In the world of web analytics, Google Analytics has been a dominant force, empowering businesses to understand and optimize their online presence. With the evolution of technology and changing user behaviors, Google has introduced a new iteration called Google Analytics 4 (GA4) as a successor to Universal Analytics. GA4 brings forth a host of new features, improvements, and a shift in its underlying approach to tracking, reporting, and analysis. Understanding the difference between Google Analytics 4 and Universal Analytics is crucial for businesses aiming to harness the power of data-driven insights to drive growth and success.
In this GA4 vs. Universal Analytics article, we will put them against each other and see which one reigns supreme.
GA4 vs. Universal Analytics
In Universal Analytics, the data model is session-based, which means it primarily focuses on tracking user interactions within a specific session or visits to a website. It categorizes data into hits, sessions, and users.
A hit represents an interaction that is tracked, such as a pageview, event, or transaction. A session in Universal Analytics represents a period during which a user engages with a website. A user represents a unique individual who visits a website.
On the other hand, GA4 introduces an event-based data model, which is designed to track user interactions and events across multiple platforms and devices. It shifts the focus from sessions to individual events and emphasizes the importance of tracking specific actions taken by users.
In GA4, an event is a fundamental unit of measurement. It represents a specific user action, such as a button click, video view, or form submission. Events are categorized based on predefined parameters, including event name, event category, and event action. This allows for more granular tracking of user interactions.
GA4 also takes a user-centric approach, meaning it places greater emphasis on tracking individual users and their actions across different devices and platforms. It uses enhanced measurement capabilities to associate events with specific users, enabling a more holistic understanding of user behavior.
Reporting and Analysis
Next in GA4 vs. Universal Analytics is reporting and analysis. In Universal Analytics, the reporting and analysis capabilities are focused on providing a wide range of standard reports and customization options. Here's a further elaboration on the features available:
- Standard Reports: Universal Analytics offers a comprehensive set of prebuilt reports that cover different aspects of website performance and user behavior. These reports include Audience, Acquisition, Behavior, and Conversion reports. They provide insights into metrics like pageviews, sessions, users, traffic sources, conversion rates, and more.
- Customization Options: Universal Analytics provides flexibility for customization. You can create custom reports by selecting dimensions (attributes) and metrics (quantitative data) based on your specific needs. This customization allows you to analyze data in a way that is relevant to your business objectives and goals.
- Goals and Funnels: Universal Analytics allows you to set up goals and track conversions on your website. Goals can be defined based on specific user actions, such as completing a purchase, submitting a form, or spending a certain amount of time on a page. Funnels can be created to track the steps users take to complete a specific goal, helping you identify areas of drop-off or optimization opportunities in the conversion process.
- Segmentation: Universal Analytics offers segmentation capabilities to analyze specific subsets of users or sessions. Segments can be based on demographics, behavior, traffic source, or custom dimensions/metrics. By segmenting your data, you can gain deeper insights into different user groups, compare performance across segments, and uncover patterns or trends.
- Custom Dimensions/Metrics: Universal Analytics allows the creation of custom dimensions and metrics. Custom dimensions enable the capture of additional data about users or sessions beyond the default set of dimensions. Custom metrics, on the other hand, allow you to define and track custom numerical values related to your business goals.
On the other hand, GA4 introduces a new reporting interface and updated features that focus on a different approach to reporting and analysis:
- Analysis Hub: GA4 emphasizes the use of the Analysis Hub, which provides a more exploratory and ad-hoc analysis experience. It allows you to perform advanced analysis by asking questions about your data and getting instant insights. The Analysis Hub includes features like Exploration, Funnel Analysis, Path Analysis, and Segment Overlap, enabling you to delve deeper into your data.
- Event-Centric Reporting: GA4's reporting is centered around events, which are specific user actions tracked on your website or app. The reporting provides insights into event parameters, such as event name, event category, and event action. This focus on events enables you to understand user interactions and behaviors in a more detailed manner.
- User Properties and Audiences: GA4 emphasizes user properties, which are attributes associated with individual users. These properties can include demographic information, device characteristics, or custom user attributes. GA4 allows you to create audiences based on these user properties, enabling you to target specific user segments for analysis or marketing campaigns.
It is evident from this GA4 vs. Universal Analytics comparison that GA4 is better at reporting and analysis.
Data retention refers to the duration for which the data collected in an analytics platform is stored and available for analysis. Here's a further elaboration on data retention in our Google Analytics 4 vs. Universal Analytics guide.
In Universal Analytics, the data retention period is based on the user's chosen settings. Universal Analytics allows users to configure the data retention period, which can range from a minimum of 14 months to unlimited. This means that you can choose how long you want to retain the data collected in Universal Analytics before it is automatically deleted.
On the other hand, GA4 has a default data retention period of 14 months. This means that data collected in GA4 is stored for 14 months by default. However, GA4 also provides an option to extend the data retention period up to 26 months. This extended retention period allows you to retain your data longer if needed.
Data retention settings in both Universal Analytics and GA4 apply to the raw data collected by the analytics platform. Aggregated and processed data, such as reports and analysis, may still be available even after the data retention period has passed. The data retention period primarily affects the availability of raw data for deeper analysis or reprocessing. This means that in our Google Analytics 4 vs. Universal Analytics comparison, both are equally good on the data retention front.
Up next in the Universal Analytics vs. GA4, comparison is the tracking methods used by them.
Key points about tracking in Universal Analytics:
On the other hand, GA4 introduces more flexible tracking options and enhanced capabilities:
- Enhanced Tracking for Mobile Apps: GA4 offers improved tracking capabilities specifically designed for mobile apps. It provides SDKs (Software Development Kits) for different mobile platforms (iOS and Android), which allow developers to integrate GA4 tracking directly into their mobile apps. This enables comprehensive tracking of user interactions and events within mobile applications.
From this Universal Analytics vs. GA4 comparison, we can easily say that GA4 is better at tracking.
Cross-device tracking refers to the ability to connect user interactions and activities across multiple devices, such as smartphones, tablets, and computers, to gain a comprehensive understanding of the user journey. Here's a further elaboration on cross-device tracking in UA vs. GA4:
In Universal Analytics, cross-device tracking requires the implementation of additional techniques to connect user interactions across multiple devices:
- User ID: Universal Analytics provides the User ID feature, which allows you to assign a unique identifier to users. By implementing User ID tracking, you can associate user interactions and activities across different devices and sessions. However, User ID tracking requires users to be logged in or provide identifiable information consistently across devices for accurate tracking.
- Cross-Domain Tracking: Universal Analytics offers cross-domain tracking capabilities, which enable the tracking of user interactions across multiple websites or domains. This allows you to connect user sessions and behavior as users navigate different websites under the same tracking property.
On the flip side, GA4 introduces built-in cross-device tracking capabilities to provide a more holistic view of the user journey without requiring additional techniques:
- Enhanced Measurement Model: GA4 utilizes an enhanced measurement model that automatically stitches together user interactions and events across different devices and platforms. This means that when a user interacts with your website or app on multiple devices, GA4 can associate those interactions and provide a unified view of the user's journey.
- Persistent User IDs: GA4 assigns persistent user IDs to individual users, allowing them to be recognized and tracked across multiple devices and sessions. This tracking is done using a combination of unique identifiers, such as device IDs and login information, to connect the user's interactions and activities.
GA4 again takes the lead in the UA vs. GA4 comparison.
