TL;DR
Server-side GTM moves tag execution from the user's browser to a server you control. Instead of the browser sending data to Google, Meta, and TikTok directly, it sends data to your server-side GTM container, which processes and forwards it to each platform. Benefits: improved page speed (fewer client-side scripts), better data control (you choose what data is sent where), resilience against ad blockers and browser restrictions, and compliance with privacy regulations. Drawbacks: requires a cloud server (Google Cloud Run), adds hosting costs, and is more complex to set up and maintain.

Frequently asked
Questions & answers
How long does setup take?
Most configurations take 10-30 minutes. Full campaign setup and ongoing optimisation is a continuous process.
What budget should I start with?
Start with enough to generate at least 50 conversions per week for the platform's algorithm to learn effectively. This varies by industry and CPA.
When should I expect results?
Allow 2-4 weeks for the initial learning phase. Meaningful performance trends typically emerge after 30 days of consistent spending.
