Google Tag Manager Essential Components

Google Tag Manager (GTM) consists of several essential components that work together to streamline the management of tags, triggers, and variables on your website or app.

Let’s explore these building blocks in more detail:

Trigger

A trigger is a condition that determines when a tag should fire. It provides instructions to Google Tag Manager regarding the timing (when), location (where), or conditions (how) for firing a tag.

Basically, triggers allow you to control when and how your tags collect data.

For example, you can set a trigger to fire a tag when a user clicks a button, views a page, submits a form, or performs any other action on your website or app.

You can also use triggers to fire tags based on variables, such as the URL, the device type, the referrer, or the cookie value.

Google Tag Manager provides several built-in triggers for common events, such as:

Page views,
Clicks,
Form submissions,
Scroll depth
Timer
Video plays, and more

You can also create custom triggers for more specific events, such as scrolling, hovering, video plays, etc.

Variable

In order for the tag and trigger to function properly in Google Tag Manager (GTM), a variable is required.

This variable provides the additional information that GTM needs to ensure the tag and trigger work as intended.

Essentially, a variable is a placeholder that can store and retrieve information. It makes your tags and triggers more flexible and adaptable to different contexts.

For example, you can use a variable to store the value of a form field, the name of a product, the category of a page, or any other data that you want to use in your tags or triggers.

Google Tag Manager provides several built-in variables for common data sources, such as:

Page URL,
Page title,
User ID
Click text,
Click URL,
Browser type,
Device type and more.

You can also create custom variables for more specific data sources, such as data layer variables, JavaScript variables, first-party cookies, and so on.

Other GTM Essential Components

In addition to tags, triggers, and variables, Google Tag Manager (GTM) includes other important components.

These components work together to make managing tags, triggers, and variables on your website or app easier.

They work seamlessly to simplify the entire Google Tag Manager process.

Container

The container is the core element of GTM. It acts as a virtual container that holds all your tags, triggers, and variables. When you start using GTM, you create a container specific to your website or app. You’ll receive a unique container ID that needs to be placed in your website’s code.

Data Layer

The Data Layer is an optional but powerful feature that enables you to pass structured data from your website or app to GTM. It serves as a JavaScript object that holds information about user interactions and page events. Utilizing the Data Layer allows you to create more specific and accurate triggers and variables.

Workspace

The workspace is the visual interface within GTM where you create, edit, and manage your tags, triggers, variables, and other GTM elements. It provides a user-friendly environment for organizing and controlling your tag management activities.

Preview and Debug

The Preview and Debug mode in GTM allows you to test your tags before publishing them to your live site. It provides real-time insights into which tags are firing and helps you identify and debug any issues. This mode is essential for ensuring that your tags are working as intended.

Version Control

GTM includes version control functionality, which tracks the changes you make to your container. This feature allows you to revert to previous versions if needed, providing a safety net and preventing accidental errors from impacting your live site.

User Permissions

GTM enables you to control user permissions, determining who has access to your GTM container and the actions they can perform. This ensures that only authorized users can make changes to your tags, maintaining security and control over your tag management process.

Understanding these various components of GTM will help you effectively manage and optimize the tracking and marketing activities on your website or app.

How does Google Tag Manager Work?

Google Tag Manager works by using a container that holds all your tags, triggers, and variables.

A container is a piece of code that you install on your website or app once and then use to manage all your tags from the Google Tag Manager interface.

The container code communicates with the Google Tag Manager servers and downloads the latest configuration of your tags, triggers, and variables.

Then, it executes the tags according to the triggers and variables that you have set up.

Google Tag Manager (GTM) acts as a central conductor for all the tracking snippets (tags) on your website.

Imagine it like a control panel where you manage different instruments in an orchestra.

Instead of music, you’re directing data collection. You install one small GTM code snippet across your site, then add individual tracking tools like Google Analytics and Facebook Pixel as “tags.”

GTM waits for specific user actions like page views or button clicks, which act as “triggers.”

When a trigger activates, GTM sends the relevant tag into action, injecting its code into the website.

This tag then collects data based on the user’s activity, like what they clicked or how long they scrolled, and relays it to the right tracking platform.

GTM simplifies managing all these tags without touching the website code.

It provides centralized control, faster updates, and better data accuracy, allowing you to understand your visitors and optimize your site’s performance.

Google Tag Manager Setup Guide

Setting up Google Tag Manager is similar to setting up your Google Analytics tracking code. The process involves adding two code snippets to every page on your website.

One snippet is inserted into the <head> section of your HTML code, and the other is placed in the <body> section.

Obtaining these code snippets is simple: log into your Google Tag Manager account and create an account container. Google provides a detailed quick-start guide to assist you throughout the setup process.

If you are using WordPress content management system (CMS) platform, check if your theme has a designated area in the admin settings where you can easily paste the two Tag Manager code snippets.

If your platform does not have built-in settings to insert the code correctly, you can explore plugins specifically designed for your platform. These plugins will assist you in seamlessly integrating Google Tag Manager into your website.

Although GTM is highly regarded for its benefits on custom-built websites, it is equally valuable when implemented on WordPress sites.

WordPress websites are renowned for their user-friendly nature, ease of customization, and simplicity, making them an ideal option for small businesses and startups.

Fortunately, there are several plugins available that enable even the least technically inclined website owners to effortlessly incorporate the GTM container code.

By leveraging these plugins, WordPress users can swiftly embark on their journey with Google Tag Manager, unlocking its productivity-enhancing capabilities.

If you are a WordPress site owner, you can easily install Google Tag Manager on your WordPress site.

Note:

After installation, it is important to ensure that the code is correctly inserted into the actual HTML. To do this, visit your site and check for the code after the <head> tag and after the <body> tag.

Keep in mind that some CMS platforms may not display the tracking code while you’re logged in as an administrator. To bypass this, open your site and view the HTML source code in a private browsing window.

Google Tag Manager and Google Analytics

Google Tag Manager is a tool that allows marketers to manage various tags.

Among these tags is the tracking code for Google Analytics 4, which marketers can add to their websites or apps to monitor traffic.

It’s essential to note that Google Tag Manager serves a distinct purpose—it is specifically designed for storing and managing third-party code.

However, it doesn’t provide reports or any means of analysis within GTM itself.

For reporting and analysis, marketers turn to Google Analytics. All conversion tracking goals and filters are handled through analytics.

Any reporting activities, such as conversion reports, custom segments, e-commerce sales, time on page, engagement reports, and more, are conducted in GA4.

In fact, marketers use Tag Manager to specify the information sent to Google Analytics, including track type, event tracking parameters, user actions, and more.
