Definition & Explanation

Geo masking is a fraud tactic in which IP addresses or location data are spoofed to make traffic appear as though it originates from premium, high-value geographies. Fraudsters use VPNs, proxy servers, and GPS manipulation to disguise low-quality traffic from cheaper regions and sell it at premium CPMs. This undermines geo-targeted campaigns by delivering ads to the wrong audience, leading to wasted ad spend and distorted performance metrics.
