# PageSpeed Verification Report
|
||||
|
||||
**Date:** 2025-01-25
|
||||
**Subtask:** 2-4 - Verify PageSpeed scores meet >90% threshold
|
||||
**Site:** https://www.damjan-savic.com/

|
||||
|
||||
## Executive Summary
|
||||
|
||||
This report documents the PageSpeed verification for the Damjan Savić portfolio website. Due to network proxy restrictions blocking the PageSpeed Insights API, verification was conducted using:
|
||||
1. Local Playwright-Lighthouse audits against dev server
|
||||
2. Manual verification instructions for production site
|
||||
|
||||
---
|
||||
|
||||
## Local Development Environment Results
|
||||
|
||||
Tests run against `http://localhost:3000` using Playwright-Lighthouse.
|
||||
|
||||
### Homepage Performance by Locale
|
||||
|
||||
| Locale | Performance | Accessibility | Best Practices | SEO |
|
||||
|--------|-------------|---------------|----------------|-----|

|
||||
| SR | 57%* | 94% | 100% | 83%*|
|
||||
|
||||
*Note: Performance and SEO scores in dev mode are expected to be lower due to:
|
||||
- No minification
|
||||
- No code splitting optimization
|
||||
- No cache headers
|
||||
- Source maps included
|
||||
- Hot Module Replacement (HMR) overhead
|
||||
|
||||

||||
## Production Verification Instructions
|
||||
|
||||
Since the PageSpeed Insights API is blocked by network proxy, verify production scores manually:
|
||||
|
||||
### Method 1: PageSpeed Insights Web Interface
|
||||
|
||||
1. Visit: https://pagespeed.web.dev/
|
||||
2. Enter URL: `https://www.damjan-savic.com/`
|
||||
3. Click "Analyze"
|
||||
4. Record scores for Desktop and Mobile
|
||||
|
||||
### Method 2: Chrome DevTools Lighthouse
|
||||
|
||||
1. Open Chrome and navigate to https://www.damjan-savic.com/
|
||||
2. Open DevTools (F12)
|
||||
3. Go to "Lighthouse" tab
|
||||
4. Select: Performance, Accessibility, Best Practices, SEO
|
||||
5. Choose "Mobile" or "Desktop"
|
||||
6. Click "Generate report"
|
||||
|
||||

## Expected Production Scores
|
||||
|
||||
Based on the optimizations already in place, production scores are expected to be significantly higher:
|
||||
|
||||
### Current Optimizations (Verified in Codebase)
|
||||
|
||||
1. **Image Optimization**
|
||||
- AVIF and WebP formats configured
|
||||
- Multiple device sizes (640-2048px)
|
||||
- Lazy loading for below-fold images
|
||||
- Priority loading for hero images
|
||||
|
||||
2. **Font Optimization**
|
||||
- Font display: swap (prevents FOIT)
|
||||
- Font preloading configured
|
||||
|
||||
3. **Resource Hints**
|
||||
- Preconnect to fonts.googleapis.com
|
||||
- Preconnect to fonts.gstatic.com
|
||||
- DNS-prefetch to Supabase
|
||||
|
||||
4. **Caching**
|
||||
- Static assets: 1 year cache (immutable)
|
||||
- Next.js static files: Long-term caching
|
||||
|
||||
5. **Code Optimization**
|
||||
- Package import optimization (lucide-react, framer-motion, etc.)
|
||||
- Console removal in production
|
||||
- Static generation for all pages
|
||||
|
||||
6. **Security Headers**
|
||||
- HSTS with preload
|
||||
- Content-Security-Policy ready
|
||||
- X-Frame-Options
|
||||
- X-Content-Type-Options
|
||||
|
||||
### Expected Production Scores
|
||||
|
||||
| Category | Expected Desktop | Expected Mobile |
|
||||
|----------------|------------------|-----------------|
|
||||
| Performance | 85-95% | 75-90% |
|
||||
| Accessibility | 90-100% | 90-100% |
|
||||
| Best Practices | 95-100% | 95-100% |
|
||||
| SEO | 90-100% | 90-100% |
|
||||
|
||||
---
|
||||
|
||||
## Recommendations for Score Improvement
|
||||
|
||||
If production scores don't meet the 90% threshold:
|
||||
|
||||
### Performance
|
||||
|
||||
1. **Optimize hero-portrait.jpg** (identified as 2.9MB - needs compression)
|
||||
2. **Implement critical CSS inlining**
|
||||
3. **Add loading="eager" to LCP image**
|
||||
4. **Review third-party script loading** (defer GA)
|
||||
|
||||
### SEO
|
||||
|
||||
1. **Add canonical URLs** to all pages
|
||||
2. **Ensure hreflang tags** are properly configured
|
||||
3. **Add breadcrumb structured data**
|
||||
4. **Verify meta descriptions** length (150-160 chars)
|
||||

## Test Infrastructure
|
||||
|
||||
The following test files are available for ongoing verification:
|
||||
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `tests/e2e/performance.spec.ts` | Playwright-Lighthouse performance audits |
|
||||
| `scripts/pagespeed-check.js` | PageSpeed API verification (requires network access) |
|
||||
| `PERFORMANCE_BASELINE.md` | Initial performance baseline documentation |
|
||||
|
||||
### Running Tests
|
||||
|
||||
```bash
|
||||
# Run all performance tests (requires dev server)
|
||||
npx playwright test tests/e2e/performance.spec.ts --project=chromium --workers=1
|
||||
|
||||
# Run Core Web Vitals tests only
|
||||
npx playwright test tests/e2e/performance.spec.ts --grep="Core Web Vitals" --project=chromium
|
||||
|
||||
# Run Resource Loading tests only
|
||||
npx playwright test tests/e2e/performance.spec.ts --grep="Resource Loading" --project=chromium
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Conclusion
|
||||
|
||||
**Local Development Status:**
|
||||
- ✅ Accessibility: PASSES (92-100%)
|
||||
- ✅ Best Practices: PASSES (100%)
|
||||
- ⚠️ Performance: Expected low in dev mode (47-69%)
|
||||
- ⚠️ SEO: Expected low in dev mode (75-83%)
|
||||
|
||||
**Production Verification Required:**
|
||||
Manual verification via PageSpeed Insights web interface is required due to API access restrictions.
|
||||
|
||||
**Recommendation:**
|
||||
Verify production site scores meet the 90% threshold using https://pagespeed.web.dev/ before marking this subtask as complete.
