Amazon Publisher Services today announced six new capabilities at its annual APS Summit, touching nearly every layer of publisher monetization: signal measurement, mobile demand, AI-assisted analytics, shopping-intent deals, interactive video, and mid-funnel campaign planning.

The announcements, published today by Scott Siegler, Director of Amazon Publisher Services, cover the period from May 28 through summer 2026, with some features available immediately and others scheduled for the coming months. Together they represent the broadest single-event product release the division has made publicly available, spanning web, mobile app, and streaming TV inventory.

Signal IQ reaches the full bidstream

Signal IQ has been one of APS's most closely watched tools since its introduction. Originally designed to help publishers measure the revenue impact of specific audience identifiers, the product is now expanding to cover the full range of OpenRTB signals that publishers pass in their ad requests.

According to Amazon Publisher Services, the expansion means publishers can now measure how bidders value signals such as site category, video parameters, Global Placement ID (GPID), and Transaction ID. Those are technical fields embedded in every programmatic bid request; their presence or absence can influence whether a buyer participates in an auction and at what price. The Signal IQ methodology had already delivered measurable revenue lift for participating publishers using a narrower set of identifier signals, and the same A/B testing framework now applies to a wider class of data.

The rollout happens in two distinct phases. The first is available today: a new signal coverage report that shows the rate at which publishers are passing each key signal, benchmarked against peers, and identifies gaps where improved coverage could increase revenue. The second phase arrives this summer, when those signals will run through Signal IQ's A/B testing framework to project revenue lift in dollar terms - giving publishers a concrete financial figure tied to each signal investment.

Why does this matter to the marketing community? Publishers have historically had limited visibility into which technical fields in their bid requests actually affect demand. The programmatic ecosystem sends billions of requests daily, and small variations in signal completeness can translate into meaningful CPM differences at scale. PPC Land covered the original Signal IQ launch in June 2024, when Amazon positioned it partly as a response to the deprecation of third-party cookies - a tool that could help publishers demonstrate the value of their own first-party and contextual signals. The expansion to the full OpenRTB spec is a natural extension of that logic: if signal quality drives revenue, then measuring all signals - not just identity tokens - gives publishers the most complete picture.

The Transaction ID field being added to Signal IQ carries additional significance. PPC Land reported in August 2025 that the IAB Tech Lab declared modifications to transaction ID handling in Prebid.org as a material violation of the OpenRTB specification. Publishers are therefore operating in an environment where the interpretation and transmission of transaction identifiers is actively contested. Amazon's decision to include Transaction ID in Signal IQ's measurement scope puts a revenue number directly on that debate for individual publishers.

Mobile SDK bridge opens app inventory to more bidders

Mobile app publishers typically integrate multiple bidder SDKs to access the widest possible pool of demand. The problem is structural: those SDKs operate independently, which limits each bidder's visibility into the auction and makes it harder for all demand sources to compete on equal terms.

The new Mobile SDK bridge announced today addresses this by enabling third-party bidders to connect with rich ad formats and compete for app inventory with on-device auction transparency, signals, and rendering capabilities. InMobi is named as one example of a third-party bidder that can now participate through the bridge.

According to Amazon Publisher Services, the bridge gives publishers access to more than 1,000 advertisers and 28 additional bidders without any additional integration work on the publisher's side. That last point is operationally significant. Integration fatigue is a real constraint for app developers, particularly smaller studios that lack dedicated ad operations teams. Gaining access to 28 new bidders through an existing SDK rather than through separate technical implementations is a meaningful reduction in engineering overhead.

The broader competitive context here is the ongoing effort by supply-side infrastructure providers to make mobile app inventory behave more like web inventory in terms of auction transparency. Amazon's Prebid adapter, launched in open beta in January 2026, represented a similar move on the web side - enabling publishers to connect APS demand through existing Prebid.js implementations. The Mobile SDK bridge extends that philosophy into app environments where Prebid has less penetration.

Publisher Supply AI enters open beta this summer

The third major announcement is Publisher Supply AI (PSAI), a conversational AI assistant built into the APS dashboard. According to Amazon Publisher Services, PSAI is designed to solve a specific problem publishers describe repeatedly: the gap between having access to large volumes of performance data and knowing what to do with it.

PSAI launches in open beta this summer. It analyzes bid signals and performance logs from a publisher's account without requiring manual report downloads. Publishers can ask questions in plain language and receive specific insights. The system integrates with APS documentation, which means setup and configuration guidance is accessible through the same interface.

What distinguishes PSAI from a standard reporting dashboard is its AI agent layer. Amazon is rolling out proactive monitoring that can surface automated alerts and recommendations without waiting for a publisher to ask. The assistant, in other words, is designed to be reactive to queries and proactive about flagging anomalies or opportunities.

For ad operations professionals, this has practical implications. Header bidding dashboards have grown complex as publishers manage more demand sources, more signal types, and more deal structures simultaneously. The idea that an AI assistant can triage performance issues or identify configuration errors through natural language interaction - rather than through custom SQL queries or manual report exports - reflects where AI tooling is heading across adtech more broadly.

Shopping Insights deals extend to web and mobile

Shopping Insights deals have been available to streaming TV publishers, pairing their inventory with Amazon's shopping, browsing, and streaming signals so that advertisers can find and activate audiences directly in Amazon DSP. The expansion announced today brings those deals to web and mobile publishers for the first time.

According to Amazon Publisher Services, web and mobile publishers can now create curated deal packages across formats for audiences defined by category - beauty, furniture, and electronics shoppers are cited as examples - with no additional setup required. The deal packages are activated through Amazon DSP, where advertisers can reach those audiences using Amazon's first-party signal stack.

Amazon's shopping signals have become a central element of its advertising proposition. The company's advertising revenue reached $21.3 billion in Q4 2025, and the Shopping Insights expansion indicates Amazon is now deploying that commercial data advantage as a tool for attracting publisher inventory partnerships - not just for its own media properties.

For web and mobile publishers, the practical question is whether the Shopping Insights audience packages translate into meaningfully higher CPMs than standard programmatic deals. The answer will depend on category overlap between a publisher's audience and Amazon's shopper data, which varies widely by vertical. A technology news site may see limited lift from furniture shopper targeting; a home decor publication may see considerably more.

Interactive Video Ads expand beyond Fire TV and Fire OS

Interactive Video Ads - which allow viewers to add products to cart or make a purchase directly from an ad without leaving the content or using a QR code - are now available in open beta for mobile apps and connected TV environments beyond Fire TV and Fire OS.

According to Amazon Publisher Services, the ad experience allows customers to act with a tap of a screen or remote, then return seamlessly to their content. No secondary device is required. This matters because the frictionless path from ad exposure to purchase action has been one of the central engineering challenges in commerce-enabled video advertising.

The expansion beyond Amazon's own device ecosystem is the key development here. Fire TV and Fire OS are Amazon-controlled environments; extending interactive and shoppable ad experiences to third-party mobile apps and CTV platforms requires publishers on those surfaces to support the relevant ad serving and rendering infrastructure. Open beta status signals that Amazon is testing interoperability across a broader range of inventory before a full rollout.

PPC Land reported in June 2025 on the Amazon-Roku partnership that created the largest authenticated CTV footprint for advertisers, covering an estimated 80 million U.S. households. The Interactive Video Ads expansion can be read as a complement to that demand-side strategy: as Amazon brings more CTV supply into its ecosystem, equipping that supply with commerce-enabled ad formats increases the value proposition for advertisers spending through Amazon DSP.

Amazon Publisher Cloud adds consideration objectives

The sixth announcement concerns Amazon Publisher Cloud (APC), the clean room environment that enables publishers to create deals optimized for specific advertiser outcomes. The product became generally available for streaming TV and web publishers in the United States and Canada in June 2024, as PPC Land covered at the time.

Beginning in June 2026, APC will support consideration objectives in addition to its existing awareness objectives. The new consideration outcomes are Branded Searches and Detail Page Views - both mid-funnel metrics that indicate a consumer is actively researching a product rather than simply having been exposed to it.

According to Amazon Publisher Services, recommendations for these deals are generated by a machine learning model operating inside a privacy-safe clean room environment. The model helps publishers understand which of their signals are most likely to drive consideration outcomes across advertiser categories, including both brands that sell on Amazon and those that do not - financial services and automotive advertisers are cited specifically.

That last detail matters. A persistent concern among publishers considering APC deals has been whether the product primarily benefits direct Amazon sellers who care about purchase-proximate outcomes. The explicit inclusion of non-endemic advertisers in the consideration objective framework signals a broader ambition: to make APC's signal-matching infrastructure relevant to brand advertisers whose conversion cycles are longer and whose path to purchase does not run through Amazon.com.

PPC Land's earlier coverage of Amazon Publisher Cloud's launch in October 2023 noted that the original product focused on enabling publishers to combine their first-party data with advertiser insights in a privacy-preserving environment. The addition of mid-funnel objectives extends that original architecture to a wider set of campaign types.

Context for the publisher ecosystem

The six announcements taken together reflect a consistent strategic orientation. Amazon is moving to make its first-party signal infrastructure available at more touchpoints in the publisher supply chain - not just at the point of ad serving, but in measurement (Signal IQ), analytics (PSAI), deal creation (Shopping Insights, APC), and ad format capability (Interactive Video Ads, Mobile SDK bridge).

For marketing professionals watching the programmatic landscape, the APS Summit announcements arrive at a moment of structural flux. AWS launched RTB Fabric in October 2025, providing single-digit millisecond latency infrastructure for real-time bidding workloads at a cost basis 80 percent below alternatives - a development that strengthens the broader Amazon adtech stack that APS operates within.

The combination of a conversational AI layer for publisher analytics, expanded signal measurement across the full OpenRTB spec, and commerce-enabled ad formats for mobile and CTV positions APS as an increasingly integrated platform rather than a collection of discrete tools. Whether that integration is welcomed by publishers will depend partly on their appetite for deepening their reliance on Amazon infrastructure across multiple functions simultaneously.

Timeline

Summary

Who: Amazon Publisher Services (APS), the Amazon Ads division that provides cloud-based monetization infrastructure for digital publishers across web, mobile app, and streaming TV.

What: Six new product capabilities announced at the annual APS Summit: an expansion of Signal IQ to cover the full range of OpenRTB bidstream signals; a new Mobile SDK bridge enabling 28 additional bidders and more than 1,000 advertisers to compete for app inventory; a conversational AI assistant called Publisher Supply AI (PSAI) launching in open beta this summer; an extension of Shopping Insights deals from streaming TV to web and mobile publishers; Interactive Video Ads expanding in open beta to mobile and CTV environments beyond Fire TV and Fire OS; and Amazon Publisher Cloud adding consideration outcomes - Branded Searches and Detail Page Views - starting June 2026.

When: Announced May 28, 2026, at the APS Summit. The signal coverage report and Interactive Video Ads open beta are available immediately. PSAI open beta and Signal IQ A/B testing launch this summer. APC consideration objectives begin in June 2026.

Where: The announcements were published on the APS blog at aps.amazon.com. The capabilities apply to publisher inventory across web, mobile app, and connected TV globally, with Amazon Publisher Cloud availability currently limited to the United States and Canada.

Why: Publishers need better tools to demonstrate the revenue value of their signals to programmatic buyers as the advertising ecosystem moves away from third-party identifiers. Advertisers, meanwhile, are demanding measurable outcomes across more formats and funnel stages. The six capabilities announced today address both sides of that equation - giving publishers measurement infrastructure and deal creation tools, while giving advertisers more inventory surfaces and more granular outcome objectives.
