GA4 planning guide

Your Website Domain Required

Use the domain where the click starts. Do not include a page path unless you need it for your own notes.

External Destination URL Required

This must be the outside website people reach after clicking the link.

Link or Button Label

Click Purpose Required

Tracking Method Required

Use Enhanced Measurement when you only need to know which external links were clicked. Use custom tracking when the click is commercially important or should become a key event.

Recommended setup

Start with the details above

Enter the domain where the click starts and the external URL where the click sends visitors. The tool will tell you whether default GA4 tracking is enough or whether to create a custom event.

Custom gtag.js snippet

Choose the lightest tracking that answers the business question.

GA4 can track many outbound links automatically. Custom tracking is useful when the click represents a meaningful business action, not just another external URL.

Use default GA4

Good for broad visibility into external links when Enhanced Measurement is enabled and the link is a normal anchor tag.

Use custom events

Better for booking links, partner referrals, checkout starts, demo requests, or clicks you may want to mark as key events.

Test before launch

Click the link yourself, confirm GA4 receives the event, and verify the destination opens as expected.

Where to find outbound clicks in GA4.

GA4 Enhanced Measurement records outbound clicks as the event named click. The useful details sit in link dimensions like Link URL, Link domain, and Outbound.

Check default outbound clicks

1Open GA4 and go to Explore.
2Create a blank exploration.
3Add dimensions: Event name, Link URL, Link domain, and Outbound.
4Add the metric Event count.
5Filter Event name to click and Outbound to true.

If no outbound clicks appear, check that Enhanced Measurement and Outbound clicks are enabled in the web data stream.

Validate a custom event

1Open GA4 DebugView or Realtime.
2Click the outbound link on the website.
3Look for your custom event name, such as outbound_calendar_booking_click.
4Confirm the parameters are useful: link URL, link domain, link text, and click type.
5Mark the event as a key event only when the click represents a meaningful business outcome.

Avoid sending private client details or sensitive URL parameters into GA4 event parameters.
