Semalt Advice - Un servicio de raspado de pantallas basado en la nube

Feb 06, 2018

El raspado de pantalla se refiere a una técnica utilizada para extraer datos de sitios web y a veces se confunde con raspado de contenido, que es el uso de medios manuales y automáticos para recolectar contenido de sitios web sin la aprobación de un webmaster. Los raspadores de pantalla están destinados a extraer información de Internet y facilitar el proceso de rastreo. Están hechos en JavaScript, Python, Ruby, C ++, PHP, Ruby y otros lenguajes de programación y también son conocidos como cosechadores web y extractores de datos.

PromptCloud - Un servicio confiable de raspado de pantalla:

PromptCloud es conocido por su rastreo web interactivo y características de raspado de datos personalizadas. Nos permite raspar información de internet en más de 110 idiomas. Además, podemos rastrear nuestro contenido web y mejorar la clasificación de los motores de búsqueda de los sitios. Es posible guardar datos en la base de datos de PromptCloud o descargarlos a nuestro disco duro para usos fuera de línea. Puede dirigirse fácilmente a los foros de discusión, revisar sitios web, redes sociales, portales de viajes, sitios de comercio electrónico y sitios de noticias con este raspador de pantalla basado en la nube. PromptCloud es capaz de rastrear e indexar sus páginas web y hace que su contenido sea visible en los resultados de Google, Bing y Yahoo.

Fundada en 2009, PromptCloud es una empresa pionera y líder mundial en soluciones de datos como servicio. Una parte integral de su trabajo es la extracción de datos, que se realiza con diversas tecnologías de computación en la nube. PromptCloud ayuda a las empresas y programadores a adquirir datos estructurados de Internet. Sus funciones de extracción de datos son adecuadas para las principales marcas de una variedad de dominios que incluyen finanzas, viajes, marketing, atención médica, análisis y otros.

1. Capture las estructuras de contenido con PromptCloud:

Una de las características más distintivas de PromptCloud es que ayuda a capturar diferentes estructuras de contenido y facilita el raspado de la información. Por ejemplo, puede usar PromptCloud para datos de raspado de sitios de comercio electrónico y obtener información de precios, imágenes y descripciones de productos para su propio sitio web. Este raspador de pantalla mantendrá la calidad de sus datos y los descargará a su disco duro tan pronto como se complete el proceso.

2. Optimice su sitio con esta herramienta:

PromptCloud es uno de los mejores rastreadores web en Internet. Ayuda a optimizar su sitio y mejora su escalabilidad y confiabilidad. Estas características son importantes si desea extraer datos de cientos a miles de páginas web.

3. Importa datos a diferentes formatos:

Una vez que se completa el raspado de datos, PromptCloud importará la información a formatos CSV y JSON. También brinda la posibilidad de guardar sus datos en Google Drive, Dropbox y Box.net. Alternativamente, puede copiarlo en una disquetera o descargarlo a su disco duro para usarlo posteriormente. Una consulta de entrada de archivo y base de datos CSV ayuda a alimentar los valores de entrada a un formulario web, por lo que puede crear fácilmente los archivos CSV con cientos de palabras clave y enviar los formularios de búsqueda para palabras clave individuales.

Casi todos los raspadores de pantalla primitivos no le permiten extraer información de sitios dinámicos y sitios web de comercio electrónico. Con PromptCloud, puede dirigirse a todos los sitios web complejos y dinámicos e incluso puede orientar los sitios con AJAX, cookies, redirecciones y JavaScript.
