4. Biometric & Behavioral Interactions
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.
