Advertisers, technology partners, and agencies are all chasing accurate data to power their marketing strategies. But not all data is created equal. Truthset’s latest findings confirm Experian’s leadership in third-party data accuracy, giving brands and agencies confidence in every decision they make.
Accurate data is the foundation for predictive insight, real-time intelligence, and AI-powered personalization. Experian’s AI-driven solutions help marketers move from data to action, delivering more relevant messages with less waste.
Truthset’s independent study found that up to 51% of ad targeting data is inaccurate, with accuracy rates ranging between 32% and 69% across providers. This reinforces the importance of validated, trusted data from partners like Experian.
The data quality challenge
Inaccurate data can lead to:
Wasted ad spend
Without accurate data at the start, marketers can’t reach the right audiences, resulting in wasted impressions.
Privacy and compliance risks
In an increasingly privacy-centric world, advertisers need to be especially mindful of accurate targeting to avoid putting their brand reputation at risk.
Poor campaign performance
Low-quality data skews metrics and attribution models, making it difficult to measure campaign success and optimize spend.
Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets. Data records can be incomplete or duplicative, and data segments could be misclassified or inaccurate. For example, a kids’ snack food company may think they’re targeting a 35-year-old man, who lives in the suburbs with his young family, when in fact it’s a 65-year-old woman who moved to the city after her kids went to college. That’s wasted investment.
As data ecosystems grow more complex, that’s where Experian’s AI-powered simplicity comes in. We can clean, enrich, and infer missing signals, helping you act on incomplete or imperfect data with greater confidence.
Building a solid data foundation
Accurate data is essential for personalization and trust. According to eMarketer, more than 75% of internet users worldwide are willing to share their email address, brand interest, and name in exchange for personalized experiences. Without accurate data, marketers won’t be able to provide the level of personalization that consumers desire.
But personalization at scale requires more than just data, it needs intelligence. Experian’s AI-powered capabilities, including predictive models, transform clean, validated data into meaningful engagement strategies that balance performance with privacy. Independent validation from Truthset ensures that Experian’s data remains among the most accurate in the ecosystem.
“As cookies and mobile ad identifiers continue to phase out, consented, durable identifiers (hashed email, postal addresses) are going to serve as the foundation for identity solutions of the future. And the only way to ensure you are transacting on the highest quality identity and demography data is to actively validate the data you rely on with a third party.”

Experian’s commitment to data accuracy
Since joining the Truthset Data Collective in 2023, Experian continues to be the industry leader in data accuracy. Truthset’s latest Q2 2025 analysis reaffirms our leadership in data accuracy:
- Experian is the #1 data provider of largest volume of high-accuracy hashed emails (HEMs)

- Experian ranks #1 or #2 for 22 of the 24 attributes, and #3 for the two others (out of 12 companies being analyzed)
- Experian consistently has the largest number of HEMs that are 90% or more likely to be accurate
“As a member of the Truthset Data Collective, Experian received top ranks across a variety of categories for its data. The entire digital advertising world runs on data, but focusing on data accuracy is going to drive the next phase of innovation for the industry, enhancing ROI for advertisers, CPMs for publishers, and relevant experiences for consumers.”
Chip Russo, President at Truthset
As Truthset’s recent study highlights, the data matched between hashed emails and postal addresses is crucial, underpinning everything from targeted ads to TV audience measurement. Highly accurate HEMs linked to high-quality demographic data should be the foundation of any marketing plan. Advertisers are able to overcome the complexities of identity resolution by tying online and offline touchpoints together to deliver a consistent message across channels.

Cross-Screen Pioneer Explores the Power of Connected Cars as a Vehicle for Customer Engagement LAS VEGAS, NV — (October 26, 2016) –Kate O’Loughlin, GM of Media for Tapad, addressed the J.D. Power Automotive conference audience today in Las Vegas, NV. With more than 1,400 participants representing every facet of the automotive marketing profession, the conference has become the industry's leading marketing event. Bringing the unified, cross-screen perspective to the stage, O’Loughlin discussed the vital role of connected cars in the consumer engagement process. She is a founding member of Tapad which launched the world’s first cross-screen marketing technology in 2010. Tapad was acquired by the Telenor Group early in 2016. Key points from O’Loughlin’s J.D. Power 2016 address included: The marketers who deliver relevant and engaging content in a privacy-safe setting will be in the strongest position to navigate the proliferation of connected devices, including the connected points in cars. As automakers innovate the technology in cars, marketers need to be prepared for the size and diversity of data available for understanding consumers. It’s going to be increasingly difficult to wade through the data, so now is the time to build a solid framework for understanding the person behind the data. Marketers who evolve — and take a holistic approach — to their campaign measurements will achieve marked improvements in efficiency and an enhanced understanding of their core audiences. Actionable brand engagement metrics like Viewable Exposure Time (VET) will continue to overtake traditional advertising performance metrics. VET evaluates the optimal amount of time an ad is present on a screen to incite consumer action. In early testing by Tapad, campaigns that employ VET see conversion rate performance improvements from 13 to 60%. The consumer-centric technology solutions of the future need to be as scalable as they are affordable. Learn more about Tapads’ recommended Viewable Exposure Time metric contact us today!

NEW YORK, Sept. 28, 2016 /PRNewswire/ – Tapad, the leader in cross-device marketing technology, today announced a new metric for cross-device marketers, Viewable Exposure Time (VET). Viewable Exposure Time measures across screens and ad formats, identifying the optimal amount of time a consumer spends with an ad before they take action. The announcement coincides with Unify Tech '16, Tapad's third-annual cross-device summit during Advertising Week NY. Frequency caps are currently used to ensure that dollars aren't wasted on redundant ads. Viewable Exposure Time evolves the frequency capping approach to include accelerating a consumer's ad exposure rate up to the optimal time spent with the brand. VET is used in affinity, digital transaction and offline purchase models as a key indicator of marketing budget well-spent. Beta users of VET span every vertical, though interest is especially high from CPG, Automotive, Telecommunications and Retail. Viewable Exposure Time unifies and upgrades marketers' predictors of advertising success by leveraging cross-screen engagement across digital and television, with vendor-agnostic viewability scores for video, rich media and display. "Today's current measurement options, like click-through rate (CTR) and TV gross ratings points (GRP) tell an incomplete story," said Tapad GM of Media Kate O'Loughlin. "Tapad is focused on measuring what really matters to marketers – building an efficient connection with a customer. Innovation in metrics was long overdue." More than just a measurement tool, Tapad also provides clients with VET activation. Factoring in time spent with ads in viewable seconds and minutes, these analytics inform marketers about which audiences are underexposed, enabling them to adjust campaigns and deliver according to optimal viewable exposure time. This effectively increases conversion rates at the lowest cost. Contact us today
