AI agent traffic surged 5.26% MoM in April, with browser-based agents Comet (48.12%) and Atlas (21.33%) dominating 70% of observed activity. Blocking rates rose to 8.2%, signaling escalating detection challenges.

In brief - AI-driven web traffic is growing rapidly, with media, ecommerce, and travel sectors bearing 98% of the volume. Organizations must enhance visibility to distinguish AI agents from human activity and mitigate unauthorized actions.

Technically - Browser-based agents like Perplexity’s Comet and OpenAI’s Atlas leverage user-agent strings, cookies, and session behaviors to mimic human patterns, complicating detection. Traffic is concentrated in product/search routes (69.57%), while federal/government (+254%) and SaaS (+41.5%) sectors show rapid growth. Behavioral signal analysis and publisher-level integration are critical for classifying agent intent and mitigating risks.
