At KoreDesk we build every project with Lighthouse 95+ in performance and SEO. It's not magic — it's a systematic process any team can follow.
What Lighthouse measures
Lighthouse evaluates 5 dimensions (0-100 each): Performance, Accessibility, Best Practices, SEO, and PWA.
The 7 key optimizations for 95+
1. Optimized images
Use WebP/AVIF formats with lazy loading. Set explicit dimensions to avoid CLS.
2. Optimized fonts
Use font-display: swap. Subset fonts. Prefer WOFF2 format.
3. Efficient JavaScript
Eliminate unused JS. Code-split. Defer non-critical scripts.
4. Optimized CSS
Eliminate unused CSS. Inline critical CSS.
5. SSR and Static Generation
Generate static pages when possible (SSG).
6. Structured data
Correct schema.org helps your Lighthouse SEO score.
7. Core Web Vitals
LCP < 2.5s, INP < 200ms, CLS < 0.1.
The Next.js advantage for Lighthouse
Next.js provides automatic optimizations for images, fonts, code-splitting and static generation.
