Your Conversions Aren't Real Until You Verify Them

Last Tuesday, I got an urgent Slack message from a client: "We've been running Google Ads for three weeks and GA4 shows zero conversions." Turns out, their ga4 conversion setup verification was never completed after a theme update pushed new code to their checkout page. Three weeks. Over $6,200 in ad spend firing into a black hole.

This happens way more than you'd think.

We've audited dozens of GA4 setups this year, and roughly 42% of them have at least one conversion event that isn't firing correctly. Not broken in an obvious way, either. The events show up in DebugView, they look fine in the Realtime report, but the actual conversion counting is off because of duplicate triggers, missing parameters, or wrong event names.

The Three-Minute GA4 Conversion Setup Verification Check

You don't need an hour for this. Open your GA4 property, head to Admin, then Conversions. Look at every event marked as a conversion. Now open Google Tag Assistant in another tab and walk through your funnel yourself.

Here's what you're checking:

  • Does the conversion event fire exactly once per actual conversion?
  • Are the event parameters (value, currency, transaction_id) populated correctly?
  • Is the event name an exact match between your tag and the GA4 conversion settings?
  • Do test transactions in GA4 DebugView show the right data?

I can't tell you how many times I've found a mismatch between "purchase" and "Purchase" that silently broke everything. GA4 event names are case-sensitive, and that trips people up constantly.

Where GA4 Conversion Setup Verification Usually Fails

The sneakiest failures aren't total breakdowns. They're partial ones. Your event fires on desktop but not mobile. Your form submission event triggers on page load instead of actual submissions because someone copied a GTM trigger wrong.

Picture this: you're running a Father's Day campaign and your landing page converts great in testing, but the conversion tag only fires when the user clicks "Submit" on Chrome. Safari? Nothing. That's 30% of your mobile traffic you're blind to, and you won't know until you check.

I always tell my team: verify on at least three browsers and two devices. Every single time. It takes five minutes and saves you from panicking when reports look wrong later.

Automate the Boring Parts

Manual checks are fine for a quick sanity test. But if you're running campaigns across multiple properties, you need something watching your conversion events around the clock. That's where FunnelLeaks fits in. We built it because we were tired of finding broken conversions two weeks after they broke.

Set up automated ga4 conversion setup verification that pings you the moment an expected event stops firing. Your future self will thank you.

One more thing. If you're using Google Ads conversion imports from GA4, double-check that the link between your Ads account and GA4 property is still active. We've seen it silently disconnect after account-level permission changes, and then your Smart Bidding has no conversion data to work with. You can verify this in Google Ads under Tools > Linked accounts.

Stop Guessing, Start Verifying

Your ad budget is too expensive to waste on broken tracking. Run through your ga4 conversion setup verification this week. Check DebugView, walk the funnel on mobile, and make sure your event parameters match what GA4 expects. If you want continuous monitoring instead of one-off checks, take a look at our plans and see what fits your setup.
