Core Web Vitals optimization
Faster UX. Better rankings. Better conversion rate.
Improve LCP, INP, and CLS with a practical roadmap: image and font strategy, critical rendering path fixes, JavaScript reduction, and real-user monitoring.

Core Web Vitals optimization
improves UX and protects conversion rate
Core Web Vitals are not a "score project." They’re a customer experience project: faster perceived load, smoother interactions, fewer layout jumps-measured in real-user signals. We optimize LCP, INP, and CLS with changes that stick.

What we optimize and why it matters
We focus on changes that improve user experience and business outcomes—then validate impact with real-user monitoring and controlled testing.
LCP (Largest Contentful Paint)
Improve time-to-first-meaningful content by fixing image delivery, fonts, critical CSS, and render-blocking resources.
INP (Interaction to Next Paint)
Reduce interaction delay by removing heavy JavaScript, deferring non-critical scripts, and improving event handling.
CLS (Cumulative Layout Shift)
Stop layout jumps by reserving space for media, stabilizing fonts, and fixing late-loaded UI elements.
The real problem: regressions
Many sites "fix" CWV once, then regress. We add governance so new tags, widgets, and scripts don’t re-break performance. (See Third-Party Script Governance.)

Diagnose, prioritize, implement, validate
We don’t optimize by "checklist." We start with constraints (TTFB, rendering path, scripts, images), prioritize by impact, then ship fixes.
Measurement baseline
Know what’s actually happening: we validate tools (RUM, Lighthouse, lab tests) and align on the metrics that matter (mobile first, key templates first). eCommerce audit.
Prioritized roadmap
Impact first: we map fixes to templates (homepage, category, product, cart/checkout, CMS pages) and rank by impact and effort. TTFB / Caching / CDN.
Implementation + QA
Ship fixes safely: changes are implemented and QA’d for rendering and conversion-critical behavior (sticky bars, PDP galleries, tracking). CRO.
Validation + regression prevention
Prevent regressions: we re-test, verify improvements in real-user signals where possible, and set up guardrails (budgets, script approvals, monitoring). Script governance.
Core Web Vitals - Packages
Fix the vitals. Then prevent regressions.
Start with a clear roadmap, implement the high-impact fixes, and add governance so performance doesn’t slip back over time.
