Don’t trust your gut when doing anything in Google Analytics (or any other platform). Always check that the data is captured by the platform and that it appears in the report as you expect.
Fortunately, GA4 has a feature called DebugView.

Google Analytics 4 (GA4) has changed tracking and analysis of website’s data, presenting a more user-centric approach than Universal Analytics. One of its most remarkable characteristics is GA4 Debug View – an indispensable instrument for validating and troubleshooting your tracking setup in real time.In this guide, we will teach you how you can use GA4 Debug View effectively.

Overview of GA4 Debug View

Importance of Debug View in Analytics

Using Debug View in GA4 is essential for keeping your analytics accurate. It allows you to monitor events and user interactions in real time, so you can quickly identify and resolve tracking issues. Whether you’re a marketer, analyst, or developer, knowing how to use this tool can make a big difference in the quality of your data and the decisions you make based on it.

What is GA4 Debug View?

Definition and Key Features
GA4 Debug View is a feature within Google Analytics 4 that enables you to see events and user properties in real-time. This tool provides a detailed stream of events, making it easier to verify if your tracking setup is working as expected.

Differences from Universal Analytics
Unlike Universal Analytics, GA4 focuses on events rather than sessions, offering a more granular view of user interactions. The Debug View in GA4 provides a more detailed and real-time approach to tracking, which is a significant improvement over the traditional debugging methods in Universal Analytics.

Enabling Debug View in GA4

Using the Google Analytics Debugger Chrome Extension

1.Install the Extension: Add the Google Analytics Debugger extension to your Chrome browser.

2.Activate Debug Mode: Click on the extension icon to enable debug mode. This allows your GA4 property to start receiving debug data from your browser.

Setting up with Google Tag Manager Preview Mode

1.Enable Preview Mode: In Google Tag Manager (GTM), click on ‘Preview’ to enter preview mode.

2.Debug GA4 Events: With preview mode enabled, navigate your site to trigger events. GTM will send these events to GA4 in debug mode, making them visible in Debug View.

Enabling via the GA4 debug_mode Parameter

1.Add debug_mode Parameter: Include debug_mode: true in your GA4 configuration tag or in your event data.
2.Verify Debug Data: Check the Debug View in your GA4 property to ensure events are being recorded.

Navigating the Debug View Interface

1.Debug Device Selector
2.Minutes Stream
3.Seconds Stream
4.Top Events
5.User Properties


Debug Device Selector

You can choose the specific device’s data you wish to debug with the Device Selector. The DebugView’s top left corner is where you’ll find the selector.You may see numerous devices there if multiple visitors have activated the debug view (for example, by all having enabled the Chrome extension), and it may take some time to locate oneself.

Minutes Stream :

It displays a sequence of circles, one for each of the last 30 minutes (located on the DebugView’s left side). The circle’s number represents the total number of events that were received during that minute. When you click on one of these circles, events that were logged during that minute are displayed in the Seconds stream. This gives you a more thorough look at the events that have been logged throughout the last 30 minutes.


Seconds Stream

This is where most of the action/debugging takes place (middle column). A more detailed list of events can be found here. Every event has a timestamp shown on it that matches the moment it was logged on the development device. To view a list of an event’s parameters, click on it.

The DebugView interface’s other sections are interconnected with the Seconds stream. For example, the Seconds stream will scroll down (or up) to the specific occurrences of that minute if you click a circle (with a number) in the Minutes stream.

Top Events
The top logged events within a 30-minute period are displayed in the Top Events widget.
1.Any of the events can be clicked to work as a quick filter.
2.After you’ve done that, you can select a particular parameter and the timestamps of each parameter that was delivered along with that specific event for the last 30 minutes will be displayed.
3.Additionally, by selecting a certain timestamp, you can view all of the event’s parameters.
4.Seeing how (and when) the parameter values are altered as a result of that event is quite helpful.

User Properties
User properties displays the most recent version of the user property set for the device that is presently selected. To view the values’ changes over the last 30 minutes, click the small clock symbol.
