Improved data security: Server-side tracking keeps sensitive data, such as user IDs and purchase values, secure on your servers, away from browser-based vulnerabilities.
Greater control over tracking: Server-side tracking provides you with full control over data storage and processing, allowing for seamless integration with your internal analytics and monitoring systems.
