Definition
Server-Side Rendering (SSR) is a web rendering technique where the server generates the complete HTML of the page before sending it to the browser. Unlike Client-Side Rendering where the browser receives minimal HTML and builds the page via JavaScript, SSR provides content that is immediately readable by search engines and users. Modern frameworks like Next.js (React), Nuxt.js (Vue), and Angular Universal facilitate SSR implementation. This approach is particularly beneficial for SEO as it guarantees fast and complete indexing.
Key Points
- Complete HTML generated on the server, ideal for SEO
- Popular frameworks: Next.js, Nuxt.js, Angular Universal
- Combines SEO benefits (content in HTML) with interactivity (JS hydration)
Practical Examples
Migration to Next.js
A React CSR site migrates to Next.js with SSR. Pages are now indexed within hours instead of days, and LCP improves by 40%.
E-commerce and SSR
An online store uses Nuxt.js with SSR for product pages, ensuring Google immediately indexes descriptions, prices, and reviews.
Frequently Asked Questions
Yes, SSR is significantly better for SEO because content is immediately available in the HTML without waiting for JavaScript rendering. Google indexes SSR pages faster and more completely.
SSR increases server load as each request generates HTML. This can increase TTFB. Hybrid solutions (ISR with Next.js) offer a good compromise between performance and server load.
