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Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets.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

In this blog post, we’ll recap Gilberti’s discussion about advertising on CTV. CTV's transformative impact on media consumption CTV brings together the nostalgia of traditional television and the cutting-edge capabilities of digital targeting, opening new doors for advertisers to connect more meaningfully with audiences. This integration heralds a new wave of viewer engagement opportunities. The revolution goes beyond altering content consumption modes; it fundamentally transforms how audiences interact with media. Advertisers now have the tools to forge deeper, more personalized connections with their audience, thanks to CTV. "The evolution of media is exciting, offering endless opportunities due to the vast inventory and engaged audiences. The key to using this is understanding the consumer, the 'who' behind the viewing."kimberly gilberti, chief product officer The evolution of advertising on CTV In CTV, traditional advertising strategies are being re-evaluated. Advertisers must pivot to meet changing viewer trends, focusing on campaigns that resonate on a personal level and harness the targeted delivery capabilities of the medium.

Additionally, the fragmentation of content across multiple streaming platforms amplifies the challenge of reaching specific audience segments. The presence of 'walled gardens' adds another layer of complexity in achieving a comprehensive understanding of audience behavior across different platforms. Despite these challenges, the potential for effective, personalized advertising on CTV is immense. Key to unlocking this potential is the accurate measurement of ROI and the alignment of content with viewer preferences. These areas of focus underscore the need for sophisticated identity resolution and audience analysis solutions. Collaboration is the key to unlocking CTV's potential The future of advertising on CTV relies on collaboration. Joint efforts from advertisers, agencies, technology providers, and publishers are essential for sharing data and insights while maintaining consumer privacy.
