What Invalid Traffic means

Invalid traffic (IVT) refers to any ad traffic that is not generated by genuine human users with real interest. The Media Rating Council classifies IVT into two categories: General Invalid Traffic (GIVT) — easily detectable through routine methods (known bots, data center traffic, crawlers) — and Sophisticated Invalid Traffic (SIVT) — requiring advanced detection (hijacked devices, ad injection, cookie stuffing). IVT affects all advertising metrics, wastes budgets, and distorts campaign optimization. Platforms filter IVT through pre-bid and post-bid detection, and may provide credits for detected invalid traffic. The TAG (Trustworthy Accountability Group) Certified Against Fraud program provides industry certification for IVT prevention. Advertisers should monitor for IVT indicators including abnormal CTR patterns, high impression-to-conversion ratios, and traffic from unexpected geolocations.
