What are Core Web Vitals?

Core Web Vitals are Google's metrics for user experience: LCP (Largest Contentful Paint) for loading, FID (First Input Delay) for interactivity, and CLS (Cumulative Layout Shift) for visual stability. These directly impact SEO rankings, and we optimize specifically for passing scores.

Will optimization break my site?

We implement changes carefully with thorough testing at each step. All optimizations are tested in staging before production. We maintain rollback capability and monitor closely after deployment. Our process is designed to improve speed without breaking functionality.

How long do optimizations last?

The core optimizations are permanent, but performance requires ongoing attention. New features, content, and third-party scripts can impact speed over time. We can set up monitoring to alert you to regressions and offer maintenance plans to keep performance optimal.

Do you optimize mobile performance?

Absolutely. Mobile performance is critical as most users are on mobile devices. We optimize for mobile-first, ensuring fast load times on slower connections, proper image sizing for mobile screens, and touch-friendly interactions.
