Semalt: Lo que necesitas saber sobre los sitios de raspadores

Web scraping es ampliamente utilizado para extraer información de sitios web de redes sociales basadas en carreras para encontrar el candidato adecuado para puestos vacantes específicos. Se recomienda buscar ofertas de trabajo disponibles en los mercados de trabajo mediante el uso de web scraping, que llenar solicitudes y enviarlas a los reclutadores. Existen miles de razones para extraer datos de la web en lugar de simplemente usar sitios web por motivos de navegación.

¿Qué es un sitio de raspado?

En la industria de marketing en línea actual, la web es la fuente más importante de datos útiles. Los sitios web muestran datos en un formato u otro. Aquí es donde interviene la extracción de datos web. Como profesional del marketing, debe recopilar datos de múltiples fuentes web para su análisis. Con las herramientas de raspado web actuales, puede extraer fácilmente grandes cantidades de datos de páginas web y exportar los datos a CouchDB o a la hoja de cálculo de Microsoft Excel.

Para aumentar la participación de los usuarios y generar tráfico externo, debe publicar contenido nuevo y original en su sitio web. Un sitio web que presenta información extraída de otros sitios web y que se presenta a los usuarios finales como nuevo y único se denomina sitio de raspado. Estos sitios obtienen datos de sitios web de comercio electrónico para republicar, analizar mercados y fines de investigación.

Web scraping ethics

Web scraping es la técnica para recuperar datos en grandes cantidades de formatos no estructurados y exportar los datos en formas bien documentadas que pueden leerse fácilmente por los visitantes potenciales de su sitio. Sin embargo, la mayoría de los sitios web de comercio electrónico utilizan directivas de "no permitir" en su archivo de configuración de robots.txt para evitar que los raspadores web raspen sus sitios. Recortar el contenido de los sitios dinámicos que no le permiten raspar se considera ilegal y puede provocarle un gran problema.

No necesita contratar a miles o millones de profesionales para copiar y pegar contenido de páginas web. Los raspadores de sitios son herramientas automatizadas de extracción de datos web que recopilan grandes cantidades de información de destino de las páginas web. Los datos obtenidos pueden exportarse fácilmente a hojas de cálculo. Tenga en cuenta que puede exportar contenido fragmentado a CouchDB para proyectos avanzados de web scraping.

Usos del raspado web

Los raspadores web extraen datos de los sitios web de comercio electrónico para diversos fines. Para rastrear el rendimiento de sus competidores en los mercados financieros, necesita acceso a datos completos y precisos. Aquí hay una lista de los usos de raspado web estándar.

  •  Investigación 

Los datos juegan un papel integral en la investigación de marketing, científica y académica. Con un raspador web eficiente, puede extraer grandes cantidades de datos de múltiples fuentes en un formato estructurado.

  •  Comparación de precios 

Las tiendas en línea confían en datos completos y precisos para comparar precios de productos y servicios ofrecidos por otras compañías que ofrecen la misma línea de productos. Los raspadores web ayudan a los propietarios de tiendas en línea a recopilar grandes cantidades de datos para comparar precios y mejorar las relaciones con los clientes.

  •  Generación de leads 

Los raspadores de sitios se pueden usar para extraer detalles de contacto de individuos y organizaciones de sitios web de comercio electrónico. Las credenciales como los números de teléfono, las URL de los sitios web y la dirección de correo electrónico se pueden recuperar de los sitios y volver a publicar en sitios de raspadores.

Raspar un sitio para crear una lista de contactos puede ser fácil. Sin embargo, crear una lista de contactos de miles de sitios que se actualizan constantemente puede ser una tarea engorrosa. La extracción de datos web es la mejor solución para obtener datos limpios, confiables y consistentes de la web.
