Google Analytics 4 - How to make key events

When Conversion Bridge sends data to Google Analytics 4, it automatically matches each event to one of Google's recommended event names. This is why Google Analytics custom labels are not used — your data works with GA4's built-in reporting tools right out of the box.

However, you may notice that GA4 groups all events of the same type together. For example, all form submissions appear as a single form_submit event. If you only have one form on your site, this is fine. But if you have multiple forms, you probably want to see each one separately.

The good news is that Conversion Bridge sends detailed data with every event — including the form's unique ID and title. You can use this data to create custom events in GA4 that separate your forms (or any other events) into individual entries.

Step 1: Create a Custom Dimension

Before you can filter events by form ID or title, you need to tell GA4 about those data fields.

1. In Google Analytics, go to Admin → Custom Definitions
2. Click the Create custom dimension button
3. Enter ID as the Dimension Name
4. Select id from the Event Parameter dropdown
5. Click Save
6. (Optional) Repeat to add a second dimension — enter Title as the name and select title as the event parameter

Step 2: Create a Custom Event

Now you can create a new event that filters for a specific form.

1. In Google Analytics, go to Admin → Events
2. Click the Create event button
3. Click Create
4. Enter an Event Name — this must be all lowercase with no spaces (for example, contact_form)
5. Under Matching conditions, set event_name equal to form_submit
6. Click Add condition
7. Set the Parameter to id and the Value to the unique ID of your form

The form ID will depend on your form plugin. Check your form plugin's settings to find the ID for the form you want to track.

Note: Your new custom event may not appear right away. Submit a test form to trigger the event, then check the Realtime report to see it. It can take up to 48 hours for new events to appear in standard reports.

Step 3 (Optional): Mark as a Key Event

If your new custom event is important to your site's success, you should mark it as a Key Event. Google Analytics gives Key Events special treatment, including dedicated columns and extra reporting features.

To mark an event as a key event:

1. In Google Analytics, go to Admin → Key Events
2. Click the New key event button
3. Enter the name of your event (for example, contact_form)

You can also mark events as key events from the Admin → Events page by toggling the key event switch next to any event that has started tracking.

Automatic Custom Dimensions with OAuth

If you connected Google Analytics to Conversion Bridge using the OAuth method, Conversion Bridge can automatically create custom dimensions in your GA4 property. This means you may not need to manually create the ID and Title dimensions described in Step 1 — they may already be set up for you.

Conversion Bridge automatically creates custom dimensions for:

• Pageview properties you enable in settings (like author, category, tags, post type, and more)
• User properties sent by your plugin integrations (like membership plans)

These dimensions are created automatically when you:

• First connect via OAuth
• Enable new properties and save your settings
• Update the plugin (any missing dimensions are added)
