Tracking
A tracking setup you can base decisions on
I clean up GA4, Google Tag Manager, consent mode and server-side tracking. The setup is checked against real events or orders, so you know what the numbers can be used for.

The technical help I cannot do without
I would never be able to serve my clients as well as I do without Mikkel.

Warning: work with Mikkel and you risk damaging your relationship with every other supplier you have. It happens because he sets, by nature, an extraordinary standard for flexibility, decency and not least delivery time.

Tracking
Browser blocking of third-party cookies makes classic tracking leakier every year. The answer is moving measurement to your own domain with a server-side GTM container, so you measure the visitors who gave consent without losing them to adblockers and intelligent tracking prevention.
The work typically covers setting up Google Tag Manager server-side, migrating to GA4, consent mode v2, enhanced conversions for Google Ads, the Meta Conversions API and data layers on webshops. I also debug existing setups where conversions are counted twice or not at all.
The biggest value goes to webshops and companies spending real money on advertising and making decisions from the numbers. I take consent seriously: the goal is accurate numbers for the visitors who said yes, and a setup your lawyers can stand behind.
Geography matters little in this kind of work, and I have tracking clients in Copenhagen, Aarhus, Odense and Aalborg as well as a few abroad. Everything can be handled remotely with shared access to GTM, Analytics and the ad accounts.

How it works
Four steps. You know what happens when, and you can stop after any of them.
- 01
Audit of the current setup
Using preview mode and the network log, I work out which tags fire, which fail, and where the same purchase gets counted more than once. The result is a concrete list of what has to go and what is missing.
- 02
A new structure in GTM
The container is rebuilt with consistent naming and a clean data layer, so anyone can open it a year from now and understand what happens. Old tags are archived rather than deleted, so nothing is lost.
- 03
Server-side and consent mode
I set up a server container on your own subdomain and wire in consent mode, so the consent choice controls what gets sent. Conversion tracking for Google Ads and Meta moves over with it.
- 04
Checked against order data
For a period after launch, I compare orders in your backend with the numbers in GA4 and the ad platforms. Deviations are explained in writing, so you know how much weight the numbers can carry.
