First-party data for commerce media networks (CMNs) provides a direct connection to shopper behavior that advertisers value. But logged-in users and loyalty members only tell part of the story. Connecting fragmented identities and adding context beyond the observed behaviors can help CMNs turn more of the data they already own into consumer intelligence that works across media channels, while keeping their customer relationships at the center.Key takeaways
- First-party data can leave coverage gaps between the shoppers a CMN knows and the audiences it can consistently recognize and reach.
- Experian’s identity resolution and enrichment solutions help commerce media networks connect fragmented signals and add context beyond the direct customer relationship.
- CMNs can focus on closing their first-party data gaps and building a more complete view of their consumers. Our neutral approach helps them activate and measure campaigns across platforms without building separate integrations for every partner, while giving them the flexibility to work with their preferred technology and media partners.
Owning first-party data gives CMNs a strong foundation. The next step is connecting shopper data across customer relationship management (CRM), digital, and TV. Identity resolution helps CMNs link interactions across channels so they can recognize and reach consumers more consistently.
Media networks know what people browse and buy, loyalty programs create direct customer relationships, and transaction data gives advertisers a valuable connection between media and commerce. But logged-in and loyalty data rarely represent every shopper interaction. CMNs need to connect these signals to build a more complete view of their consumers and put that insight into action.

A shopper might research a product anonymously on mobile, buy it in-store without using a loyalty account, and then return using a different email address. By connecting these interactions, CMNs can build a more complete view of their consumers and better understand how shoppers engage across channels.
Multiply that across millions of interactions, and the challenge grows. Guest transactions can sit outside loyalty profiles, identifiers change, and shoppers move between stores, websites, apps, and devices. A CMN may have plenty of first-party data and still see only part of its audience.
The addressability gap starts inside the data
CMNs face an addressability gap when disconnected shopper data limits their ability to recognize and reach consumers beyond their own properties. Connecting loyalty profiles, transactions, and digital identifiers helps CMNs extend their reach across connected TV (CTV), social, and programmatic media.
Market concentration makes that challenge more pressing. Amazon and Walmart will capture more than 81% of U.S. off-site retail media ad spending in 2027. Their large logged-in audiences and extensive commerce data give them an advantage. Other CMNs can compete by making better use of the shopper data they already have.

Identity resolution helps CMNs close the addressability gap by connecting logins, devices, email addresses, and transactions to consistent consumer and household identities. This helps CMNs recognize shoppers across channels and reach more of their audience.
Our neutral infrastructure helps CMNs use that identity foundation across their preferred technology and media partners. They can build on existing investments, strengthen cross-platform addressability, and maintain flexibility without relying on a single provider.
A transaction tells you what happened, not the whole story
CMNs can build more valuable audiences for advertisers by enriching their first-party shopper data with deeper consumer insights. This helps them improve audience segmentation, strengthen their advertising offerings, and create more opportunities to generate revenue.
Purchase data reveals what shoppers buy, but it doesn’t always explain who they are or what else matters to them. A retailer may know that someone buys organic groceries every week or recently purchased paint and power tools. Two shoppers who bought the same product may represent very different audiences for advertisers.

Experian’s Enrichment capabilities help CMNs look beyond transactions by appending demographic and behavioral attributes from Experian Marketing Data to their first-party shopper data. These additional insights help CMNs refine segmentation, inform modeling, and create more relevant audiences for advertisers. With richer consumer insights, CMNs can turn transaction data into more valuable advertising offerings, helping them create new revenue opportunities while maintaining their direct shopper relationships.
Keep first-party data connected across media
CMNs can get more value from their first-party data by keeping consumer identities and audience definitions consistent across media channels. Connecting shopper signals and adding consumer context helps them build audiences they can activate, collaborate with advertisers, and measure across platforms.
Keeping audiences consistent across media channels can be challenging as CMNs move between platforms and partners. Audiences can lose scale when they reach another environment, and differences in how partners recognize consumers can create gaps in activation and measurement.
Our neutral infrastructure helps CMNs keep their first-party data connected across their preferred technology and media partners. They can maintain control over their data and identity, build on existing investments, and avoid relying on a single provider.
Experian helps CMNs strengthen their first-party data foundation for use across existing systems and media channels. With our identity resolution and offline identity append capabilities, CMNs can share first-party data with us to connect disparate records to individuals and households and add missing offline identifiers. We then return the data so CMNs can use it across their existing systems and preferred partners.
By keeping first-party data connected across media, CMNs can extend the value of their shopper relationships, support advertiser campaigns, and make better use of their existing technology investments.
More addressable data creates more places to grow
Connecting shopper data across media helps CMNs expand their addressable audiences and create more advertising opportunities.
A more complete, addressable audience can give advertisers more ways to use first-party data that makes a CMN distinct. It can help networks extend those audiences beyond owned-and-operated properties into CTV, social, programmatic, and other environments where shoppers spend their time.
CMNs can build on their existing technology investments by improving the quality and consistency of their first-party data. With a stronger identity foundation, they can better understand their customers, activate audiences across channels, and measure campaign outcomes.
CMNs can strengthen their advertising offerings by turning more of their existing shopper data into audiences advertisers can reach across channels. By recognizing more consumers across channels and building more relevant audiences, they can create additional media opportunities for advertisers while keeping their first-party data at the center of their business.
Our neutral infrastructure helps CMNs extend the value of their first-party data across media environments while maintaining control over their customer relationships, technology investments, and partner choices.

FAQs
The first-party data gap for CMNs is the difference between the shopper data a CMN owns and the first-party data it can consistently connect and use. Anonymous interactions, disconnected identifiers, and incomplete customer records can leave part of the shopper relationship outside a CMN’s addressable audience.
CMNs can use identity resolution to connect fragmented shopper signals and enrichment to add relevant context beyond the direct customer relationship. Neutral infrastructure helps them put that consumer intelligence to work across activation and measurement, using their existing technology and preferred partners to extend reach and improve outcomes.
Neutral infrastructure gives CMNs greater control over how they use their customer data and identity across platforms, partners, and channels.

Advertisers continue to increase their spending across addressable TV, connected TV (CTV), and digital. According to IAB’s “2021 Video Ad Spend and 2022 Outlook” report, digital video ad spending is expected to increase by 26% to $49.2 billion in 2022. Understanding who consumers are and how to best reach them in their preferred channel is becoming more complex. Damian Amitin and Colleen Dawe discuss how a seamless identity strategy can address the complexity of the emerging TV space. The evolution of identity resolution Around ten years ago, the idea of digital “identity resolution” or “Device Graphs” was born. This idea connected cookies and MAIDs to understand when many IDs were the same person or household. In more recent years, our industry began to connect that initial understanding to the CTV ecosystem. But, a large part of the TV ecosystem existed in silos, like first and third-party audience data, and the growing advanced TV market. The goal of identity resolution has always been to understand the consumer better. To achieve more accurate targeting and measurement in the CTV ecosystem, we must incorporate the following: What we know about the household and consumer from an ID perspective Who the consumer is as it relates to audience data, as well as the wealth of first-party data in the advanced TV space We know the cookie is a flawed way to collect data. While Google delayed the deprecation of third-party cookies, there are other challenges that we face right now. Such as the glaring gap in Safari traffic and the Identifier for Advertisers (IDFA) turning to “opt-in.” Understanding consumer behavior across devices and platforms continues to challenge marketers and publishers. These challenges are creating the need to find more stable identifiers. Though the cookie remains valuable, it has an uncertain future. This has led advertisers to place bigger bets on the combination of addressable and CTV. The overlap in addressable and CTV data leads to fragmentation Personally identifiable information (PII) makes up the majority of addressable TV households’ data. Part of the attraction to CTV is that their IDs remain universal, persistent, and stable. Analysts project that CTV ad spending will hit $23B in 2023. Consumers now have an average of 4.7 streaming subscriptions per household. It’s no surprise then, that Disney+, HBO, and Netflix released or announced ad-supported tiers. Addressable TV and CTV are often thought of as distinct markets across the industry. But, in the context of identity, we should look at them through the same lens. Millions of households still consume TV and video content via a set-top box or through apps on CTVs. This is in addition to what they consume on their laptops, tablets, and phones. Of the top 11 cable and satellite providers, 65 million U.S. households still have a box in their homes. On the other hand, approximately 96 million U.S. households have at least one or more Smart TVs and streaming services. With about 126 million total U.S. TV households, that’s a lot of overlap. There are still significant numbers of both addressable and CTV homes. How can we address fragmented TV consumption? Through a holistic and comprehensive approach to identity. An approach that captures addressable TV, CTV, and digital identifiers. An approach that captures all audience attributes inside of a single identity graph. This is the ideal approach for publishers, AdTech vendors, and brands. Discover how to unlock holistic identity How can we achieve a holistic identity? Through a three-pillared approach: First-party data onboarding Digital identifiers Consumer data First-party data onboarding Bringing offline data from a brand’s consumers is very valuable due to the quality of the data. Because the data is being collected right from the source, you know it’s accurate. It provides the foundation you can build your identity strategy from. Digital identifiers Once you create a foundation with first-party data, you need to connect it. Either with an internal or licensed digital ID graph. Then you can understand the connections between all devices within the household. Consumer data After you know which devices tie to a single consumer, you’ll want to act on that knowledge. The next step is to partner with a data provider that can help you understand your consumers. Establishing this partnership will help improve targeting, measurement, and the customer experience. To achieve a well-rounded customer view tomorrow, we need to start today The three-pillared approach bridges the gap between the offline and online worlds. This provides a well-rounded view of customers and audiences. However, the ability to tie these aspects of identity together still presents several challenges. To achieve the three-pillared approach today, you need to use many vendors and fragmented data sources. Often with conflicting data. As we look forward, the tools to do this are becoming more advanced and unified. The players in our ecosystem should adopt a seamless identity strategy. One that provides a privacy-safe yet full-picture solution. That means capturing and unifying all devices within a household. While also understanding the consumer behaviors and profiles behind those devices. Keep up with your customers and their data Once we create an informed identity strategy, we can begin to understand the makeup of each household and the individuals within. In this new world, personalizing the experience for an audience is key. Where do they prefer to spend their time? What type of content are they most engaged in? Only then can we as an industry provide an optimal experience for each consumer. All while driving greater ROI for advertisers and publishers.

Next up in our Ask the Expert series, we hear from Sarah Ilie and Lauren Portell. Sarah and Lauren talk about the internet’s value exchange – what we gain and lose when it’s so easy to share our information. Is convenience hurting or helping us? The age of connectivity Today, it’s almost unimaginable to think about how your day-to-day life would look without the convenience of the internet, smartphones, apps, and fitness trackers; the list goes on and on. We live in the age of connectivity. We have the convenience to buy products delivered to our homes on the same day. We can consume content across thousands of platforms. We also have watches or apps that track our health with more granularity than ever before. The internet’s value exchange In exchange for this convenience and information, we must share various kinds of data for these transactions and activities to take place. Websites and apps give you the option to “opt in” and share your data. They also often let you know that they are collecting your data. This can feel like an uncomfortable proposition and an invasion of privacy to many people. What does it mean to opt-in to a website or app’s tracking cookies? What value do we exchange? What opting in means for you Opting in to cookies means that you are allowing the app or website to track your online activity and collect anonymous data that is aggregated for marketing analytics. The data provides valuable information to understand users better to create better online experiences or offer more useful products and content. Granting access to “tracking” offers several benefits to users such as a customized, more personal user experience or advertising that is more likely to be relevant. For example, let’s imagine you have recently been using an app or website to plan a camping trip. By sharing your data, the website or app has visibility into what is interesting or useful to you which can lead to related content suggestions (best campsites) or relevant advertising and product recommendations (tents and camping equipment). It’s important to know that the marketing data collected when you opt in is extremely valuable. The revenue that advertising generates is often very important to websites and apps because this is how they make money to continue providing content and services to consumers. Data privacy practices Privacy concerns regarding how companies and developers use tracking information have risen over the last couple of years and have resulted in additional protection for consumers’ privacy while still allowing companies to improve their products and advertising. One big step in this direction has been simply making people aware that their data is being collected, why it’s being collected, and providing users with the option to share this data for marketing analytics through opting-in or not. Other important steps to maintain online privacy include formal legal legislation and self-regulation. The right to privacy is protected by more than 600 laws between individual states and federal legislation and the U.S. House Committee on Energy and Commerce recently voted to pass the American Data Privacy and Protection Act. Additionally, marketing organizations such as the Interactive Advertising Bureau and Association of National Advertisers regulate themselves with codes of conduct and standards given there is so much attention on privacy issues. Is the internet’s value exchange worth it? The data that we choose to share by opting in has a lot of benefits for us as consumers. There are laws in place to protect our data and privacy. Of course, it’s important to be aware that data is collected and used for marketing purposes, but it’s also reasonable to share a certain amount of data that translates into benefits for you as well. The best data unlocks the best marketing. Contact us to tap into the power of the world’s largest consumer database.
