Next.js lets developers render pages on the server (SSR) or at build time (SSG), making content immediately available to search engines while improving performance metrics that matter for SEO. These features allow pages to load faster and be indexed more efficiently, which helps search ranking and user experience.

Next.js is designed for flexible rendering. For dynamic content like dashboards or user feeds, server-side rendering keeps data fresh. For mostly static content like blogs or landing pages, static generation makes load times extremely fast — both benefiting performance and search visibility.
