Dynamic Rendering

Definition

Serving a prerendered HTML version to crawlers while sending the JavaScript app to users.

Dynamic rendering detects crawler user agents and serves them a server-rendered, static snapshot of a page while human visitors receive the normal client-side application. It was promoted as a workaround for search engines that struggled with JavaScript, but Google now describes it as a stop-gap rather than a recommended long-term solution. Modern practice favours server-side or static rendering, since dynamic rendering adds maintenance overhead and risks content parity issues between the two versions.
