About Tags
A GTM tag is a piece of JavaScript code that sends information to a third party, such as Google Analytics.
With Google Tag Manager, you no longer need to maintain each of these JavaScript snippets in your source code. Instead, you specify the tags that you want to fire, and when you want them to fire, from within the Google Tag Manager user interface.
Triggers and Trigger Types
A trigger is a condition that evaluates to either true or false at runtime. Triggers attached to a tag govern when the tag is fired or not fired.
A tag must have at least one trigger in order to fire. Triggers are evaluated during runtime and associated tags are fired (or not fired) when the trigger conditions are met. For example, a tag with a trigger based on a pageview event with the following filter will be fired on the example.com home page: url equals example.com index.html
