Most financial brands think their tracking works until they try to tie ad spend to a funded account and the numbers do not add up. This checklist walks the full stack: GA4 configuration, Google Tag Manager, Enhanced Conversions, server-side tagging, and the deposit or KYC events that actually map to revenue.
Work through each item and you will find the gaps that quietly waste budget, conversions firing on the wrong page, deposits that never reach your ad platforms, duplicate events inflating your numbers. Fix those and every other decision you make on the data gets more reliable.
