Performance Optimization

Website Page Speed
Optimization

Slow websites lose visitors, conversions, and search rankings. I specialize in improving Core Web Vitals — the metrics Google uses to measure page experience — to ensure your site loads fast, responds instantly, and ranks higher.

TL;DR: Byron Johnson provides deep-level Core Web Vitals optimization (LCP, INP, CLS) for React and Next.js sites. This is hands-on code-level engineering — not plugin installation. Results: higher Google PageSpeed scores, better search rankings, faster load times, and measurably improved conversion rates. Available at $60/hr with a full audit and upfront quote.

Mastering Core Web Vitals

Google's Core Web Vitals are critical ranking signals. I target these specific metrics to ensure your site passes with flying colors and outperforms competitors in search results.

LCPtarget: < 2.5s

Largest Contentful Paint

Optimizing heavy assets, server response times, and render-blocking resources to ensure main content loads fast.

INPtarget: < 200ms

Interaction to Next Paint

Reducing JavaScript execution time and optimizing event handlers for immediate, snappy responsiveness.

CLStarget: < 0.1

Cumulative Layout Shift

Reserving space for dynamic content, optimizing font loading, and stabilizing layout elements to eliminate visual jumps.

My Optimization Toolkit

I use a comprehensive set of proven techniques to shave off milliseconds from every request. This is deep-level code optimization, not just installing a plugin — it's the kind of work that requires 15+ years of hands-on experience.

Common Page Speed Questions

Why does website page speed matter for Google rankings?

Google uses Core Web Vitals (LCP, INP, and CLS) as direct ranking signals in its Page Experience algorithm. Sites with poor Core Web Vitals scores rank lower than competitors with equivalent content. A one-second improvement in LCP is associated with 8-12% higher conversion rates on average. Page speed is not optional — it directly impacts both visibility and revenue.

What is the difference between LCP, INP, and CLS?

LCP (Largest Contentful Paint) measures how fast the main content loads — target is under 2.5 seconds. INP (Interaction to Next Paint) measures how quickly a page responds to user actions — target is under 200ms. CLS (Cumulative Layout Shift) measures visual stability (how much the layout shifts while loading) — target is a score below 0.1. All three must pass for a "Good" Core Web Vitals assessment.

How does Byron improve Core Web Vitals for React and Next.js sites?

Byron uses code-level techniques including Next.js Image component optimization (AVIF/WebP with priority loading), next/font for zero-CLS font loading, React.lazy and dynamic imports for code splitting, script deferment via Next.js Script component, bundle analysis to eliminate large unnecessary dependencies, and Intersection Observer for lazy loading off-screen content. Every change is measured before and after with Lighthouse and Chrome DevTools.

How much does page speed optimization cost?

Byron charges $60/hr for page speed optimization work. Most React/Next.js sites can be meaningfully improved in 4-8 hours, making the total cost $240-$480 for a significant performance improvement.
