The Post-Cookie Pharma Playbook: First-Party Data Strategies for 2025

The pharmaceutical industry is facing a seismic shift. With Google’s planned phase-out of third-party cookies in 2025, pharma marketers who’ve relied on traditional tracking methods find themselves at a crossroads. But here’s what industry leaders like UCB have discovered: this isn’t a crisis—it’s an opportunity to build something better. Jennifer T, Head of Omnichannel and Digital Marketing at UCB, recently shared their journey: “We’ve been on a digital business transformation journey for the last five years, and a piece of that is internalizing all of our data, having first-party data.” The result? A more sustainable, privacy-compliant approach to HCP engagement that delivers better results.

Why First-Party Data Matters More Than Ever

The average pharmaceutical company interacts with healthcare professionals through 15+ touchpoints before they write their first prescription. Without cookies, tracking this journey becomes impossible unless you own the data. First-party data isn’t just about compliance—it’s about creating meaningful HCP relationships. The key advantage? You control the data, you control the relationship. No more relying on third-party platforms that change algorithms or policies overnight.

1. The UCB Playbook: Start with Data Stewardship

When UCB began their transformation, they made a critical discovery: “I inherited a ton of data and technology… what are we actually going to do with it? Do we need all of this data? What’s the data’s utility?” Jennifer admits. The first step wasn’t collecting more data—it was cleaning what they had. Implementation Strategy:

• Audit Existing Data: Map every data point to a specific business KPI
• Establish Data Stewardship: Create roles responsible for data quality and accuracy
• Implement Consistent Formatting: Bridge the gap between agency data and internal systems
• Focus on Utility: If data doesn’t inform decisions or improve customer experience, remove it UCB’s Approach: They developed a “clean data” standard where data must be able to inform the next decision. As Jennifer puts it, “Clean data is data that can inform your next decision.”

2. Build Your Data Foundation Before You Need It

Here’s what most pharma companies get wrong: they wait until the crisis hits to start building their first-party data strategy. UCB started five years ago, and they’re still refining their approach. Critical Components:

• Tag Everything: Ensure all websites and media channels are properly tagged
• Connect the Dots: Link HCP engagement across all touchpoints
• Master HCP Data: Create unified profiles that track the complete journey
• Implement Real-Time Processing: Weekly data feeds are the minimum for effective targeting The Technology Stack: UCB uses ZS for algorithm development but is working to internalize their engine into their data warehouse, creating a true Customer Data Platform (CDP) built for pharma’s unique needs.

3. Evolve Beyond Traditional KPIs

Traditional metrics like impressions and click-through rates don’t tell the full story in a post-cookie world. UCB discovered their definition of “digitally engaged HCP” was fundamentally flawed. Old KPI: An HCP who opened an email, clicked it, and took website action New Reality: An HCP who opens an email and gets all needed information without clicking is still successfully engaged Jennifer’s Insight: “I have a crazy idea… what if somebody opens an email and it has all the content that they want and they don’t need to click. So they had to do all of those things to be digitally engaged? Give me some credit where credit is due.”

4. Focus on Next Best Action (NBA)

UCB’s approach to personalization centers on understanding HCP preferences and delivering the right next step: Real Examples:

• An HCP who engages with cardiology content receives cardiology-focused emails
• Post-sales rep conversation triggers targeted banner ads
• Real-time algorithmic decisions optimize content delivery
• Weekly data feeds inform targeting decisions The results speak for themselves: “Significantly higher engagement” through real-time, algorithmic content optimization that respects HCP preferences while maintaining compliance.

5. Create Sustainable Internal Capabilities

Here’s the challenge UCB faced: agencies were spending hours manually formatting data for internal requirements. Their solution? Technology that automates the process internally. Building Internal Excellence:

• Automate Data Processing: Remove manual Excel-based data manipulation
• Develop Internal Talent: Transition teams from HTML coding to quality assurance
• Create Standardized Processes: Ensure consistent data handling across markets
• Invest in Tools: Use technology to scale without proportional cost increases

The Compliance Advantage

First-party data isn’t just better for marketing—it’s better for compliance. With complete control over your data:

• Consent Management: Clear, documented opt-in processes
• Data Minimization: Only collect what you need and use
• Purpose Limitation: Use data only for stated purposes
• Audit Trails: Complete visibility into data usage

The Bottom Line

The cookie-less future isn’t coming—it’s here. Pharma companies that act now to build first-party data capabilities will thrive. Those that don’t will find themselves increasingly dependent on third-party platforms they can’t control. As Jennifer from UCB discovered, the key isn’t having more data—it’s having the right data, used in the right way, to create meaningful HCP relationships that last.
