Búsqueda de anuncios o palabras clave con direcciones URL rotas

  • Artículo

Esta solución muestra cómo comprobar si hay anuncios o palabras clave con direcciones URL rotas. El script realiza la comprobación de todos los anuncios o palabras clave de las cuentas a las que el usuario tiene acceso. A continuación se muestra el flujo de alto nivel del script. Para obtener más información, lea los comentarios insertados.

  • Antes de ejecutar, establezca las variables NOTIFY y ENTITY_NAME. Establezca la variable NOTIFY en la lista de direcciones de correo electrónico a las que desea enviar los resultados del script. Y establezca la variable ENTITY_NAME para especificar si desea comprobar anuncios o palabras clave (el valor predeterminado es anuncios).
  • Lee un archivo de Google Drive. El archivo contiene una lista de objetos. Cada objeto contiene un identificador de cuenta y una marca de tiempo de la última vez que se comprobaron las direcciones URL rotas de la cuenta. La primera vez que el script ejecuta el archivo no debe existir. Si el archivo no existe, el script compila la lista completa de cuentas a las que el usuario tiene acceso. Tenga en cuenta que el script no recogerá las cuentas nuevas que se agregaron después de compilar el archivo. Si se agregaron cuentas, debe eliminar el archivo, por lo que genera una nueva lista de cuentas.
  • Ordena la lista de cuentas para que las cuentas que no se hayan comprobado o que sean las más antiguas se muestren primero.
  • Obtiene hasta los primeros 50 identificadores de cuenta de la lista y llama al método executeInParallel del selector. El método ejecuta en paralelo la findBrokenUrls función para cada cuenta. Esta función devuelve un objeto que contiene la información de la cuenta y la lista de anuncios o palabras clave con direcciones URL rotas, si las hay.
  • Ejecuta la reportResults función una vez completadas todas las llamadas a la findBrokenUrls función. Esta función crea una hoja de cálculo y usa Hojas de cálculo de Google para crear una hoja para cada cuenta. Si la cuenta contiene anuncios o palabras clave con direcciones URL rotas, escribe la entidad en la hoja.
  • Usa Google Mail para enviar una notificación por correo electrónico a los destinatarios especificados. El correo electrónico indica si una cuenta contiene direcciones URL rotas y proporciona un vínculo a la hoja donde puede ver los detalles.
  • Novedades el lastChecked campo de cada cuenta y guarda el archivo. La próxima vez que se ejecute el script, ordenará la lista de cuentas por la lastChecked marca de tiempo. Esto significa que todas las cuentas que no se hayan procesado o que sean las más antiguas serán las primeras de la lista. Este script tendrá que ejecutarse una o varias veces en función del número de cuentas que tenga.
