Comscore adds Proximic contextual and ID-free predictive audience segments to Amazon DSP

Amazon is expanding its ad-targeting options through a new integration announced by Comscore, bringing Proximic audience segments into Amazon DSP, Amazon’s demand-side platform used by advertisers to buy and manage digital ad inventory across the company’s advertising channels and partners.

In the announcement carried by Yahoo Finance, Comscore said Amazon DSP now incorporates Proximic contextual and ID-free Predictive Audience segments. Contextual targeting refers to selecting ads based on the content being viewed, while predictive audience segments are designed to infer likely interests or behaviors ahead of time.

The specific emphasis in the integration is on “ID-free” predictive audience segments, a category built to reduce reliance on individual identifiers. In practice, that typically means audience modeling that does not depend on a persistent cross-site ID to recognize particular people, though the exact implementation details were not laid out in the post.

Comscore also described the segments as “Proximic contextual and ID-free Predictive Audience” offerings, suggesting that its Proximic product provides both contextual indicates and audience predictions that can be activated in a buying platform like Amazon DSP. Amazon DSP’s role is to let brands and agencies operationalize those targeting criteria during campaign setup and optimization.

The update was reported with an effective date of June 24, positioning it as a capability change rather than a campaign outcome. The Yahoo Finance item did not include performance metrics, customer names, or contract values tied to the integration, so readers are left without confirmation of revenue impact or measurable lift from the added segments.

For Amazon, incremental improvements to Amazon DSP targeting and data partnerships matter because the platform competes on how reliably advertisers can reach relevant audiences while staying within evolving privacy constraints. With “contextual” and “ID-free” elements, the integration aligns with a broader industry shift toward indicates that can be used even as restrictions on identifiers tighten.

Comscore, meanwhile, is positioning its audience products as usable inside major buying workflows. The integration also implies that advertisers who already use Amazon DSP can potentially add Comscore-backed audience definitions without replacing their existing DSP stack, though no specifics were provided on how quickly campaigns can adopt the new segments or how activation works operationally.

Still, key details remain undisclosed in the announcement as presented. The post did not specify geographic coverage, refresh cadence for predictive segments, how advertisers can combine these segments with their own targeting, or what measurement approach is available inside Amazon DSP for attribution and optimization. It also did not confirm whether the integration is available to all advertisers immediately or only through specific plan tiers or account configurations.
