Understanding Google Tag Manager
Google Analytics 4 (GA4) is the latest version of Google Analytics, designed to collect event-based data on conversions and valuable actions happening on your website. It tracks user interactions across web pages, providing valuable insights into how visitors engage with your website and mobile app.
GA4, Google tags, and Google Tag Manager (GTM)
To maximize the benefits of GA4 for your website, it’s essential to use Google Tag Manager (GTM). GTM acts as a bridge, allowing your website to communicate with GA4, ensuring that GA4 accurately collects data on user interactions and activities on your site.
For most websites, setting up GA4 isn’t as simple as creating an account and automatically connecting it to your site. However, some website platforms like Shopify, Squarespace, and Wix make integration easy—allowing you to add your GA4 ID in the settings to track key actions like visits and eCommerce purchases.
That said, it’s still crucial to track non-standard or unique interactions on your website using GA4. To do this, you need to follow specific steps to ensure the right data is being tracked. Understanding how GA4, Google Tag Manager (GTM), and Google tags work together will help you gain deeper insights into user behavior.
Key Components:
-
Google Tag: A snippet of code added to your website that allows data to be sent to GA4 and other Google products. This is what enables tracking of user activity.
-
Google Tag Manager (GTM): A tool that helps you manage all the tracking tags on your site in one place, ensuring you capture the data you need without manually editing website code.
-
Google Analytics 4 (GA4): The latest version of Google Analytics, designed to track events (user actions) and provide valuable insights into website traffic and engagement.
In the past, tags were manually embedded into a website’s HTML. Now, GTM simplifies this process by acting as an intermediary between your website and the tags you use. Instead of editing your site’s code, you can input all your tags into GTM, which then remotely deploys them on your website.
This gives you full control over your tracking setup—eliminating the need to rely on a developer every time you want to add or modify a tag. With GTM, you decide which tools and data sources are linked to your website.
Why do digital marketers use GTM?
Key Benefits of Google Tag Manager (GTM) for Digital Marketers

Centralized Tag Management – GTM serves as a single hub for managing all marketing tags. Instead of embedding multiple tracking codes directly into your website, you can organize and control them all within GTM.

Flexibility & Speed – Deploy and modify tags without altering website code, reducing reliance on developers. This allows for faster campaign rollouts, quick adjustments to tracking needs, and seamless A/B testing.
-
Enhanced Data Accuracy & Consistency – Managing tags in one place ensures consistent data collection while minimizing redundant or conflicting tags. Plus, GTM’s preview mode lets you test configurations before publishing.
-
Advanced Event Tracking & Customization – Easily set up tracking for specific user interactions. Combined with GA4’s event-based model, GTM enables in-depth insights that align with your business goals.
-
Improved Security & Version Control – GTM’s built-in version history allows you to track and revert changes when needed. Additionally,permission controls ensure that only authorized users can publish updates, enhancing security.
Elements of GTM
The three core components of Google Tag Manager are Tags, Variables, and Triggers.
Tag
A tag represents the specific event you want to track, such as a button click or link click. For example, you could create a tag named “buy_now_click” to track when users click the “Buy Now” button on your website.
Variable
Variables provide additional details about user actions on your website. They can include information such as the page where a button was clicked, the product associated with that button, or the date of the interaction. Without variables, you would only know that a “Buy Now” button was clicked, but not the context behind it.
Google Tag Manager collects these variables from your site, enabling you to configure tags that trigger based on specific combinations of actions and variables. This enhances reporting and allows for more precise tracking of user interactions.
Trigger
A trigger is the action or event that activates a tag and sends data to GA4. For example, when a user clicks the “Buy Now” button, the “buy_now_click” tag is fired. Variables then provide additional details, such as the time of the click or the product purchased.
Triggers monitor specific user actions on your website. You might have a trigger called “link clicks”, which activates when someone clicks a link with “Shop Now” as the text. When this action occurs, the trigger fires the tag, sending the relevant data to GA4.
Essentially, a trigger watches for user behavior that matches predefined tags and variables. When that action takes place, it ensures the data is captured and reported accurately.
Google Tag Manager (GTM) simplifies the process of tracking user interactions and managing marketing tags. It allows marketers to track events like button clicks, form submissions, and page scrolls—without needing a developer’s help. Without GTM, implementing such tracking would require direct coding and developer assistance.
