Netflix Boosts Ad Targeting with New DSP Partnerships
Netflix announced updates to its Ads Suite that expand audience targeting and outcome measurement for advertisers. The streamer is adding deeper integrations with Amazon’s DSP (enabling Amazon Audiences segments) and Yahoo DSP (activating Yahoo audience signals) for programmatic buys, with the integrations scheduled to go live in Q2 starting in the US and later expanding to other markets. Netflix also developed its own Conversion API (CAPI) tools to let advertisers connect marketing data—such as conversions and website activity—to Netflix’s ad platform to better attribute outcomes. The company has run tests of the CAPI tools with independent agency Tinuiti in the US and is broadening availability. These moves follow Netflix’s 2022 ad-tier launch and the rollout last year of its in-house advertising technology, reflecting a push to show measurable outcomes and give buyers more targeting confidence.

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).
