Core Web Vitals — LCP, INP, CLS — are direct Google ranking factors as of 2024. Passing all three lifts rankings + conversions. Most Miami small business sites fail at least one.
LCP (Largest Contentful Paint): under 2.5s
How fast your hero image/text loads. Fix: WebP images, preload critical resources, kill render-blocking JavaScript. PageSpeed Insights shows you exactly what to fix. Our Miami SEO service includes Core Web Vitals optimization.
INP (Interaction to Next Paint): under 200ms
How fast your site responds to clicks/taps. Replaces FID in 2024. Fix: reduce JavaScript execution, break up long tasks, use web workers for heavy work. WordPress sites with too many plugins fail here.
CLS (Cumulative Layout Shift): under 0.1
How much your page jumps around as it loads. Fix: reserve space for images (width/height attributes), avoid dynamically injected content above-the-fold, use font-display: swap with size adjustments.
Mobile vs desktop scoring
Mobile is harder and matters more (73% of Miami traffic). Aim for green on mobile first — desktop usually follows. Use Chrome DevTools "Lighthouse" tab on mobile mode.
Tools for monitoring
PageSpeed Insights (free). Search Console Core Web Vitals report. Real User Monitoring via Cloudflare or DataDog. Speed regressions silently — monitor weekly.
