Amazon Targets Netflix Ads with New Audience Tool
Amazon Ads announced that starting next quarter US media buyers will be able to use Amazon Audiences to target Netflix campaigns running through the Amazon DSP. The capability builds on Netflix’s September decision to make inventory programmatic in the Amazon DSP and lets advertisers cross-reference Amazon’s commerce and browsing signals with logged-in Netflix accounts. Amazon says its authenticated identity graph covers roughly 90% of US households. The move is positioned to help marketers treat streaming as a full-funnel channel by tying impressions to purchase intent and conversions. Amazon also highlighted recent ad‑tech upgrades such as Campaign Manager and a creative agent, and noted agency partnerships (including Omnicom Media) aimed at improving frequency capping and ad performance.
Netflix Leverages Amazon Data for Enhanced Ad Targeting
Netflix will enable advertisers buying Netflix inventory through Amazon DSP to apply Amazon Audiences—segments built from Amazon users’ shopping, browsing, and streaming behavior—starting in Q2 in the U.S. The capability brings retail-grade purchase signals into Netflix’s ad-supported streaming environment and will roll out to additional ad-supported markets later in the year. Netflix is also opening audience activation via Yahoo DSP using deterministic Yahoo audiences. To support performance measurement and attribution, Netflix is introducing a Conversion API that it says delivered >75% outperformance in early tests with Tinuiti. These integrations extend Netflix’s programmatic interoperability, building on the prior launch of the Netflix Ads Suite and the decision to make inventory available via Amazon DSP.
Netflix Lets Amazon Audiences Target Its CTV Inventory
Starting in Q2 2026, advertisers buying Netflix inventory via Amazon DSP can layer Amazon Audiences — segments derived from users' shopping, browsing and streaming behavior — against Netflix viewers. Netflix is also opening audience activation through Yahoo DSP with deterministic Yahoo audiences built from global interest, behavioral, purchase and life-stage signals. Netflix’s Conversion API, designed to deliver real-time campaign insights and clearer attribution, has shown strong early results in tests with Tinuiti (campaigns exceeded benchmarks by more than 75% in some verticals). Nielsen is simultaneously expanding measurement with 200+ advanced audience segments on Nielsen ONE, powered by Scarborough survey data and becoming fully shoppable in Q2. The moves combine commerce-originated audience data, streaming inventory access, and new attribution tooling — reshaping CTV targeting, measurement and the advertising conversations ahead of Upfront season.
