One-Third of New Websites Since ChatGPT Are AI-Generated

A third of the web's growth in two and a half years is now machine-made. The internet's baseline authenticity has degraded in real time—not as a future risk, but as fact. This reshapes SEO incentives, trust signals, and the viability of human-created content discovery. Platforms and advertisers must treat AI-spam as infrastructure they route around, not a marginal problem. The speed of this capture—from zero to 35% in 30 months—means policy and platform design cannot arrest AI-generated content. The economics of automation have already secured the territory.
