Semalt: il software più interessante per il raschiamento di URL

Lo scraping di URL è un processo di estrazione di dati da URL diversi e filtraggio come da requisiti. Ci sono centinaia di URL di siti Web su Internet e un raschietto di URL è in grado di ricavare informazioni utili da loro senza compromettere la qualità. Le caratteristiche ricercate di un raschietto URL variano in base alle tue esigenze e all'obiettivo del tuo progetto. Devi assicurarti che il tuo software di scraping di URL possieda tutte le funzionalità di base: filtraggio basato sul contenuto delle parole chiave, rotazione del proxy, filtro basato sul profilo del sito web e filtro basato sul codice HTML.

I migliori e più sorprendenti software di scrap scrap sono discussi di seguito:

 1. URLitor - URL Scraping and Data Extraction Tool 

URLitor è uno dei migliori e più famosi strumenti per l'estrazione di dati e lo scraping di URL su Internet. Devi solo aggiungere l'elenco di URL, specificare gli elementi HTML che vuoi recuperare da una pagina web e premere il pulsante Invia. Una delle caratteristiche più distintive di questo strumento è che usa espressioni regolari e XPath per eseguire i suoi compiti. È possibile selezionare diversi formati di output e raschiare il numero di URL o di documenti Web che si desidera. Inoltre, questo strumento è adatto a coloro che non hanno sufficienti capacità di programmazione e mancano di conoscenze tecniche. Questo strumento può racchiudere fino a 100 URL in un minuto senza compromettere la qualità.

 2. Raschietto 

Raschietto è uno dei migliori strumenti di raschiamento del nastro e di estrazione dei dati sulla rete. È facile da usare ed è compatibile con tutti i sistemi operativi e browser web. Scraper è la scelta prioritaria di programmatori e webmaster perché consente di estrarre più URL alla volta. Puoi utilizzare questo strumento solo quando hai Google Chrome come browser web principale. Altrimenti, Scraper non estrarrà correttamente le tue pagine web o URL. Scraper può farti amare lo scraping dei dati fornendo risultati accurati e affidabili. È possibile personalizzare Scraper utilizzando Colonne, Filtro e XPath.

 3. API Facebook e Twitter 

Se stai cercando di rasentare gli URL di Twitter o Facebook, le API di Facebook e Twitter sono perfette per te. Queste API possono essere utilizzate per raccogliere enormi quantità di dati dai profili pubblici. Puoi anche analizzare o valutare ciò che funziona per i concorrenti o nel tuo settore. Un'API è un'interfaccia che consente agli strumenti o software di terze parti di accedere ai tuoi siti di social media a livello di programmazione.

 4. Import.io 

Import.io è uno dei migliori e più potenti strumenti di estrazione di URL o di raschiamento di URL. Ha un'interfaccia user-friendly e puoi usarlo per raschiare più pagine web o URL alla volta. È inoltre possibile creare un'API per l'integrazione in diverse applicazioni Web. Con Import.io, puoi facilmente estrarre informazioni da siti sia dinamici che semplici e ottenere risultati leggibili e scalabili. Import.io non richiede alcuna configurazione e fornisce risultati in pochi secondi.
