Experian received top ranks for hashed emails (HEMs) and demographic data from Truthset Data Collective
Advertisers, technology partners, and agencies are all chasing accurate data to power their marketing strategies. Turns out, not all data is created equal and unless you’re working with the right partner, high-quality data can be hard to find. That’s because accuracy can vary widely across the industry and the partner you choose is important. A recent study conducted by data validation company Truthset showed that 51% of the data used for ad targeting and audience measurement is wrong, with average accuracy rates ranging between 32%-69% across data providers.
The data quality challenge
The lack of high-quality data poses multiple challenges in the advertising world:
- Wasted ad spend: without accurate data at the start, marketers can’t reach the right audiences, resulting in wasted impressions.
- Privacy and compliance: 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Low-quality data can come in different forms like inconsistent or outdated information – think demographics (age, gender) and interests (dog versus cat lover) or simply the wrong relationship can be made between datasets. 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. It’s wasted dollars!
Build the data foundation
Data quality needs to be addressed if advertisers and advertising technology partners want to fulfill consumers’ demand for personalized marketing. Per eMarketer, more than 75% of internet users worldwide said they were 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.
Validation can help advertisers evaluate third party data and help build trust across the ecosystem. Companies like Truthset review and provide an unbiased evaluation of data fidelity and quality on a regular basis.
“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,” said Chip Russo, President at Truthset. “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.”
Not all data is created equal: Experian leads the way
In Q3 2023 Truthset reviewed Experian’s marketing data – as well as several other large data providers – and found:
- Experian is the #1 data provider in terms of largest volume of high-accuracy hashed e-mails (HEMs) with demographic data
- Experian ranks #1 in accuracy for 15 marketing data attributes, including but not limited to Age, Gender, Home Owner/Renter, Geography, Education, Presence of Children, and Pet Owner
- Experian consistently has the largest number of HEMs with demographic data 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,” continued Russo. “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.”
As Truthset’s recent study highlights, the data matched between hashed e-mails 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.
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. The accuracy of our data will power smarter marketing initiatives, like insights, targeting, identity, and measurement.
Let’s start a conversation about how we can fully realize the potential of data-driven advertising together.

In a perfect world, we’d all have a single, go-to grocery store that carried everything on our shopping list – fresh produce, gourmet coffee beans, rare spices, and maybe even that special-grade olive oil, right alongside our wholesale bulk purchases at unbeatable prices. It would be convenient and efficient, and it’d save a lot of driving around town. The changing data marketplace: From one-stop shop to specialized selection For a long time, data buyers enjoyed something similar in their world: a small set of large-scale data marketplaces that offered a wide array of audiences, making it easy to load up on whatever you needed in one place. Not only are there fewer places to pick everything up, but new factors like privacy and signal deprecation are placing a spotlight on quality and addressability. Just as our dinner plans are growing more ambitious insofar as we want health, flavor, value, and convenience all in one place – so are our data strategies. Instead of a single steak-and-potatoes meal, today’s data marketplace operators might be cooking up a complex menu of campaigns. “Experian has been a longstanding partner of DISH Media, and we’re excited to be an early adopter of their marketplace which leverages the foundation of their identity solutions to ensure maximum cross-channel reach as we look to expand the breadth and depth of data we use for addressable TV.”Kemal Bokhari, Head of Data, Measurement & Analytics, DISH Media As a result, data buyers are beginning to shop around. Some still rely on large-scale marketplaces for familiar staples, but now they have reasons to explore other options. Some are turning to providers known for offering top-tier, transparently sourced segments. Others are focusing on specialty providers that excel in one area. A more selective approach to data buying In this environment, choosing where to “shop” for data is becoming more deliberate and selective. Data buyers aren’t just thinking about broad scale; they’re looking to prioritize quality, durability, data privacy, and differentiation. They need to place higher value on data marketplaces that can maintain audience addressability over time, despite signal loss. Sometimes, that means accepting a smaller assortment in exchange for tighter vetting and more reliable targeting. Other times it means mixing and matching – stopping by one marketplace for premium segments and another for cost-friendly, wide-reaching data sets. Either way, they can benefit from having more choices. “Experian has been a longstanding partner of DISH Media, and we’re excited to be an early adopter of their marketplace which leverages the foundation of their identity solutions to ensure maximum cross-channel reach as we look to expand the breadth and depth of data we use for addressable TV.”Kemal Bokhari, Head of Data, Measurement & Analytics, DISH Media Experian’s marketplace: A trusted source for high-quality data Experian’s vetted and curated blend of data partners and vertically-aligned audiences offers a trusted specialty store for data buyers.

The future of data marketplaces: Precision and flexibility matter The evolution of data marketplaces reflects the industry's shifting priorities.

The best data strategy, much like the best grocery run, isn’t about grabbing everything in one place – it’s about carefully selecting the right ingredients to create the perfect recipe for success. This shift underscores the importance of flexibility and precision as data buyers navigate a landscape shaped by privacy regulations, signal loss, and evolving consumer expectations. As data marketplaces adapt to meet these demands, they are redefining what it means to deliver value. Experian’s marketplace enables buyers to strike the perfect balance between reach and quality by offering enhanced match rates, precise audience planning, and seamless distribution. In this new era, data buyers have the tools and options to craft campaigns that are impactful and aligned with the increasingly selective and privacy-conscious digital landscape.

We spoke with industry leaders from Ampersand, Basis Technologies, Captify, Cuebiq, CvE, Fetch, Madhive, MiQ, and Samsung to gather insights on how innovations in data and identity are creating stronger consumer connections. Here are five key insights to consider. 1. Build on trust with first-party data Stricter privacy regulations and growing customer expectations mean businesses must rethink how they gather and use data. A robust first-party data strategy centers on gathering high-quality data, such as behavioral and transactional data. By using behavioral, lifestyle, and purchasing data, brands can craft personalized strategies that align with their goals. This approach balances effective targeting with building trust and complying with privacy rules. Integrating identity solutions like Unified I.D. 2.0 (UID2) and ID5 into existing data strategies improves interoperability across platforms while keeping user privacy intact. These tools help create more effective campaigns. "We've been preparing and leaning into educating our clients around the value of first-party data. These are very important and primary considerations in any of our campaigns."April Weeks, Basis Technologies 2. Align metrics with business goals To demonstrate clear value, campaigns need to tie their outcomes to broader goals. Relying only on click-through rates or CPMs won’t cut it. Metrics that measure meaningful results, like driving sales or increasing customer retention, provide greater transparency than surface level data, like clicks or impressions. A continuous feedback loop between targeting and measurement ensures campaigns can be refined to better align with business objectives. This feedback helps marketers understand who they are targeting and how those audiences are driving key business results. Shifting focus to metrics that resonate with stakeholders ensures that marketing efforts are evaluated based on their true contribution to the company's objectives. "The television industry has access to more data than ever before, and at Samsung Ads, our ACR technology helps us provide valuable insights about what content and ads are being viewed. This abundance of data enables us to support clients in aligning their campaigns with business objectives effectively."Justin Evans, Samsung Ads 3. Personalize experiences to boost engagement Personalization drives stronger customer relationships by delivering tailored experiences to individual customer needs. Using data-driven insights to fine-tune offers and messaging makes interactions more relevant, strengthening brand loyalty. Combining behavioral, lifestyle, and transactional data provides a comprehensive understanding of the customer journey and ensures each touchpoint feels personal. Testing and iterating on personalization strategies also helps identify which data and approaches yield the best results. Scaling these efforts means customers receive the right messaging at the right time, and businesses see better outcomes. "Every business should be building a data strategy that thinks about the different versions of data that exist and how they bring that together. They don't necessarily need to own all of it but have a clear rationale and strategy about where you're using which data sets."Paul Frampton, CvE 4. Utilize advanced measurement tools for smarter decisions Improving the effectiveness of campaigns starts with using sophisticated measurement tools to gain actionable insights. Using analytics like brand lift studies, foot traffic analysis, app download tracking, incrementality, and share of search allows marketers to understand the full impact of their efforts. With these resources, teams can pinpoint what’s working, make real-time adjustments, and refine their approach. This adaptability ensures budgets are used as effectively as possible. Learn how Swiss Sense measured marketing outcomes using Mosaic® "We are playing a leading role in democratizing new tools for local advertisers. By mimicking the marketing funnel mentality, we've introduced solutions ranging from measuring brand lift to tracking foot traffic and app downloads."Luc Dumont, Madhive 5. Adapt quickly to stay competitive The only constant in advertising is change. Adapting quickly to new technologies and consumer behaviors keeps businesses competitive. A culture of agility fosters innovation, making it easier to respond to industry shifts and discover new opportunities. Companies that anticipate change and invest in modern data solutions position themselves for long-term growth. Whether it’s adjusting to privacy updates, exploring emerging tech, or staying flexible, businesses must continuously invest in adapting their platforms and strategies. "Falling behind is not really an option. There's always a change in advertising and in data where there's a new horizon. The people who stay close to that and innovate will always follow it."Amelia Waddington, Captify Shaping the future Building meaningful consumer connections requires advertisers to combine robust data strategies with flexibility and innovation. By focusing on these five considerations, marketers can adapt to today’s challenges while preparing for what’s ahead. Connect with our experts Latest posts
