SSR和SSG通過在服務器或構建時生成完整HTML，顯著提升Vue應用的性能與SEO。首先，SSR在用戶首次訪問時即返回已渲染頁面，減少空白屏時間，加快感知加載速度；其次，SSG將頁面預渲染為靜態(tài)文件，簡化部署并加快內容呈現(xiàn)；第三，搜索引擎可直接抓取HTML中的內容與元數(shù)據(jù)，提升SEO效果；第四，Nuxt 3支持ISR，允許按需更新靜態(tài)頁面，兼顧性能與動態(tài)內容需求。這些方法共同優(yōu)化了首屏體驗、SEO表現(xiàn)及部署靈活性。

Server-side rendering (SSR) and static site generation (SSG), especially when using frameworks like Nuxt.js, can significantly improve both performance and SEO for Vue applications. These approaches address some of the key limitations of traditional client-side rendered (CSR) apps, particularly around initial load speed and search engine visibility.

Faster Initial Load Time

One of the biggest advantages of SSR and SSG is that they deliver fully-rendered HTML to the browser on the first load. In a standard Vue app built with Vue Router and rendered entirely on the client side, users often see a blank screen or loading spinner until JavaScript downloads, parses, and executes.

With SSR:

• The server processes the request and sends back a fully rendered page.
• Users see meaningful content almost immediately.
• This reduces perceived load time, which is crucial for user experience and retention.

With SSG:

• Pages are pre-rendered at build time and served as static files.
• There's no need to wait for JavaScript to run before seeing content.
• Hosting becomes simpler and faster since you're serving plain HTML files.

This early delivery of content means your Vue app feels snappier from the very first visit, especially on slower networks or devices.

Better SEO Out of the Box

Search engines like Google have improved their ability to execute JavaScript, but it's still not perfect or guaranteed. Some crawlers may not wait long enough for JS to finish running, or may miss dynamic content altogether.

Using SSR or SSG helps because:

• The HTML sent to the crawler already contains all the important content.
• Meta tags, headings, and structured data are present in the initial response.
• You avoid relying on search engines to render JavaScript-heavy pages correctly.

For example, if you're building a blog or e-commerce site with Vue, making sure each article or product page has proper title tags, descriptions, and Open Graph metadata in the initial HTML makes a big difference in how well those pages get indexed and ranked.

Nuxt.js also includes modules like @nuxtjs/seo that make it easier to manage meta information across pages without extra setup, further improving SEO performance.

Hybrid Flexibility with Incremental Static Regeneration (ISR)

While SSG traditionally meant rebuilding the entire site whenever content changes, Nuxt 3 and newer versions support more flexible strategies like ISR (available via Nitro or third-party integrations). This lets you:

• Pre-render pages ahead of time.
• Update them in the background as needed, without a full rebuild.
• Serve stale content temporarily while new versions generate.

This is especially useful for sites that have frequently updated content but still want the performance benefits of static hosting.

It's a middle ground between static generation and full server-side rendering—giving you control over when and how content updates happen without sacrificing performance.

In short, using SSR or SSG with Nuxt.js improves Vue application performance by delivering usable content faster and enhances SEO by ensuring crawlers get properly rendered HTML. It's not a magic bullet, but for many use cases, it's a solid upgrade over purely client-side rendering.
