Amazon Ads is a multi-billion dollar global business that delivers advertising experiences across Amazon's owned-and-operated properties (including Prime Video, Twitch, Fire TV, and Amazon.com), third-party publishers, and emerging channels like generative AI-powered shopping experiences. As one of the fastest-growing segments of Amazon, we operate at unprecedented scale across desktop, mobile, connected TV, and emerging surfaces. Within Amazon Ads, Traffic Quality Signal Engineering and Analytics is a critical pillar of advertiser trust and marketplace integrity. Our mission is to build advanced signal collection, detection, and analytics capabilities that work at petabyte scale to identify and mitigate sophisticated invalid traffic (IVT) — including non-human traffic, bot networks, agentic bot traffic, and fraudulent engagement patterns across programmatic advertising. We are on a journey to establish Amazon Ads as an industry leader in traffic quality standards and transparency. We achieve this by building client-side and network telemetry collection systems, enabling forensics detection signatures, and business metrics reporting. We process billions of ad events daily, developing novel detection techniques that balance precision and recall while operating under strict latency constraints. Our work directly protects hundreds of millions of dollars in advertiser spend annually while maintaining a seamless advertiser experience.
