Track Custom Events Using Javascript

Developers can track and send custom events programmatically to Google Analytics by utilizing the track() method of the GoogleAnalyticsTracker object.


The track() method accepts 3 arguments: The form's ID (Integer), the event label (String) and an optional callback (Function) to verify the event has been successfully tracked.

ConvertForms.GoogleAnalyticsTracker.track(form_id, event_label, function(success));

Track Field Focus Event

The example below fires the event "Email Focused" when the user focuses on the field email of the form #4.

window.addEventListener("DOMContentLoaded", function() {
    var input = document.querySelector('#cf_4 input[name="cf[email]"]');
    input.addEventListener("focus", function() {
        ConvertForms.GoogleAnalyticsTracker.track(4, 'Email Focused');

Frequently Asked Questions

What are the requirements to use the Google Analytics Tracker?

You need an active Google Analytics account and Convert Forms Pro v2.3.0 at least.

How to verify that Google Analytics Tracker is working

To verify that the form events are successfully tracked, just log in to your Google Analytics account, click on the Real-Time section on the left and check if the events are coming well in the report.

Will this increase the loading time of my site?

The Google Analytics Tracker has no impact on the page speed because all the requests are asynchronous, meaning that the browser will continue to load and your users will not see any delay whatsoever.

What about GDPR (General Data Protection Regulation)?

The Google Analytics Tracker does not collect or send any personal information or form submissions to Google Analytics. The only form-related information sent is the name of the form.

Where can I see the events in Google Analytics?

There are two places that show events in Google Analytics.

  • The real-time dashboard under Events section where an event should show up here in (almost) real-time.
  • The full report can be found under Behavior > Events. Note that it can take up to 24 hours to show up in this section.

I have noticed that some events are missing in my Google Analytics account, compared to my backend numbers.

Possible reasons for not getting the accurate events are as below:

  • If any javascript error is detected on the page may restrict tracker's code to get executed further.
  • Some browsers and common ad-blocking programs block certain JavaScripts (including GA's script), which means Google Analytics is unable to record events.
  • The user has left the page before the event has had a chance to send to Google Analytics.

Additionally, Google Analytics is a trend analysis tool, and as such cannot be expected to be 100% accurate. However, if the variance is greater than 10-12%, there might be an issue with the coding!
