Server-Side Tracking
Moving measurement off the browser: a server-side container, platform conversion APIs, and control over what data leaves your infrastructure.
Overview
Browser-based tracking has been eroding for years. Ad blockers remove a share of it, browsers cap the lifetime of cookies set by scripts, and every operating system update tends to remove a little more. Sites now lose a substantial portion of measurable events before anything reaches the analytics.
Server-side collection moves the work to your own infrastructure. Events go to your endpoint and from there to the platforms, which recovers a good deal of what the browser loses, improves page speed, and puts you in control of exactly what data is forwarded.
Who this is for
- Advertisers whose reported conversions dropped without sales dropping
- Companies wanting control over what is sent to advertising platforms
- Teams whose pages are slowed by a long list of third-party tags
How we approach server-side tracking
The specific pieces of work a typical engagement covers. Scope is agreed up front — nothing here is a surprise line item later.
Server-side container
A tagging server on your own domain and infrastructure, which is what makes the rest of this possible.
Conversion API integrations
Direct server-to-server connections to the advertising platforms, with event deduplication against the browser events.
First-party cookie handling
Identifiers set server-side, which are not subject to the short expiry browsers now apply to script-set cookies.
Data filtering
Deciding exactly what is forwarded to each platform. Sending less than the default is both a privacy improvement and usually a sensible one.
Consent enforcement
Consent state respected at the server, so it cannot be bypassed by a misconfigured client-side tag.
Page speed improvement
Fewer third-party scripts in the browser, which is often a noticeable performance gain on its own.
From first call to measured result
The same sequence every time, so you always know what happens next.
Measure the loss
Quantify what is currently missing by comparing browser-reported events against your own back-end records.
Build
Stand up the server-side container on your domain and configure the event pipeline.
Connect
Integrate platform conversion APIs with deduplication, then verify counts against source records.
Migrate and monitor
Move tags off the browser progressively, monitoring for gaps at each step rather than switching everything at once.
Outcomes, not deliverables
A pile of artefacts isn't progress. These are the changes the work is meant to produce — and what we report against.
Conversions that get counted
Server-side collection recovers a meaningful share of events lost to blockers and browser restrictions.
Better bidding
More complete conversion signal directly improves how well automated bidding performs.
Faster pages
Removing third-party scripts from the browser improves both experience and Core Web Vitals.
Control over what you send
You decide what data reaches each platform rather than accepting whatever their tag collects.
Common questions about Server-Side Tracking
The things people ask before they get in touch. If yours is not here, ask us directly.
How much conversion data does server-side tracking recover?
It depends heavily on your audience's use of blockers and browsers, and the answer for your site comes from comparing browser-reported events against your own order records. The recovery is usually large enough to change bidding performance, which is the main commercial argument for doing it.
Does this get around ad blockers?
It is more accurate to say it moves collection somewhere blockers do not operate. It is not a way to track people who have refused consent, and it should never be configured to do that. Consent still governs what may be collected.
What does it cost to run?
A server-side container has ongoing infrastructure cost that scales with traffic, typically modest relative to media spend. For a small site the cost may not be justified; for anyone spending meaningfully on advertising it usually pays for itself through bidding performance alone.
Is it difficult to maintain?
More involved than browser tagging. It is real infrastructure that needs monitoring and updating, so it should be part of a maintenance arrangement rather than set up once and forgotten.
