Before you trust your GA4 data for business decisions, verify it is actually accurate. Work through this checklist to catch tracking problems before they cost you.
Real Time Verification
- Open the Realtime report and browse your own site in another tab
- Confirm your test visit shows up within a minute or two
- Click through key pages and confirm each page view is recorded
- Trigger a key event, like a form submission, and confirm it appears
Cross Checking Your Numbers
- Compare GA4 lead counts against your CRM for the same date range
- Compare GA4 purchase counts against your order system, if applicable
- Check that traffic source data lines up with what you expect from your campaigns
- Watch for sudden unexplained spikes or drops in traffic
Common Errors To Check For
- Duplicate tags firing the same event twice
- Missing tracking on new pages added after the initial setup
- Internal team traffic inflating your session counts
- Broken tags after a website redesign or platform migration
Frequently Asked Questions
How often should I verify my GA4 tracking?
Check it any time you launch a new page, change your website platform, or notice numbers that look off. A quick monthly check is a good habit even if nothing has changed.
What if my numbers do not match my CRM?
Some difference is normal since GA4 and a CRM measure things differently. But a large, consistent gap usually means a tracking problem worth investigating.
