Google Tag Manager vs Google Analytics 4: Which one should you go with?

When it comes to digital marketing and tracking website performance, businesses often find themselves debating Google Tag Manager vs Google Analytics.

When Google Tag Manager was introduced in 2012, it left many people puzzled. The concept of tag management was relatively unknown, and most didn’t understand how Google Tag Manager differed from Google Analytics, or even what it was meant to do.

Even today, beginners are often confused about between the two.

Now, both tools offer powerful insights, but they serve different purposes. Understanding how these tools differ can help you decide which is best suited for your business needs. So, let’s break it down to help you make an informed decision.

What is Google Analytics?

Google Analytics (GA), on the other hand, is a web analytics tool that tracks and reports website traffic. It gives you insights into user behavior, page performance, and marketing campaign effectiveness. Google Analytics helps businesses understand how users interact with their website, which can inform future marketing strategies and user experience improvements.

GA4 is the fourth major version of this tool and has been updated to better meet modern needs. It focuses more on user privacy and follows new data protection laws. GA4 also includes new features like smarter insights using machine learning, more flexible tracking of user actions, and better ways to track users across different devices.

In short, GA4 offers improved features and a focus on privacy to help you better understand and improve your digital marketing strategies.

Key Features of GA4

• Event-based Tracking: GA4 shifts from session-based tracking to an event-based model. This approach provides a clearer view of user engagement by focusing on actions users take. This data model has been widely adopted by other analytics tools in the industry for better accuracy and insight.
• Unified Web and App Data: GA4 collects data from both your website and app within a single property. This unified approach helps provide a more complete understanding of the entire user journey across platforms.
• Debugging: GA4’s DebugView feature makes it easier to troubleshoot and verify data. You can see live data coming in with all the details, offering more confidence in your tracking compared to Universal Analytics, where you had to rely on real-time reports or wait for data to appear in standard reports.
• Privacy Controls: GA4 enhances user privacy by default and continually improves these features. You can set data retention periods, select reporting identities, delete specific data subsets, and automatically anonymize IP addresses (a feature that cannot be turned off).
• Improved Integration: Google Ads now integrates more effectively with GA4, allowing you to create audiences based on events rather than just sessions. Additionally, GA4 can be linked to BigQuery, a feature previously available only to paid UA customers, enabling advanced data analysis outside of GA4’s interface.
• Cross-domain Tracking: Tracking users across multiple domains is simplified in GA4. You can manage this without needing to deal with code directly or access your GTM account—just add your domains to the tag settings of the data stream.
• Enhanced Measurement: GA4 includes automatic tracking for core user interactions, which was not as straightforward in Universal Analytics. These events can be enabled directly from GA4’s admin settings.
• Explorations: GA4 offers advanced reporting through Explorations. This feature allows you to build custom reports such as tables, funnels, and path analyses, providing greater flexibility and insight beyond standard reports.
• User-Centric Data Model: GA4 introduces a user-centric data model that tracks individual user journeys more effectively. This model provides a better understanding of user behavior over time, helping to create more personalized marketing strategies.
• Predictive Metrics: GA4 includes predictive metrics powered by machine learning. These metrics can forecast future user actions, such as the likelihood of conversion or churn, allowing you to make proactive adjustments to your marketing efforts.
• Custom Dimensions and Metrics: GA4 offers more flexibility in creating custom dimensions and metrics compared to Universal Analytics. This customization helps track specific user interactions or business goals more accurately.
• Data Stream Configuration: GA4 allows for detailed configuration of data streams, including settings for user properties and events. This customization enhances data collection and reporting based on your specific needs.

These features highlight GA4’s advancements over Universal Analytics and its capabilities to address modern digital marketing challenges. As GA4 continues to evolve, it will likely introduce even more enhancements to support the dynamic landscape of digital marketing.

What is Google Tag Manager?

Google Tag Manager (GTM) is a tool that simplifies the management of tracking codes on your website. Instead of manually adding and updating code for various tracking tools like Google Analytics 4 (GA4), GTM lets you manage everything from one central place.

How It Works

1. Centralized Management: GTM allows you to add and manage different tracking codes and tags, such as those for GA4, Google Ads, Meta, X (formerly Twitter), LinkedIn, and more, without needing to modify your website’s code directly.
2. Easy Implementation: By installing a single GTM code snippet on your website, you can then use GTM’s interface to set up and adjust your tracking tags. This makes it much easier to manage and update your tracking setup compared to manually coding each event.
3. Flexibility: GTM supports various types of tags, including analytics, ad tracking, remarketing, and custom code. This flexibility helps streamline your tracking efforts and ensures all your data collection is organized in one place.

Google Tag Manager vs Google Analytics: What’s the difference?

1. Purpose and Functionality

• Google Tag Manager is a tag management system that enables the implementation of tracking tags across a website without directly altering the site’s code. It acts as a container where you can insert multiple tags, including those for Google Analytics, Facebook Pixels, and more.
• Google Analytics is a dedicated analytics platform that tracks and reports on user behavior, traffic, and conversions on your website. It uses tags to collect data, but these tags are usually inserted via a tool like GTM or directly into the site’s code.

In short, GTM helps you manage the tags that collect data, while GA helps you analyze the data collected.

2. Ease of Use

• Google Tag Manager is user-friendly once you understand how it works. It simplifies the process of managing multiple tags without needing to edit your website’s code, which can be beneficial for non-developers.
• Google Analytics requires a basic level of understanding to configure reports and interpret the data, but it’s relatively easy to use once set up.

In the comparison of Google Tag Manager vs Google Analytics, GTM may have a steeper learning curve at first, but it’s invaluable for managing multiple tracking elements, while GA’s interface is more straightforward for analyzing data.

3. Customization and Flexibility

• Google Tag Manager allows for endless customization by enabling you to set custom triggers, variables, and events based on user interactions. You can set up complex tracking mechanisms without relying on developers every time.
• Google Analytics offers customization in the form of custom reports, goals, and event tracking. However, the tracking itself is often dependent on GTM or manually inserting the tracking code.

When it comes to Google Tag Manager vs Google Analytics in terms of flexibility, GTM offers more options for tailoring your tracking setup, while GA offers flexible data reporting.

4. Team Collaboration

• Google Tag Manager facilitates collaboration between marketing and development teams. Marketers can add and modify tags without having to rely on developers to make changes in the site’s code.
• Google Analytics is more focused on reporting data for decision-makers, with limited collaboration features when it comes to actual tracking setup.

5. Error Reduction

One of the biggest advantages of GTM is that it reduces the risk of manual errors in code placement. Tags can be implemented through the interface, and errors can be tested before deployment. Google Analytics, by comparison, offers fewer options for error testing when tracking codes are inserted directly into the website’s code.

Do You Need Both Google Tag Manager and Google Analytics?

The debate between Google Tag Manager vs Google Analytics is often misunderstood. These tools are not mutually exclusive. In fact, they work best when used together. Google Tag Manager helps you deploy and manage tags, including the Google Analytics tag.

When to Use Google Tag Manager?

You should use Google Tag Manager if:

• You need to manage multiple tags across different platforms.
• You want to track complex user interactions like button clicks, form submissions, or video views.
