Overall Assessment: Performance is good but limited by large GIF assets (~9.6 MB). SEO is now excellent with proper meta tags, canonical URL, and single H1. Accessibility is excellent with all ARIA labels and skip-to-content link. Best practices include comprehensive security headers (CSP, X-Frame-Options).

✅ Completed Optimizations (January 20, 2026)

1. SEO Improvements

Added canonical URL (web/index.html): <link rel="canonical" href="https://www.vanessadepraute.dev/" />
Fixed robots meta tag: Changed from noindex to index, follow, max-image-preview:large
Fixed Open Graph image path: Changed from /avatar.png (relative) to https://www.vanessadepraute.dev/assets/profilepicture.webp (absolute URL)
Fixed heading hierarchy: Changed FAQ accordion headings from <h1> to <h3> (reduced from 11 H1 to 1 H1 on main page)

2. Accessibility Improvements

Added skip-to-content link: <a href="#main-content" class="skip-link">Skip to main content</a> with CSS styling
Added ARIA label to ContactButton: Added aria-label={t("footer.contact")}
Verified existing ARIA labels: AnimatedThemeToggler, AnimatedSoundToggler, and LanguageSwitcher have proper labels
Verified Footer links: All social media links have appropriate aria-label attributes

3. Security Headers (Best Practices)

Added to vercel.json:

Content-Security-Policy:
- default-src 'self'
- script-src 'self' 'unsafe-inline' 'unsafe-eval' https://www.vanessadepraute.dev
- style-src 'self' 'unsafe-inline' https://fonts.googleapis.com
- img-src 'self' 'unsafe-inline' data: https://www.vanessadepraute.dev
- font-src 'self' https://fonts.gstatic.com https://fonts.googleapis.com
- connect-src 'self' https://www.vanessadepraute.dev https://o4509101039419392.ingest.de.sentry.io https://sentry.io
- frame-src 'self'
- object-src 'none'
X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Referrer-Policy: strict-origin-when-cross-origin

4. Performance Optimizations

Added resource preloading in index.html:
- JetBrains Mono font (.woff2) for faster text rendering
- Profile picture (/assets/profilepicture.webp) for faster LCP

5. Code Quality

Build verification: Successfully ran pnpm build with no errors
All TypeScript compilation passed
Project is production-ready

⚠️ Pending Optimizations (High Impact)

1. GIF Image Optimization

Current situation:

web/public/gifs/ contains 7 GIF files totaling ~9.6 MB:
- cat-play.gif: 5.0 MB (main issue)
- cat-curious.gif: 1.7 MB
- cat-cool.gif: 2.1 MB
- cat-dance.gif: 98 KB
- cat-happy.gif: 558 KB
- cat-jump.gif: 37 KB
- cat-success.gif: 51 KB
- cat-celebrate.gif: 62 KB

Recommendation:

Convert GIFs to modern formats (WebP/AVIF) which can reduce file size by 60-80%
Consider lazy loading GIFs (they're not visible on initial page load)
Use animated WebP or videos (MP4/WebM) for better compression

Expected improvement:

Total transfer size: 9.6 MB → ~2.4 MB (75% reduction)
LCP improvement: Faster initial page load
Better Core Web Vitals scores
Overall Performance score: 65 → ~85

Tools for conversion:

ffmpeg for video-to-WebP conversion
cwebp for GIF-to-WebP conversion
Squoosh (https://squoosh.app/) for WebP optimization

Example commands:

# Convert GIF to WebP
ffmpeg -i cat-play.gif -vf "fps=10,scale=320:-1:flags=lanczos" -c:v libwebp -q 50 -loop 0 cat-play.webp

# Convert to AVIF (modern format, better compression)
ffmpeg -i cat-play.gif -vf "fps=10,scale=320:-1:flags=lanczos" -c:v libaom-av1 -crf 30 -pix_fmt yuv420p cat-play.avif

2. Implement Lazy Loading for GIFs

Add loading="lazy" attribute to GIF images that appear below the fold to improve initial page load.

Example:

<img
  src="/gifs/cat-play.gif"
  alt="Cat playing animation"
  loading="lazy"
  className="..."
/>

📊 Expected Score Improvements

After implementing GIF optimization:

Category	Before	After	Improvement
Performance	65/100	~85/100	+20 points
SEO	100/100	100/100	Maintained
Accessibility	100/100	100/100	Maintained
Best Practices	92/100	~95/100	+3 points
Overall	~67/100	~90/100	+23 points

📝 Modified Files

web/index.html: SEO meta tags, canonical URL, skip link, preload directives
web/src/index.css: Skip-link styles
web/src/components/ui/accordion-05.tsx: Changed H1 to H3
web/src/components/ContactButton.tsx: Added ARIA label
vercel.json: Added security headers (CSP, X-Frame-Options, etc.)

🚀 Next Steps

High Priority: Convert all 7 GIFs to WebP/AVIF formats
Medium Priority: Implement lazy loading for GIFs
Low Priority: Review inline styles (219 elements) from frameworks
Optional: Implement service worker for offline support
Optional: Add more detailed structured data (Organization, BreadcrumbList, etc.)
