Q: What actually gives bot traffic away? I want to understand it, not dodge it.

A: Good question — understanding detection helps you keep your own placements clean. Modern bot detection rarely relies on one tell. It layers signals:

— Behavioral: no mouse movement, instant clicks, perfectly uniform timing between events. Humans are messy; bots are precise.
— Environmental: headless browser markers, missing canvas or WebGL fingerprints, automation framework leftovers in the JavaScript environment.
— Network: known datacenter IP ranges, residential proxies with too many users behind one address, mismatched TLS fingerprints.
— Reputation: an IP or device that hit 200 offers this week.

The single biggest giveaway is consistency. Real users vary in screen size, scroll depth, and dwell time. Bot farms produce eerily similar sessions at scale.

For you, the takeaway is placement hygiene: pop and auto-refresh inventory attracts non-human traffic you never asked for. Audit where your impressions actually render.

Short version: bots get caught by being too consistent. Clean your sources before the detector does it for you.
