Study Finds Google's AI Overviews Lower CTR
A Pew Research Center study analyzes browsing data from 900 American adults in March 2025 to assess Google's AI Overviews in search results. The study finds that AI-generated summaries are visible in a majority of sessions and that roughly 18% of queries produce an AI Overview. For users who see an AI Overview, click-through rates to regular results drop sharply: 8% CTR versus 15% for those who do not see an Overview. Interaction with sources listed in AI Summaries also remains low, with a 1% CTR on source links. The research suggests that AI Overviews steer users toward additional Google searches or other sites, and that sessions tend to end sooner after exposure. The piece notes sources such as Wikipedia and .gov domains in AI Overviews and highlights implications for publishers’ traffic and monetization. A related antitrust complaint against Google over AI Overviews is mentioned.

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 announces AI updates to restore website traffic
Google has announced five changes to its generative-AI search features intended to steer more referral traffic back to publishers after AI-driven summaries reduced click-through rates. An Ahrefs analysis (Feb 2026) found average search traffic fell by about 58% after Google introduced its AI mode and “AI Overviews.” Google's updates include a deeper-explore section with curated links to source articles, a desktop inline-link context that shows site name and page title on hover, highlighting of links from active news subscriptions, previews of opinions from forums and social media, and expanded review/merchant links for product searches. The moves follow publisher pushback — including a Penske Media antitrust filing and complaints to the European Commission — and echo independent research showing far lower click rates when AI summaries appear. Google frames the changes as making AI summaries a starting point that more easily routes users to original sources.
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.
