Published: January 5, 2024 by Experian Marketing Services

At A Glance

Truthset’s latest analysis reaffirms Experian as the leader in third-party data accuracy. Advertisers and partners can rely on Experian’s validated, AI-powered solutions to reduce waste, improve personalization, and drive measurable marketing outcomes grounded in accuracy.

Experian continues to lead in data accuracy according to Truthset’s latest analysis

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Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets.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.”

Chip Russo, President at Truthset

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.

Real-time relevance, powered by ethical AI
Experian combines validated identity data with intelligent technology to deliver marketing that works for people and brands.

Companies are striving to eliminate marketing waste and provide consumers with personalized marketing and the advertising industry can have confidence that Experian’s marketing data has been externally validated as being highly accurate.

Four ways to reduce waste and increase efficiency

Marketers are always looking for creative ways to get the most out of their digital marketing investments. While there may be different paths to optimization, reducing media spend and cutting costs without sacrificing ROI is ideal. We empower marketers to take back control of their budgets and reinvent their media strategies by leveraging the right data at the right time. And, given today’s challenging climate, there’s no better time. Every Business Has Different Deeds Whether you’re a direct-to-consumer brand building a loyal customer base or a financial service simply letting customers know you’re here for them during a challenging time– identity resolution is essential to connecting with your audience without breaking the bank. That’s why we have built solutions that provide flexibility and control when you need it most. Putting Data Into Action Experian's "Tapad Graph" is a global, privacy-safe cross device graph is one powerful file. Updated weekly, and containing customized device IDs and digital attributes, The Tapad Graph enables smarter targeting strategies and a reduction of wasted impressions. What that means is more marketing efficiency and a stronger ROI for your business. Saving resources and money sound good to you? This guide breaks down four ways you can implement cost savings measures without sacrificing performance or prohibiting KPIs. Frequency Capping and Suppression Clustering device IDs by the individual and household means you have access to more ways to reach consumers, but it doesn’t always mean you should be using all of them across every campaign. Hone in on the channels and devices where consumers make most of their lower funnel decisions and purchases – and cap brand-awareness level placements or aspirational media that requires more exposure to generate engagement. This doesn’t mean limiting the devices you target, but being more aware of how often you’re targeting the same person across those devices. If you’ve successfully begun, or heck, even completed the consumer journey with an individual, congratulations. Now, you may want to consider what to do with the rest of the digital devices and users in that same household. Sure, there’s a time for conquesting an entire home of purchasers, but that’s not always the most effective way to maximize your media. That’s why The Tapad Graph is built to be flexible, providing a holistic view of all individuals and their associated devices and digital IDs – so you can suppress them once you’ve conquested the household decision maker or achieved the desired lower funnel activity. Save those impressions for someone else and save money for yourself. The great thing is whether you’re uploading this data into a DMP or a DSP, you can segment your target audience with a frequency cap threshold or suppress them entirely. Not only can you apply these tactics across traditional digital media, but we can include Connected TVs for OTT targeting as well, making your media strategy as holistic as your identity resolution tactics. Cross-Device Targeting and Attribution Consumer behavior and device trends are changing these days, so shouldn’t your digital marketing change too? Desktop usage is now up as much as 22%* as more people are working and learning from home. And remember that old iPad? With more people at home, we’re dusting off more devices and tablet activity is increasing more than 30%*. Sure, people are still constantly on mobile– but it might be time to consider implementing cross-device targeting and optimization for those dayparts when their focus is elsewhere. Identity resolution should be a key element of customer journey mapping and attribution in order to truly give credit to the right channels and build a baseline for the right cost-per modelling. Coupling The Tapad Graph with raw events data can granularly attribute engagement, actions and conversions at the digital ID, device, and even user-level – thereby teaching you more about your customer’s preferences. Leverage these insights to create more tailored messaging and promotions on your owned and operated channels, to funnel impressions to specific screens and platforms, and to target users based on where they are in the purchase funnel. Data That Gives You Control If you’re already implementing cross-device, have you started suppressing the devices where engagement with your brand isn’t happening? That’s right, you can use The Tapad Graph after-the-fact as well. Weekly graph updates with 60-day look-backs enable weekly campaign optimizations. That gives you the flexibility and control to avoid devices and platforms where users aren’t as active. You can only make decisions based on the data you have in front of you, so make sure you're partnering with the right solutions for your business. Does identity resolution sound like something you need? Contact us and we can help you get started with all that The Tapad Graph has to offer. Contact us today
