Website Speed & Core Web Vitals Optimization Services

Deep engineering optimizations to slash page load times, achieve green Core Web Vitals, and maximize conversion rates.

Service Overview

Every millisecond of page load latency directly impacts your conversion rates and search rankings. Studies show that a 1-second delay can reduce conversions by up to 7% and cause over 50% of mobile users to abandon your site. I perform deep, code-level performance tuning across your frontend bundles, media assets, caching configurations, and server responses to ensure your website loads in under one second across all global locations.

Who This Service Is For

E-commerce stores, SaaS platforms, and high-traffic websites experiencing high bounce rates, poor mobile performance, or failing Google Core Web Vitals assessments.

Key Benefits & Deliverables

  • Near-instant page load times with Largest Contentful Paint (LCP) under 1.2 seconds.
  • Perfect Core Web Vitals compliance (LCP under 2.5s, INP under 200ms, CLS under 0.05).
  • Significant reduction in JavaScript bundle sizes through dynamic imports and tree-shaking.
  • Modern next-gen image compression (WebP and AVIF) with responsive srcset attributes.
  • Optimized browser caching, HTTP/2 multiplexing, and Edge CDN distribution.

Development Process & Workflow

01

Performance Profiling & Bottleneck Analysis

Benchmarking Waterfall metrics, CPU execution profiles, and render-blocking resources.

02

Asset Compression & Bundle Optimization

Converting assets to AVIF/WebP, splitting JS bundles, and purging unused CSS.

03

Critical Rendering Path Optimization

Inlining critical CSS, deferring non-critical scripts, and preloading critical web fonts.

04

Caching & Edge CDN Configuration

Configuring immutable cache headers, brotli compression, and distributed CDN delivery.

Technology Stack & Tooling

  • Google Lighthouse
  • Web Vitals API
  • Sharp
  • Brotli Compression
  • Cloudflare CDN
  • ESBuild
  • Rollup

Why Work With Me

I approach performance from an engineering perspective. I don't just install caching plugins—I analyze network waterfalls, optimize DOM complexity, rewrite inefficient loops, and configure Edge routing.

Typical Outcomes:

  • 95+ Lighthouse Performance scores across both mobile and desktop audits.
  • Passing status on all Google Core Web Vitals field data metrics.
  • Lower visitor bounce rates and higher conversion rates across marketing campaigns.

Frequently Asked Questions

Why is website speed so critical for conversion rates?

Speed is the foundation of user experience. Fast websites keep visitors engaged, reduce checkout abandonment, and send strong positive quality signals to Google's ranking algorithms.

Can you optimize speed on WordPress websites?

Yes! WordPress often suffers from heavy plugin scripts and unoptimized databases. I optimize database queries, strip unused CSS/JS assets, implement object caching, and configure image optimization.

Will speeding up my site alter its visual design or features?

No, the visual design and interactive features remain identical. All optimizations happen under the hood to how files, fonts, and scripts are delivered and rendered by the browser.

What metrics are measured in Google Core Web Vitals?

Core Web Vitals measure real-world user experience across three areas: Largest Contentful Paint (loading speed), Interaction to Next Paint (responsiveness), and Cumulative Layout Shift (visual stability).
