The GTM Container Template We Clone for Every Client
The tag list
GA4 config, GA4 events, Meta pixel, Meta CAPI, Google Ads conversions, LinkedIn Insight. That's the baseline for most accounts.
The variables
UTM parameters, page type, page path grouping, user role (if authed). These feed everything else. Set them up once.
Trigger discipline
Every tag has a documented trigger condition. No 'fires on all pages' unless truly necessary. Debug time drops 90%.
