Summary

UC Berkeley 和华盛顿大学的一项新研究发现，到 2026 年 8 月，约 24% 的可抓取网页包含 AI 生成或 AI 编辑的文本，相比 2022 年前几乎为零大幅增长；小而低链接的网站贡献了 78.8% 的增长。

New study from UC Berkeley and Univ of Washington found that about 24% of crawlable webpages held AI-generated or AI-edited text by August 2026, up from almost none before 2022. They sampled 5.1M pages from Common Crawl snapshots spanning 2019 to 2026, in every language. A statistical model corrected for each detector's false alarms and misses, using pre-2022 pages as a near-AI-free baseline. Yearly growth nearly doubled, from 4.6 points between early 2023 and early 2025 to 8.1 points after that. Small, little-linked sites drove 78.8% of the rise, while the most central sites were least likely to have AI text.

New study from UC Berkeley and Univ of Washington found that about 24% of crawlable webpages held AI-generated or AI-edited text by August 2026, up from almost none before 2022.

They sampled 5.1M pages from Common Crawl snapshots spanning 2019 to 2026, in every language. A statistical model corrected for each detector’s false alarms and misses, using pre-2022 pages as a near-AI-free baseline.

Yearly growth nearly doubled, from 4.6 points between early 2023 and early 2025 to 8.1 points after that. Small, little-linked sites drove 78.8% of the rise, while the most central sites were least likely to have AI text.

The uneven rise of AI-generated web content

arXiv cs.AI

This arXiv paper analyzes over 5 million webpages from 2019 to 2026, finding that the share of pages with AI-generated text grew from near zero before 2022 to nearly 25% by August 2026. The rise is uneven: English-language and .com domains have higher AI prevalence than other languages or .gov/.edu domains, and AI text concentrates in the least central pages of the web graph, with estimates produced via a Bayesian hierarchical model correcting for detector error rates.
