Un subdominio es una secci\u00f3n independiente de tu dominio principal que funciona como si fuera una p\u00e1gina web propia, utilizando un prefijo delante de tu nombre de dominio. Algunos ejemplos habituales son blog.tudominio.com<\/em>, tienda.tudominio.com<\/em>, o support.tu-dominio.com<\/em>. Los subdominios se pueden crear de forma gratuita con tu dominio actual y son una forma ordenada de organizar las diferentes partes de tu presencia en Internet sin necesidad de registrar un dominio nuevo.<\/p>\n

\u00bfPor qu\u00e9 utilizar un subdominio?<\/h2>\n

Los subdominios te permiten mantener separados los contenidos relacionados pero distintos, tanto para los visitantes como para los motores de b\u00fasqueda. Resultan \u00fatiles cuando una secci\u00f3n de tu sitio web tiene su propio objetivo, p\u00fablico o software. Entre sus usos habituales se incluyen:<\/p>\n

    \n
  • Un blog:<\/strong> blog.tudominio.com, separado de tus p\u00e1ginas principales de marketing.<\/li>\n
  • Una tienda en l\u00ednea:<\/strong> shop.tudominio.com, que utiliza un software de comercio electr\u00f3nico.<\/li>\n
  • Un centro de ayuda:<\/strong> support.tudominio.com o docs.tudominio.com.<\/li>\n
  • Un entorno de prueba o de desarrollo:<\/strong> dev.tu-dominio.com para probar los cambios de forma segura.<\/li>\n<\/ul>\n

    Dado que un subdominio puede ejecutar su propia aplicaci\u00f3n, puedes, por ejemplo, alojar WordPress en tu dominio principal y una herramienta completamente diferente en un subdominio.<\/p>\n

    C\u00f3mo crear un subdominio<\/h2>\n

    Crear un subdominio solo te llevar\u00e1 un minuto desde tu panel de control. Los nombres exactos var\u00edan ligeramente entre DirectAdmin y cPanel, pero el proceso es el mismo:<\/p>\n

      \n
    • Inicia sesi\u00f3n en tu panel de control.<\/li>\n
    • Abra el Subdominios<\/strong> o Dominios<\/strong> secci\u00f3n.<\/li>\n
    • Introduce el prefijo que desees, por ejemplo: blog<\/em>.<\/li>\n
    • Confirma la carpeta (ra\u00edz de documentos) en la que se almacenar\u00e1n sus archivos.<\/li>\n
    • Guarda y se crear\u00e1 el subdominio.<\/li>\n<\/ul>\n

      Tu panel de control a\u00f1ade autom\u00e1ticamente el registro DNS necesario para que el subdominio se resuelva, por lo que normalmente no hay que configurar nada m\u00e1s.<\/p>\n

      A\u00f1adir contenido a tu subdominio<\/h2>\n

      Cada subdominio tiene su propia carpeta en el servidor. Para configurarlo, sube los archivos a esa carpeta o instala all\u00ed una aplicaci\u00f3n. Si quieres instalar WordPress en tu subdominio, puedes utilizar un instalador de un solo clic y simplemente seleccionar el subdominio como ubicaci\u00f3n de instalaci\u00f3n. Recuerda activar el protocolo SSL para el subdominio, de modo que tambi\u00e9n se cargue de forma segura con el candado.<\/p>\n

      Subdominio frente a subcarpeta<\/h2>\n

      Quiz\u00e1 te preguntes si es mejor utilizar un subdominio (blog.tudominio.com) o una subcarpeta (tudominio.com\/blog). Ambas opciones son v\u00e1lidas. Una subcarpeta mantiene todo dentro de un mismo sitio web y suele ser m\u00e1s sencilla desde el punto de vista del SEO, mientras que un subdominio es m\u00e1s adecuado cuando la secci\u00f3n debe funcionar de forma independiente o utilizar un software diferente. Elige en funci\u00f3n del grado de independencia que necesite esa secci\u00f3n.<\/p>\n

      Soluci\u00f3n de problemas<\/h2>\n
        \n
      • El subdominio no se carga:<\/strong> Espera un poco a que el registro DNS entre en vigor.<\/li>\n
      • Sin candado:<\/strong> emitir o renovar el certificado SSL del subdominio.<\/li>\n
      • Aparece un contenido incorrecto:<\/strong> Comprueba que los archivos se encuentren en la carpeta propia del subdominio.<\/li>\n<\/ul>\n
