Server-Side Rendering
A technique where the server generates the full HTML for a page before sending it to the browser. The user (or bot) receives a complete, ready-to-read page without needing to execute JavaScript first.
Why Server-Side Rendering Matters for SEO
SSR is the most SEO-safe rendering approach for JavaScript-heavy sites. Search engines get fully rendered HTML on the first request, eliminating the risk of content being missed during Google's delayed rendering queue. It also improves perceived page speed.
How Server-Side Rendering Works
When a request comes in, the server runs the JavaScript framework (React, Vue, etc.), generates the HTML output, and sends the complete page. The browser can display content immediately while JavaScript hydrates for interactivity. Frameworks like Next.js and Nuxt.js make SSR straightforward to implement.
Common Mistakes
- Not implementing proper caching, causing slow server response times
- Forgetting to hydrate properly, leading to mismatches between server and client renders
- Over-engineering SSR for a simple content site that doesn't need a JS framework
