisition and measure visibility, engagement and business value distinctly. Organizations are advised to adopt governance, clearer ownership, structured content, and new measurement approaches to connect AI-mediated search exposure to commercial outcomes.
Google AI Overviews Slash Organic Clicks in Germany
A Sistrix analysis estimates Google’s AI-generated “AI Overviews” are costing German websites more than 250 million clicks per month. Sistrix finds AI Overviews appear for about 20% of queries in Germany and that the first-result click-through rate falls from ~27% to ~11% when an AI Overview is shown (a ~60% drop). The traffic declines hit health and family sites particularly hard; Wikipedia alone is estimated to have lost ~31.6 million clicks. Publishers and organisations including ADAC, NDR and Wikimedia Deutschland report substantial organic-traffic losses and worry about weaker source attribution, editorial participation, and measurement challenges. Google questioned methodological gaps in the Sistrix study and gave limited comment on broader rollout plans. The article highlights shifts in user behaviour (mobile AI Mode/“KI‑Modus”) that may keep users in Google’s ecosystem instead of clicking through to external sites.
