What is Server-Side GTM?

Server-side GTM shifts tracking logic from the user’s browser to a server you control. This approach:

• Reduces data loss due to ad blockers or cookie restrictions.
  
  

• Protects sensitive user data in a controlled environment.
  
  

• Integrates seamlessly with platforms like GA4, Facebook, TikTok, and LinkedIn.

Benefits of Server-Side GTM

1. Enhanced Privacy: Keeps user data on your server, reducing exposure to third-party scripts.
   
   

2. Better Data Accuracy: Server-side events are less likely to be blocked or lost.
   
   

3. Cross-Platform Tracking: Unified measurement across web and mobile apps.
   
   

4. Improved Page Performance: Offloads tracking scripts from the browser, speeding up page load times.
