Static Site Generation (SSG)
Static Site Generation (SSG) is a rendering strategy where pages are pre-rendered as static HTML files at build time, served directly from a CDN without server computation on each request.
SSG produces the fastest possible pages — pre-built HTML served from edge CDN locations worldwide. TTFB is minimal because there is no server-side computation. This is ideal for content that does not change between requests: landing pages, blog posts, documentation, and glossary pages.
The limitation is that content is only updated when you rebuild and redeploy. For pages that need fresh data (dashboards, user-specific content), use SSR or ISR instead. In Next.js, pages without dynamic data fetching are automatically statically generated.
Use `generateStaticParams()` in Next.js to pre-render dynamic routes at build time. This is the recommended approach for programmatic SEO pages like glossary terms, use-case pages, and blog posts. Indxel's landing pages and glossary use SSG for maximum performance.
Example
// Next.js App Router — SSG with dynamic routes
// app/glossary/[slug]/page.tsx
export async function generateStaticParams() {
return glossaryTerms.map((term) => ({
slug: term.slug,
}));
}
export default function GlossaryTermPage({
params,
}: {
params: { slug: string };
}) {
const term = glossaryTerms.find((t) => t.slug === params.slug);
return <article><h1>{term.term}</h1></article>;

Server-Side Rendering (SSR)
Server-side rendering (SSR) is a technique where the web server generates the complete HTML for a page on each request, sending fully rendered content to the browser and search engine crawlers.
Incremental Static Regeneration (ISR)
Incremental Static Regeneration (ISR) is a Next.js rendering strategy that allows statically generated pages to be updated after deployment, either on a timed schedule or on-demand, without a full rebuild.
Page Speed
Page speed is the measurement of how quickly a web page's content loads and becomes interactive, typically measured by metrics like Time to First Byte (TTFB), First Contentful Paint (FCP), and Largest Contentful Paint (LCP).
