Most GA4 implementations are data graveyards. Hundreds of events firing, custom dimensions everywhere, and nobody can answer the basic question: which marketing efforts actually generate leads?
If you're tracking lead generation, you don't need more data. You need the right data. Here are the 6 GA4 events that actually move the needle.
1. Form Submission (With Quality Signals)
Track every form submission, but go deeper than "form submitted":
- Which form: Contact, quote request, demo signup, newsletter
- Submission status: Success, validation error, abandoned
- Time to complete: Fast submits might be spam; extremely slow might indicate UX friction
Set up a custom event like lead_form_submit with parameters for form_type, page_location, and submission_status. This tells you which pages convert and which forms have issues.
2. Phone Call Clicks
If phone calls matter to your business, track when someone taps your phone number. Use a phone_click event with the page they clicked from.
Better yet, integrate call tracking software (CallRail, CallTrackingMetrics) and push call duration and outcome back to GA4. A 2-minute call tells a different story than a 30-second hangup.
3. Email Link Clicks
When someone clicks a mailto link, that's intent. Track email_click events with the email address domain as a parameter—you'd be surprised how many leads come from certain industries or company sizes.
4. Key Page Views (Not Just Any Page)
Don't track every page view equally. Create events for "high-intent" page views:
- Pricing pages
- Case study pages
- Service detail pages
- About/Team pages (people researching before they buy)
A high_intent_pageview event helps you segment users who are closer to converting.
5. Video Engagement (At Meaningful Thresholds)
Video views are vanity metrics. Track:
- 25% completion: They gave you 30+ seconds
- 50% completion: They're genuinely interested
- 75% completion: High intent—these people are researching
- 100% completion: Consider them a qualified lead
Create video_progress events with percent_viewed as a parameter. This shows you which content actually holds attention.
6. Download Events
Whitepapers, guides, calculators—these are lead magnets. Track file_download events with the resource name and type.
If someone downloads multiple resources, that's a stronger signal than a single download. Use GA4's path analysis to see the journey.
What to Stop Tracking
Here's what's cluttering your reports and adding no value:
- Scroll depth under 90%: Most people don't read to the bottom. 50% and 90% are the only thresholds worth tracking
- Every outbound link: Only track links to partners, competitors, or resources you actually care about
- Generic "click" events: Be specific. A CTA button click is different from a navigation click
- Session start: GA4 tracks this automatically
Making It Actionable
Once these events are firing, build audiences:
- High-intent visitors: Viewed pricing + watched 50%+ of a video
- Engaged leads: Form submitted + returned to site within 7 days
- Researching prospects: 3+ high-intent page views, no conversion yet
Use these audiences for remarketing, sales follow-up prioritization, or content optimization.
Key Takeaways
- Focus on events tied to business outcomes—form submissions, calls, downloads—not generic engagement
- Add context with event parameters—form type, page location, completion status
- Stop tracking vanity metrics—scroll depth and generic clicks clutter your data
- Build audiences from event combinations—high-intent behavior patterns reveal your best leads
