Server-Side Rendering (SSR)
Definition
Server-side rendering generates full HTML on the server for each request so browsers and crawlers receive content without waiting on client JavaScript.

In SSR architectures, the server runs application code (or templates), produces HTML, and sends it to the client. Users see meaningful content sooner; crawlers that do not fully execute JavaScript still receive the primary text and links.
SSR contrasts with pure client-side rendering, where an empty shell loads and JavaScript builds the DOM. Hybrids such as static generation and streaming SSR sit between those poles. Hydration may still attach interactivity after HTML arrives.
For SEO and AI retrieval, SSR or static HTML reduces the risk that important product or documentation text is invisible to simple fetchers. See Hydration, Render-Blocking Resources, and Indexability.
