Server-Side Tagging
01 Definition
Server-Side Tagging meaning: Running tags on a server you control instead of only in the visitor's browser.
Server-side tagging sends data from the browser to a container running on your own server, which then forwards it to analytics and ad platforms. It can improve control over data, load fewer scripts in the browser, and help manage what information leaves your environment. It requires hosting and adds setup complexity.

Why it matters
How Server-Side Tagging fits the work
It gives more control over how tracking data is collected and shared, which matters as browsers restrict cookies and teams tighten data governance.
In context
A retailer moves its conversion tags to a server-side container, so purchase data passes through its own server before reaching the ad platform.
Practical note
Server-side tagging does not remove the need for consent, and running a server container adds hosting cost and maintenance. Misconfiguration can silently drop or duplicate data.
