Amazon Publisher Services Expands Signal IQ Tools
Amazon Publisher Services (APS) announced expansions to Signal IQ, its bidstream testing tool, at its annual summit. The update broadens Signal IQ’s scope beyond identity signals to include bidstream fields such as global placement IDs (GPIDs), transaction IDs and video classification parameters, and adds a signal coverage report benchmarking publishers against peers. APS said it will bring expanded signal reporting into Signal IQ’s A/B testing framework later this summer to estimate projected revenue lift. APS also unveiled AI-powered features — including a Publisher Supply AI assistant (open beta later this summer) and monitoring agents — plus outcome-based planning updates: a Mobile SDK bridge for third‑party bidders, Shopping Insights expansion to web and mobile inventory, and audience-matching support for consideration objectives in the Amazon Publisher Cloud clean room.
Product and technical updates from a major platform (Amazon/APS) that improve publishers' ability to measure which bidstream signals drive DSP demand, introduce AI-assisted revenue workflows, and expand commerce-driven inventory targeting — all materially relevant to publisher monetization and programmatic buying.

Amazon Unveils AI Tools: Campaign Manager & Ads Agent
Amazon has announced AI-powered tools Campaign Manager and Ads Agent to expand its Ad Tech portfolio. Campaign Manager will unify the Ads Console and Amazon DSP into a single platform, while Ads Agent operates within the Amazon Marketing Cloud to convert questions into actionable insights. The tools are now available to advertisers in Germany, with Prime Video Ads already expanding to 16 countries and reaching about 315 million customers per month worldwide. The article notes Netflix and Spotify ad inventories will be offered via the Amazon DSP in Germany, reinforcing Amazon’s growing control over its ad ecosystem. Cyrus Zaboli, Head of Ad Tech Germany at Amazon Ads, calls the move a milestone that will streamline cross-channel campaign management and accelerate AI-powered purchasing across the funnel. The piece also mentions ongoing industry discussions around AI agents on platforms.
Amazon's APS Prebid Adapter Enters Open Beta
Microsoft Advertising will stop paying to cache Prebid video creative for Google Ad Manager (GAM) auctions, effective April 30, after previously delaying a January 31 deadline. Publishers that route Prebid video through GAM risk VAST errors (no video served) because an intermediary host for the creative will no longer be provided as a free service. Microsoft and earlier corporate owners (AppNexus, Xandr) historically absorbed those storage costs; Microsoft will make caching part of its paid offering. Industry sources estimate Microsoft’s cache has covered more than 60% of Prebid-to-GAM video impressions. Workarounds include paid caching from SSPs/exchanges (e.g., Magnite, PubMatic, Mediavine, JW Player) or Prebid’s Local Cache using a BLOB-based approach, but those options require publisher implementation changes and may reduce AdX revenue materially. Estimated caching costs cited range from $50k–$250k/month today and could rise as adoption grows.
