Turn your GTM events into real goals (GA4 & Meta)

You have successfully imported your pre-configured GTM file and embedded the script into your application codebase. But you're not quite at the finish line yet!

Google Tag Manager's only job is to *send* data out when a user interacts with your site (clicking an email link or submitting a form). You still need to explicitly tell Google Analytics 4 and Meta that these specific incoming events are goals/conversions. Ad algorithms cannot optimize your budgets until this step is done.

Test first

Before you map out conversions inside the ad platforms, make sure your dataLayer is receiving data correctly:

• GTM Preview mode initializes and shows a Connected status.
• Accept cookies in your banner (so Consent Mode updates to allowed).
• Complete a test form submission or click a phone link on your preview tab.
• Check that the event (e.g. `generate_lead`) appears in your GTM Preview timeline.
• Verify that the event registers inside the Realtime report in GA4.

Once this checklist passes, you're ready to lock in your conversion configurations.

Part 1: Mark events as conversions in Google Analytics 4 (GA4)

When GTM Navigator triggers a form submission, it lands as an event in your GA4 property. To mark it as an official conversion goal:

• Log into Google Analytics.
• Click on Admin (the gear icon in the bottom left corner).
• Under *Data collection and modification*, click on Events.
• You'll see a list of all events your site receives (e.g. `generate_lead`, `phone_click`, `email_click`).
• Locate your desired lead event and toggle the switch on under the Mark as conversion column.

“If your event is brand new, it can take up to 24 hours to appear in GA4. You can bypass the wait by going to the "Conversions" tab, clicking "New conversion event," and typing the exact event name (e.g. generate_lead).”

Part 2: Set up Custom Conversions in Meta (Facebook)

To ensure the most robust data matching in Meta, we use event-based rules instead of fragile URL parameters that change during site updates.

• Go to your Meta Events Manager dashboard.
• Click Custom Conversions in the left-hand navigation menu.
• Click the blue Create Custom Conversion button.
• Give your goal a descriptive name (e.g. *Form Submission (Tag Navigator)*).
• Choose your data source (your Meta Pixel / Dataset ID).
• Under *Event*, select Lead or your custom event name.
• Under Rules: select Event Name = `generate_lead` — or e.g. lead_type = `Quote request` if you segmented your forms.
• Add value: If you assigned a financial value to your lead, enter that exact amount (e.g. 50 USD) to track ROAS in Ads Manager.
• Click Create.
