Server-Side Rendering (SSR)

Server-side rendering is the pattern where the server generates the full HTML for a page before sending it to the client. The browser receives a complete, content-rich document on the first byte; JavaScript may run on top to add interactivity, but the page is fully readable without it. Frameworks like Next.js, Nuxt, Remix, SvelteKit, and Rails default to SSR for most pages because it ships fast first paints, performs well on slow devices, and is trivially scrapable by search engines and AI crawlers. For scraping and AI ingestion, SSR pages are the easy case. A plain HTTP fetch returns HTML containing all the content the user would see. No headless browser, no JavaScript execution, no waiting for network activity to settle. Scraping cost stays low and reliability stays high. Sites that publish public information — news, documentation, product catalogs, government data — overwhelmingly use SSR for exactly this reason. For AI builders running content sites, choosing SSR over CSR is one of the highest-leverage decisions for SEO and AI visibility. AI Overview and AI search citations disproportionately favor SSR sites because the content is unambiguously available to crawlers. Static export (a special case of SSR where every page is pre-built) is even better — the same content is served from a CDN with no server compute per request.
