How do I make my website faster?

Start with the biggest wins: optimize images (compress, use modern formats like WebP, specify dimensions), enable caching, and use a CDN. Minimize JavaScript—every kilobyte affects load time. Choose fast hosting. For detailed diagnosis, run Google PageSpeed Insights or Lighthouse in Chrome DevTools. Fix issues in order of impact, focusing on Core Web Vitals: LCP (loading), INP (interactivity), and CLS (visual stability).
