Server-side tracking 101 — what it is and why you need it
An explanation of the difference between client-side and server-side tracking. Why ITP, ad-blockers, and iCloud Private Relay eat 25-40% of your conversions — and how server-side gives you clean data back.
What are UTM parameters and how to use them correctly
UTM parameters are tags in a URL that let analytics know where a visit came from. What each one means and how to use them consistently.
What are fbp and fbc: the cookies Meta attribution rests on
fbp and fbc are two cookies Meta uses to match conversions to users and ads. What each means, where they come from and why to send them via the Conversions API too.
What are modeled conversions
A modeled conversion is a statistical estimate of conversions that can't be measured directly — typically because consent was declined. How it arises, where you'll meet it and how to read it.
What is GCLID and click IDs (and why they matter)
GCLID, fbclid and other click IDs are ad-click identifiers. They tie a conversion to a specific ad and enable offline conversions. How they work and how not to lose them.
What is a Conversions API and which platforms have one
A Conversions API is the general idea of sending conversions to an ad platform directly from the server. How it differs from the pixel, why it exists and which platforms offer one.
What is a first-party domain for server-side GTM (and why it matters)
The server-side GTM container runs on your own (sub)domain, not a third party's. What that means, why it makes cookies last longer, and how it relates to a CNAME record.
What is an attribution window
An attribution window is the time within which a conversion still gets credited to an ad click or view. Why it matters and why it makes numbers differ between platforms.
What is client_id and user_id in GA4
client_id and user_id are two identifiers GA4 uses to know whom events belong to. How they differ, why they're crucial for server-side and when to use which.
What is conversion rate and how to calculate it correctly
Conversion rate is the share of visitors who took a desired action. It sounds simple but is easily miscalculated — and patchy measurement skews it. How to read it correctly.
What is data retention in GA4
GA4 keeps detailed data only for a limited time (2 or 14 months). What that means for your analyses, what it applies to and how to secure a longer history.
What is hashing and why personal data is hashed before sending
Before an email or phone goes to an ad platform, it's hashed. What hashing is, why it enables matching without revealing data, and what to watch with normalization.
What is the Measurement Protocol (GA4)
The Measurement Protocol is the interface server-side GTM uses to send events to Google Analytics 4 directly from the server. How it works, what it needs and its limits.
iOS ITP + iCloud Private Relay — what you actually lose and how to get it back
iOS 17 + Private Relay anonymizes 30-40% of your traffic. When it can be recovered with server-side tracking and when it can't.
