Rapid Tab Blurs

Detection approach

Rapid tab switching detected: multiple blur events within the first seconds of landing. Humans rarely switch tabs immediately. Rapid switching is a signature of multi-account or multi-proxy automation.

How this helps detect bots

This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

Users opening multiple search results in background tabs and clicking through them.
