Google Analytics is a powerful tool that helps you understand your website's performance and make data-driven decisions. It provides a wealth of information, but only if you know how to use it.
One of the most important aspects of Google Analytics is tracking key events, which allow you to measure specific interactions on your website. These events can be anything from button clicks to form submissions.
To track events, you need to set up event tracking in your Google Analytics account. This involves setting up a tracking code on your website and specifying the events you want to track.

Setting Up Google Analytics 4
To set up Google Analytics 4, you'll need to navigate to the Admin section and select Events under Data Display. From there, you can mark an existing event as a Key Event.
There are two main ways to do this: marking an existing event or creating a new one. If you need to remove a Key Event later, just click the star icon again, and it will go back to being a regular event.
To mark an existing event, find the event you want to track in the Recent Events tab, click the star icon on the left, and a filled star will indicate it's now a Key Event.

Understanding Conversions
Conversions are a crucial metric in Google Analytics, and now they're being called Key Events. Key Events measure important actions on your website, like purchases or newsletter subscriptions, and are used to track the success of your business. These actions are now called Key Events in Google Analytics 4.
You can report on the same conversion counts between Google Ads and Analytics by creating Google Ads conversions based on Key Events. This provides a consistent way of measuring important actions and reduces the risk of data discrepancies between Google Ads and Google Analytics.
Here are some key characteristics of Key Events:
- They measure specific behavioral interactions on your website or app.
- They can be marked as important to your business and appear in Analytics reports.
- They aren't directly eligible for reporting or bidding in Google Ads.
Key Events are created and reported like previous conversions in Google Analytics, and you don't need to take any action on your existing setup.
Do I Need to Reconfigure Existing Conversions?
If you previously marked Conversions in your GA4 property, you're in luck – Google has automatically updated them for you.
Google has automatically updated all of your existing Conversions and renamed them as Key Events.
You can review them by navigating to 'Admin' and selecting 'Events' under 'Data Collection' in your GA4 property.
However, if you want to add or remove any Key Events, you can do this manually.

What Are Conversions?

Conversions are a crucial interaction you want your visitors/users to complete. They can be split into micro and macro conversions. A micro-conversion can be a newsletter subscription, a download of a whitepaper, etc. These actions put your visitors/users one step closer to the main (macro) conversion, such as a purchase.
In Google Analytics 4 (GA4), these important actions are now called Key Events. Key Events measure visitors completing an important action, and they still measure the same thing as conversions. You can create a segment of your users who have made a purchase and then try to understand their behavior.
Key Events are created and reported like previous conversions in Google Analytics. They are an event that you mark as important to your business, and they appear in Analytics reports. However, they aren't directly eligible for reporting or bidding in Google Ads.
A macro conversion is a more significant interaction, such as a purchase. By tracking Key Events in GA4, you can better understand what does and doesn't work for your business. You can create a segment of your users who have made a purchase and then try to understand their behavior, and use this information to optimize your marketing strategies.
Here are some examples of Key Events:
- Purchase
- Newsletter subscription
- Download of a whitepaper
- Any other important action you want to track
These Key Events can be used to measure the effectiveness of advertising campaigns through conversions and then redistribute your advertising budget.
Working with Events
To mark an action as a Key Event in Google Analytics 4, you have two options. You can either mark an existing event by clicking the star icon next to it, or create a new event and enable the "Mark as key event" option.
There are key differences between Key Events and conversions in Google Analytics 4. Key Events are events that you mark as important to your business, and they appear in Analytics reports but aren't directly eligible for reporting or bidding in Google Ads.
You can create up to 30 key events in Google Analytics 4, which is more than the 20 goals allowed in Universal Analytics. Additionally, Google Analytics 4 automatically provides anomaly detection and predictive insights, which can be useful for identifying trends and patterns in your data.
Here are some examples of key events that you might want to track:
- Scroll to 90% of a blog post or article
- Play at least 50% of a product video
- Complete a tutorial
- Download a white paper
- Subscribe to a newsletter
- Complete a registration form
- Begin the checkout process
- Add merchandise to the shopping cart
- Make a purchase
By tracking these key events, you can get a better understanding of how users are interacting with your website and identify areas for improvement.
Set Up Guide

To set up key events in Google Analytics, you can mark an existing event or create a new one. There are two main ways to do this.
First, navigate to the 'Admin' section and select 'Events' under 'Data Display.' You can then find the event you want to track and click the star icon on the left to mark it as a Key Event. A filled star means it's now a Key Event.
Alternatively, if the event you want to track doesn't exist yet, you can create it manually. To do this, navigate to 'Admin' and select 'Events' under 'Data Display,' then click 'Create Event.' Give your event a clear name, such as 'generate_lead,' and enable the 'Mark as key event' option.
Here are the steps to create a new key event:
- Navigate to 'Admin' and select 'Events' under 'Data Display.'
- Click 'Create Event.'
- Give your event a clear name.
- Enable the 'Mark as key event' option.
- Define the matching conditions.
- Save your new event.
Once you've set up your key events, you can use them to create Google Ads conversions, which can help you report on the same conversion counts between Google Ads and Analytics.
Improve Event Naming Convention
Planning your event naming convention is crucial for easy key event creation. It's especially important for beginners, as it makes a huge difference in the long run.
You can create more distinct events by planning ahead. For example, instead of tracking all form submissions with the event name "form_submission", you can create separate events for contact form submissions, search form submissions, and registration form submissions.
Here are some examples of distinct events:
- contact_form_submission
- search_form_submission
- sign_up
This requires a more thorough plan upfront, but it's worth it for a solid setup.
Default Value
Assigning a default monetary value to a key event can be a game-changer for understanding the impact of your online activities.
You can set a default key event value in the key event's settings, which is a monetary value assigned to a specific action, like a new form submission worth $2.
This value won't affect your historical data, so you can experiment without worrying about altering past results.

If you're already sending a "value" parameter to GA4 with the event, that parameter will take priority over the default value you set.
The default value won't populate revenue-related metrics in GA4, but it will show up in the Event value metric instead.
Here are some key points to keep in mind when working with default key event values:
- Changing this value won't affect your historical data.
- If you're already sending a "value" parameter to GA4 with the event, that parameter will get a higher priority than the default value.
- This "value" will populate the Event value metric in GA4.
New Rate Metrics
Google Analytics 4 (GA4) has introduced a new metric called key event rate, which compensates for the lost conversion rate metric. This change is a big deal for marketers and analysts.
GA4's key event rate metric helps you measure the rate of key events, providing a more accurate picture of your website's performance. It's a game-changer for those who relied on conversion rate metrics in earlier versions of GA4.
Two parties benefit from separating conversions and key events in GA4: marketers and analysts. This separation allows for more precise measurement and reporting.
Here's an interesting read: Sharing Events on Google Calendar
By separating conversions and key events, GA4 now owns one of the most popular marketing metrics. It's a testament to the platform's evolution and commitment to providing valuable insights.
Here's a summary of the benefits of creating Google Ads conversions from key events:
- Report on the same conversion counts between Google Ads and Analytics
- Report on non-Google and organic channels, including channels that are part of the same cross-channel campaign
- Bid against the conversions in your ad campaigns
- Build audiences for re-marketing purposes
What's New in GA4
In GA4, key events have replaced the old conversion rates you might remember from earlier versions of GA4.
Google changed the name to key events, but that's not all - it completely changed the game. This change provides consistency across tools while improving how marketers and analysts report on performance.
The benefits of introducing key events in GA4 include additional conversion reporting and tools that will launch in the advertising section in the future.
Key events are now used in Google Analytics, but they're still called Conversions when imported from Google Analytics into Google Ads.
Here's a quick rundown of the change:
- Key events are used in Google Analytics.
- Conversions are still used in Google Ads when imported from Google Analytics.
Aligning with Business Objectives
Aligning key events with business objectives is crucial for measuring success. This involves reporting on specific actions users take after interacting with your content.
If your chief marketing officer is focused on raising brand awareness, report on key events such as organic search users scrolling to 90% of a blog post or article, playing at least 50% of a product video, or completing a tutorial.
For a chief revenue officer focused on generating leads, report on key events like organic search users downloading a white paper, subscribing to a newsletter, or completing a registration form.
If your chief executive officer is focused on driving online sales, report on key events such as organic search users beginning the checkout process, adding merchandise to the shopping cart, or making a purchase.
You can even assign a default monetary value to a key event in GA4, which makes tracking and measuring even more effective.
By aligning key events with business objectives, you can provide valuable insights to your executives and make data-driven decisions that drive business growth.

Creating Conversions
You can assign a default monetary value to a key event in GA4, which is a game-changer for advertisers.
This value will not affect your historical data, but it will help you understand the economic value of a key event.
If you're already sending a "value" parameter to GA4 with the event, that parameter will get a higher priority than the default value you entered in the settings.
To set the default key event value, go to Admin > Data Display > Key events and locate the key event, then click the three dots next to it and select "Set default key event value".
You can use this feature to assign a monetary value to any key event, not just purchase events.
For example, if 10% of people who sign up for a newsletter go on to become customers and your average transaction is $500, then you can associate $50 (10% of $500) as the monetary value of this key event.
By doing this, you can see the economic value of a key event, such as the number of organic search users who go on to make a purchase.
Here's a list of key events that can be reported for different business objectives:
- B2C company: organic search users who scroll to 90% of a blog post or article, play at least 50% of a product video, or complete a tutorial.
- B2B company: organic search users who download a white paper, subscribe to a newsletter, or complete a registration form.
- Ecommerce: organic search users who begin the checkout process, add merchandise to the shopping cart, or make a purchase.
By creating conversions based on key events, you can report on the same conversion counts between Google Ads and Analytics, and bid against the conversions in your ad campaigns.
Finding Events in GA4
To see all the GA4 events that are marked as key events, go to Admin and then click Key Events of the Data Display section. This will give you an overview of all events that are marked as worth tracking for your business.
You can also see basic data for the selected period in the Key Events report. For example, if you see a screenshot of the generate_lead event performing 100% better than in the previous period, it's likely a key event.
The Key Events report is located in the Admin section, under Data Display. From there, you can navigate to Key Events to view the report.
To access the Key Events report, you'll need to have administrator or editor rights for the GA4 property.
Here's a quick rundown of how to find events in GA4:
- Go to Admin
- Click Key Events under Data Display
- View the report to see all marked key events
By following these simple steps, you'll be able to find and view key events in GA4, giving you a better understanding of your business's performance.
How Are They Different?

Key events in Google Analytics 4 (GA4) are a game changer, and understanding the difference between them and other events is crucial. They're given special treatment in reports, which means they show up in metrics like 'User Key Event Rate' and 'Session Key Event Rate'.
These metrics are calculated based on the total number of key events triggered, users with a key event, and sessions with a key event, respectively. The User Key Event Rate is calculated as users with a key event divided by total users, and the Session Key Event Rate is calculated as sessions with a key event divided by total sessions.
To illustrate the difference, consider this: all events in GA4 represent user activity, but key events are marked as important to your business. This means they're not directly eligible for reporting or bidding in Google Ads.
Here's a summary of the key differences:
Remember, key events are created and reported like previous conversions in Google Analytics, but they're not directly eligible for reporting or bidding in Google Ads. This means you can use them to measure the performance of your site and marketing campaigns, even if you don't use Google Ads.
Viewing and Reporting
You can use Google Analytics reports and explorations to count the number of times users trigger key events and attribute credit to different touchpoints along a user's path to triggering key events.
The key event data is available in various places on the Google Analytics 4 interface, depending on the information you’re looking for. You can view key event data in Google Analytics 4 reports, and it's a great way to track user behavior and conversion rates.
If you've marked a key event as a conversion, the conversion data will show records from the time it was marked, not just from the time it was triggered. For example, if you created a pdf_download event in January and marked it as a conversion in March, the conversion data will show records from January.

Viewing Reports Data
You can view key event data in various places on the Google Analytics 4 interface, depending on the information you're looking for. The key event data is available in Acquisition reports, Engagement reports, Exploration reports, and Advertising reports.

In the Acquisition reports, you can compare which channels bring in the most valuable users by using the Key Events columns. This is especially useful in the 'Traffic Acquisition' report, where you can compare conversion performance across different traffic sources.
Key Events appear in the Key Events columns of these reports, allowing you to see how often people take important actions. You can also use the Key Events columns to identify which channels bring in the most valuable users.
You can also view key event data in Exploration reports, which allow you to build custom reports combining 'Key Events' with dimensions like 'Landing Page' or 'Session Campaign'. For example, you can combine the Default Channel Group and Landing Page dimensions with Key Event metrics.
Key Events are also available in Advertising reports, where you can measure campaign performance against your top interactions. This is useful for seeing how well your campaigns are performing against key events like purchases.
Here are some key reports where you can view key event data:
- Acquisition reports
- Engagement reports
- Exploration reports
- Advertising reports
View Counts
View Counts can be a valuable way to understand user behavior on your website or app. Many Google Analytics reports include a Key events column that displays the number of times users triggered key events.
To see these counts, you can view the Landing pages and User acquisition reports, which both feature the Key events column. This column separates key event counts by dimension values.
You can narrow down the counts by selecting a specific key event from the All events menu. This lets you view the number of times users triggered that key event.
To further investigate key event counts, you can build your own explorations using key event metrics like Key events and Session key event rate.

New features for advertisers, including additional conversion reporting and tools, will launch in the advertising section.
To make the most of GA4, it's essential to understand how key events work and how they can benefit your business.
In the future, new features for advertisers will launch in the advertising section.
GA4 Setup and Configuration
Setting up Google Analytics 4 (GA4) requires some configuration to get the most out of Key Events. To start, you'll need to create a new GA4 Event tag in Google Tag Manager (GTM).
In GTM, create a new GA4 Event tag and enter an event name, such as 'generate_lead'. This will help you track custom actions that GA4 doesn't track automatically. You can also add event parameters like form type or button text to provide more context.
Related reading: Ga4 Utm Parameters
To trigger the event, you'll need to create a trigger for the action you want to measure. For example, you can create a trigger for a click on a specific button or a "thank you" page view.
Here's a step-by-step process to set up your GTM-based events:
- Create a new GA4 Event tag in GTM.
- Add event parameters as needed.
- Create a trigger for the action you want to measure.
- Test in Preview mode to ensure the tag fires correctly.
- Publish your changes in GTM.
- Mark the new event as a Key Event in GA4.
Once configured, your GTM-based events will appear in GA4 reports as Key Events, giving you valuable insights into your website's behavior.
Troubleshooting and Debugging
To troubleshoot and debug Google Analytics 4 key events, start by checking the data in the DebugView. This is where your debugging should take place, not in the GTM Preview and Debug mode.
The DebugView can be found in the Admin section of the GA4 interface, under Data display. To enable the debug mode, simply have the GTM Preview mode enabled or install the Google Analytics Debugger Chrome extension.
Ensure you've selected the correct Debug device in the top left corner, as multiple devices may be listed if multiple visitors have enabled the debug view.
Suggestion: How to Plot Multiple Places on Google Maps
Events in the DebugView are marked with blue icons, while key events are marked with green icons. Verify that your custom events are set up correctly and have the green flag icon.
To test key events, take the action on your site and then check in the real-time report if GA4 detects and shows the key event. This will ensure that Google Analytics registers it correctly.
Regularly auditing your GA4 property and focusing on key events is crucial, especially when working in a team. This will help prevent losing vital business data.
Double-counting can occur when events trigger on a specific page location, such as when users refresh the URL. To avoid this, review your data and adjust your event setup accordingly.
In one instance, a user experienced double-counting with 46 events from 9 users, which was actually a conversion.
