Dynamic Rendering
Dynamic rendering is a web development technique where different content is served to users and search engine crawlers based on the client's user-agent. It typically involves detecting bots (like Googlebot) and serving them a pre-rendered static version of the page, while regular users receive the normal client-side rendered content. This approach helps solve SEO challenges for JavaScript-heavy applications by ensuring search engines can crawl and index content effectively.
Developers should use dynamic rendering when building single-page applications (SPAs) with frameworks like React, Angular, or Vue that rely heavily on client-side JavaScript, as search engines may struggle to index such content. It's particularly useful for content that changes frequently or requires real-time data, where server-side rendering might be too resource-intensive. This technique ensures better search engine visibility without sacrificing the user experience of dynamic web apps.
