Definition and Overview

Server-side tagging is a method of tracking and collecting data on user interactions with your digital assets by executing tags on a server rather than the user’s browser (client-side). In other words, server-side tagging shifts some of the data processing from the client-side to your own or third-party servers, providing you with increased control, security, and performance.

Benefits of Server-Side Tagging

Server-side tagging offers a multitude of advantages over client-side tagging. Let’s explore the main benefits that make it an essential tool in modern digital analytics and tracking:
