Before you drive a single visitor to your site, you must be able to measure what they do.
### The Essentials:
1. **Google Analytics 4 (GA4)**: Install this immediately. Focus on tracking user journeys, not just pageviews.
2. **PostHog or Mixpanel**: For product-led growth, you need event-tracking to see where users drop off in your onboarding funnel.
3. **Clarity or Hotjar**: Session recording is vital in the early days. Watch how real users interact with your UI to spot confusing UX.
**Action Item:** Create a dashboard tracking your North Star Metric (e.g., 'Weekly Active Users' or 'Signups').
