Key takeaways
- First-party data records what happened inside one customer relationship. It can’t show the life stage, household makeup or financial pressure behind a purchase.
- Context earns its place in a customer record when it’s accurate, governed, and tied to a decision like segmentation, modeling or personalization.
- Governed context improves segmentation, prospecting, retention outreach and personalization by adding life stage, financial pressure and household signals.
- Experian maintains more than 5,000 consumer attributes, averaging roughly 250 per person, built with privacy and governance controls and grounded in durable identity.
A brand can have five years of purchase history, a loyalty program with millions of records, and a fully built-out customer data platform, and still not know why a customer walked away last quarter. First-party data has become one of the clearest ways brands can differentiate, which is exactly why it’s worth asking what more of it can and can’t do.
First-party data describes a relationship, not the whole person
A customer’s purchase history, site visits, app activity, and loyalty behavior are accurate records of what happened inside that one relationship. They don’t show who that person is beyond the transaction, the life stage, household makeup, or financial pressure that actually shapes a decision. Every brand runs into this limit eventually, no matter how much first-party data it has collected.
More sources isn’t the same question as better sources
The common response is to add more data sources. Third-party data, contextual signals, geographic data, each layered on to fill in what first-party data can’t see alone. Combining sources like this can expand what a brand can see.
It doesn’t automatically mean every layer earns its place in the customer record. Volume and quality are different questions, and only one of them is guaranteed by adding another source. A pile of attributes from unverified providers can sit alongside a brand’s best first-party and third-party data without ever being governed or relevant enough to act on with confidence.
Relevant, governed context is the differentiator, not another data source
Adding a new data type isn’t the same as adding context that’s actually relevant to the decision in front of you. A longer list of attributes doesn’t make a customer record more useful on its own, whatever source it came from. Context earns its place in that record when it’s accurate, tied to a real decision, like segmentation, modeling, or personalization, and usable within the governance standards a brand already holds itself to.

That’s a higher bar than volume. It’s also the one that actually changes outcomes. Predictive models and AI-driven decisioning only raise that bar. The more decisions get automated, the more they depend on inputs that are relevant, not just abundant.
What governed context actually changes
When a customer record includes real-world context, demographic, lifestyle, behavioral, and household signals that are built and governed responsibly, the decisions drawn from it change in specific ways.
- Segmentation reflects who people actually are, not just how they’ve transacted so far.
- Prospecting can find people who resemble a brand’s best customers in ways that matter, not just in surface-level behavior.
- Retention improves when outreach reflects a fuller picture of the person, not just their last transaction.
- Planning and personalization can account for the realities, like life stage or financial pressure, that shape whether a message lands.
That context is only as useful as the identity foundation underneath it. Context grounded in durable identity moves with a brand across the platforms, partners, and activation paths it already uses, rather than sitting locked inside one system.

At Experian, we maintain more than 5,000 consumer attributes, averaging roughly 250 per person, built and maintained with privacy and governance controls in mind. That depth creates the most value when it extends a brand’s own first-party foundation, grounded in identity and usable across the activation paths a brand already relies on, not locked into a single platform or vendor.
Context, not volume, is the differentiator
Owning first-party data was the starting point. It was never the finish line, and adding more sources on top of it isn’t the finish line either unless each one clears the same bar. The brands that get the most value out of their customer data in the next few years will know exactly what their data still can’t tell them, and will go find that missing context in a way they can trust and govern.
That’s the work I’d focus on, making the first-party data a brand already has tell a fuller, more accurate story about the people behind it, rather than acquiring more data for its own sake. If you want to talk through what that could look like for your first-party data, connect with our team.

As today’s digital landscape gets more and more complicated there are more ways for brands to connect with users and drive purchases and more ways for ad tech to target and measure those touch points. As in-person shopping picks up steam due to the re-normalization of society post-COVID 19; the connection between digital ads and in-person purchases needs to be made once again. With the rise of Connected TV throughout the pandemic there are even more digital opportunities to target a user. But how do you make sure that those brand engagements are captured and correctly attributed to offline purchases and conversions? The answer lies in a holistic identity resolution strategy. Cross-device identity resolution with The Tapad Graph connects the identifiers and devices of individuals within a household to each other; enabling targeting, frequency capping, extension, segmentation and measurement or attribution between devices; including Connected TV and hashed (privacy-protected) email addresses along with Cookies, Mobile Ad Ids and IP Address. Brands can join their first-party data to The Tapad Graph to execute strategies that connect online and offline data for pre, mid and post-campaign efficiencies. Let’s imagine a scenario in which an outdoor retail brand is targeting users watching specific content on a Connected TV device. Powered by identity resolution, they start with a general ad on CTV and continue targeting down individual paths with each user. When one of them converts in store and makes a purchase; the outdoor retailer can connect that action through location and in-store traffic data with the cross-device identity resolution used to execute the digital campaign. Now the actions of the user online and offline are resolved for more accurate measurement and attribution after the campaign ends. But it doesn’t stop there– the brand’s CRM data can be reactivated for the next digital campaign and leveraged to capitalize on the most effective media mix for the user who made the purchase previously. These combined insights can be invaluable in shaping up future campaign strategies with geo-contextual ads, recommended additional products and personalization to help drive more conversions and purchases in-store or online. As in-person shopping picks back up and marketers are tasked once again with balancing online and in-store KPIs, the right identity resolution strategy can unlock necessary efficiencies for retailers, ad tech vendors and agencies tasked with supporting these initiatives.

Experian Marketing Services and Data Quality President Genevieve Juillard recently sat down with Zach Rodgers, host of the AdExchanger Talks podcast to discuss the future of identity, the importance of data transparency and privacy, and our recent acquisition of Tapad. Genevieve focused on the opportunity for our industry to reimagine an advertising ecosystem that is resilient and adaptable; one that takes advantage of emerging data and prioritizes data transparency and consumer privacy. She also discussed the importance of advertising strategies that put consumers at the heart of every decision and give them more control over their data. Genevieve shared with AdExchanger that Experian’s acquisition of Tapad, a global leader in digital identity resolution, was a natural fit for our company. Tapad’s approach and role in the ecosystem is very much aligned with Experian’s, which is to develop solutions that are resilient to industry and consumer changes. The combination of our capabilities supports interoperability across all types of identifiers, both online and offline, and will position us to help our clients navigate the post-third-party cookie world.

It’s been over a year since Google announced they’d be deprecating the third-party cookie and in that time there’s been a major focus on two types of cookieless identity solutions. Identity vendors and marketers are strategizing which of these two future solutions best fits their needs so they can achieve privacy-safe scale once third-party cookies are no longer available for use on Chrome. Let’s break down these solutions and the considerations marketers need to take into account when deciding what partners to move forward with in the future of identity resolution. Authenticated Traffic Solutions Authenticated traffic solutions (ATS) are a type of digital identification that asks the end-user to identify themselves via personal information, most commonly email address. Often, you’ll see self-authentication at the point of entry to a website that asks you to create an account or login immediately to access the content you are seeking. E-commerce sites use authentication to keep track of consumer purchases and inform advertising decisions for that customer; and publishers use it to tailor featured content, or, more importantly for this discussion, leverage it within the ad ecosystem for targeting. While authentication can provide very valuable user data for audience segmenting and targeting, it can be limited in scale for a single publisher to leverage and monetize on their own. That’s why some identity vendors have worked to integrate themselves within as many publisher authentication modules as possible, so that they can create an aggregate of scale for the ad ecosystem to tap into. But, even this isn’t going to deliver the reach marketers truly thirst for. Alternatively, Facebook has the scale for authenticated traffic, but they keep their data inside a walled garden, so the utility of those authenticated users is only valuable within the Facebook ecosystem. So how can authenticated traffic solutions increase scale to broaden the scope of identifiers they can collect and leverage? Hint: a few of the biggest players have already figured it out. It’s the single sign-on. Google is probably the largest purveyor of a single-sign on solution that can directly impact advertising capabilities. Can you think of a site you visit that doesn’t offer a sign-in with your existing Google account? It’s a short list. Google has integrated themselves into so many applications and publishers that “Login with Gmail” is just second nature (you pictured the Gmail logo when you read that, didn’t you?). Now, if you’re about to purchase something you found off an Instagram ad, or perhaps a retailer you buy from regularly, you’ve probably noticed options to proceed with your checkout via “Amazon pay” or “Apple pay”. These are also single-sign ons. You’re authenticating yourself through Amazon or Apple to that retailer in exchange for A- the safety and security that Amazon or Apple provide for your financial information and B- skipping the annoying process of manually entering personal information over and over again at point of sale. It’s starting to sound like there’s a lot of authenticated data out there isn’t it? Well, that’s true, but again, Amazon and Apple are walled gardens. Amazon is working diligently to build out their own ecosystem to leverage their content and retail channel data for a holistic offering. And Apple keeps user data very close to the chest, constantly limiting its utility for themselves and advertisers. So what is identity resolution doing about it? The Trade Desk announced their solution; Unified ID 2.0, which promises to leverage email authenticated identity for a truly scaled solution for publishers via Javascript through Prebid. By handing over UID2.0 to an independent unbiased organization like Prebid, The Trade Desk is creating instant scale and trust in their solution. Unauthenticated Traffic Solutions Unlike ATS, unauthenticated traffic solutions do not rely on a log-in to identify a user, but they also don’t rely on third-party cookies. Instead, unauthenticated solutions (UATS) leverage their existing streams of real-time data through Javascript on publisher sites or an SDK (software development kit used by apps). The type of information UATS solutions can collect via Javascript or SDK vary, but it can include IP address, user agent and device level info. But being able to read this information at the point of entry to a website does not make a quality identifier. The best unauthenticated solutions will have the ability to set or ingest this information into a unique ID through an infrastructure with incredibly fast speed that can process trillions of anonymous data signals across multiple channels and devices. And even more so, be able to interpret those signals into a profile using machine learning– all at the moment a user enters a domain. It sounds complicated because it is, but it also has a lot of potential. The identity space cannot rest solely on authenticated traffic solutions, because, as you can see, it could limit ownership and operability to just a few power players/walled gardens. This doesn’t help the larger ecosystem monetize and personalize ad inventory. The right unauthenticated solution, however, can unify cross-device individuals and households at scale, because they’re integrated on the broadest number of publishers/SDKs across platforms, have the best algorithms to build confident connections between identifiers, and are universally transactable across the most common sell and demand side platforms. Think of it as the perfect partner- speaking a common language that everyone in the ecosystem understands and acts on. Today more than twenty cookieless identifiers are available in market for the ad ecosystem, and Google hasn’t even announced a date of deprecation. It’s important to be on the lookout for differentiators like scale and precision. Most importantly, choosing a truly cross-device partner will be key, especially as more digital devices and IDs grow in adoption, like CTV has this past year. Taking advantage of both What we will come to find, once the third-party cookie is obsolete, is that choosing just one of these solution types, or partners, will be a disadvantage. The more the industry comes together to collaborate on solutions, the more apparent it is that both of them have value, and thus employing both solutions will give marketers the best opportunities. Tapad, now part of Experian, recently announced the launch of Switchboard; a module within our identity solution; The Tapad Graph, to create this agnostic interoperability for identifiers of all types, and choice and control for the ad tech vendors and marketers who want them. By instantly creating the ability to partner with multiple solutions, Tapad + Experian is ensuring that all use cases for the third-party cookie live on in our cookieless future. Get in touch
