Semalt: Come ottenere dati da un sito Web - Tre diverse opzioni per te

Una grande quantità di dati viene caricata o condivisa su Internet ogni giorno, e consente agli imprenditori di conoscere meglio i loro prodotti, le tendenze del mercato, i concorrenti e i clienti. Come si possono ottenere dati da un sito Web? Per prendere la giusta decisione aziendale, è necessario affidarsi a strumenti specifici per lo scraping dei dati che consentono di eseguire più attività contemporaneamente. Cerchiamo di verificare diverse opzioni per ottenere dati da un sito web.

 1. Writing Codes 

Questa opzione è adatta per programmatori e sviluppatori. Se sei uno sviluppatore professionista o programmatore e possiedi conoscenze tecniche, puoi facilmente utilizzare diversi codici per ottenere dati da un sito web. Puoi imparare linguaggi come Python, C ++, JavaScript, Ruby per costruire i tuoi web scrapers ed estrattori di dati. Dovresti anche conoscere diverse librerie e framework Python per facilitare il tuo lavoro. Sfortunatamente, non è una buona opzione per coloro che non dispongono di conoscenze tecniche o non hanno alcuna presa sui vari linguaggi di programmazione. I framework che devi conoscere sono Selenium IDE, PhantomJS, Scrapy e altri. Quindi, se stai cercando di raccogliere dati dalla rete su base regolare (come recensioni da eBay e Amazon), vale la pena creare un raschietto web usando JavaScript. In alternativa, puoi usare Scrapy per portare a termine le tue attività.

 2. Strumenti speciali 

Esistono diversi strumenti per ottenere dati da un sito Web. Alcuni di questi sono adatti per programmatori e sviluppatori, mentre gli altri sono adatti a curatori di contenuti e aziende di piccole dimensioni. Questa opzione aiuta a ridurre gli ostacoli tecnici per ottenere contenuti web. Fortunatamente, la maggior parte degli strumenti di scraping Web sono economici e possono essere scaricati da Internet all'istante. Tieni presente che alcuni servizi di scraping dei dati richiedono una corretta manutenzione e configurazione. Kimono Labs, Import.io, Mozenda, Outwit Hub, Connotate, Kapow Software e Octoparse ti consentono di ottenere facilmente i dati da un sito web. Questi sono strumenti adatti al budget e sono compatibili con tutti i sistemi operativi e browser web.

 3. Data Analytics 

È una delle opzioni più recenti ed è adatta per i webmaster che hanno un budget e vogliono prestare attenzione all'analisi dei dati piuttosto che gestirne processi di raccolta dati. Qui, dovrai specificare gli URL di destinazione, lo schema dei dati (come i nomi dei prodotti, i prezzi e le descrizioni) e la frequenza di aggiornamento (settimanale, mensile o giornaliera) e ottenere i contenuti in base alle tue esigenze.

Speriamo che queste tre opzioni ti aiutino a prendere la giusta decisione e a migliorare il posizionamento nei motori di ricerca del tuo sito, ottenendo molti clienti e generando maggiori entrate per la tua azienda.
