Server-Side Event Tracking: What Changes and What Does Not

Server-side event tracking is often presented as a fix for every measurement problem. It solves several of them well, leaves others untouched, and introduces a set of operational questions that a business needs to answer before switching anything over.
What it genuinely improves
Sending events from your own server rather than from the browser reduces the effect of browser restrictions, ad blockers and slow page loads on event capture. For advertisers whose conversions happen after several page views, this can recover a meaningful share of missed events.
What it does not change
Server-side tracking does not resolve attribution overlap between platforms, does not reconcile platform-reported conversions with settled orders, and does not create a source of truth where none exists. Those are modelling and process questions, and they remain open.
Consent still governs what may be sent
Moving the event to the server does not remove the need for a lawful basis for processing. Consent handling, data minimisation and retention rules apply to server-side events in exactly the same way, and the implementation should make it straightforward to honour a withdrawal.
Plan the fallback
Run browser and server tracking in parallel for a period and compare captured volumes before switching over. The comparison is the evidence that the migration worked, and it is also the fallback if the server path fails during a peak period.
Document the event contract
Write down every event name, its required parameters and who owns it. Server-side tracking introduces more places for a naming inconsistency to hide, and a written contract is the cheapest way to prevent it.
