Nov 30, 2017

A raspagem de dados da Web envolve a segmentação de dados novos e existentes de um site e armazená-lo em bancos de dados de mecanismos de pesquisa para facilitar o acesso. É verdade que as ferramentas de raspagem da web estão ganhando popularidade com o tempo porque um rastreador da web automatizou e simplificou todo o procedimento de rastreamento para tornar acessíveis os recursos de dados da Web a todos os usuários de internet. Algumas ferramentas de rastreador da Web permitem que os usuários indexem ou rastreiam seus sites ou blogs de forma metódica e eficaz, sem necessidade de códigos. Eles também transformam os dados em diferentes formatos e se adequam aos requisitos dos usuários. Aqui discutimos algumas excelentes ferramentas de rastreador da web para raspar sites e blogs.

3. Outubro

Este programa usa algumas opções para rasgar seu site de uma maneira melhor e tem amplas funcionalidades para se beneficiar.

Você pode baixar seu site em segundos usando esta ferramenta abrangente. Além disso, você pode salvar sites em diferentes formatos bem estruturados, como Excel, HTML e texto.

4. Getleft

O Getleft é um programa fácil de usar que ajuda a rasgar um blog ou site instantaneamente. Ele irá baixar todo o seu site e tem várias opções para se beneficiar. Você também pode inserir o URL e selecionar os arquivos que você deseja baixar no seu sistema de computador. Este programa é um dos melhores porque ele vem em 15 idiomas diferentes, tem suporte 24 horas por dia, 7 dias por semana, e torna sua experiência de navegação maravilhosa e excelente.
