About Page Speed Testing
Website loading speed directly impacts user experience, conversion rates, and search rankings. Our tool analyzes your site's performance and provides actionable recommendations to improve Core Web Vitals and overall speed.
Why Page Speed Matters
Google Ranking Factor
CriticalPage speed is a direct ranking factor in Google's algorithm, especially for mobile searches. Faster sites rank higher in SERPs.
User Experience
Essential53% of mobile users abandon sites that take longer than 3 seconds to load. Every 1-second delay reduces conversions by 7%.
Core Web Vitals
ImportantLCP, FID, and CLS metrics now directly impact search visibility. Our tool measures all three.
Page Speed Optimization Checklist
Technical Optimizations
- Enable compression (Gzip/Brotli)
- Minify CSS, JavaScript, and HTML
- Leverage browser caching
- Remove render-blocking resources
- Use a CDN for static assets
Content Delivery
- Optimize images (WebP format)
- Lazy-load below-the-fold images
- Preload critical resources
- Defer non-critical JavaScript
- Reduce third-party script impact
Common Speed Issues and Solutions
| Issue | Impact | Solution | Priority |
|---|---|---|---|
| Unoptimized images | Increases LCP by 2-5s | Compress, convert to WebP, use srcset | High |
| Render-blocking JS/CSS | Delays First Paint by 1-3s | Defer non-critical resources, inline critical CSS | Critical |
| No browser caching | Repeated resource downloads | Set cache headers (1yr for static assets) | High |
| Excessive DOM size | Slows rendering | Simplify HTML structure | Medium |
| Unminified resources | Larger file transfers | Minify CSS/JS/HTML | Medium |
Core Web Vitals Breakdown
LCP (Largest Contentful Paint)
- Measures loading performance
- Target: ≤2.5s
- Optimize images, preload fonts
- Upgrade hosting if needed
FID (First Input Delay)
- Measures interactivity
- Target: ≤100ms
- Reduce JavaScript execution time
- Use web workers
CLS (Cumulative Layout Shift)
- Measures visual stability
- Target: ≤0.1
- Set image dimensions
- Reserve space for ads/embeds
