Harm Luijkx

Tracking specialist @ tagbrains

This is how we setup tracking for 1 new domain in 20 minutes

Setting up tracking for multiple domains can be very time consuming.


# How do we tackle this?

Multi-domain setups from 1 web and server container.


# How to set it up?

Use RegEx variables for all ID's needed

{{Page Hostname}} in web container with pattern; .*example.com.*

{{Page Location (event data)}} in server container with pattern; .*example.com.*


# How do we spend the 20 minutes?

1. Make sure the same web container is loaded in on the new domain
2. Setup datalayer plugin / custom pixel
3. Create new Google Ads conversions, GA4 property, etc.
4. Retrieve all needed ID’s from accounts
5. Add the new id + new domain pattern in existing RegEx
6. Test → Done !

p.s. Make it easy for yourself and create a folder where you can easily access all RegEx variables that need to be edited.

SST ≠ First-Party Mode.

Stop mixing them up.

Let’s break it down:

---

First-Party Mode:

↳ Sets cookies from your own domain (NOT subdomain) - "same-origin".
↳ This bypasses ITP's impact on cookie lifetimes (Safari, Firefox).
↳ Because of this, conversion attribution will be better.


SST:

↳ Send hits to your own server first - you control the data.
↳ Helps bypass ad blockers looking for the GTM code.
↳ Because of this, the amount of data will be higher.


First-Party Mode = how cookies behave.
SST = how data moves.

---

One doesn't replace the other.

Combining SST and First-Party Mode ensures the best possible tracking and analytics setup within the 'Google Marketing Platform stack'.

P.S. I know the above is a simplification of this technology, but I wanted to make it digestible for the average marketer.
