Speed is a Feature, a Conversion Driver, and an SEO Ranking Signal
Google's Core Web Vitals directly correlate with user bounce rates, session duration, and transactional conversion. Every 100ms delay in mobile page load can decrease conversion rates by up to 7%.
Key Performance Optimizations
- Largest Contentful Paint (LCP): Prioritize hero images using fetchpriority="high", preconnect to critical asset domains, and eliminate render-blocking CSS.
- Interaction to Next Paint (INP): Break long JavaScript tasks into smaller micro-tasks using requestIdleCallback and web workers.
- Cumulative Layout Shift (CLS): Reserve exact aspect-ratio dimensions for all images and embeds to prevent unexpected visual jumps during layout rendering.
