Semalt compartilha um tutorial da Web Scraper para impulsionar seu negócio on-line

        

Quando se trata de desmantelar, ter uma compreensão mais profunda do HTML e do HTTP é de extrema importância. Para iniciantes, a raspagem, também conhecida como rastreamento, refere-se a puxar conteúdo, imagens e dados cruciais de outro site. Nos últimos meses, os webmasters têm feito perguntas sobre o uso de programas e a interface do usuário na raspagem na web.

A raspagem da Web é uma tarefa do-it-yourself que pode ser executada usando uma máquina local. Para iniciantes, a compreensão dos tutoriais do scraper da Web ajudará você a extrair conteúdo e textos de outros sites sem encontrar problemas. Os resultados obtidos de vários sites de comércio eletrônico são comumente armazenados em conjuntos de dados ou formas de arquivos de registro.   

Uma estrutura de rastreamento web útil é uma ferramenta essencial para webmasters. Uma boa estrutura de trabalho ajuda os profissionais de marketing a obter conteúdo e descrições de produtos amplamente utilizados pelas lojas online.

Aqui estão as ferramentas que o ajudarão a extrair informações e credenciais valiosas dos sites de comércio eletrônico.

Ferramentas baseadas em Firebug

Ter uma compreensão mais profunda das ferramentas do Firebug irá ajudá-lo a recuperar ferramentas dos sites desejados facilmente. Para extrair dados de um site, você precisa traçar planos bem definidos e estar familiarizado com os sites a serem usados. O tutorial da Web Scraper é composto por um guia de procedimentos que ajuda os profissionais de marketing a mapear e extrair dados de sites grandes.

Como os cookies passam em um site também determinam o sucesso do seu projeto de raspagem na web..Realize uma pesquisa rápida para entender HTTP e HTML. Para webmasters que preferem usar um teclado em vez de um mouse, o mitmproxy é a melhor ferramenta e console para usar.

Abordagem para sites com JavaScript

Quando se trata de raspar sites pesados de JavaScript, ter conhecimento de usar o software proxy e as ferramentas de desenvolvimento do Chrome não é uma opção. Na maioria dos casos, esses sites são uma mistura de respostas HTML e HTTP. Se você se colocar em tal situação, haverá duas soluções a serem tomadas. A primeira abordagem é determinar as respostas chamadas pelos sites JavaScript. Depois de identificar, os URLs e as respostas foram feitas. Resolva esse problema fazendo suas respostas e tenha cuidado ao usar os parâmetros certos.   

A segunda abordagem é muito mais fácil. Neste método, você não precisa descobrir os pedidos e as respostas feitas por um site JavaScript. Em palavras simples, não há necessidade de descobrir dados contidos em linguagem HTML. Por exemplo, os motores do navegador PhantomJS carregam uma página que executa o JavaScript e notifica um webmaster quando todas as chamadas do Ajax estão completas.

Para carregar o tipo certo de dados, você pode iniciar seu JavaScript e desencadear cliques efetivos. Você também pode iniciar o JavaScript para a página da qual deseja extrair dados e deixar o scrapper analisar os dados para você.

O comportamento do bot      

Comumente conhecido como limitação de taxa, o comportamento do bot remete consultores de marketing para limitar a quantidade de pedidos feitos em domínios direcionados. Para retirar dados de forma eficaz de um site de comércio eletrônico, considere manter sua taxa tão lenta quanto possível.

Teste de integração

Para evitar a salvaguarda de informações inúteis no seu banco de dados, recomenda-se que você integre e teste seus códigos com freqüência. O teste ajuda os comerciantes a validar dados e evitar a salvação de arquivos de registro corrompidos.

Ao raspar, observar questões éticas e aderir a elas é um pré-requisito necessário. A falta de políticas e os padrões do Google podem ajudá-lo em problemas reais. Este tutorial web scraper irá ajudá-lo a escrever sistemas de raspagem e facilmente sabotar bots e aranhas que podem comprometer sua campanha online.
