AdShield by SHIELD is designed to protect ad spend, optimize customer acquisition costs, and prevent skewed analytics. It blocks invalid traffic (IVT) that damages marketing campaigns, whether paid or organic. IVT generates poor leads, reduces ad campaign visibility, and skews marketing metrics. AdShield uses unsupervised machine learning to combine network and device intelligence to thwart invalid traffic and boost return on ad spend in real time. It helps businesses stop fraud, build trust, and drive growth by filtering out fraudsters and investing in trusted users at every point of the user journey. AdShield is built for marketers to boost conversion rates, safeguard data and analytics, and maximize campaign revenue. It provides real-time attack pattern syncing and a continuously updating fraud library through SHIELD’s Global Intelligence Network, enabling businesses to scale with confidence.
