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Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets.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

Tapad, a part of Experian and the future of cookies Earlier this week, Google announced plans to create “.. a path towards making third-party cookies obsolete”; which will result in the phasing out of support for third-party cookies in its Chrome browser within two years. While there has been much discussion and debate on the future of the third-party cookie, an announcement from Google has been anticipated for some time. As many have said this week, the use of cookies and other identifiers has and will continue to evolve. What will never change is the value exchange between publishers and consumers that is enabled by relevant advertising. Notably, the need for independent companies to develop solutions that enable this value exchange has never been greater to ensure that publishers, consumers, and advertisers derive the most value from their relationship. We are well-positioned for the future From the start, Tapad, a part of Experian has led with a consumer-first, privacy-centric approach to technology as the use and proliferation of devices and global privacy regulations continue to evolve. Over the past two years, Tapad, a part of Experian has gone through a technical overhaul. Calling on almost ten years of expertise in identity resolution, we have created a modern platform that is flexible in terms of identity input as well as output. Anticipated change in the identity landscape was the driver behind our architecture decisions and what enables us to be responsive to a dynamic market. Consumer behavior and device use continue to change, bringing additional digital IDs into the equation – namely across the mobile and CTV environments. Our technology, however, is not tied to any specific type of identifier, but rather is focused on associating disparate identifiers at the individual and household level. Where do we go from here? Google’s announcement has been characterized as a conversation starter, but we see it more as a call to action. With a timeline set, there is a need to converge on one or more solutions that can scale across the web. In a post cookie world, publishers and advertisers will continue to require ways to create fair marketplaces across platforms and devices. Further, the platforms that currently power the programmatic advertising ecosystem will need to be able to invest and differentiate to bring value to their customers. Scaled privacy-safe identity solutions will be needed not only for classic targeting, attribution, measurement, and frequency capping use cases but also to carry consumer preferences and consent. Tapad, a part of Experian will continue to play a leading role here. However, we are not going to do this alone. As solutions around Google’s Chrome browser evolve, we will continue to take a leadership position and will work with Google, key industry groups, partners and customers to meet current and future needs for an independent identity solution at scale. In the meantime, we will continue to support an independent ecosystem where consumers come first and privacy standards are a priority. It’s business as usual…for now. There will not be any changes to our graph products or services as a result of Google’s announcement in the near term. Any changes related to the Chrome third-party cookie will evolve and will no doubt be subject to significant industry participation and feed-back, indeed at the invitation of Google. We will proactively communicate any changes and product updates during this time period. We look forward to the opportunities resulting from these changes and ushering in a new era of identity resolution in digital advertising. Contact us today
