Website Speed Optimization
Speed up your website and improve Core Web Vitals. Loading speed analysis and optimization for better Google rankings and higher conversions.
Speed optimization
Website speed directly impacts conversions, user satisfaction, and search engine rankings. Every extra second of loading time increases the chance that a visitor will leave. I optimize websites to load as fast as possible on all devices.
Why speed matters
- 53% of users abandon a page that takes longer than 3 seconds to load
- Google uses Core Web Vitals as a ranking factor
- A faster website means higher conversion rates and lower bounce rates
- Improving
LCPby 1 second can increase conversions by 27%
What I optimize
Images and media
Images are the most common cause of slow loading. I ensure proper formats (WebP, AVIF), responsive sizes, lazy loading, and compression without visible quality loss.
Code and assets
CSS and JavaScript minification and bundling, removal of unused code (tree-shaking), proper resource loading order, and elimination of render-blocking resources.
Caching and CDN
Proper browser caching strategy setup, CDN implementation or optimization, transfer compression (Brotli, Gzip), and HTTP header optimization.
Rendering and interactivity
Core Web Vitals optimization (LCP, INP, CLS), minimizing layout shifts, proper font loading without flashing, and critical rendering path optimization.
Server side
Server response time optimization (TTFB), server-side caching, database query optimization, and proper HTTP/2 or HTTP/3 configuration. Choosing the right architecture (SSR, SSG) plays a key role.
How I measure performance
Tools and metrics
I use a combination of tools for a complete picture of website performance:
- Lighthouse for comprehensive performance scoring
- PageSpeed Insights for real user data (CrUX)
- WebPageTest for detailed loading waterfall analysis
- Chrome DevTools for profiling and debugging
Core Web Vitals(LCP,INP,CLS,TTFB) as the primary user performance indicators
Optimization process
Measurement and analysis
I measure the current state using Lighthouse, PageSpeed Insights, and WebPageTest. I identify the biggest performance bottlenecks and determine which Core Web Vitals metrics need improvement.
Optimization plan
I compile a list of improvements sorted by impact and complexity. I focus first on changes that bring the biggest improvement with the least effort. Each item has a clear expected impact on a specific metric.
Implementation
I carry out optimizations while continuously measuring improvements. From image compression and caching setup to code refactoring and server optimization. Emphasis on ensuring changes don't break functionality.
Verification and documentation
I compare before and after results, document all changes made. I prepare recommendations for maintaining performance going forward and set up monitoring.
