What Is Server-Side Tracking?
Server-side tracking sends selected events from a server or backend system rather than relying entirely on code running in the visitor’s browser. It can make measurement more resilient, but it is not a license to ignore privacy or data quality.

Browser vs server
Browser events originate in the user’s browser. Server events originate from systems you control, such as your checkout, CRM or server-side tag setup.

Measurement is most useful when the team understands what the data includes, what it misses and which decision the metric is meant to support.

What to do next
Choose the next guide based on the decision you are trying to make. If your main problem is collection quality, start with server-side tracking.
