Google Tag Manager (GTM) lets you add tracking codes to your website without editing code each time.
What GTM Does
GTM acts as a container for all your tracking scripts. Google Analytics, Facebook Pixel, Google Ads, and more. You manage them from one dashboard.
Key Concepts

Triggers

Variables

Data Layer
A JavaScript object that passes structured data from your website to GTM.
