How does Next.js handle SEO compared to a client-rendered SPA?

Q: How does Next.js handle SEO compared to a client-rendered SPA?

**TL;DR.** Because Next.js renders **HTML on the server** (SSR/SSG), crawlers get **fully-formed content and metadata on first request** — unlike a client-rendered SPA where bots may see an **empty shell** until JS runs. Plus the **Metadata API, sitemaps, and fast loads** boost rankings. SPA (CSR) empty <div id=root> content after JS weaker/slower for bots Next.js (SSR/SSG) <text class='d-sub'

What a crawler receives

# SPA (CSR): first response is basically empty
<body><div id="root"></div><script src="/bundle.js"></script></body>

# Next.js (SSR/SSG): first response has real content + metadata
<head><title>My Post | Site</title><meta property="og:title" ...></head>
<body><article><h1>My Post</h1><p>Full text here…</p></article></body>
