Fix Your Slow Website - Measurable Speed Improvements
Every 1 second of load time costs you 7% of conversions. I diagnose what's slowing you down and fix it - with a before/after PageSpeed report.
Who This Is For
This is for anyone whose website feels slow — whether your PageSpeed score is 40 or 75, I can get you measurable improvements that impact both rankings and revenue.
- ✓Businesses with websites scoring below 70 on PageSpeed Insights
- ✓E-commerce stores losing sales due to slow checkout flows
- ✓Blogs and content sites with poor Core Web Vitals scores
- ✓Companies concerned about Google's page experience ranking factor
- ✓Agencies needing performance optimization for client websites
Who This Isn't For
- ✗Websites already scoring 90+ on mobile PageSpeed — you likely need other optimization areas
- ✗Complete website rebuilds — that's a different service (Website Redesign)
- ✗Sites where the hosting server itself is the bottleneck (shared hosting upgrade required)
- ✗One-time quick fixes without a performance budget for ongoing maintenance
Development Process
From idea to deployment. Each phase has clear deliverables so you always know where we stand.
Performance Audit
Day 1-2
I run comprehensive diagnostics across PageSpeed Insights, Lighthouse, and WebPageTest. Every asset — images, scripts, fonts, server response — gets measured. You get a ranked list of what to fix first based on impact.
Optimization Implementation
Day 2-5
I implement all fixes in your actual codebase or CMS — not a staging sandbox. Each change is tested individually to ensure no regressions. Images get automated pipelines, JavaScript is split and deferred, and caching is configured at every layer.
Core Web Vitals Fix
Day 4-7
I specifically target Google's three ranking thresholds: Largest Contentful Paint (2.5s max), Cumulative Layout Shift (0.1 max), and Interaction to Next Paint (200ms max). Each metric is verified on real devices, not just lab conditions.
Verification & Report
Day 7-10
Final report with side-by-side PageSpeed scores, Core Web Vitals comparison, and load time improvements. I also set up ongoing monitoring so you know immediately if performance regresses.
What's Included in Every Project
Every website speed optimization project ships with these core components pre-architected.
Image Optimization Pipeline
Automated WebP/AVIF conversion, responsive srcset generation, lazy loading, and CDN delivery. Images are the #1 cause of slow sites — I make them invisible to load time.
JavaScript Bundle Analysis
Webpack/Rollup bundle analysis, code splitting, tree shaking, and dynamic imports. I identify and remove unused libraries, duplicate code, and render-blocking scripts.
CDN & Caching Strategy
Cloudflare, Vercel Edge, or custom CDN configuration with proper cache headers, stale-while-revalidate, and service worker caching. Static assets are served from the edge closest to your user.
Font Optimization
Font subsetting, WOFF2 compression, preload with font-display swap, and self-hosting Google Fonts. Eliminate the flash of invisible text and render-blocking font requests.
Server & Network Tuning
TTFB optimization, HTTP/2 multiplexing, connection keep-alive, and origin server tuning. If your server takes 1.5s to respond, no frontend optimization will fix it.
Performance Monitoring
Lighthouse CI, Web Vitals library, and RUM (Real User Monitoring) setup. Know when performance regresses before your users complain.
Why Custom Optimization Beats Plugins
WordPress caching plugins and speed optimization plugins give you 80% of the way there — but the last 20% is what separates a 70 from a 95 PageSpeed score. Custom optimization addresses your specific bottlenecks.
Plugins Don't Fix Architecture
A caching plugin won't tree-shake your JavaScript, convert your images to AVIF, or restructure your CSS delivery. It applies generic fixes. Custom optimization targets your exact code and content.
No Bloat Added
Speed plugins add their own JavaScript, CSS, and database overhead. I've seen a 'speed optimization plugin' add 200KB of JS and make the site slower. Custom optimization adds zero overhead.
Permanent, Not Fragile
Plugin-based optimization breaks when you update the plugin, change themes, or add new features. Custom optimizations are baked into your codebase and survive updates.
Measured, Not Guessed
Every change I make is measured before and after. No blind 'optimizations' that might help — or hurt. You see the exact impact of each change.
Custom Optimization vs Plugins
WordPress plugins and generic optimization tools are better than nothing. But for production sites that need to rank and convert, custom optimization goes deeper.
| Custom Development | Plugin-Based Optimization | |
|---|---|---|
| Image optimization | WebP/AVIF with responsive srcset, automated pipeline | Basic compression, no format conversion |
| JavaScript optimization | Tree shaking, code splitting, dynamic imports | Minification only, no bundle analysis |
| Caching strategy | Multi-layer: CDN, browser, service worker, stale-while-revalidate | Single-layer: browser cache headers |
| Font optimization | Subsetting, WOFF2, self-hosted, font-display swap | Google Fonts CDN (extra DNS lookup) |
| Core Web Vitals targeting | LCP, CLS, INP individually diagnosed and fixed | Generic settings, no per-metric targeting |
| Performance monitoring | Lighthouse CI, real user monitoring, alerts on regression | None or basic PageSpeed check |
| Overhead added | Zero — optimizations are in your codebase | Plugin adds its own JS/CSS bloat |
| Survives updates | Yes — baked into architecture | No — breaks on plugin/theme update |
| Before/after measurement | Every change measured individually | No per-change measurement |
| Ongoing maintenance | Manual review every release | Auto-updates (may break optimizations) |
Already tried plugins and not getting the scores you need? Custom optimization addresses what plugins cannot.
Get Your Site AuditedReal-World Experience
I've optimized websites from 40 to 90+ PageSpeed scores, fixed CLS issues on image-heavy sites, reduced JavaScript bundle sizes by 60%, and implemented CDN caching strategies. Every optimization I implement is production-tested and monitored post-deployment.

Tech Stack Rationale
Every technology is chosen for a reason — not just because it is popular.
Next.js Automatic Optimization
Next.js provides image optimization, script loading strategies, and automatic static generation out of the box. For Next.js sites, most optimization is configuring the built-in tools correctly.
Cloudflare CDN
Edge caching, automatic image optimization, brotli compression, and HTTP/2 prioritization. Cloudflare alone can reduce TTFB by 40-60% for global audiences.
WebP + AVIF
WebP reduces image size by 25-35% compared to JPEG. AVIF reduces by 50% more than WebP. Both maintain visual quality. This is the single highest-impact optimization for most sites.
Lighthouse CI
Automated performance testing in CI/CD pipeline. Every deployment is checked for regressions before going live. If a new feature drops the score, you catch it immediately.
Service Workers + Workbox
Precaches critical assets, serves cached pages when offline, and enables stale-while-revalidate strategies. Repeat visits load instantly from the service worker cache.
Common Mistakes to Avoid
I have seen the same patterns stall or kill promising projects. Here is what to avoid — and how I help you sidestep each one.
❌ Optimizing without measuring first
Fix: Never guess what's slow. Always run PageSpeed Insights, Lighthouse, and WebPageTest before making changes. I baseline every metric before touching anything.
❌ Adding a caching plugin and calling it done
Fix: Caching helps repeat visits, not first visits. Most performance issues are first-visit problems: large images, bloated JavaScript, slow server response.
❌ Using too many fonts or font weights
Fix: Each font weight adds 100-200KB. Limit to 2-3 font families with subsetting. Self-host instead of using Google Fonts CDN to eliminate DNS lookups.
❌ Ignoring mobile performance
Fix: Mobile users get 3G-equivalent connections and slower CPUs. If your site is optimized for desktop 5G but slow on mobile 4G, you're optimizing for the wrong audience.
❌ Loading everything on initial page load
Fix: Defer below-the-fold images, non-critical CSS, analytics scripts, chat widgets, and social media embeds. Only load what the user sees immediately.
❌ Not monitoring after optimization
Fix: Performance regresses over time as new features, images, and third-party scripts are added. Set up Lighthouse CI or similar monitoring to catch regressions.
Frequently asked questions
What PageSpeed score can you guarantee?↓
For most websites, I target 85+ on mobile and 95+ on desktop. The final score depends on your content and server setup, but I always provide a before/after report showing measurable improvement.
Does website speed affect Google rankings?↓
Yes, directly. Google uses Core Web Vitals as a ranking factor. A slow website gets penalized in search results and loses conversions from impatient visitors. Fixing speed usually improves both rankings and sales.
Will my website look different after optimization?↓
No. Performance optimization is technical - images load faster, JavaScript is smaller, caching is improved. The visual design remains unchanged.
How long do the improvements last?↓
Permanently, unless you add unoptimized content later. I provide documentation on maintaining performance as your site grows.
