Truthset’s latest analysis reaffirms Experian as the leader in third-party data accuracy.

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Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets.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 in accuracy for eight marketing data attributes, including but not limited to Age, Geography, Presence of Children, and Education
- 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.

Marketers Using Centro’s DSP Basis Can Leverage Tapad’s Technology for Extended Cross-device Reach Chicago – May 15, 2018 – Centro, a provider of enterprise-class software for digital advertising, today announced that its Basis programmatic ad platform has licensed cross-device marketing technology from Tapad, a part of Experian, the company reinventing personalization for the modern marketer. Media professionals using Basis can now drive better performance by identifying a person across the different devices he or she uses, serving ads in the most optimum environment, then analyzing performance to see what ad worked best based on creative, device, location and time of day. Today’s digital media ecosystem is fragmented. People consume content on their multiple devices from multiple locations. According to digital analytics firm GlobalWebIndex, a typical consumer owns three digital devices and has seven digital ID’s active in the last 60 days. Advertising technology that treats every device as a single user would not be able to guide customers down the marketing funnel according to how users jump from one device to the next. Furthermore, they wouldn’t see when conversions occur on a device different from that in which the ad was first shown to the user. The Tapad Graph identifies the point of conversion across all screens – smartphones, tablets, home computers, and smart TVs – so that marketers can better gauge the efficiency and return on ad spend. “Our technology helps brands gain a deeper level of understanding of their customer, enabling marketers to better deliver services and products users want,” said Chris Feo, SVP of Global Data Licensing and Strategic Partnerships, Tapad. “With our technology as part of Basis, Centro is providing robust, accessible tools for marketers that want to advance their knowledge of the consumers they want to reach.” Centro’s Basis enables advertisers to plan, buy and analyze real-time bidding (RTB), direct, search and social campaigns in a single platform. It is the only platform that combines all of these elements with cross-device conversion attribution and advanced reporting features in a DSP. With the Tapad Graph integrated into Basis, marketers can now identify consumers across all of their devices during any point of the consumer journey. This can help marketers determine ad spend effectiveness for optimizing campaigns in real-time or for the future. Other cross-device marketing capabilities for Basis users include: Frequency Capping: Apply frequency caps at a unique person-level rather than at a device-level to prevent saturating users with ads and showing them more impressions than desired. Audience extension: Expand the reach of a campaign by learning what other devices a single user may have, then deliver ads to single users’ other devices. Reporting insights: Learn how users interact with ads across their devices. Gain insight about how consumers respond on devices to improve targeting parameters. Conversion attribution: Record conversions on devices different from that in which the ad was displayed to learn the true effectiveness of advertising efforts. “Cross-device analytics and optimization aligns with our vision that converging the different parts of digital media to create a holistic view of campaigns will drive performance,” said Katie Risch, EVP of customer experience, Centro. “Having Tapad’s powerful capability of personalized marketing gives our advertisers high-quality data to cultivate relationships with customers, wherever they are in digital channels.” About Tapad Tapad Inc. is the marketing technology company reinventing personalization for the modern marketer through its identity-driven solutions. The company's signature Tapad Graph connects millions of consumers across billions of devices.

The concept of identity resolution has emerged over the years as a strategic imperative among marketers and technology vendors. A report by Forrester contends that accurately establishing and maintaining customer identity is one of the most perplexing challenges facing marketers today. Customers have footprints in the offline and online worlds and tend to seamlessly transition across various channels and devices – presenting a unique challenge to truly understand who they are. But the ability to stitch these disparate components of information together means marketers can make better decisions and have more meaningful interactions with their customers. And for customers, this means an experience with personalized advertising content more likely to resonate with them. Why should marketers prioritize identity? The ability to accurately identify customers is the most basic prerequisite for marketing analytics, orchestration and execution. As such, it is becoming increasingly important for brands and marketers planning to link together disparate systems of audience insights and engagement to foster a more seamless and personalized omnichannel customer experience. For example, if an advertiser can identify a customer’s interests, as well as how that person prefers to consume information, then the advertiser can create and deliver messaging that will resonate with the customer. However, like most competitive differentiators, the mission critical components to accurately determine an identity reside within the suite of identity management tools at the marketers’ disposal and the expertise required for proper execution – a struggle for most marketers. But when properly implemented, a comprehensive customer identity strategy can be among a brand or marketer’s most valuable and proprietary assets. Where to begin with identity resolution? With the convergence of CRM platform data, cross-channel online touchpoints, offline record linkage management, probabilistic cross-device graphs, and data onboarding—evolving from point solutions to unified platforms—marketers are faced with an increasingly complex set of challenges in addressing and solving for customer identity management. To properly implement from the get go, and to avoid having to bolt on disparate technologies down the road, emerging industry trends and success stories suggest marketers need a neutral technology service provider that can provide each of these solutions via a single, unified platform. A vendor that can build a solid identity management foundation comprised of omni-channel targeting and attribution, cross-device resolution, online-offline linkage management, and data onboarding form the nexus of a cohesive identity strategy, built to last. Experian helps connect consumer identity As a trusted name in data and information services for more than 40 years, we are committed to privacy by design and the responsible usage and security of data. Whether you’re a brand, agency, or publisher, Experian has the wide-ranging toolset to help you put people at the heart of your business and make better marketing decisions.
