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Low-quality data can come in different forms, like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover), or simply the wrong relationship can be made between data sets.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

It is time for us to polish off our crystal ball and give our predictions straight from consumers’ fingertips for the hot products of the 2012 holiday season. Gadgets will reign across many ages Tablets including LeapPads, Tabeos, iPads, Kindles and others will continue to be a popular gift this year, with more choices than ever. On the list of top product-related search terms driving traffic to the Retail 500 category of sites, Kindle Fire HD and Windows 8 top the list as new products. Additionally, Meep!, a child friendly tablet appeared in the top fifteen. Accessories for both phones and tablets will also be popular, especially as the variety grows for iPhone 5 and iPad Mini. A reoccurring favorite gift for the holidays is UGGs which shows a decrease year over year. However, another brand with a similar product is Bearpaw, which is in the top ten searches and has seen big growth year over year.Source: Experian Hitwise Dolls, video games and Furbys, oh my! To identify the popular toys for gifts this year, we researched product-related search terms driving traffic to ToysRUs.com compared to last year’s holiday season. We uncovered trends in the doll category, Doc McStuffins as number one on the list, along with the classic Barbie, which saw a growth in searches year over year. The Furby is making a strong comeback at the number two spot with a reboot and new features. Another trend here is tablets, from branded searches like LeapPad and Kurio there is also the generic term ‘tablets for kids’. In the video game category, the new Wii U that is debuting just in time for Black Friday and should be a big gift this year, along with searches for PS3 games and the Nintendo 3ds xl are all in the top 20 searches.Source: Experian Hitwise Keywords of the consumer to identify demand Beyond product names, it is important to understand the actual way people search, using key phrases and questions. Last year, for example, there was a lot of activity around ‘in-stock’ products, such as the LeapPad explorer, which was hugely popular and quickly sold out in many stores. Retailers and marketers should monitor this throughout the season and make sure to optimize for in stock if there is a popular product that they have available.Source: Experian Hitwise Consumers also focus on what is the ‘best’ – so we see search activity around ‘best place to buy’, particularly around electronics. Questions such as ‘where to buy a’ specific product are also common, such as ‘where to buy a kindle’. These phrases offer opportunities to boost search campaigns by considering how consumers phrase their questions to ensure to capture these searches.Source: Experian Hitwise Quick tip: In the retail category there will tend to be a lot of retail branded store terms but to keep up with holiday search behavior and help make analysis quick, create portfolios of branded terms to easily exclude those from a certain category. When you strip out all the variations of that term you are able to gain insight into product searches that are most popular to a certain site or category.
