Analytics without action is just numbers. But action without analytics is just guessing. The best digital products are built by teams who measure obsessively, learn continuously, and iterate relentlessly.
Core Web Vitals: The Foundation
Google's Core Web Vitals are the baseline for performance measurement. Three metrics: Largest Contentful Paint (LCP) — loading performance, should be under 2.5s. First Input Delay (FID) — interactivity, under 100ms. Cumulative Layout Shift (CLS) — visual stability, under 0.1.
Google Analytics 4: What to Track
Traffic Sources
Where are your users coming from? Organic search, paid ads, social, direct, referral. Understanding your traffic sources tells you where to invest.
User Behavior
What pages do users visit? In what order? Where do they drop off? Behavior flow reveals where your funnel leaks.
Conversion Events
Define what "success" looks like on your site. Form submissions, purchases, email sign-ups, document downloads. Track these as events in GA4.
Heatmaps and Session Recordings
Tools like Hotjar or Microsoft Clarity show you exactly where users click, scroll, and hesitate. Session recordings reveal user frustration in ways that numbers cannot.
Data tells you what is happening. Recordings tell you why.
Search Console: Your SEO Dashboard
Google Search Console shows you which queries bring users to your site, your average position, and click-through rates. It also alerts you to technical issues like indexing errors.
