Jinsi ya Kufahamu Web Vitals na Performance Metrics

Web Vitals ni metrics muhimu zinazotathmini performance na user experience ya website yako. Google inatumia metrics hizi kama sehemu ya SEO ranking. Metrics kuu ni Core Web Vitals:

Largest Contentful Paint (LCP): Muda wa kupakia largest visible content (inapaswa < 2.5s).

First Input Delay (FID): Muda wa first interaction (inapaswa < 100ms).

Cumulative Layout Shift (CLS): Inapima stability ya layout (inapaswa < 0.1).

Jinsi ya Kupima Metrics:

1. Kutumia Google Lighthouse

Fungua DevTools (F12) → Lighthouse → Generate report.

2. Kutumia Web Vitals JavaScript Library
<script src="https://unpkg.com/web-vitals@2.1.2/dist/web-vitals.umd.js&quot;&gt;&lt;/script&gt;
<script>
webVitals.getCLS(console.log);
webVitals.getFID(console.log);
webVitals.getLCP(console.log);
</script>

3. Kutumia Chrome UX Report na PageSpeed Insights

PageSpeed Insights
inatoa metrics na recommendations.

Tips:

Optimize images na media files ili kupunguza LCP.

Minimize JavaScript blocking execution ili kupunguza FID.

Tumia size-fixed elements ili kudhibiti CLS.

Angalia metrics mara kwa mara baada ya updates za website.
