Renderizado dinámico como solución alternativa
En algunos sitios web, JavaScript carga contenido adicional cuando la página está abierta en un navegador. Este proceso se denomina procesamiento del lado del cliente. La Búsqueda de Google ve este contenido junto con el contenido del HTML de un sitio web. Ten en cuenta que hay algunas limitaciones de JavaScript en la Búsqueda de Google y que algunas páginas pueden tener problemas que hagan que no se muestre el contenido en el HTML renderizado. Otros buscadores pueden elegir ignorar JavaScript, por lo que no verán contenido generado por JavaScript.
El renderizado dinámico es una solución temporal para los sitios web en los que el contenido generado por JavaScript no está disponible en los buscadores. Los servidores de renderizado dinámico detectan los robots que pueden tener problemas con el contenido generado por JavaScript y sirve una versión renderizada del servidor a esos robots, a la vez que muestra la versión renderizada del cliente a los usuarios.
El renderizado dinámico es una solución provisional, y no una solución recomendada, porque crea complejidades y requisitos de recursos adicionales.
El renderizado dinámico requiere que tu servidor web detecte rastreadores (por ejemplo, comprobando el user-agent). Cuando tu servidor web identifica una solicitud de un rastreador que no es compatible con JavaScript o con las funciones de JavaScript necesarias para renderizar tu contenido, esta solicitud se dirige a un servidor de renderizado. Las solicitudes de los usuarios y los rastreadores sin problemas de JavaScript se sirven de forma normal. El servidor de renderizado responde a las solicitudes con una versión del contenido adecuada para el rastreador, como una versión HTML estática. Puedes optar por habilitar el renderizado dinámico en todas las páginas o por página.
El renderizado dinámico no es encubrimiento
El robot de Google no suele considerar el renderizado dinámico como encubrimiento. Siempre que tu renderizado dinámico produzca contenido similar, el robot de Google no considerará que el renderizado dinámico es encubrimiento.
La práctica de usar el renderizado dinámico para servir contenido completamente diferente a usuarios y rastreadores puede considerarse encubrimiento; por ejemplo, si sirve una página sobre gatos a los usuarios y una sobre perros a los rastreadores.

Instead, we recommend that you use [server-side rendering](https://web.dev/articles/rendering-on-the-web#server-side), [static rendering](https://web.dev/articles/rendering-on-the-web#static), or [hydration](https://web.dev/articles/rendering-on-the-web#rehydration) as a solution.\n\n\nOn some websites, JavaScript loads additional content when the page is open in a browser.\nThis is called [client-side rendering](https://web.dev/articles/rendering-on-the-web#client-side). Google Search sees this content along with the content in the HTML of a website. Keep in mind that there are some [limitations for JavaScript in Google Search](/search/docs/crawling-indexing/javascript/javascript-seo-basics#write-compatible-code)\nand some pages may encounter problems with content not showing up in the rendered HTML. Other search engines may choose to ignore JavaScript and won't see JavaScript-generated content.\n\n\nDynamic rendering is a workaround for websites where JavaScript-generated content is not available to search engines.\nA dynamic rendering server detects bots that may have problems with JavaScript-generated content and serves a server-rendered version\nwithout JavaScript to these bots while showing the client-side rendered version of the content to users.\n\n\nDynamic rendering is a workaround and not a recommended solution, because it creates additional complexities and resource requirements. \n\nSites that might use dynamic rendering\n\n\nDynamic rendering was a workaround for indexable, public JavaScript-generated content that changes rapidly, or\ncontent that uses [JavaScript features that aren't supported by the crawlers](/search/docs/guides/rendering)\nyou care about. Not all sites need to use dynamic rendering, and there are better solutions than dynamic rendering as explained in\n[an overview of rendering on the web](https://web.dev/articles/rendering-on-the-web).\n\nUnderstand how dynamic rendering works\n\n\nDynamic rendering requires your web server to detect crawlers (for example, by checking the\nuser agent). When your web server identifies a request from a crawler that does not support JavaScript or the JavaScript features required to render your content,\nthis request is routed to a rendering server. Requests from users and crawlers without JavaScript issues are served normally.\nThe rendering server responds to requests with a version of the content that's suitable to the crawler, for example, it may serve a static HTML version.\nYou can choose to enable the dynamic renderer for all pages or on a per-page basis.\n\nDynamic rendering is not cloaking\n\n\nGooglebot generally doesn't consider dynamic rendering as [cloaking](/search/docs/essentials/spam-policies#cloaking).\nAs long as your dynamic rendering produces similar content, Googlebot won't view dynamic rendering as cloaking.\n\n\nWhen you're setting up dynamic rendering, your site may produce error pages. Googlebot doesn't consider these error pages as cloaking and [treats the error as any other error page](/search/docs/crawling-indexing/javascript/javascript-seo-basics#use-meaningful-http-status-codes).\n\n\nUsing dynamic rendering to serve completely different content to users and crawlers can be considered cloaking.\nFor example, a website that serves a page about cats to users and a page about dogs to crawlers is cloaking."]]
