Esperto di Semalt dice come schermare raschiare un blog

Feb 08, 2018

Vuoi raschiare dati da internet? Stai cercando un web crawler affidabile? Un web crawler, noto anche come bot o spider, naviga sistematicamente su Internet allo scopo di indicizzare il web. I motori di ricerca utilizzano diversi spider, bot e crawler per aggiornare i loro contenuti web e classificare i siti sulla base delle informazioni fornite dai web crawler. Allo stesso modo, i webmaster usano diversi robot e spider per rendere più facile per i motori di ricerca classificare le loro pagine web.

Questi crawler consumano le risorse e indicizzano milioni di siti Web e blog su base giornaliera. Potrebbe essere necessario affrontare i problemi di caricamento e pianificazione quando i crawler Web dispongono di un'ampia raccolta di pagine per l'accesso.

I numeri delle pagine Web sono estremamente grandi e persino i migliori bot, spider e web crawler non riescono a fare un indice completo. Tuttavia, DeepCrawl rende facile per i webmaster e i motori di ricerca indicizzare pagine Web diverse.

Una panoramica di DeepCrawl:

DeepCrawl convalida diversi collegamenti ipertestuali e codice HTML. Viene utilizzato per analizzare i dati da Internet e per eseguire la scansione di pagine Web diverse alla volta. Vuoi acquisire a livello di codice informazioni specifiche dal World Wide Web per un'ulteriore elaborazione? Con DeepCrawl, puoi eseguire più attività alla volta e risparmiare un sacco di tempo ed energia. Questo strumento naviga le pagine web, estrae le informazioni utili e ti aiuta a indicizzare il tuo sito in modo corretto.

Come utilizzare DeepCrawl per indicizzare le pagine Web?

Passo 1: Comprendere la struttura del dominio:

Il primo passo è installare DeepCrawl. Prima di avviare la scansione, è anche utile capire la struttura del dominio del tuo sito Web. Vai a www / non-www o http / https del dominio quando aggiungi un dominio. Dovresti anche identificare se il sito web sta usando o meno un sottodominio.

Passo 2: Esegui la scansione per prova:

Tu può iniziare il processo con una piccola ricerca per indicizzazione web e cercare i possibili problemi sul tuo sito Web. Dovresti anche controllare se il sito web può essere sottoposto a scansione o no, per cui dovresti impostare il "Limite Scansione" alla quantità bassa. Renderà il primo controllo più efficiente e preciso e non dovrai aspettare ore per ottenere i risultati.Tutti gli URL che ritornano con codici di errore come 401 vengono negati automaticamente.

Passo 3: Aggiungere le restrizioni della scansione:

Nel passaggio successivo, è possibile ridurre la dimensione della scansione escludendo le pagine non necessarie. L'aggiunta di restrizioni garantirà o sprecare il tuo tempo nella scansione degli URL che non sono importanti o inutili. Per fare ciò, devi fare clic sul pulsante Rimuovi parametri in "Impostazioni avanzate e aggiungere URL non importanti. La funzione" Sovrascrivi robot "di DeepCrawl ci consente di identificare gli URL aggiuntivi che possono essere esclusi con un file robots.txt personalizzato, lasciando noi testiamo gli impatti che spingono nuovi file nell'ambiente live.

Puoi anche usare la sua funzione "Raggruppamento delle pagine" per indicizzare le tue pagine web ad alta velocità.

Passo 4: verifica i risultati:

Una volta che DeepCrawl ha indicizzato tutte le pagine Web, il passaggio successivo consiste nel verificare le modifiche e assicurarsi che la configurazione sia accurata. aumentare il "Limite di scansioni" prima di eseguire la ricerca per indicizzazione più approfondita.
