SEO & Performance

This guide explains how to optimize the Open Hardware Initiative website for search engines and fast loading.

SEO (Search Engine Optimization)

Meta Tags

The website includes essential meta tags in index.html:

<title>Open Hardware Initiative - TUM</title>
<meta name="description" content="Student-led group at TUM focused on hardware acceleration, chip design, and smart manufacturing systems.">
<meta name="keywords" content="hardware, FPGA, chip design, TUM, student group">
<meta name="author" content="Open Hardware Initiative">
<meta name="robots" content="index, follow">

Open Graph Tags

Social media sharing optimization:

<meta property="og:title" content="Open Hardware Initiative">
<meta property="og:description" content="Hardware acceleration and chip design at TUM">
<meta property="og:image" content="/media/logos/ohw-logo.png">
<meta property="og:url" content="https://open-hardware-initiative.com">

Semantic HTML

  • Proper heading hierarchy (h1, h2, h3, etc.)

Performance Optimization

Build Optimizations

  • Vite bundling - Fast builds with tree shaking
  • Code splitting - Automatic chunk splitting
  • Asset compression - Gzip compression for all assets
  • Minification - CSS and JavaScript minified

Image Optimization

  • WebP format - Modern, efficient image format
  • Responsive images - Different sizes for different screens
  • Lazy loading - Images load as needed
  • Optimized file sizes - Compressed before deployment

Loading Performance

  • Caching headers - Static assets cached aggressively

Core Web Vitals

Largest Contentful Paint (LCP)

Target: < 2.5 seconds

  • Optimize hero images
  • Use efficient image formats
  • Minimize render-blocking resources

First Input Delay (FID)

Target: < 100 milliseconds

  • Minimize JavaScript execution
  • Use code splitting
  • Optimize bundle size

Cumulative Layout Shift (CLS)

Target: < 0.1

  • Set image dimensions
  • Reserve space for dynamic content
  • Avoid layout shifts during loading

Performance Monitoring

Tools to Use

  • Google PageSpeed Insights - Overall performance score
  • Lighthouse - Detailed performance audit
  • WebPageTest - Real-world performance testing
  • Chrome DevTools - Performance profiling

Key Metrics to Track

  • Page load time - Total time to load
  • Time to First Byte (TTFB) - Server response time
  • Bundle size - JavaScript and CSS size
  • Image sizes - Total image payload

SEO Best Practices

Content Structure

  • Clear page titles - Descriptive and keyword-rich
  • Meta descriptions - Compelling summaries (150-160 characters)
  • Heading structure - Logical hierarchy (H1 → H2 → H3)
  • Internal linking - Connect related pages

Technical SEO

  • Fast loading - Optimize for speed
  • HTTPS - Secure connection
  • Clean URLs - Descriptive, readable URLs

Local SEO

  • TUM location - Mention university affiliation
  • Contact information - Clear contact details

Performance Checklist

Before Deployment

  • Images optimized - Compressed and proper format
  • Bundle size checked - Under 500KB total
  • Meta tags complete - Title, description, Open Graph
  • Alt text added - All images have descriptions
  • Mobile tested - Responsive on all devices

After Deployment

  • PageSpeed score - Above 90
  • Core Web Vitals - All metrics in green
  • Search console - No errors reported
  • Social sharing - Open Graph tags working
  • Analytics tracking - Google Analytics installed

Common Issues

Performance Problems
