ChatGPT core update increases German publishers' visibility
SEO firm Sistrix identified what it calls the first documented "core" update in ChatGPT following OpenAI's rollout of GPT-5.5 on 22 May 2026. Sistrix measured a 47% shift in the domain (citation) distribution for German-language ChatGPT answers within 48 hours of the rollout — a change far above the usual 1–2% range — by comparing four-day periods before and after the event and analysing 800,000 responses. German mainstream media, TV and streaming platforms, specialized tools and Reddit gained visibility, while international aggregators (Indeed, Tripadvisor, Expedia) and global platforms (YouTube, Google, Wikipedia) saw double-digit declines. Sistrix cautions the cause may be the model switch or concurrent changes to retrieval/prompt layers.
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.
