Animated overview of the full workflow
TL;DR
Click Preview in GTM's top navigation, enter your website URL, and your site opens with a debug panel. The panel shows: Summary (which tags fired on each event), Tags (fired vs not fired with details), Data Layer (contents at each point), Variables (values at each event), and Errors. Test your complete user journey: load pages, click buttons, submit forms, complete purchases. Verify every tag fires when expected and does not fire when it should not. Only publish after thorough preview testing.
