Server-Side Rendering vs Static Generation: What Your Business Needs
Rendering Strategies Matter
How your website renders content fundamentally impacts performance, SEO, and user experience. The two primary approaches — Server-Side Rendering (SSR) and Static Site Generation (SSG) — each have distinct advantages for different use cases.
Server-Side Rendering (SSR)
SSR generates HTML on each request. The server processes the request, fetches data, renders the page, and sends complete HTML to the browser. This ensures content is always fresh and fully crawlable by search engines.
When SSR Excels
SSR is ideal for dynamic, personalised content: dashboards, e-commerce with real-time inventory, social feeds, and any page where content changes frequently or varies per user. The trade-off is slightly slower response times due to server processing.
Static Site Generation (SSG)
SSG pre-renders pages at build time, producing static HTML files served from a CDN. This results in near-instant page loads and minimal server costs. Content is baked in during the build process.
When SSG Excels
SSG is perfect for content that doesn't change frequently: marketing sites, blogs, documentation, and landing pages. Pages load in milliseconds because they're served as pre-built files from edge locations worldwide.
The Hybrid Approach
Modern frameworks like Next.js allow mixing SSR and SSG within the same application. Your marketing pages can be statically generated while your dashboard uses server-side rendering. This gives you the best of both worlds.
Making the Decision
Consider your content update frequency, personalisation requirements, traffic patterns, and budget. Most business websites benefit from SSG for marketing pages and SSR for dynamic sections — a pattern that delivers both speed and flexibility.
