How Marketers are Using First-Party Data in TV Buys

As TV advertising shifts toward greater precision and accountability, marketers are increasingly leveraging their most valuable asset: first-party data. From email addresses and purchase histories to HIPAA-compliant patient records, brands are evolving beyond basic demographic targeting to launch data-driven linear and connected TV (CTV) campaigns that reach high-value audiences across all screens.

In this article, we'll examine how advertisers are using first-party data to transform their TV media buy and why it's revolutionary for modern marketers. We'll focus on three key advantages of audience-targeted TV: Precision Targeting Across Screens, Better Measurement and Attribution, and Enhanced Media Planning and Frequency Management.

What is First-Party Data and Why Does It Matter for TV?

First-party data is information a brand collects directly from its customers through owned channels and interactions. This includes:

• Email addresses
• Website and app engagement
• Purchase and transaction history
• Loyalty and rewards program participation
• CRM and customer support records
• Healthcare or patient data (with proper consent and HIPAA compliance)

First-party data's power lies in its accuracy and authenticity. Unlike modeled or third-party data, it comes directly from real customer behavior. In TV advertising, this data enables marketers to precisely target their highest-value audience even on traditionally mass-reach channels like linear TV. The result: more relevant ads, less wasted spend, and stronger viewer connections.

1. Precision Targeting Across Screens

TV advertising has evolved beyond broad, untargeted campaigns. Through secure data matching partners and clean room environments, advertisers can now align their customer data with set-top box and smart TV viewership data. This enables audience-based buying across both linear and connected TV environments.

Consider these real-world applications: A retailer can match its CRM list of high-value shoppers to households that frequently watch lifestyle networks. Similarly, a pharmaceutical company can target households likely managing specific conditions using de-identified patient data—all while maintaining HIPAA compliance and privacy standards.

This precision enables:

• Improved reach against key customer segments
• Reduced media waste
• Consistent messaging across linear and digital TV environments

Audience-targeted TV puts precision at the center of your media buys by ensuring that the viewers of your ad align with your specific customer segment. This is newer to TV but has been the main approach with digital. As streaming continues to grow, marketers can deliver their messages with unprecedented precision- reaching the right viewer, on the right screen, at the right moment, whether during live broadcasts or on-demand content.

2. Better Measurement and Attribution

Proving ROI has long been one of TV advertising's biggest challenges. First-party data is changing that by enabling marketers to tie TV exposure directly to business outcomes.

Through deterministic matching, advertisers can leverage CRM TV targeting by linking ad exposure to known users via hashed emails or device IDs brands. That also means, that they can leverage the same deterministic methods for TV measurement. They can now measure:

• Website visits after a TV ad airs
• In-store or online purchases influenced by a campaign
• Lift in key behaviors such as app downloads or form completions
• Phone calls for services
• New customer online sign ups

Leveraging first-party data for targeting and measurement allows advertisers a deterministic approach to not only reach the audience they were looking to target, but to understand the impact the data-driven TV and CTV campaigns have on their behaviors. Advertisers can also compare TV performance against digital channels, creating a unified view of the customer journey. This closed-loop measurement proves particularly valuable for performance-focused marketers who must justify every advertising dollar.

3. Enhanced Media Planning and Frequency Management

First-party data enables smarter cross-screen media planning. By understanding who has already purchased, visited a site, or seen an ad, marketers can:

• Avoid overexposing audiences who have already converted
• Allocate more budget to underexposed segments
• Coordinate messaging across channels for a cohesive brand experience

For example, a national brand can use its email list to exclude existing customers from broad TV buys while focusing on lookalike audiences. Additionally, by setting frequency caps across linear and CTV inventory against specific audiences built by their first-party data, advertisers can reduce wasted impressions and improve cost efficiency.

When marketers combine data-driven planning tools with predictive analytics, they can forecast and optimize media allocation impact bringing TV advertising to a level of sophistication previously seen only in digital. They are then able to take action on their cross-screen media planning to make it as effective and efficient as possible through data-driven strategies.

Key Takeaways

As privacy regulations tighten, first-party data has become the cornerstone of future-proof TV advertising. In fact, 77% of US marketing and advertising professionals already use first-party data as part of their solution. When leveraged strategically, it enables marketers to:

• Target specific audiences with personalized messages
• Measure results and optimize campaigns efficiently
• Generate measurable ROI from premium TV inventory

Whether you're investing in traditional linear spots or connected TV impressions, integrating your first-party data can transform TV advertising into a performance-driven channel that matches digital's effectiveness.
