One in Three New Websites Are AI-Generated
A study by researchers in the US and UK finds that roughly 35% of newly created websites are AI-generated, just three years after ChatGPT's launch. The team analyzed web snapshots in collaboration with the Internet Archive and used the Pangram AI-detection tool to classify content. The researchers report that AI-written pages tend to be steriler and more positive in tone but did not find an increase in factual inaccuracies compared with pre-AI content. The article cites Netcraft data showing about 1.5 billion websites worldwide (March 2026) and Bitkom estimates of roughly 60 million new sites per year. The research team plans to continue monitoring trends and to build a continual data pipeline with the Internet Archive.
Widespread adoption of AI to generate website content changes the supply and quality of web inventory, affecting publishers, SEO, content-detection, and measurement practices across the digital advertising ecosystem.

Study: One-Third of Post-ChatGPT Pages Show AI Authorship
A Pew Research Center study released August 20, 2026, analyzed Common Crawl data covering nearly half a billion English-language pages from the past five years and scanned them with a detection tool (Open Pangram) to estimate AI-written content. Across the full archive roughly 10% of pages showed significant signs of AI authorship or heavy AI editing; when pages published before ChatGPT’s November 2022 launch are excluded, that share rises to about 35%. Pew also examined a random July 2026 sample of 10,000 pages, which likewise found about 10% with strong AI-authorship signals. The distribution is uneven across domains—about 10% of .com pages, 4.6% of .org pages, and roughly 1% for both .edu and .gov—highlighting the growing prevalence of chatbot-assisted content on the open web.
2017 Human Text Classified as AI-Generated
A persoenlich.com editorial by Christian Beck describes how a 2017 blog post he wrote was flagged as AI-generated by detectors. He reports an initial TextGuard result of 76% AI-generated and later notes TextGuard rated the same text 61% AI while Pangram judged it 100% human. The article summarizes many LinkedIn comments showing widespread mistrust of AI text detectors, with examples such as Martin Luther King Jr.'s speech being labeled highly AI-generated and genuine AI text sometimes labeled human. The piece criticizes detector reliability, highlights how detectors favor highly structured journalistic style, and warns about commercial practices that profit from humanizing content. Beck concludes that, for now, AI text detectors are unreliable.
72% Mistake Slow Websites for AI Scams
Pantheon.io published a survey finding that 72% of consumers suspect a slow or glitchy website is an AI-driven scam. The study reports high consumer skepticism about AI-generated content—92% say AI makes it harder to verify site legitimacy and 88% want companies to do more to prove authenticity. Respondents said poor site performance and missing credibility cues drive immediate defensive behavior: 41% avoid entering personal or payment information, 39% abandon purchases, 53% are unlikely to return after one suspicious experience, and 20% switch to competitors. Pantheon executives frame reliable web platforms and performance monitoring as critical to brand protection amid scammers using generative AI and tactics that can 'poison' AI search results and LLM recommendations.
