# Server-Side Rendering

**Category:** CMS & Framework SEO | **Updated:** 2026-03-05

Server-Side Rendering (SSR) is a web rendering technique where HTML is generated on the server for each request, delivering fully rendered pages to browsers and search engine crawlers for immediate content access.

## What Is Server-Side Rendering?
Server-Side Rendering (SSR) is a technique where the web server generates the full HTML content of a page for each request before sending it to the client's browser. When a user or search engine crawler requests a page, the server executes JavaScript, fetches data, renders the React/Vue/Angular components to HTML, and returns a complete HTML document. The browser then "hydrates" the HTML to make it interactive.

## Why SSR Matters for SEO
SSR solves the fundamental JavaScript SEO problem: **search engines receive complete, rendered HTML** instead of an empty shell that requires JavaScript execution. While Google can render JavaScript, it's resource-intensive and can cause indexation delays. SSR ensures content is immediately visible to all crawlers, including those with limited JavaScript capabilities (Bing, Yandex, social media crawlers). SSR also improves First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

## When to Use SSR
Use SSR for pages that need to be indexed and have dynamic/personalized content (user-specific pages, real-time data). For static content, prefer Static Site Generation (SSG) as it's faster and cheaper. Frameworks supporting SSR: Next.js (React), Nuxt (Vue), SvelteKit (Svelte), Astro.
