Case study: How a leading auto manufacturer achieved 76.4% more efficient CPA for its EV campaign

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

Tapad, a part of Experian and the future of cookies

Tapad, a part of Experian and the future of cookies Earlier this week, Google announced plans to create “.. a path towards making third-party cookies obsolete”; which will result in the phasing out of support for third-party cookies in its Chrome browser within two years. While there has been much discussion and debate on the future of the third-party cookie, an announcement from Google has been anticipated for some time. As many have said this week, the use of cookies and other identifiers has and will continue to evolve. What will never change is the value exchange between publishers and consumers that is enabled by relevant advertising. Notably, the need for independent companies to develop solutions that enable this value exchange has never been greater to ensure that publishers, consumers, and advertisers derive the most value from their relationship. We are well-positioned for the future From the start, Tapad, a part of Experian has led with a consumer-first, privacy-centric approach to technology as the use and proliferation of devices and global privacy regulations continue to evolve. Over the past two years, Tapad, a part of Experian has gone through a technical overhaul. Calling on almost ten years of expertise in identity resolution, we have created a modern platform that is flexible in terms of identity input as well as output. Anticipated change in the identity landscape was the driver behind our architecture decisions and what enables us to be responsive to a dynamic market. Consumer behavior and device use continue to change, bringing additional digital IDs into the equation – namely across the mobile and CTV environments. Our technology, however, is not tied to any specific type of identifier, but rather is focused on associating disparate identifiers at the individual and household level. Where do we go from here? Google’s announcement has been characterized as a conversation starter, but we see it more as a call to action. With a timeline set, there is a need to converge on one or more solutions that can scale across the web. In a post cookie world, publishers and advertisers will continue to require ways to create fair marketplaces across platforms and devices. Further, the platforms that currently power the programmatic advertising ecosystem will need to be able to invest and differentiate to bring value to their customers. Scaled privacy-safe identity solutions will be needed not only for classic targeting, attribution, measurement, and frequency capping use cases but also to carry consumer preferences and consent. Tapad, a part of Experian will continue to play a leading role here. However, we are not going to do this alone. As solutions around Google’s Chrome browser evolve, we will continue to take a leadership position and will work with Google, key industry groups, partners and customers to meet current and future needs for an independent identity solution at scale. In the meantime, we will continue to support an independent ecosystem where consumers come first and privacy standards are a priority. It’s business as usual…for now. There will not be any changes to our graph products or services as a result of Google’s announcement in the near term. Any changes related to the Chrome third-party cookie will evolve and will no doubt be subject to significant industry participation and feed-back, indeed at the invitation of Google. We will proactively communicate any changes and product updates during this time period. We look forward to the opportunities resulting from these changes and ushering in a new era of identity resolution in digital advertising. Contact us today
