Google Analytics 4 (GA4) is a bit different from Universal Analytics (UA) when it comes to setting up goals. In GA4, what were previously known as "goals" in UA are now referred to as "conversions". Here's a step-by-step guide on how to set up conversions (goals) in GA4:
Step 1: Navigate to your GA4 property then click 'Admin'
Step 2: Select 'Events' from property settings
Step 3: Turn the switch on to mark any event as conversion. If you don't see your event in the events tab, you can follow the next step to add a custom event.
Step 4: Go back the property settings and select 'Conversions'
Step 5: Click 'New Conversion Event'
Step 6: Enter the name of the event that you want to track as a conversion. This should match the event name that you're sending to GA4. For example, if you're tracking form submissions, you might have an event named "form_submit" that you would enter here.
Step 7: After creating the conversion event, you should test it to make sure it's working correctly. You can do this by triggering the event on your website and then checking in GA4 to see if the conversion is recorded.
Remember, GA4 is event-based, so you'll need to be sending the appropriate events to GA4 in order to track conversions. This might require additional setup on your website or in your app.
Also, note that GA4 automatically tracks some events as conversions by default, such as "first_visit", "session_start", and "purchase". You can choose to turn these off if they're not relevant to your goals.
