Amazon Publisher Services

Leading cloud-based header bidding provider backed by Amazon's advertising ecosystem

Amazon Publisher Services (APS) is Amazon's suite of cloud-based services designed to help digital publishers optimize their advertising revenue. Operating as a subsidiary of Amazon, APS provides publishers with header bidding solutions, transparent auction technology, and direct access to Amazon's demand sources. The platform's flagship products include Transparent Ad Marketplace (TAM), a cloud-based header bidding solution, and Unified Ad Marketplace (UAM), which enables publishers to conduct unified auctions across display and video inventory. APS serves as a critical bridge between publishers and Amazon's extensive advertising ecosystem, including Amazon DSP and third-party demand sources. The platform leverages Amazon's cloud infrastructure to deliver low-latency ad decisioning and provides publishers with tools to manage complex programmatic advertising operations. APS competes in the supply-side platform and header bidding wrapper space, differentiating itself through its integration with Amazon's first-party shopping data and demand. As part of Amazon's broader advertising business, APS plays a strategic role in expanding Amazon's reach beyond its own properties into the open web. The service is particularly attractive to publishers seeking to monetize their inventory with Amazon's retail-driven advertising demand while maintaining control over their ad stack through transparent, cloud-based technology.
