4. Biometric & Behavioral Interactions
Fast Reading Scraper
Detection approach
Impossible reading speed words/sec across the page. Humans read at 2-5 words/sec. A bot may scrape the entire DOM instantly without scrolling or pausing.
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
Quick bounces where user lands on the page, doesn't find what they need, and exits in under 1s.
