Introduction

Privacy regulations and cookie restrictions have led to new methods of data measurement. Server-side tracking and data clean rooms are two key approaches. Understanding their differences helps marketers choose the right solution for privacy-first, accurate analytics.

What is Server-Side Tracking?

• Direct Event Capture: Data collected directly from your server instead of the user’s browser.
  
  

• Cross-Platform: Integrates web, mobile, and app interactions.
  
  

• Privacy Compliant: Data is hashed or anonymized to meet GDPR/CCPA standards.
  
  

• Real-Time Analytics: Enables immediate processing for personalization and attribution.

What is a Data Clean Room?

• Secure Environment: Aggregates data from multiple sources without exposing raw user data.
  
  

• Privacy-Centric: No personally identifiable information (PII) leaves the clean room.
  
  

• Collaboration-Friendly: Brands and partners can analyze joint datasets securely.
  
  

• Aggregated Insights: Provides trends, correlations, and attribution insights without tracking individual users.
