What is Static Site Generation (SSG)?
Pre-rendering pages at build time so they can be served instantly from a CDN without a server.
SSG generates HTML for each page during the build step. The pages are served as static files from a CDN — the fastest possible delivery. In Next.js, use generateStaticParams() to tell the build which pages to pre-render. Best for content that doesn't change per-request: blog posts, marketing pages, documentation.
