What happened
A Pew Research study analyzing ~500,000 English-language web pages from Common Crawl found that 35% of pages published after ChatGPT's November 2022 launch show significant signs of AI authorship or heavy editing, versus ~10% in a random sample that includes older pages. .com domains showed AI authorship at roughly 10x the rate of other domains. The findings align with Cloudflare's recent report that bot web traffic has overtaken human traffic.
Why it matters
If you publish or scrape web content, assume a large and growing fraction of the English-language web is AI-generated—especially .com pages—which affects SEO strategy, training data quality, content trust signals, and any pipeline that ingests or ranks web content. For builders using web data for AI training or RAG, this signals accelerating contamination of public corpora.
Discussion angle
What does 35% AI-authored web content mean for anyone building crawlers, search, or RAG pipelines—how do you detect and handle synthetic content in your training or retrieval data?
