What Is Google Tag Manager?

Google Tag Manager makes it easy to track websites since it provides a single location where marketers can manage all the marketing and analytics tags. Rather than having to add each tracking code to a website individually, marketers can fulfill many tracking needs using GTM. 

For example, if one wants to track clicks on a “Contact Us” button, GTM will recognize the click via a trigger and execute the right tag. The collected data will be transmitted to an analytics or advertising system. 

In simple terms:

GTM manages the tracking → Tags perform the action → Triggers decide when it happens → Variables provide additional information.

According to Google, some key terms in Tag Manager include tags, triggers, variables, and the data layer. (Google Tag Manager Help)

How Does Google Tag Manager Work?

A simple GTM workflow looks like this:

User Action → Trigger → Tag → Tracking Platform

For example:

1. A visitor clicks the “Get a Quote” button.
2. The GTM trigger detects the click.
3. The relevant tag fires.
4. The tracking information is sent to the selected platform.

This approach allows marketers to create and manage different tracking requirements from one place.

What Are Tags, Triggers, and Variables in GTM?

What Is a Tag in Google Tag Manager?

A tag is a tracking setup or code snippet that executes an action upon firing. Examples of tags are Google Tags, Google Analytics Event Tracking, Google Ads Conversion Tracking, Conversion Linker, and Custom HTML Tags. 

What Is a Trigger in Google Tag Manager?

A trigger decides when a tag fires. It can be an event-based trigger such as a page view, click, form submission, scroll, etc. 

For example:

Trigger: User clicks the “Contact Us” button
Tag: Send the interaction to the relevant tracking platform

What Are Variables in Google Tag Manager?

A variable is a value that can change in different conditions. Variables can be used in tags and triggers in GTM. 

Common variables include:

• Page URL
• Page Path
• Page Title
• Click Text
• Click URL
• Click ID
• Event

Variables can make tracking more accurate because they add more information to the interaction.

Understanding the Data Layer in GTM

The Data Layer stores website information that Google Tag Manager can use when setting up and processing tracking.  It includes information like events, product details, transaction value, page type, or any other information needed for tracking.

For basic implementations, the need for a custom data layer does not always arise. But for large-scale sites and e-commerce sites, a good data layer is advantageous because it offers a standard method of delivering information to GTM.
