Device Spoofing at the Impression Level: How User-Agent Anomalies Impact Campaign Data
Detecting fake devices isn’t as easy as it used to be.Â
There was a time when the red flags used to be clearly visible – random clicks at odd hours or sudden traffic spikes from unfamiliar regions. Those patterns made it simple to tell when bots were at play.Â

This next-level masking of fake devices as real is known as device spoofing, and it’s quietly reshaping how ad fraud hides in today’s campaigns.Â
