Understanding GA4 Events: The New Foundation
GA4 has completely overhauled how we track user interactions. Unlike Universal Analytics, which had a complex hierarchy of hits, sessions, users, and pageviews with separate tracking for events, GA4 simplifies everything into a single concept: events.
In GA4, everything is an event. Whether it’s a page view, button click, form submission, or e-commerce transaction, GA4 treats all interactions as events. This shift to an event-based model mirrors how modern websites and apps actually work today, where user journeys span multiple devices and interaction points.
| Universal Analytics Model | Google Analytics 4 Model |
|---|---|
|
This event-based approach offers several advantages:
- Simplified data model that’s easier to understand conceptually
- Consistent tracking across websites and mobile apps
- More flexible analysis capabilities without predefined report limitations
- Better alignment with modern privacy regulations
For marketing professionals, this means adapting to a new way of thinking about analytics, but it also opens up opportunities for more comprehensive tracking of marketing campaigns and user journeys.
Not sure if your GA4 implementation is tracking the right events? Let’s review your setup together.
Types of GA4 Events: Automatic, Enhanced, and Recommended
GA4 categorizes events into four main types, each serving different purposes and requiring different levels of implementation effort.
| Event Type | Description | Implementation | Examples |
|---|---|---|---|
| Automatically Collected Events | Basic events collected without any additional code | No setup required | page_view, session_start, first_visit |
| Enhanced Measurement Events | Additional events enabled through the GA4 interface | Toggle in GA4 settings | scroll, click, file_download, video_play |
| Recommended Events | Predefined events with specific parameters for common use cases | Manual implementation with specific naming | login, sign_up, purchase, add_to_cart |
| Custom Events | Events you define for specific business needs | Manual implementation and configuration | newsletter_subscription, product_review, custom_click |
Automatically Collected Events
These events are collected as soon as you implement the GA4 base code. They include fundamental interactions like:
- first_visit: When a user visits your site for the first time
- session_start: When a user starts a new session
- page_view: When a user views a page
- user_engagement: When a user has engaged with your page for at least 10 seconds
Enhanced Measurement Events
Enhanced measurement allows you to track additional common interactions without writing custom code. You can enable these in the GA4 interface under Data Streams → Enhanced Measurement:
- scroll: When a user scrolls to the bottom 90% of a page
- outbound clicks: When a user clicks a link to an external website
- site search: When a user performs a search on your site
- video engagement: When a user interacts with videos (plays, pauses, etc.)
- file downloads: When a user downloads a file
Recommended Events
Google provides a standardized set of events with predefined names and parameters for common business scenarios. Using these standardized events helps ensure compatibility with GA4’s features and reports.
Some key recommended events include:
- E-commerce events: view_item, add_to_cart, begin_checkout, purchase
- Retail/e-commerce events: add_payment_info, add_shipping_info
- Travel events: view_search_results, add_to_wishlist
- Gaming events: level_up, post_score, tutorial_begin
By following these standardized naming conventions, your data will automatically populate the right reports in GA4, making analysis much simpler.

GA4 Event Configuration: Setup and Implementation
Implementing GA4 event tracking requires a systematic approach, starting with the base measurement code and building toward more complex custom events. Let’s walk through the process:
Step 1: Install the GA4 Base Code
Before tracking any events, you need to install the GA4 base tracking code on your website. While Google Tag Manager (GTM) is the recommended approach for most businesses, you can also implement the code directly.
| Implementation Method | Pros | Cons | Best For |
|---|---|---|---|
| Google Tag Manager |
|
| Most businesses, especially those with frequent tracking changes |
| Direct Code Implementation |
|
| Simple websites with minimal tracking needs |
| CMS Plugins (WordPress, Shopify, etc.) |
|
| Small businesses with standard tracking requirements |
Step 2: Enable Enhanced Measurement
Once your base code is installed, navigate to your GA4 property, then:
- Go to Admin → Data Streams → Select your web stream
- Find the Enhanced Measurement section and toggle it on
- Click the gear icon to customize which events you want to track
Step 3: Implement Recommended Events
For recommended events, you’ll need to add code that sends these events with the exact names and parameters Google specifies. Here’s an example of implementing a purchase event using Google Tag Manager:
Example: Tracking a purchase event in GTM
- Create a new tag in GTM with the GA4 Event type
- Set the event name to “purchase”
- Add parameters like currency, value, transaction_id, items
- Set a trigger (e.g., Thank You page view or purchase confirmation)
Step 4: Test Your Implementation
Before relying on your event data, verify that events are firing correctly:
- Use GA4 DebugView to see real-time event tracking
- Use the GA4 Real-Time report to confirm events are being received
- Check the Google Tag Assistant or browser console for errors
Setting up proper GA4 event tracking takes time, but it’s an investment that pays dividends through better data quality and marketing insights.
Creating Custom Events in GA4
While automatic and recommended events cover many common scenarios, most businesses need custom events tailored to their specific user journeys and business objectives.
When to Create Custom Events
Consider creating custom events when:
- Tracking interactions specific to your business model
- Following user paths through proprietary features
- Measuring micro-conversions within your sales funnel
- Tracking engagement with specific content types
Custom Event Implementation Methods
| Method | Implementation | Use Case | Example |
|---|---|---|---|
| Google Tag Manager | Create GA4 event tags with custom triggers | Most custom interaction tracking | Tracking calculator usage, chatbot interactions, or form step completions |
| gtag.js Code | Direct code implementation using the gtag function | When GTM isn’t available | gtag('event', 'contact_form_submit', { |
| GA4 Event Creation UI | Create events based on existing events within GA4 interface | Simple derivative events | Creating a “valuable_download” event that fires when a specific file is downloaded |
Best Practices for Custom Event Naming
When creating custom events, follow these naming conventions:
- Use snake_case for event names (lowercase with underscores)
- Be descriptive but concise (action_object format works well)
- Stay consistent with your naming pattern across all events
- Avoid special characters and spaces
Good event names: video_completed, lead_form_submit, pricing_page_scroll
Poor event names: Click, Button 2, UserAction-Type3
Creating Events from Other Events
GA4 allows you to create new events based on existing events without additional code:
- Go to Configure → Events in your GA4 property
- Click “Create Event” and name your new event
- Define matching conditions based on existing events and parameters
- Add parameter modifications if needed
This feature is particularly useful for creating more specific events from broad automatically collected events. For example, creating a “newsletter_signup” event that fires when a form_submit event occurs with a specific form ID parameter.

Working with Event Parameters
Event parameters are additional pieces of information attached to events that provide context and detail. They’re essential for extracting meaningful insights from your event data.
Types of Parameters in GA4
| Parameter Type | Description | Examples |
|---|---|---|
| Standard Parameters | Common parameters that GA4 recognizes and uses in standard reports | currency, value, items, transaction_id, page_title, page_location |
| Custom Parameters | Parameters specific to your business needs | membership_tier, video_category, discount_code, user_preference |
| User Properties | Attributes associated with users rather than specific events | user_tier, account_type, subscription_status |
Custom Parameter Registration
Before you can use custom parameters in reports and explorations, you must register them as custom dimensions:
- Go to Configure → Custom Definitions
- Click “Create Custom Dimensions”
- Enter dimension name, description, and scope (event or user)
- Select the event parameter to register
GA4 limits you to 50 event-scoped and 25 user-scoped custom dimensions per property, so plan your parameter strategy carefully.
Parameter Value Limitations
Be aware of these limitations when working with parameters:
- Maximum of 100 unique parameters per event
- Parameter names limited to 40 characters
- Parameter values limited to 100 characters
- Use string, number, or boolean data types only
Strategic Parameter Usage
Use parameters strategically to enhance your analytics capabilities:
- Group related interactions under a single event type with differentiating parameters
- Include context relevant to business questions (who, what, where, when, how)
- Consider segmentation needs when defining parameters
- Balance detail with manageability to avoid parameter explosion
Example: Button Click Tracking Strategy
Instead of creating separate events for each button (login_button_click, signup_button_click, contact_button_click), use a single “button_click” event with a “button_name” parameter to differentiate between them. This approach is more scalable and keeps your event count manageable.
GA4 Event Reporting and Analysis
Collecting event data is only valuable if you can turn it into actionable insights. GA4 offers several ways to analyze your event data.
Standard Event Reports
GA4 provides several built-in reports for analyzing event data:
- Events report: Shows all events and their count
- Conversions report: Focuses on events marked as conversions
- Engagement report: Shows pages and screens with associated events
Creating Custom Reports with Explorations
The real power of GA4 event analysis comes through Explorations, which allow for deeper, more customized analysis:
| Exploration Type | Use Case | Event Analysis Capability |
|---|---|---|
| Free Form Exploration | Custom tabular analysis with multiple dimensions and metrics | Compare different events across various segments and time periods |
| Funnel Exploration | Analyzing multi-step conversion processes | Track event sequences and identify drop-off points |
| Path Exploration | Understanding user journeys through your site | See common paths users take between key events |
| Segment Overlap | Comparing user segments | Analyze how different user groups interact with key events |
Turning Events into Conversions
Not all events are equally important. Mark your key business outcomes as conversions:
- Go to Configure → Events
- Find the event you want to mark as a conversion
- Toggle the “Mark as conversion” switch
Marking events as conversions makes them available for use in conversion reports and campaign optimization.
Building Segments Based on Events
Create audience segments based on event behavior to analyze specific user groups:
- Engagement segments: Users who perform specific events
- Sequence segments: Users who perform events in a particular order
- Exclusion segments: Users who have not performed certain events
Extracting Marketing Insights from Events
Here are practical ways to use event data to inform marketing decisions:
- Campaign effectiveness: Compare conversion events across different marketing channels
- Content optimization: Analyze which content topics drive engagement events
- Feature adoption: Track how many users engage with new website features
- UX improvements: Identify pain points by analyzing drop-offs between sequential events
Migration Strategies: Moving from UA to GA4 Events
Transitioning from Universal Analytics to GA4 requires a thoughtful approach, especially when it comes to event tracking.
Event Tracking Differences Between UA and GA4
| Universal Analytics | Google Analytics 4 | Migration Considerations |
|---|---|---|
| Category, Action, Label, Value structure | Event name with parameters | Map UA categories and actions to GA4 event names and parameters |
| Events count against hit quota | No hit limit; event parameter limit instead | May need to consolidate some granular events |
| Goals configured in the admin | Conversion events marked in the events section | Recreate goals as conversion events |
| Custom dimensions and metrics at hit level | Event parameters registered as custom dimensions | Map custom dimensions to appropriate parameters |
Step-by-Step Migration Approach
- Audit existing events: Document all UA events currently in use
- Create a mapping document: Plan how each UA event translates to GA4
- Implement dual tracking: Run both UA and GA4 simultaneously during transition
- Prioritize business-critical events: Start with conversion and revenue tracking
- Update reporting references: Modify reports and dashboards to use new event structure
- Validate data accuracy: Compare event counts between systems
Example Event Mapping from UA to GA4
| Universal Analytics Event | GA4 Equivalent |
|---|---|
| Category: “Video”, Action: “Play”, Label: “Homepage Hero” | Event: video_play Parameters: { video_title: “Homepage Hero”, video_location: “homepage” } |
| Category: “Engagement”, Action: “Download”, Label: “Whitepaper-SEO-Guide” | Event: file_download Parameters: { file_name: “Whitepaper-SEO-Guide”, file_type: “pdf”, content_type: “whitepaper” } |
Common Migration Pitfalls to Avoid
- Direct translation: Don’t simply recreate UA’s category/action/label structure in GA4
- Data hoarding: Be selective about what you track; not everything needs to be an event
- Ignoring recommended events: Use Google’s standard event names when applicable
- Incomplete parameter registration: Don’t forget to register custom parameters as dimensions
- Historical comparisons: Understand that direct data comparisons between UA and GA4 may not be possible
Common Issues and Troubleshooting GA4 Events
Even with careful implementation, you may encounter issues with your GA4 event tracking. Here are solutions to common problems:
Events Not Appearing in Reports
If your events aren’t showing up in GA4 reports:
- Check DebugView: Verify events are being sent in real-time debug mode
- Verify implementation: Ensure your event code or tags are firing correctly
- Check for filters: Make sure you haven’t applied filters that exclude the data
- Allow for processing time: GA4 standard reports can take 24-48 hours to fully process
- Verify consistency: Event names are case-sensitive; “Add_to_cart” and “add_to_cart” are different events
Parameter Data Missing
If your event parameters aren’t available for analysis:
- Register custom dimensions: Parameters must be registered as custom dimensions to appear in reports
- Check parameter names: Verify parameter names match exactly in your implementation
- Verify value format: Ensure parameter values use supported data types
- Check character limits: Parameter names (40 chars) and values (100 chars) have size limits
Incorrect Event Counts
If your event data shows unexpected counts:
- Check for duplicate events: Multiple tags or code snippets might be firing the same event
- Verify triggering conditions: Events might be firing on unexpected interactions
- Check for sampling: Large data sets might be sampled in reports
- Understand thresholding: GA4 applies privacy thresholds that may affect small data sets
Debugging Tools and Techniques
These tools can help identify and fix event tracking issues:
- GA4 DebugView: See real-time event firing with detailed parameters
- Google Tag Assistant: Chrome extension that helps troubleshoot tag implementations
- GTM Preview Mode: Test tag firing without affecting production data
- Browser Console: Check for JavaScript errors that might prevent events from firing
- Network Tab: Monitor actual requests being sent to Google Analytics servers
Pro Tip: When troubleshooting, create a test property or stream to experiment with events without affecting your production data. This allows you to freely test without worrying about data quality issues.
Remember that GA4’s event tracking model is significantly different from Universal Analytics, so some challenges may simply require adjusting your expectations and approach to alignment with GA4’s design.
Frequently Asked Questions about GA4 Events
What’s the difference between events in Universal Analytics and GA4?
In Universal Analytics, events were just one of many hit types (pageviews, transactions, etc.) and followed a rigid category/action/label/value structure. In GA4, everything is an event, including pageviews, and events consist of a name and optional parameters that provide additional context.
Is there a limit to how many events I can track in GA4?
GA4 doesn’t have a hit limit like Universal Analytics did. However, there are some operational limits: up to 500 distinct event types per property, up to 25 user-scoped custom dimensions, and up to 50 event-scoped custom dimensions per GA4 property.
Do I need to use Google Tag Manager with GA4?
While not strictly required, Google Tag Manager (GTM) makes implementing and managing GA4 events much easier, especially for marketers without direct access to website code. GTM allows you to add, modify, and remove event tracking without developer intervention.
How do I track form submissions in GA4?
GA4 doesn’t automatically track form submissions. You can implement this using GTM by creating a Form Submission trigger and a GA4 event tag. Alternatively, you can use custom code to fire an event when forms are submitted. For key forms, consider using the recommended event “generate_lead” with appropriate parameters.
Can I use the same events for both web and app tracking?
Yes! One of GA4’s strengths is its unified data model across platforms. You can use the same event names and parameters for both web and app interactions, making cross-platform analysis much easier than it was with Universal Analytics.
How do I know which events to track?
Start by identifying key user journeys and business objectives. Track events that represent meaningful user interactions, progress toward conversion, or important business outcomes. Focus on quality over quantity and prioritize events that will actually inform your marketing decisions.
How do I turn events into conversions?
In GA4, you can mark any event as a conversion by going to Configure → Events, finding the event in your list, and toggling the “Mark as conversion” switch. This will include the event in conversion reports and allow it to be used for optimization in connected advertising platforms.
Can I create events without updating my website code?
Yes, GA4 offers three ways to create events without changing code: 1) Enable enhanced measurement events in the GA4 interface, 2) Create modified events based on existing events, or 3) Implement events through Google Tag Manager using built-in triggers and variables.
Taking Your GA4 Event Tracking to the Next Level
Mastering GA4 events is no small task, but it’s essential for modern marketing measurement. The event-based model offers unprecedented flexibility and cross-platform tracking capabilities that, once properly implemented, can transform your marketing analytics.
Remember these key takeaways:
- In GA4, everything is an event, creating a simpler but more powerful data model
- Start with automatic and enhanced measurement events before building custom events
- Use event parameters strategically to add context without creating event sprawl
- Leverage GA4’s Exploration tools to analyze event sequences and user journeys
- Migrate from UA methodically, rethinking your approach rather than simply recreating old events
Implementing proper GA4 event tracking requires both technical knowledge and strategic thinking about what data will actually drive business decisions. Many businesses find this challenging to manage internally, especially while adapting to GA4’s many other changes.
At Daniel Digital, we specialize in implementing strategic GA4 measurement frameworks that focus on capturing meaningful business insights rather than vanity metrics. Our approach ensures you’re tracking what matters while maintaining data quality and compliance with evolving privacy standards.
