Google Tag Manager (GTM)
A tag management system that lets you deploy and manage tracking scripts on your website without editing code.
Why It Matters
GTM eliminates developer dependency for tracking changes, letting marketers add, edit, or remove tags in minutes instead of weeks.
How It Works
You install a single GTM container script on your site. Inside GTM, you create tags (tracking scripts), triggers (when to fire), and variables (dynamic values). Changes are published instantly without a code deploy.
Real-World Example
A marketer adds a Meta Pixel event for "Add to Cart" clicks in GTM using a click trigger, without asking engineering for a code release.
Common Mistakes
Publishing GTM changes without using Preview mode first
Creating duplicate tags that double-count conversions
