Each method has trade-offs in terms of data accuracy, control, and resistance to blockers.

Client-Side Tracking:

• Captures rich, real-time interactions in the browser or app.
• Susceptible to ad blockers and privacy settings.
• Commonly uses the Snowplow JavaScript tracker.
  
  

Server-Side Tracking:

• Sends data directly from backend services—more reliable and less prone to loss.
• Ideal for environments where client-side JS can’t be trusted.
• Supported by Snowplow’s server-side trackers for web and mobile.
  
  

Tip: A hybrid approach often provides the most comprehensive insights.
