Roku becomes Google's inaugural partner for an encrypted identity solution that maps Google IDs to publisher IDs, expanding deterministic CTV targeting across Display & Video 360.
Google yesterday unveiled Confidential Publisher Match, a new deterministic identity solution, and named Roku as its first publisher partner - an announcement made during the Google NewFront 2026 livestream, which aired at 11:30am ET on March 23, 2026.
The integration connects Google's demand-side platform, Display & Video 360, with Roku's streaming inventory through encrypted identity matching. At its core, the solution maps Google IDs to Publisher IDs, allowing advertisers to match their first-party data with Roku's audience without exposing underlying personal information. According to Roku's announcement published March 23, the company "will provide Display & Video 360 advertisers with greater access to encrypted, identity matching for Roku Media in Display & Video 360."
For programmatic teams and media buyers already working within Display & Video 360 or measuring via Campaign Manager 360, this is a direct capability addition. No workflow changes are required to access Roku Media through existing SSP paths, according to the company.
The name draws directly from a line of Google identity infrastructure that has been building since at least September 2024. Google introduced Confidential Matching that month as a default for Customer Match and Google Ads Data Manager, using Trusted Execution Environments - specialized hardware and software combinations that isolate data during processing. The key technical claim is that no party, including Google itself, can access the data being processed within the TEE.
Confidential Publisher Match appears to extend that same TEE-based infrastructure to publisher-side identity reconciliation. Rather than relying on third-party cookies or probabilistic identifiers, it performs what the industry calls deterministic matching - meaning the identity signal is based on verified, logged-in user data rather than inferred from behavioral signals.
The underlying protocol structure is related to PAIR - Publisher Advertiser Identity Reconciliation - which Google's Display & Video 360 team originally developed in October 2022 and later donated to the IAB Tech Lab. IAB Tech Lab launched the PAIR protocol as an industry standard in September 2024, and version 1.1 followed on July 16, 2025, featuring clearer technical definitions, standardized Base64 encoding handled by Data Clean Rooms, and a new Open PAIR prebid module. The January 2025 rollout of broader PAIR availability across Display & Video 360 - which at that point had already been adopted by over 20,000 publisher domains through LiveRamp's Authenticated Traffic Solution - provides the technical ancestry for today's publisher-specific iteration.
What Confidential Publisher Match adds to that lineage is a publisher-centric framing. The mapping direction is explicit: Google IDs go to Publisher IDs. This distinction matters operationally. Advertisers who buy Roku Media programmatically through Display & Video 360 can now leverage Google's first-party data infrastructure to recognize Roku viewers, improving household-level targeting precision. The match rate improvements that flow from this - meaning the percentage of ad requests where an advertiser's audience data can be linked to a specific viewer - directly affect bid competitiveness. Higher match rates mean more impressions qualify for audience-targeted bids, which influences CPMs across the board.
According to the Roku announcement, the integration "improves match rates and audience targeting for Display & Video 360 campaigns with Roku Media. By providing a stronger identity signal on Roku Media, we help advertisers who care about deterministic matching achieve better targeting and stronger bid competitiveness."
Roku described three distinct use cases for Display & Video 360 buyers. The first is what the company calls holistic management - the ability to control YouTube and Roku Media campaigns within a single Display & Video 360 interface simultaneously, drawing on Google's first-party data for both. Previously, a media planner running a cross-screen campaign spanning YouTube and Roku would operate with meaningful data asymmetry: rich Google-side identity on YouTube, weaker identity on Roku. This integration is intended to close that gap.
The second use case involves household recognition rates. Roku framed this as unlocking superior bidding outcomes in both Display & Video 360 and Campaign Manager 360. Better household recognition means the system can deduplicate reach more accurately and avoid over-serving the same household with repetitive creatives - a persistent frustration in connected television buying.
The third is measurement reach. According to the announcement, enhanced measurement capabilities will apply to Roku Media tracked via Campaign Manager 360 "regardless of the buying platform." That last phrase carries specific weight. A brand buying Roku inventory through a direct insertion order - rather than programmatically through Display & Video 360 - can still have that exposure measured within Campaign Manager 360 when Confidential Publisher Match is in place. The practical example given is telling: a brand can now determine whether it reached a viewer on Roku during a live event like the X Games on The Roku Channel, then re-engage that same viewer with specific content on YouTube.
Today's Google announcement does not occur in isolation. It lands within a deliberate and systematic expansion of Roku's identity partnerships across demand-side platforms - a strategy that has been accelerating throughout 2024 and 2025.
The most significant previous milestone was the Amazon Ads and Roku partnership announced June 16, 2025, described at the time as the largest authenticated Connected TV footprint available to advertisers in the United States. That deal established a shared ad identifier system granting Amazon DSP access to an estimated 80 million U.S. CTV households - over 80% of all CTV households according to ComScore data at the time. Early testing showed advertisers reached 40% more unique viewers with the same budget while reducing ad frequency by nearly 30%. Crucially, that partnership operated at the OS level - meaning the identity integration ran through Roku's operating system itself, rather than through media-level matching.
The Google partnership announced today operates at the media level, through Display & Video 360 and existing SSP paths. According to the announcement, Roku's identity integrations now span Display & Video 360, The Trade Desk, and Yahoo, completing what the company calls its "media based DSP partnerships" - alongside last year's OS-level integration with Amazon. That four-platform identity stack means Roku can now offer deterministic matching to buyers entering through any of the major programmatic pathways.
Roku launched its self-service Ads Manager platform in September 2024, a move aimed at performance-focused advertisers who typically buy through search and social. The Roku Exchange launched in June 2024 specifically to give advertisers direct programmatic access to Roku inventory across major DSPs including Display & Video 360, The Trade Desk, and Yahoo DSP. The Confidential Publisher Match integration is, in structural terms, a capability upgrade layered on top of that existing programmatic infrastructure.
Measurement has been an equally active front. Nielsen and Roku deepened their partnership in December 2025, with The Roku Channel ranked second in ad-supported TV time. In July 2025, Roku-powered devices captured 21.4% of total TV viewing time - the third consecutive month surpassing broadcast. With approximately seven in ten TV streaming hours now ad-supported according to Nielsen, the pressure on measurement accuracy and identity fidelity across programmatic pipes is substantial.
The announcement came during Google's NewFront 2026 presentation, which focused on what the company described as "the Gemini advantage in Google Marketing Platform." The 64-minute livestream, held March 23, positioned Gemini models as embedded throughout the advertising stack - from creative generation to audience targeting and campaign measurement. PPC Land covered Google's NewFront 2026 plans in late February, noting that the session would specifically address Display & Video 360's CTV capabilities "beyond streaming."
NewFronts is the annual digital media marketplace event where major platforms present streaming and video advertising capabilities to buyers and brands. Google used its 2024 NewFront slot to announce deeper integrations with Disney's Real-time Ad Exchange, Paramount Advertising, and Warner Bros. Discovery. PPC Land covered those DV360 updates at NewFront 2024, which also introduced audience persona features and privacy-focused targeting tools. The Roku announcement today continues that pattern of using NewFronts to signal major publisher-level integrations.
At the 2025 NewFronts, held May 5, Google disclosed that Display & Video 360 reached 98% of CTV households in the United States, with access to more than 5 billion hours of ad-supported viewing monthly. That figure was claimed as 40% more watch time than The Trade Desk and 90% more than Amazon DSP at the time.
The shift toward deterministic identity in CTV advertising has been the dominant structural theme across programmatic for the past two years. Third-party cookies, never central to television advertising in the way they were to web display, are nonetheless only one part of a broader identity question. The real challenge in CTV has always been household-level recognition - knowing with confidence that the same household saw an ad on Roku, on YouTube, and on linear television, and being able to attribute conversion outcomes to each touchpoint.
Confidential Publisher Match, as described, is an attempt to give Display & Video 360 buyers a cryptographically secure bridge between Google's identity infrastructure and Roku's publisher-side data. The TEE-based architecture means advertisers can submit their first-party customer data - hashed email addresses, for example - and have that data matched against Roku viewer data inside an isolated computing environment, without either party seeing the other's raw dataset.
The absence of required workflow changes is operationally significant. Programmatic buying teams have consistently resisted identity solutions that require separate activation paths, new deal structures, or additional onboarding steps. Delivering the capability through existing SSP infrastructure removes that friction. Whether match rates and bidding outcomes improve as advertised will only become clear as campaigns run through the system at scale.
The broader competitive dynamics are worth noting. Magnite's Live Scheduler, launched November 2025, cited Roku's identity framework specifically as an enabler of live-event advertising efficiency. Criteo and WPP Media's commerce-driven CTV activation, announced July 2025, also included Roku as a pilot partner. The pattern is consistent: Roku is systematically adding identity and measurement integrations across the major nodes of the programmatic ecosystem, making its inventory more addressable and more attributable regardless of which DSP a buyer uses to access it.
Who: Roku and Google, with Roku serving as the launch partner for Google's new identity solution. The announcement was communicated directly to press by Nick Hovis of Archetype, representing Roku Advertising.
What: Google launched Confidential Publisher Match, a deterministic identity solution that maps Google IDs to Publisher IDs, enabling encrypted first-party data matching between Display & Video 360 advertisers and Roku's streaming inventory. Roku is named the first publisher partner, with the integration operating through existing SSP paths and no required workflow changes for Display & Video 360 buyers.
When: The announcement was made during the Google NewFront 2026 livestream on March 23, 2026, at 11:30am ET. Roku's formal blog post carried a March 23 datestamp; the press notification reached PPC Land on March 24 at 00:40.
Where: The integration operates across Roku's streaming inventory within the Display & Video 360 and Campaign Manager 360 ecosystem. It is available to Display & Video 360 buyers via existing SSP infrastructure, initially in the United States market.
Why: Deterministic identity in connected television advertising has become a central priority for programmatic buyers, as third-party cookie deprecation and the fragmentation of streaming audiences have reduced the reliability of probabilistic signals. Roku and Google are expanding their existing partnership to give Display & Video 360 buyers household-level recognition at scale on Roku inventory, improving targeting precision, bid competitiveness, and cross-platform measurement through Campaign Manager 360 - regardless of whether the underlying buy is direct or programmatic.
