Server-side rendering means the HTML for a page is produced on the server and sent complete to the browser, rather than being assembled in the browser by JavaScript after the page loads.
A server-rendered page arrives as readable HTML: content is present in the initial response. A client-rendered page arrives as a near-empty shell plus instructions, and the content exists only once JavaScript has run.
Search engines can execute JavaScript, but do so on a delay and inconsistently. Many AI crawlers execute little or none, which means client-only content can be effectively invisible to exactly the systems that increasingly decide whether a business is found.
A server-rendered page shows content as soon as it arrives; a client-rendered one shows a blank area or a spinner until the bundle downloads, parses and executes, worst on the slower devices most visitors actually use.
It is an argument about where the first render happens. Modern frameworks render on the server and enhance in the browser, which gives both machine readability and interactivity.
Google can, on a delay and not always completely. Many AI crawlers do far less, or none. Content that exists only after JavaScript runs is at real risk of being invisible to the systems that assemble answers.
For the visitor, usually the opposite: content appears without waiting for a bundle to download and execute. It puts more work on the server, which is a cost question rather than a user-experience one.
