7 Critical GA4 Events You Should Be Tracking (You’re Probably Missing #3)
Google Analytics 4 (GA4) is powerful—if you know what to track.
Most people stick with the default events and hope for the best. But here’s the truth: if you’re not customizing your events, you’re leaving money (and insight) on the table.
In this post, we’ll walk you through 7 must-have GA4 events that every website, landing page, or funnel should be tracking. Especially #3—it’s one most marketers overlook but can reveal major drop-off points in your customer journey.
🤖 First, Why Custom Events in GA4 Matter
GA4 is built for flexibility. Unlike Universal Analytics, where you were stuck with rigid categories, GA4 allows you to define your own event parameters—meaning better alignment with your business goals.
Default events like page_view and scroll are a start, but they won’t tell you:
Where your leads are dropping off
What content drives conversions
Which CTAs are ignored
Or what’s holding back your revenue
Let’s fix that 👇
✅ 1. Button Clicks (Especially CTAs)
Tracking call-to-action (CTA) clicks like "Buy Now", "Book Demo", or "Download Guide" is non-negotiable.
Event Name: cta_click Parameter examples: button_text, page_path
💡 Why it matters: It shows which buttons are doing the heavy lifting—and which aren’t.
✅ 2. Form Submissions (Lead Generation Gold)
You need to know when someone completes a form—and what kind.
Event Name: form_submit Parameters: form_id, form_name, page_location
💡 Why it matters: Tracks lead generation performance and helps you A/B test forms.
✅ 3. Video Engagement (The Most Missed Event)
If you're using video in your funnel—landing pages, product explainers, testimonials—you need to track if people are actually watching.
Event Name: video_progress Track when users:
Start video
Reach 25%, 50%, 75%, 100%
💡 Why it matters: You’ll discover if your videos are doing their job—or wasting scroll space.
✅ 4. Scroll Depth (See Where Attention Drops)
GA4 includes a basic scroll event (90% scroll), but you can customize depth triggers for 25%, 50%, 75%, and 100%.
Event Name: scroll_depth Parameters: percentage_scrolled, page_path
💡 Why it matters: Reveals which content holds attention—and what causes bounce.
✅ 5. Outbound Link Clicks (What Sends Users Away)
If users are clicking links to third-party sites, affiliates, or social media—you should know.
Event Name: outbound_click Parameters: destination_url
💡 Why it matters: Helps you understand what’s distracting or converting your traffic.
✅ 6. Product Views and Add to Cart (Ecommerce)
For ecommerce brands, this is a no-brainer. Track every step of the funnel.
Events:
view_item
add_to_cart
begin_checkout
purchase
💡 Why it matters: Allows you to pinpoint exactly where revenue is leaking.
✅ 7. Error Messages or Failed Submissions
Do people run into broken forms? Do buttons fail silently?
Event Name: form_error or js_error Parameters: error_message, page_path, device_type
💡 Why it matters: You can’t fix what you don’t know is broken—and these events reveal the invisible UX blockers.
🔍 Bonus Tip: Use GTM (Google Tag Manager)
Set up these events using Google Tag Manager for cleaner management and more flexible customization. You’ll be able to fine-tune exactly how and when events fire—without messing with site code.
📈 The Real Win? Insight that Drives Action
Tracking these 7 events will give you more than just data—they give you diagnostics:
Which content converts
Which CTAs flop
Where buyers disappear
What kills trust
And how to fix it
And that’s the difference between just measuring traffic… and increasing revenue.
