Free Resource
A curated Notion doc of the resources we actually use to diagnose tracking problems: how systems work, how they fail, and how to fix them across every major marketing platform.
What's inside
The Masterdoc pulls together vetted guides, tools, and vendors across six areas. Not a link dump. Every resource is one Barbara and Timo have used or checked.
Tracking plans, event design, and how to refactor a setup that's grown messy.
GTM server-side setup, the vendors worth knowing, and what actually changes when you move server-side.
Meta Pixel and TikTok event setup, done properly.
GTM preview mode, GA4 discrepancies, postback failures, and our own troubleshooting process.
Catching tracking failures before they hit your reporting.
SKAdNetwork, iOS changes, and what they did to mobile attribution.
Most teams don't need all of it. But when something breaks, you'll know where to start.
It's free, and we keep it updated. Add your details and we'll send the link.
