Client-side rendering (CSR) is a web development approach where a page’s content is built dynamically in the user’s browser using JavaScript, rather than being fully generated on the server before delivery.
While modern search engines have improved significantly at rendering JavaScript, client-side rendered sites still carry higher risk of crawling and indexing delays or issues compared to server-side rendered alternatives, particularly for complex or heavily scripted pages.
Websites built with CSR-heavy frameworks often benefit from implementing server-side rendering or pre-rendering specifically for SEO purposes, ensuring search engines can reliably access full page content without relying entirely on JavaScript execution.
