Why Do We Need Server-Side Tagging?
In digital marketing, keeping track of user interactions with ads and measuring campaign success is crucial. Traditionally, marketers have used tools like Google Tag Manager (GTM) to facilitate tracking. However, this approach has several limitations.
Firstly, many web browsers are beginning to block third-party cookies, making accurate data collection more difficult.
Secondly, server-side tagging operates on a subdomain, making it harder for ad-blockers to detect and increasing ad effectiveness.
Thus, marketers are adopting server-side tagging for more reliable and accurate tracking.
How Does Client-Side Tagging Work?
When running campaigns, marketers often integrate code snippets or pixels from marketing platforms into their websites. This establishes a direct communication channel between users' web browsers and third-party vendors, enabling conversion tracking and traffic analysis.
However, client-side tagging has drawbacks. Third-party vendors may collect additional user data through third-party cookies, which can pose privacy concerns without the user's awareness.
How Does Server-Side Tagging Work?
The server acts as an intermediary between the user’s browser and marketing platforms, eliminating the need for direct communication between the browser and third-party vendors.
With server-side tracking, reliance on third-party cookies and client-side JavaScript libraries—which can slow down websites—is reduced. Instead, cookies are set from the cloud tagging server URL, which is aligned with the main website domain.
