Specialist GA4 GTM

Migrating to GA4 - Setting Up GTM

Analytics Tagging expert - GA4 event with server-side tagmanager and FB event

“Stijn was easy to work and conveyed trust. He responded to my messages within 24 hours. My project was small (update GA4 on website) and the due date was flexible so he squeezed me in. I had some concerns a couple of months later, so he checked everything for me again. I am happy with the work that was done and would absolutely recommend Stijn as a freelancer who can help with GA4.” less
