by Experian Marketing Services 4 min read November 2, 2026

At A Glance

A leading auto manufacturer used Experian Curated Deals to reach eco-friendly auto shoppers and electric vehicle (EV) enthusiasts across display, video and connected TV (CTV). This automotive advertising case study shows a 76.4% more efficient cost per acquisition (CPA), the most efficient CPM among partners, with Experian Curated Deals powering more than 90% of conversions.

Key takeaways

  • The campaign reached a $1.18 CPA, 76.4% more efficient than the campaign average, and a $15.82 CPM, the most efficient of all partners.
  • Experian Curated Deals package premium publisher inventory, privacy-safe audience data and dynamic pricing into one deal ID, so buyers skip separate data and inventory purchases.
  • The agency used Experian Curated Deals to build EV-focused deals around two core audiences, eco-friendly auto shoppers and electric vehicle enthusiasts, anchored in Experian audience data.
  • The deals blended premium inventory, including AutoGuide.com, AutoSport, AutoZone, Cars.com, Motor1.com, and J.D. Power, with curated EV signals.

What challenge did the auto manufacturer face with its EV campaign?

The auto manufacturer faced two challenges in its EV campaign: reaching eco-friendly auto shoppers and EV enthusiasts at scale across display, video and CTV, and proving how its media partner performed against every other partner. This automotive advertising campaign ran through a large holding company agency and required a partner that could combine premium audience data with premium inventory across all three channels.

Just as important, the manufacturer wanted clear, comparable proof of performance: a view of how this partner’s results compared with every other partner in the campaign.

What are Experian Curated Deals?

Experian Curated Deals builds private marketplaces (PMPs) that combine premium publisher inventory, privacy-safe audience data, and dynamic pricing into a single, ready-to-activate deal ID. Instead of buying audience data and inventory separately and hoping they line up, a media buyer activates one packaged deal that already combines both.

For a marketer, that means:

Reaching specific, named audience segments using privacy-safe, ID-based and ID-less targeting, without building a separate targeting layer

Activating premium inventory across display, video, and CTV through one deal rather than coordinating multiple vendors

Comparing performance on consistent terms, since the same curated deal runs across channels and against other partners in the same campaign

How did the auto manufacturer’s agency use Experian Curated Deals for the EV campaign?

The agency used Experian Curated Deals to build EV-focused deals around two core audiences, eco-friendly auto shoppers and electric vehicle enthusiasts, anchored in Experian audience data. Experian served as a consistent curation partner for the auto manufacturer, applying audience data and predictive targeting through those deals.

The deals blended premium inventory, including AutoGuide.com, AutoSport, AutoZone, Cars.com, Motor1.com, and J.D. Power, with curated EV signals. That gave the agency a single, ready-to-activate path to premium, addressable inventory across display, video, and CTV, instead of separate placements to manage and separate results to reconcile.

What results did the auto manufacturer see from Curated Deals?

  • 76.4% more efficient CPA
  • Most efficient CPM in the campaign
  • Experian Curated Deals powered more than 90% of total campaign conversions

A deep dive with an Experian partner, ARF

In our Ask the Expert series, we interview leaders from our partner organizations who are helping lead their brands to new heights in AdTech. Today’s interview is with Samantha Zhang, Senior Data Scientist, and Jim Meyer, General Manager of the DASH TV Universe Study at the Advertising Research Foundation (ARF). DASH is an annual tracking study conducted by the ARF to define and better understand TV audience behavior and household dynamics. What does DASH measure, and how does it help the industry understand TV consumption today?  By capturing hundreds of individual- and household-level data points from each respondent in a rigorous and nationally projectable sample, DASH creates a comprehensive picture of U.S. consumer TV “infrastructure” – how America watches.  Core elements in DASHElements that create context in DASHTV setsLocation | brand | smartness | service modes | sources DemographicsConnected devices Game consoles |video players | streaming devicesYesterday viewing Daypart | TV/device genre | Out-of-home viewingMobile devicesOwners | sharing usersShoppingOnline and in-store | Exposure to major RMNsInternet serviceModes | ISPs | connectivity by device Streaming audio Streaming TVSVOD/AVOD tiers and sharing | FAST Email accounts and apps Live TV Modes of access | including casting from devices Social media For example, DASH gathers: Data on every TV set, including brand, room location, age, “smartness,” and connection devices and modes  Household connectivity and video service data, even in homes with no TV set Internet Service Providers (ISP) and TV service usage, including Multichannel Video Programming Distributors (MVPDs), virtual vMVPDs, streamers (ad-supported and premium), and Free Ad-Supported Television (FAST) channels  Person-level ownership and usage of video-capable mobile devices, including smartphones, tablets, and laptops  Measures of viewing and co-viewing across dayparts, devices, and services  Additional modules covering shopping and retail media networks, streaming audio, social media, email, and apps Broad coverage and granularity make DASH a uniquely robust source of truth for practitioners across the industry, including measurement experts and ad programming strategists. DASH also reports regularly (and publicly) on key industry dynamics. DASH identified a growing segment of device-only viewers – now nearly 9 million households that watch TV, but do not own a TV set – and highlighted the implications of that trend for traditional ratings systems based only on households with TV sets.  Households (HHs – million)2025 HHs (M) U.S. penetrationChange vs. 2024 (M)Total US134.8100%+2.7Connected TV (CTV)114.685%+2.1TV (Set)124.292.2%+1.1Device-only8.86.6%+1.6TV-Accessible133.198.7%+2.7 DASH called out the rise in app-based pay TV and proposed a new connection framework that better represents the modern TV world, in which linear and streaming overlap. DASH also defines the universes of households reachable with advertising. This graphic, for example, shows how all ad-supported linear and streaming properties in aggregate define the true scale of TV advertising. While 35 million households (and growing) are reachable only with streaming ads and 13 million (and falling) only with linear ads, most households are reachable with both, underscoring the importance of understanding the “overlap.” Who uses DASH data, and what decisions does it help inform? There are three primary users of DASH, each with its own use cases: Measurement providers, including Nielsen, use DASH to calibrate viewership data, turn household data into persons data (and vice versa) and estimate potential reached audiences–what the providers call media-related universe estimate (MRUEs)–for the calculation of ratings. Not surprisingly, measurement companies were the first to see the value that an independent TV universe study could provide. Media companies, including major broadcasters and streamers, use DASH to add context and color to their ad sales presentations – and to track the measurement providers, whose ratings play a major role in valuing ad inventory. AdTech companies, including Experian, use DASH to create high-value audience segments for activation. The recent accreditation of DASH by the Media Rating Council (MRC) and adoption by Nielsen as an input to its TV ratings have generated interest from a broad range of companies. We are actively pursuing new licensees and partners to make DASH more useful within, and even outside, the TV ecosystem. What does MRC accreditation signify, and why is it meaningful for DASH?  MRC accreditation means DASH passed a rigorous audit conducted by Ernst & Young over many months, which validated our methodology, controls, and data quality. MRC accreditation establishes that DASH is an industry-standard dataset.  While the service provider normally announces its own accreditation, the MRC took the unusual step of issuing its own release on DASH, announcing the accreditation of DASH for TV universe estimation and endorsing the study for broader, cross-media use. How does Experian use DASH data to build audiences?  The segments combine specific TV usage habits and behaviors from DASH with Experian data on demographics, spending, and other contextual inputs to create a fuller view of consumer viewing behavior. They are designed to be valuable to advertisers in many categories and planning contexts – and to be customizable to fit advertisers’ media targets. The segments can be used to: Apply or suppress audiences to improve target coverage across a campaign  Better align media and creative  Reach elusive but high-value viewers, such as Ad Avoiders  Drive valuable consumer behavior  Achieve specific advertising objectives What are some practical use cases for DASH-based audiences?  Here are some practical use cases for four different kinds of DASH segments in five different advertiser categories.  Travel Co-WatchersA couples-only resort uses TV Co-Watching Households without Children to strengthen target reach and ad memory recallA big theme park destination uses TV Co-Watching Households with Children to reach families in moments of togetherness Home Entertainment TV Owners and Brand LoyalistsA premium TV manufacturer uses the overlap of Multi Brand TV Owners and Single Brand TV Loyalist Households to market its newest TV model to its most loyal consumers. Fast Food Screen Size ViewersA fast food chain with a high-impact new brand campaign uses Large Screen TV Viewers to better align the media and  creativeThat same fast food chain uses Small-Screen TV Viewers to drive store traffic by increasing exposure of its retail campaign among on-the-go viewers Financial Services Cord Cutters A personal cost management app and a cash-back credit card target Streaming-First Cord Cutter Households to reach young, tech-savvy, cost-conscious consumers Thanks for the interview.
