Ever wondered how some marketers seem to track everything on their website with pinpoint accuracy? The secret lies in mastering Google Tag Manager's triggers and variables. Don't worry - you won't need to become a developer to understand this. Let's break it down into plain English.
What Are Triggers and Variables (And Why Should You Care?)
Think of Google Tag Manager (GTM) as a smart assistant for your website. Triggers are the "when" instructions you give to your assistant, and variables are the "what" information you want them to collect.
Real-World Example
Imagine you're running a physical shop:
Trigger = When a customer picks up a product
Variable = Which product they picked up, its price, and its category
Now, let's translate this to your website!
Understanding Triggers: Your Marketing Detective
Triggers are like trip wires that tell GTM when to spring into action. They're the difference between tracking everything (and drowning in data) and tracking the right things at the right time.
