Compared to Universal Analytics (UA), Google Analytics 4 (GA4) offers a more flexible, event-focused approach to tracking user behavior and greater granularity.
Events can be compared to individual user interactions, such as page views, specific clicks on a particular call to action or purchase form submissions. Configuring and analyzing these events against your market goals and KPIs measures performance, and gain granular insight into how people interact with your website.
This data can help identify audience segments and the channels that generate the most qualified users, or those who intend to purchase or complete specific actions on the site.
What are events in GA4?
In GA4, everything revolves around events. Unlike UA, which had different “hit types” (pageviews, transactions, etc.), GA4 simplifies things: Every interaction is tracked as an event.
There are three main event types to know:
- Automatically collected.
- Recommended.
- Custom events.
Automatically collected events
These include first_visit, session_start, page_view or file_download, which don’t require specific implementation or setup. All GA4 accounts have these by default, providing foundational insight into how users navigate and interact with your website.
Recommended events
These are specific events Google suggests tracking to help you understand user behavior and business performance. These can include events like:
- Logging in to a user account.
- Completing a purchase or refund.
- Performing a site search.
- Adding an item to a cart.
- Beginning the checkout process.
It is crucial to mark business-critical or essential KPIs as key events. Key events tell Google Analytics to treat the event as a conversion. GA4 will highlight them in reports and dashboards, providing more accurate fill-from-in segmentation and supporting attribution modeling.

Custom events
You can set up and add these events to define and track specific interactions that are important to your business but are not automatically covered or collected.
These can include tracking users when they:
- Donate.
- Interact with a specific call to action or buttons on a page.
- Accept a cookie consent banner.
- Interact with particular fields.
- Use specific filters or facets on ecommerce product pages.
Mapping events to KPIs
You must align your event and GA4 tracking strategy with your marketing and business key performance indicators to get the most out of GA4 features and data insights.
Events can provide a measurement framework, and KPIs can give them further context and direction. You can utilize the API from GA4 to create better reporting in Google Sheets or another platform, or even lightweight reporting in Looker Studio to keep an active viewpoint on how well your website contributes to your overall KPIs.
First, you need to understand what success looks like. Combining these can lead to long-term overall success, whether more sales, leads or high user retention.
As an ecommerce brand or SaaS company, your goal might be to increase purchases or generate more demo requests. While your main KPI may be quantitative, such as total revenue or demo requests, achieving these goals requires monitoring other user interactions.
You want to understand how users are engaging with your products.
- Are they adding items to their basket?
- Are users interacting with key pages like product or blog content if you’re a SaaS brand?
- Are your calls to action clear and being clicked?
These signals help move users from researching your product to signing up for a trial or getting in touch.
You can build a more substantial data narrative by mapping events that directly support or contribute to your primary KPI. As a result, it will be easier to show how your marketing efforts are working, even when there isn’t direct attribution to the final KPI.
Common KPI examples and the events to track them
GA4 is highly adaptable to different business needs, and there are many scenarios in which you may want to track more than just the basics.
You can track metrics like page views, scroll events and click patterns for user engagement. You can also look at metrics such as engaged sessions, session duration or a variation of bounce rate.
Creating a custom event for “quick backs” is applicable. When a user visits a page but quickly hits the back button to return to a previous page, this can signal a poor experience or mismatched content, even though the user didn’t leave the site.
It’s also valuable to track micro-conversions across your site. These include actions like add-to-cart events, newsletter sign-ups or video plays. While add-to-cart events are significant for understanding the ecommerce conversion funnel, tracking these behaviors can help you better understand your audience.
This deeper insight can improve how you build remarketing audiences or analyze pre-conversion behavior, ultimately supporting more intelligent marketing and content decisions.

Understanding event metrics in GA4
Once set up, events will trigger in Google Analytics, providing several valuable metrics to help you understand user behavior.
Event count per user
This metric shows how often a particular event occurs on average for each user. It helps you assess whether users repeatedly engage with key actions — for example, watching multiple videos during a visit; telling you how users interact with your content and where they might be in the funnel.
Event value
Event value is the sum of any value parameters sent along with an event. It’s beneficial when tracking things like revenue, lead value, average order value, or even custom goal scoring. It helps you assign weight or importance to specific user actions.
Important note on scopes
When working with event metrics in GA4, remember that dimensions and metrics must share the same scope — event, session or user level — for the data to be valid. That is a change from UA and something to watch out for when building custom reports or using Explorations.
Continuous analysis and refinement
When used correctly, Google Analytics 4 can be a key to understanding your audience, optimizing your website experiences and growing your business.
Tracking is never a “set it and forget it” process. You must continuously review your Google Analytics 4 data and regularly revisit your KPIs and events. You also need to look for any unexpected behavior, anomalies or longer-term shifts in user behavior.

### Understanding GA4 and the Event-Based Model
Unlike Universal Analytics (UA), which relied heavily on sessions and pageviews, GA4 is built on an event-driven data model. Every interaction—whether it’s a pageview, click, video play, or form submission—is tracked as an event. This model provides greater flexibility and customization, allowing businesses to define and measure the interactions that matter most to them.

### What Are Key Performance Indicators (KPIs)?
KPIs are measurable values that indicate how effectively a company is achieving its business objectives. In digital marketing and web analytics, KPIs might include:
– Conversion rate
– User engagement
– Average session duration
– Bounce rate (now replaced with engagement metrics in GA4)
– Revenue per user
– Form submissions
– Product views or adds to cart
By aligning GA4 events with your KPIs, you can gain deeper insights into user behavior and campaign performance.

### Setting Up Events in GA4
GA4 comes with several predefined events, but you can also create custom events tailored to your specific KPIs. Events in GA4 consist of:
– **Event name**: A string that identifies the event (e.g., `purchase`, `form_submit`, `video_play`)
– **Parameters**: Additional information about the event (e.g., `value`, `currency`, `page_location`)
**Types of events in GA4:**
1. **Automatically collected events** – Tracked by default (e.g., `first_visit`, `session_start`)
2. **Enhanced measurement events** – Enable tracking of common interactions like scrolls, outbound clicks, and site search
3. **Recommended events** – Suggested by Google for specific industries (e.g., `login`, `sign_up`, `purchase`)
4. **Custom events** – User-defined events tailored to specific business needs

### Mapping KPIs to GA4 Events
To effectively measure KPIs, you need to map each KPI to a corresponding GA4 event. Here are some examples:
| KPI | GA4 Event | Parameters |
|—–|———–|————|
| Conversion rate | `purchase` or `form_submit` | `value`, `currency`, `transaction_id` |
| User engagement | `user_engagement` | Automatically tracked |
| Average session duration | Calculated from `session_start` and `user_engagement` |
| Product interest | `view_item`, `add_to_cart` | `item_id`, `item_name`, `price` |
| Lead generation | `generate_lead` | `form_id`, `page_location` |

### Creating and Tracking Custom Events
To track custom KPIs, you may need to create custom events. This can be done in several ways:
1. **Using Google Tag Manager (GTM)**: Set up triggers and tags to fire custom events based on user interactions.
2. **Direct implementation via gtag.js or Firebase SDK**: Developers can push custom events directly into GA4.
3. **GA4 UI**: You can create new events based on existing ones using the “Create Event” feature in the GA4 interface.
**Example: Tracking a Newsletter Signup**
– Event name: `newsletter_signup`
– Parameters: `email_domain`, `signup_location`
Once created, this event can be used to measure the effectiveness of email marketing campaigns or landing pages.

### Using Conversions to Measure Success
In GA4, you can mark any event as a conversion. This is crucial for tracking KPIs related to business goals.
**How to mark an event as a conversion:**
1. Go to the GA4 Admin panel.
2. Click on “Conversions.”
3. Click “New conversion event.”
4. Enter the event name (e.g., `purchase`, `form_submit`, `newsletter_signup`).
Once marked, GA4 will track how often this event occurs and attribute it to traffic sources, user segments, and more.
