Google Analytics 4: How to Set Up Your First Conversion Goals

Why Conversion Tracking in GA4 Is Non-Negotiable

If you are running a website without conversion tracking, you are essentially flying blind. Google Analytics 4 (GA4) has fundamentally changed how conversions work compared to the old Universal Analytics. The good news? The new system is more powerful and more flexible—once you know how to set it up.

According to Google, over 14 million websites now use Google Analytics. Yet studies suggest that nearly 40% of businesses still do not track conversions properly. That means almost half of all website owners have no reliable way to measure ROI.

Let’s fix that.

Understanding the GA4 Event-Based Model

From Goals to Events

In Universal Analytics, you created “goals”—destination URLs, time-on-site thresholds, or specific events. GA4 scraps that entire framework. Now, everything is an event. Page views, scrolls, clicks, form submissions, purchases—all events.

To create a conversion, you simply mark an event as one. No more juggling four different goal types.

Automatically Collected vs. Custom Events

GA4 provides three categories of events:

• Automatically collected events – page_view, session_start, first_visit
• Enhanced measurement events – scroll, outbound_click, file_download, video_start
• Custom events – anything you define yourself, like form_submit or add_to_cart

Conversions are built on top of these events.

Step-by-Step: Setting Up Your First Conversion

Step 1 — Identify What Matters

Before touching GA4, define what a conversion means for your business. Common examples include:

• A completed purchase (ecommerce)
• A contact form submission (lead generation)
• A newsletter signup
• A phone call click on mobile

For most service-based businesses, a form submission or a quote request is the primary conversion. For ecommerce stores, it is the purchase event.

Step 2 — Mark an Existing Event as a Conversion

This is the simplest method:

1. Go to Admin → Events in your GA4 property.
2. Find the event you want to track (e.g., form_submit).
3. Toggle the “Mark as conversion” switch to on.

That’s it. GA4 will now count every occurrence of that event as a conversion.

Step 3 — Create a Custom Event (When Needed)

If the event you need does not exist yet, create one:

1. Navigate to Admin → Events → Create Event.
2. Name your new event (e.g., generate_lead).
3. Set matching conditions. For example:
   • event_name equals page_view
   • page_location contains /thank-you
4. Save, then mark this new event as a conversion.

This approach is perfect for tracking thank-you page visits after a form submission.

Step 4 — Validate with Real-Time Reports

Never assume your setup works. Open the Real-time report in GA4, trigger the conversion yourself (submit the form, complete a test purchase), and confirm the event appears. This takes 30 seconds and saves hours of debugging later.

Common Mistakes to Avoid

• Tracking too many conversions — if everything is a conversion, nothing is. Stick to 5–8 meaningful actions.
• Forgetting cross-domain tracking — if your checkout or form lives on a subdomain, configure cross-domain measurement or you will lose attribution data.
• Ignoring the 24–48 hour delay — GA4 standard reports can take up to two days to fully process. Do not panic if numbers look low immediately.

At Lueur Externe, our analytics specialists frequently audit GA4 setups for clients and find that roughly 60% of properties have at least one misconfigured conversion. A small error in event naming or condition matching can silently break your entire reporting.
