Semalt Expert descreve as principais ferramentas de extração da Web

Nov 29, 2017

Para alguns desenvolvedores de sites, é essencial para automatizar algumas ferramentas de extração da web. Eles ajudam uma pessoa a colher dados do site de um site e armazená-lo em um local remoto ou em um disco rígido físico. As pessoas odeiam a opção popular de salvar dados da página de uma página da web usando um navegador. No entanto, alguns sites têm muitas páginas. Uma pessoa pode usar uma ferramenta de extração da Web para salvar várias páginas de uma vez. A maioria dessas ferramentas oferece serviços de automação, como a configuração de um cronograma consistente pré-definido. Essas ferramentas funcionam exatamente como navegadores padrão, exceto por serem rastreadores web simples que visitam páginas da web e coletam dados essenciais.

Neste artigo de SEO, algumas das ferramentas de extração de internet mais influentes estão presentes:

Octoparse

Esta é uma ferramenta de extração de tela visual que pode baixar as informações do site. O usuário tem a vantagem da interface fácil de usar que vem com muitos recursos. Pessoas com nenhum know-how de programação mínimo podem usar o Octoparse para permitir a extração de dados a partir de um URL alvo.

Hubdoc

Um raspador da Web pode querer obter dados de faturas, recibos e e-mails. Em todos esses casos, o Hubdoc pode rastrear e coletar essas informações para um domínio alvo. A partir daqui, esta ferramenta pode ser capaz de armazenar os dados de forma estruturada para futuras referências..

Winautomação

Para usuários do Windows, o WinAutomation facilita o desenvolvimento de conteúdo para seus sites. Ele permite que os usuários do Windows obtenham uma ferramenta automática que pode ser capaz de salvar, bem como criar um diretório estruturado de dados de um site em uma unidade local.

Health Data Archiver

Ao considerar as ferramentas de extração de internet hospitalares, o Health Data Archiver ajuda os usuários a extrair dados de sites de sistemas de saúde. É possível usar essas informações como hospitais e ambulâncias e serviços médicos. Para usuários que precisam de serviços ETL, o Health Data Archiver ajuda a automatizar a coleta de dados de URLs médicos específicos para uso em seus sistemas.

Diggernaut

Esta ferramenta oferece uma solução fácil para destruição de dados do site. Os usuários que possuem conhecimento de programação mínimo ou zero podem recuperar dados do site e salvá-lo. A Diggernaut possui uma interface de usuário simples, bem como recursos simples de arrastar e soltar.

Salestools.io

Para usuários que desejam gerar vendas, você pode obter dados precisos usando ferramentas como Salestools.io. Esta ferramenta tem a opção de buscar dados de um site concorrente. Além disso, pode-se interagir com o esquema de marketing do site concorrente.

Integração de dados

Em algumas necessidades de desmantelamento, as APIs podem ser incompatíveis. Nesses casos, os dados em movimento entre requisitos em tempo real ou de transmissão podem ser possíveis usando a ferramenta de integração de dados.

Datahut

As empresas podem usar o Datahut para se preparar para usar o conteúdo da empresa. Algumas pessoas podem querer realizar uma análise comercial específica. Datahut é uma ferramenta de extração da Web que faz com que os usuários baixem dados do site em um flash. As pessoas que iniciam o comércio eletrônico podem se beneficiar com este aplicativo.
