What is Google Analytics 4?

Google Analytics 4 (GA4) is Google’s new web and app analytics tool, designed to give businesses more granular and accurate insights into their customer journeys. Unlike the older Universal Analytics, GA4 focuses on event-based data collection, making it more adaptable to the growing complexity of user behavior, especially across multiple devices and platforms.

GA4 has been designed with an emphasis on privacy, improved tracking across devices, and the use of machine learning to automatically provide valuable insights. If you’re wondering “what is Google Analytics?” or “what are Google Analytics features?”, GA4 is the answer to all these questions as it represents a shift in how data is collected and processed.

How Does Google Analytics Work?

At its core, Google Analytics is a platform that helps you track and analyze your website traffic. It collects user data via cookies and tracks key actions that users take on your website or app. These actions are known as “events” in GA4, which can be anything from a page view to a click on a specific button. The data collected is then used to generate detailed reports that help businesses optimize their online presence.

If you’re wondering “how does Google Analytics work?“, it breaks down to the following key steps:

• Data Collection: Google Analytics for websites uses a unique tracking code placed on your website to collect data about user behavior.
• Processing the Data: Google processes the data and converts it into meaningful reports.
• Reporting: These reports help businesses understand user interactions, traffic sources, demographics, and much more.

Key Features of GA4

Google Analytics 4 introduces several game-changing features that provide a more flexible, privacy-centric, and powerful analytics platform. Understanding these features is key to harnessing GA4’s full potential. Let’s break down each feature in detail:

Event-Based Tracking Model

GA4 fundamentally changes how data is tracked and structured. While Universal Analytics relied on session-based tracking (which grouped interactions within a time-based visit), GA4 takes an event-driven approach. In GA4, every user interaction is treated as an event, giving more granularity to what users do on your platform. For example:

• Page Views are an event.
• Button Clicks, video plays, and even specific user interactions like form submissions are also events.

This allows for a much more detailed understanding of user behavior. Instead of focusing on sessions, GA4 allows you to track a wide variety of user actions and define the key interactions (events) that are critical for your business goals. This also means better tracking of complex, non-linear user journeys, especially across multiple devices.

Cross-Platform Tracking

One of GA4’s standout features is its ability to unify data from different platforms—such as websites and mobile apps—into a single property. In the past, Universal Analytics required separate properties for apps and websites, often leading to fragmented data. GA4 removes this barrier:

• Cross-device tracking: GA4 can track users across multiple devices (e.g., desktop, tablet, mobile).
• App + Web properties: You can merge app and web data into one view, giving you a full understanding of user behavior across platforms. This is crucial in today’s multi-device world, where users might browse on a phone but convert on a desktop or vice versa.

Enhanced User-Centric Data

With GA4, the focus is no longer on sessions but on users. This means Google website analytics provides a more user-centric view of data by focusing on individual users rather than just their sessions. This shift helps marketers and businesses better understand how users interact with their brand across multiple touchpoints.

GA4 allows you to create more detailed user journeys by tracking things like:

• User lifetime value (LTV): Measure how valuable a user is over time rather than just focusing on short-term metrics.
• Cohort analysis: Track how groups of users (based on shared characteristics like acquisition date) behave over time.

AI-Powered Insights and Predictive Metrics

Google has integrated its powerful machine learning algorithms into GA4, providing predictive metrics that weren’t previously available in Universal Analytics. These insights can help businesses make data-driven decisions by predicting future user behaviors:

• Churn Probability: GA4 can predict the likelihood that a user will stop engaging with your app or website. This is extremely useful for retention strategies.
• Revenue Forecasting: By analyzing historical user behavior, GA4 can forecast future purchases, helping businesses allocate marketing budgets more effectively.
• Suggested Trends: GA4 automatically highlights emerging trends or anomalies in user behavior, saving time by surfacing actionable insights without needing deep manual analysis.

Privacy-Centric Data Collection

With increasing global concerns over data privacy (e.g., GDPR, CCPA), GA4 has been designed to prioritize privacy and adapt to the changing regulatory landscape. GA4 offers more flexible data retention controls and anonymization features, such as:

• No reliance on cookies: GA4 can provide insights even without cookies, as it focuses on aggregate data rather than personal identifiers.
• User consent modes: If a user opts out of tracking (such as refusing cookie consent), GA4 is still able to deliver some insights by modeling user behavior instead of relying solely on personal data.

New Reporting Interface

GA4’s reporting interface is a major shift from Universal Analytics. The new layout is designed for flexibility, allowing users to create custom reports suited to their specific needs. While Universal Analytics had rigid pre-built reports, GA4 offers a more customizable approach through the Analysis Hub, where you can:

• Build bespoke reports from scratch.
• Use templates for common analysis types, such as funnel analysis, pathing, and segment overlap.
• Apply more granular filters to drill into specific user actions or behaviors.
• These changes make GA4 a much more powerful tool for businesses that need flexibility in their reporting.

Setting Up Google Analytics 4 (GA4)

Getting started with GA4 is straightforward, but it requires careful attention to ensure everything is tracked correctly.

Creating a GA4 Property

To begin, you need to create a GA4 property. Here’s a step-by-step guide:

• Log into your Google Web Analytics account.
• Click “Admin” in the lower-left corner.
• Under the “Property” column, select “Create Property.”
• Choose “Google Analytics 4” and follow the setup wizard to configure your new property.

Integrating GA4 with Your Website

You can add GA4 to your website in two ways:

• Google Tag Manager (GTM): This is the recommended method as it allows easy management of all tracking codes in one place. In GTM, create a new GA4 configuration tag and set it to fire on all pages.
• Direct Installation: You can also add GA4 directly by inserting the tracking code provided in your GA4 setup into your website’s header.

Setting Up Event Tracking

GA4 automatically tracks several key events like page views and scrolls. However, for more specific actions (e.g., form submissions or video plays), you’ll need to set up custom events:

• Go to the Events section in GA4.
• Click “Create Event” and define the conditions for your custom event (e.g., clicks on a specific button).

Connecting GA4 to Google Ads

To get the most out of GA4, integrate it with Google Ads. This allows you to track ad performance and conversions:

• In GA4, go to Admin → Product Links → Google Ads Linking.
• Select your Google Ads account and follow the prompts to complete the connection.

Migrating from Universal Analytics

If you’re already using Universal Analytics, you’ll want to start migrating to GA4. Google recommends running both versions simultaneously until you’re fully comfortable with GA4. Keep in mind that data from Universal Analytics won’t automatically carry over to GA4, so plan your migration carefully.

Navigating the GA4 Interface

Navigating GA4 may seem overwhelming at first, especially if you’re accustomed to Universal Analytics. However, once you get familiar with the layout, GA4’s interface becomes intuitive, offering more customization and flexibility. Here’s a deeper dive into some of its core components:

Home Screen Overview

The GA4 home screen is the first thing you see after logging in. It provides a summary of key metrics, offering an at-a-glance view of performance. Key elements include:

• Active users: Shows how many users are currently on your website or app.
• Revenue and conversions: Displays real-time insights into revenue and conversion metrics.
• Top events: Highlights the most frequent events that have occurred, such as page views or specific actions (e.g., purchases or form submissions).

This dashboard can be customized to show the most important metrics for your business, which is particularly useful for marketers who need quick, actionable insights without diving into detailed reports.

Realtime Reports

Realtime reports offer a live view of user activity as it happens. This is especially valuable during time-sensitive events like product launches or marketing campaigns. Realtime data includes:

• Active users: The number of users currently browsing your site or app.
• Traffic sources: Where users are coming from (e.g., organic search, social media, paid ads). Organic Traffic is something that is highly appreciated and hard to achieve at the same time, but also organic support is difficult to remove and paves a way for long term success.
• User behavior: What pages users are visiting, what events are being triggered, and how they’re engaging with your content.

For example, if you’re running a flash sale, realtime reports can help you monitor user activity in real time, allowing you to quickly adjust your strategies based on current behavior.

Lifecycle Reports

GA4’s Lifecycle Reports provide insights across different stages of the user journey, broken down into four key categories:

• Acquisition: Shows how users are finding your site (organic search, paid search, social media, etc.).
• Engagement: Tracks how users are interacting with your content. This includes metrics like page views, average session duration, and specific event triggers.
• Monetization: Focuses on revenue and eCommerce transactions. This is where you can track purchases, revenue per user, and other important eCommerce metrics.
• Retention: Highlights how often users return to your site or app, giving you insights into user loyalty and long-term engagement.

Events and Conversions

In GA4, events are the core building blocks of all user interactions. These events track everything from basic page views to more complex actions, such as completing a form or making a purchase. GA4 comes with several predefined events, but you can also create custom events to track more specific interactions.

Conversions are simply events that are deemed critical to your business goals, such as making a purchase, signing up for a newsletter, or submitting a form. In GA4, any event can be flagged as a conversion, and this flexibility allows you to tailor tracking to your specific objectives.

Exploration Hub

The Exploration Hub is where GA4 truly shines. It allows you to create highly customizable reports and visualizations that go beyond the standard reports available in Universal Analytics. Some key features include:

• Funnel Analysis: Track users through a predefined series of steps to see where they drop off (e.g., add-to-cart, checkout, payment).
• Path Analysis: See how users navigate through your site or app, showing you common paths they take and where they may get stuck.
• Segment Overlap: Compare different user segments to see how they interact with your site differently.

The Exploration Hub is incredibly powerful for marketers and analysts looking to gain deep insights into specific behaviors or trends.

Understanding and Using Reports in GA4

GA4’s reports are more customizable and flexible than those in Universal Analytics, allowing you to extract the exact insights you need.

Standard Reports

GA4 provides several pre-built reports, such as:
