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

Ask the Expert: A deep dive into Kontext

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 Georgia Campbell, Head of Strategic Partnerships at Kontext.   What types of audiences does Kontext provide, and what are some top use cases for these insights in marketing strategies?  Kontext leverages its 1st-party, deterministic shopping data to generate real-time online audiences. What sets Kontext apart is our ability to see the entire consumer journey, from shopping interest to intent and purchases, at a SKU-level. This comprehensive visibility allows us to create purchase-based audiences across various consumer verticals, such as frequent online shoppers, consumers shopping for beauty, segments using Mastercard, or Black Friday enthusiasts. Our data engine, built on a foundation of approximately 100 million consumer profiles and over 10 billion full-funnel, real-time shopping events, enables the creation of precise audience segments. This real-time 1st-party shopper data is invaluable for partners aiming to understand and engage with consumers more effectively.  Whether a brand wants to activate past shoppers in a specific category or reach new audiences with a propensity to buy, Kontext provides the insights needed to make informed decisions. Some examples of audience types include these (and hundreds more):  In-Market Shoppers: Consumers showing high intent to purchase specific categories, like skincare or electronics, based on recent online behavior.  Past Purchasers: Shoppers who have made verified purchases within specific time frames, such as beauty products in the last 18 months.  Frequent Shoppers: High-frequency buyers identified through repeated purchasing behaviors.  Seasonal Shoppers: Consumers active during key shopping seasons, like Black Friday, Mother’s Day, Valentine’s Day, etc  Premium Buyers: Shoppers who used a premium CC (eg. Amex) and a higher AOV (average order value)  Beauty Buyers: an audience that has indicated intent to purchase beauty products (deterministic past purchasers also avail)  By using Kontext data, brands can identify the right audiences across multiple verticals, such as retail, CPG, health & wellness, auto, business, energy & utility, financial, and travel. Additionally, our collaboration with Experian allows further refinement of these audiences through layered data from specialty categories like demographics, lifestyle & interests, mobile location, and TV viewing habits.  How is Kontext’s data sourced, and what differentiates it from other data providers? Kontext’s data is unique because it is deterministic, 1st-party, and collected as transactions occur. We capture the entire path-to-purchase, down to the SKU-level product detail, across 100 million consumer profiles and more than 10 billion real-time shopping events. Our proprietary technology, embedded in widgets across our 5 million premium online destinations, tracks the full consumer journey—from reading an article of interest to clicking on our dynamic commerce modules, adding items to cart, and completing purchases. This real-time data collection ensures there is no lag between digital events and their connection to consumer profiles.  Unlike other providers, we do not aggregate data from multiple platforms; instead, we focus on building our models and insights based on authentic online consumer behavior. Our data stands out due to its:   Deterministic Nature: We capture 1st-party data as transactions occur (all in real time)  Full-Funnel Coverage: We capture consumer journeys from awareness to purchase, providing a complete view of consumer behavior.  Real-Time Insights: Our data engine processes events in real-time, enabling timely and relevant marketing actions.  How does Kontext ensure the accuracy and reliability of its audience data? Kontext ensures accuracy and reliability through our unique technology and direct data sourcing. By not aggregating data from other platforms, we maintain control over the quality and integrity of our insights. Our continuous investment in refining our models around online consumer behavior further enhances the precision of our audience data.  What types of brands or verticals might resonate the most with Kontext audiences for activation? Any brand looking to understand and activate online shopping behavior – informed by 1st-party transaction data – will resonate with Kontext audiences. Essentially, any vertical that benefits from understanding real-time shopping behaviors, such as retail, health & wellness, auto, and financial services, will find our data invaluable. We have particularly strong insights in beauty, hair care, health & wellness, and values-based online shopping habits, as well as the food & beverage space.   Retail & Consumer Goods: Leveraging shopping behavior data for targeted campaigns.  Health & Wellness: Identifying consumers with specific health and wellness interests.  Automotive: Targeting potential buyers of electric vehicles or eco-friendly products.  Financial Services: Engaging high-value shoppers with premium credit card usage.  And many more  How does Kontext’s data help advertisers navigate the challenges posed by the deprecation of third-party cookies?  As third-party cookies become less reliable, Kontext’s 1st-party data becomes invaluable. Our deterministic data engine, which does not rely on cookies, offers:  Direct Consumer Insights: Accurate and consented data directly from consumer interactions.  Privacy Compliance: Our data collection methods are fully compliant with privacy regulations, ensuring secure usage.  Cross-Device Coverage: We use verified digital identifiers, allowing seamless unification and targeting across multiple devices.  What measures does Kontext take to maintain data privacy and compliance, and how does this benefit advertisers? Data privacy and compliance are fundamental to Kontext. We meet or exceed all privacy compliance and security standards, ensuring that our data sourcing and usage are transparent and comply with regulations (CCPA, CPRA, VCDPA, etc). Kontext prioritizes data privacy and compliance through:  Consented Data Collection: All data is collected with explicit consumer consent.  Robust Security Protocols: Data is encrypted and secured with industry-leading practices.  Compliance with Regulations: We adhere to global privacy laws, including GDPR and CCPA.  User Control: Consumers have the ability to opt-out and manage their data preferences.  Can you share success stories / use-cases where advertisers significantly improved their campaigns using Kontext’s data? To give you a sense of how Kontext data can be applied, here are two use-cases:  Beauty Brand Campaign: An agency hoping to activate an audience of beauty purchasers for a Major Beauty Brand could utilize Kontext’s custom audience of high-value beauty product purchasers. By targeting those consumers who had bought similar products in the last 12 months and had an average cart size of over $50, the campaign would significantly increase performance and ROAS.  Electric Vehicle Launch: For a major auto manufacturer’s EV launch, Kontext could be used to identify eco-friendly consumers who had not yet purchased an EV but had shown interest in sustainable products. This precise targeting could lead to higher engagement and conversion rates for the campaign.  Thanks for the interview.
