In today's fast-paced digital world, knowing how users interact with your website is essential. It helps you optimize the user experience and boost conversions. Custom event triggers offer a strong method to track these interactions beyond the usual techniques. They let you gather valuable insights tailored to your specific needs.
In this post, we'll explore what custom event triggers are, why they are essential, and how to implement them effectively. This way, you can successfully capture important user actions on your site.
What is a Custom Event Trigger?
A custom event trigger is a feature in tools like Google Tag Manager that tracks website or mobile app interactions that normally go unnoticed. A typical use case is monitoring form submissions. However, if you change the default behavior of a form, such as overriding the submit event, custom event triggers become necessary for accurate tracking.
These triggers allow you to capture specific actions users take, giving you deeper insights into their behavior.
Why Use Custom Event Triggers?
Integrating custom event triggers into your tracking strategy offers several benefits:
Flexibility: Unlike standard tracking, custom event triggers let you focus on specific actions that are crucial for your business. For example, if you run an e-commerce site, tracking product views can provide insights into popular items.
Enhanced Insights: Tracking unique interactions can reveal user preferences and behavior. For instance, a study showed that websites using custom tracking increased their conversion rates by up to 20 percent.
Reliable Data: Custom triggers ensure that even if standard events do not apply, you still capture relevant activities. This reliability can improve data accuracy, which is essential for making informed decisions.
Improved Conversion Tracking: Custom event tracking helps you link actions like button clicks or downloads directly to conversions. For instance, if 30 percent of users who click a "Download" button end up making a purchase, that data is invaluable for refining your marketing strategy.
How to Create a Custom Event Trigger
Creating a custom event trigger is straightforward and can be accomplished in just a few steps:
Click on Triggers and select New.
Choose Trigger Configuration and select the Custom Event trigger type.
Enter a relevant event name. Using "use regex matching" allows you to catch multiple variations of an event.
Example Configuration
For example, if you want a tag to fire when a custom event named `button1-click` is pushed to the data layer, first add the following code to push the event when the designated button is clicked:
```html
<a href="#" name="button1" onclick="dataLayer.push({'event': 'button1-click'});">Button 1</a>
```
Next, create a new custom event trigger in Google Tag Manager:
Event name: `button1-click`
This trigger fires on: All Custom Events
Once the button is clicked, the `button1-click` event is sent to the data layer. Google Tag Manager detects this value and fires the associated tag, even if the default submit event has been overridden.
Sending Multiple Variables with dataLayer.push()
To enhance the data you are collecting, you can also send multiple variables with your custom event. For example, if you want to track a conversion value linked to the event name, your code can look like this:
```javascript
dataLayer.push({'event': 'button1-click', 'conversionValue': 25});
```
Here, the `conversionValue` of 25 is recorded alongside the event. Next, create a corresponding data layer variable in Google Tag Manager to use in your conversion tracking, such as for Google Ads. This setup allows you to effectively measure how specific actions boost your conversion goals.
Best Practices for Custom Event Tracking
Implementing custom event triggers effectively can be challenging. However, following these best practices can streamline the process:
Use Clear Naming Conventions: Use intuitive names for your custom events to identify their purposes easily. For example, instead of a vague name like `event1`, use something descriptive like `signup-button-click`.
Test Before Publishing: Always test your custom events in a safe environment before live deployment. This ensures the data is recorded correctly and helps you avoid issues.
Document Your Triggers: Keep detailed records of your custom triggers and events. This is beneficial for future team members or when you revisit your analytics later.
Monitor Performance: Regularly review the data from your custom triggers to ensure they stay pertinent as your site changes. Adjust them as needed to keep insights accurate.
Integrate with Other Tools: Combine the capabilities of other analytics tools with your custom events. This gives you a comprehensive view of user interactions and their effects.
Take Action and Transform Your Tracking Strategy
Custom event triggers are a vital part of modern site tracking. They enable you to go beyond standard methods to identify specific user interactions. This technology allows you to collect actionable insights, improve user experiences, and drive conversions effectively.
Now that you know the importance and functionality of custom event triggers, it’s time to get started. With a few simple steps, you can establish an effective tracking setup tailored to your website's unique needs.
Embrace custom event tracking and unlock a data-driven approach to decision-making for your site.

By incorporating these strategies into your approach, you can enhance your understanding of user behavior. This, in turn, will lead to a more optimized experience for your audience. Happy tracking!
