Core Web Vitals Optimization
Faster interactions. Better rankings.
We fix INP, LCP, and CLS with image/CDN strategy, JS right-sizing, and layout hardening—validated in field data.
Why Core Web Vitals move SEO and conversion
LCP – Largest content paint
Optimize hero media, preconnect/preload, choose the right image formats, and serve from the right edge.
CLS – Layout stability
Reserve space for media, avoid late inserted UI, and tame third-party injections that cause jumps.
Audit → Fix → Validate → Monitor
1) Performance audit
Critical path, render budget, long tasks, third-party cost, images, fonts, and route-level analysis.
2) Image/CDN strategy
Next-gen formats, responsive sets, lazy-loading, priority hints, and smart CDN rules.
3) JS right-sizing
Code splitting, island/partial hydration, tree-shaking, and removing dead/duplicate libs.
4) Layout hardening
Aspect ratios, reserved slots, font fallback strategy, and avoiding late UI injections.
5) Third-party governance
Defer/async, consent-aware loading, and periodic reviews of tag costs and SLAs.
6) Validate & monitor
Lab checks and field verification; dashboards on INP/LCP/CLS and regressions alerts.
Stacks we optimize
React/Next & Astro
Route-level splitting, selective hydration, RSC/SSR choices, and asset budgets.
Headless CMS & Ecommerce
Critical path for PDP/PLP, image strategy, cache keys, and search facets.
WordPress/Laravel
Cache layers, image plugins done right, script governance, and template cleanup.

FAQs
Do fonts hurt CLS?
They can. We set font-display, preload critical fonts, and tune fallback metrics to avoid jumps.
Is lazy loading bad for LCP?
Lazy load non-critical media only. Hero elements get priority hints/preload to improve LCP.
What about third-party scripts?
We audit cost, defer/async where safe, and cut unused tags. Consent-aware loading keeps compliance intact.
Do you provide dashboards?
Yes—clear views of INP/LCP/CLS, changes over time, and guardrails to catch regressions early.
Faster site, happier users, stronger SEO
