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
