Conversion Tracking.
The plumbing behind every report: how to set up Google Tag Manager, events, UTMs and server-side tracking so your data is actually trustworthy.
Every dashboard, every attribution model and every ad platform runs on one thing: whether the conversion was tracked correctly in the first place.
Tracking is the unglamorous layer nobody wants to own, and it's where most reporting quietly breaks. Double-counted conversions, untagged campaigns, events that silently stopped firing — bad tracking poisons everything downstream.
This hub is the plumbing: install tags cleanly through GTM, fire the right events, tag campaigns with UTMs, and move server-side when the browser isn't enough. It sits under our marketing analytics guide and feeds attribution — you can't credit a touchpoint you never captured.
Inside Tracking
Six parts of a tracking setup.
Trustworthy data is a stack of small, careful pieces. Each one below has a deep-dive underneath it.
Google Tag Manager
Install and organize every tag from one container — the maintainable way to manage tracking without touching site code.
Explore →Event Tracking
Fire the custom events that represent real actions — and mark the ones that matter as conversions in GA4.
Explore →UTM Tracking
Tag every campaign link so traffic lands in the right channel — the naming conventions that keep reports clean.
Explore →Server-Side Tracking
Route events through your own server for accuracy and resilience against ad blockers and cookie limits.
Explore →Cross-Platform Measurement
Deduplicate conversions across Google, Meta and your CRM so one action isn't counted three times.
Explore →GA4 Integration
Where tracking lands — connecting your tags and events to GA4 so the numbers show up where you report them.

How to set up tracking you can trust.
Reliable data isn't luck. It's three habits that most setups skip and then regret.
Plan before you tag
Write down the actions worth tracking and name them consistently before you build anything. A tagging plan prevents the mess that's impossible to untangle later.
Deploy through one layer
Run everything through a tag manager and a data layer so changes happen in one place. Scattered hard-coded tags are how tracking silently rots.
Test before you trust
Verify every event in preview mode and watch for duplicates before a number reaches a report. Untested tracking is worse than none — it looks real.

Questions
Tracking, answered.
What is conversion tracking?
Conversion tracking is the plumbing that records when someone completes a meaningful action — a form submit, a purchase, a call — and attributes it to the source that drove it. It's the raw data every report, attribution model and ad platform depends on.
What's the difference between conversion tracking and attribution?
Tracking is capturing the event — did a conversion happen and where did the visitor come from. Attribution is deciding how to split the credit for it across touchpoints. Tracking is the plumbing; attribution is the accounting that runs on top.
Do I need Google Tag Manager for conversion tracking?
You don't strictly need it, but GTM is how most teams manage tracking without editing site code for every change. It lets you deploy and update tags, triggers and the data layer from one place, which keeps a growing tracking setup maintainable.
What is server-side tracking?
Server-side tracking sends event data through your own server before it reaches analytics and ad platforms, instead of relying only on the browser. It improves data accuracy and resilience against ad blockers and cookie restrictions, at the cost of more setup.
Why are my conversions tracked more than once?
Usually a trigger fires on every page load or a tag is installed twice. Clean conversion tracking means one event per real action, deduplicated across platforms — which is why testing in preview mode before you trust the numbers matters.
