Performance auditing with Lighthouse verifies Core Web Vitals and readiness by running audits against your production URL, measuring LCP, FID, and CLS metrics, then comparing results against targets (LCP < 2.5s, FID < 100ms, CLS < 0.1) and >90 scores across Performance, Accessibility, Best Practices, and SEO categories.

Core Web Vitals are three key performance metrics: LCP (Largest Contentful Paint) measures loading speed, FID (First Input Delay) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. Meeting these targets ensures users experience fast, responsive, stable pages and improves search ranking visibility.

Yes, Lighthouse audits measure performance separately for mobile and desktop environments, capturing distinct metrics for each context. This ensures your site meets Core Web Vitals targets across all user device types before release.

After auditing, review the actionable checklist of common issues, prioritizing remediation: optimize images, defer non-critical JavaScript, improve font delivery, and resolve layout shifts. Re-audit after each fix to verify improvement against LCP, FID, CLS targets and >90 category scores.

Yes, Lighthouse audits work across both static sites and web applications. It measures the same Core Web Vitals metrics and performance scores regardless of site type, making it suitable for release verification across different project architectures.
