Auto-published 2,300 AI articles—Google cut 90% traffic
The author ran an automated content pipeline for a Spanish-focused site that auto-published about 2,300 AI-generated articles over sixteen months. Google Search Console data showed monthly clicks peaked at 695 in September 2025 and fell to 69 in June 2026 (a ~90% drop). In a 90-day window 1,567 pages received impressions but only 147 pages (~6%) got a single click. The author concludes volume and thin, machine-written pages harmed domain performance, recommends human review before publishing, and abandoned the auto-publish machine in favor of hand-written, curated content. Publication date: 2026-07-16.
Practical case study showing the SEO risks of large-scale auto-published AI content and the importance of human review; relevant to publishers and marketers but not an industry-wide platform policy change.

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.
Three-week AI coding tools blog — real traffic data
An author (The Dev Brief) published a three-week case study about launching a content site focused on AI coding tools. After 35 articles the site recorded 1,660 Google impressions but only 5 clicks (0.3% CTR) with an average SERP position of 34. Instant indexing via Google Search Console increased indexed pages from 4 to 30+ within 48 hours. The author reports Reddit engagement (157 karma) but limited referral clicks and concludes backlinks, not more articles, are required to improve search position.
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.
