Quick Summary

Tags are code snippets you want to run (GA4 tag, Google Ads conversion tag, Meta Pixel). Triggers tell GTM when to fire a tag (page view, click, form submission, scroll, custom event). Variables provide dynamic data for tags and triggers (page URL, click text, form ID, Data Layer values). Every GTM implementation combines these three: a Tag (what), a Trigger (when), and optionally Variables (with what data). Understanding this framework is the key to mastering GTM.
