How much web traffic comes from AI bots?

Cloudflare clocks 32% of total traffic as automated, with AI crawlers dominating 80% of identified bot activity — mostly training data grabs.

Why do AI crawlers ruin CDN caches?

They chase unique, diverse long-tail content inefficiently — tons of 404s, no session reuse — evicting hot human pages and spiking origin hits.

Will CDNs charge extra for AI traffic?

Likely. Echoing early search deals, expect tiered caches or 'pay per crawl' by 2026 to balance humans vs. bots.
