Hire a Core WebVitals Expert.Lighthouse 99+.

Core Web Vitals are Google's three user-experience metrics: LCP (Largest Contentful Paint) measures loading performance, INP (Interaction to Next Paint) measures responsiveness, and CLS (Cumulative Layout Shift) measures visual stability. They directly influence Google Search rankings through the Page Experience signal — sites in the "Good" range consistently rank higher for competitive keywords.

Most projects see meaningful improvement within 2–4 weeks. Quick wins like image optimisation, render-blocking resource removal, and font loading fixes often deliver 30–50% LCP improvement in the first sprint. CLS fixes are typically faster. INP improvements depend on JavaScript complexity but are usually resolved within 4–6 weeks.

For most modern React/Next.js applications, a Lighthouse Performance score of 90–99 is achievable. Content-heavy or highly dynamic pages typically land in the 85–95 range. Our engineers have delivered 99+ scores on client projects including e-commerce platforms, SaaS dashboards, and marketing sites.

Yes — Google confirmed Core Web Vitals as a ranking factor in 2021. Moving from "Poor" to "Good" on CWV can improve your position for competitive queries, particularly where page experience is a tiebreaker. Beyond rankings, faster pages reduce bounce rate and increase conversion rate — a 1-second LCP improvement typically lifts conversions by 3–7%.
