All About GA 4 Events

Getting your Trinity Audio player ready...

In Old version of Google Analytics Goal is present, But in New GA-4 We can see Event in Place of Goal.

An event in the context of website or app analytics refers to a specific interaction or occurrence that you can measure and track. Google Analytics, a popular web analytics tool, automatically collects certain events by default. However, you also have the ability to set up custom events on your website or app to collect additional data that is specific to your business goals and user interactions.

2. Enhanced event measurement

Enhanced measurement in Google Analytics allows you to track user interactions with your content by enabling specific options (events) directly within the Google Analytics interface. This feature eliminates the need for manual code changes on your website or app. Once you enable these options for a web data stream, your Google Analytics tag will immediately start sending events, capturing valuable user engagement data.

3. Recommended events

Predefined events are events that you can implement on your website or app, which come with predefined names and parameters. These events allow you to leverage existing and future reporting capabilities in your analytics tool.

4. Custom Events 

Custom events refer to events that you define based on your specific needs and requirements. They are created when no other predefined events adequately capture the interactions or occurrences you want to track. Unlike predefined events, custom events do not appear in most standard reports by default.

We can set Custom Event with help of below methods.

Methods to Set up a custom event

Set up your custom event using one of the following options:

• The Google tag (website)
• Google Tag Manager (website)
• Firebase (apps)
