SSR sends a fully rendered page to the client, improving load times and search engine visibility. We dive into how it works in frameworks like Next.js.

**What is Server-Side Rendering?**
Server-side rendering is a technique where the server generates the HTML for a page and sends it to the client. This differs from client-side rendering, where the client generates the HTML using JavaScript.

**Benefits of SSR:**
- **Improved Performance**: Faster initial page load times.
- **Better SEO**: Search engines can crawl the fully rendered page.
- **Accessibility**: Users with JavaScript disabled can still view the page.

**How SSR Works in Next.js:**
Next.js provides built-in support for server-side rendering. When a user requests a page, Next.js renders the page on the server and sends the HTML to the client.

**Use Cases for SSR:**
- **Content-Heavy Websites**: Blogs, news sites, and e-commerce sites.
- **SEO-Critical Pages**: Pages that need to rank well in search engines.
- **Slow Networks**: Pages that need to load quickly on slow networks.

**Key Considerations:**
- **Server Load**: SSR increases server load, so you need to ensure your server can handle the traffic.
- **Caching**: Implement caching strategies to reduce server load.
- **Data Fetching**: Ensure data is fetched on the server before rendering the page.

By understanding how SSR works and when to use it, you can create web applications that are fast, accessible, and SEO-friendly.
