What are tags?
Tags are snippets of code or tracking pixels from third-party tools. These tags tell Google Tag Manager what to do.Examples of common tags within Google Tag Manager are:
- Google Analytics Universal tracking code
- Adwords Remarketing code
- Adwords Conversion Tracking code
- Heatmap tracking code (Hotjar, CrazyEgg, etc…)
- Facebook pixels
What are triggers?
Triggers are a way to fire the tag that you set up. They tell Tag Manager when to do what you want it to do. Want to fire tags on a page view, link click or is it custom?
What are variables?
Variables are additional information that GTM may need for your tag and trigger to work. Here are some examples of different variables.
The most basic type of constant variable that you can create in GTM is the Google Analytics UA number (the tracking ID number).
Those are the very basic elements of GTM that you will need to know to start managing tags on your own.
