Introduction​

Performance is crucial for user experience and SEO. In this guide, we'll explore various techniques to optimize your Hugo site for maximum performance.

Asset Optimization​

Image Optimization​

Images often contribute the most to page weight. Here's how to optimize them:

layouts/shortcodes/optimized-image.html
{{ $image := .Page.Resources.GetMatch (printf "%s" (.Get "src")) }}
{{ $options := dict "targetWidth" 800 "quality" 85 }}
{{ $processed := $image.Process "resize 800x webp q85" }}
<img src="{{ $processed.RelPermalink }}" 
     alt="{{ .Get "alt" }}"
     loading="lazy"
     className="rounded-lg shadow-lg">

CSS and JavaScript​

Minimize your asset footprint:

  • Minify CSS and JavaScript
  • Bundle assets appropriately
  • Remove unused code

Caching Strategies​

  1. Browser Caching

    • Set appropriate cache headers
    • Use versioned assets
    • Implement service workers

  2. Hugo Caching

    • Use .Scratch for expensive operations
    • Cache partial results
    • Implement memoization

Content Delivery​

CDN Setup​

config.toml
[params.cdn]
  enable = true
  provider = "cloudfront"
  domain = "cdn.example.com"

Edge Computing​

Leverage edge computing for faster content delivery:

  • Deploy to multiple regions
  • Use edge functions when needed
  • Implement geo-routing

Performance Monitoring​

Key Metrics​

  1. Core Web Vitals

    • Largest Contentful Paint (LCP)
    • First Input Delay (FID)
    • Cumulative Layout Shift (CLS)

  2. Additional Metrics

    • Time to First Byte (TTFB)
    • First Contentful Paint (FCP)
    • Total Blocking Time (TBT)

Advanced Optimization Techniques​

Resource Hints​

layouts/partials/head.html
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preload" href="/fonts/main.woff2" as="font" type="font/woff2" crossorigin>

Critical CSS​

Inline critical styles for faster rendering:

layouts/partials/critical-css.html
<style>
  /* Critical CSS here */
  .hero { /* ... */ }
  .nav { /* ... */ }
</style>

SEO Optimization​

  1. Structured Data
  2. XML Sitemaps
  3. Meta Tags
