The Technical Challenge
In the modern web, “speed” is no longer just a luxury it’s a ranking factor. With Google’s emphasis on Core Web Vitals (LCP, FID, CLS), dynamic sites often struggle with high Time to First Byte (TTFB) and unpredictable layout shifts caused by heavy JavaScript hydration.
Architecture & Strategy: Why Static?
I choose a static-first approach using Hugo because it shifts the computation from the request time to the build time.
Key Advantages:
- 0ms Server Logic: Every page is a pre-rendered HTML file served directly from a CDN (GitHub Pages).
- Predictable Performance: No database queries or server-side rendering (SSR) delays.
- Security: Zero attack surface for SQL injection or server-side exploits.
// Example of how we audit performance via Navigation Timing API
window.addEventListener('load', () => {
const perfData = window.performance.getEntriesByType("navigation")[0];
console.log(`Server Response Time (TTFB): ${perfData.responseStart - perfData.requestStart}ms`);
});
Implementation Details
By utilizing Hugo’s asset pipeline, I automate the minification of CSS and the management of critical rendering paths. This ensures that the browser receives only the necessary bytes to render the “above-the-fold” content instantly.
The Results
The result is a portfolio that achieves:
- LCP: < 0.8s
- CLS: 0
- SEO: Perfect crawlability for search engine bots.
Summary & Key Takeaways
Winning at SEO requires a foundation of performance. By eliminating technical debt and choosing static-first architectures, we build products that users love and search engines prioritize.
