by
Dec 04, 2017

L'exploration Web consiste à cibler les données nouvelles et existantes d'un site Web et à les stocker dans les bases de données des moteurs de recherche pour un accès facile. Il est vrai que les outils du robot d'indexation Web gagnent en popularité avec le temps car un robot d'indexation Web a automatisé et simplifié toute la procédure d'analyse pour rendre les ressources de données Web accessibles à tous les utilisateurs sur Internet. Certains outils de moteur de balayage Web permettent aux utilisateurs d'indexer ou d'explorer leurs sites ou leurs blogs de manière méthodique et efficace sans avoir besoin de codes. Ils transforment également les données en différents formats et se conforment aux exigences des utilisateurs.

Ici, nous avons discuté d'excellents outils de robot Web pour gratter les sites Web et les blogs.

1. Cyotek WebCopy

Cyotek WebCopy est un robot d'exploration de site complet et gratuit qui vous permet de copier le site partiel ou entier localement sur votre disque dur pour le lire lorsqu'il n'y a pas d'Internet connexion. Ce programme analyse les sites Web spécifiés avant de télécharger ses données ou son contenu sur votre disque dur spécifique. Il automatise également les liens vers les ressources telles que les images, les pages Web et le contenu local d'un site, et exclut les sections du même site Web qui ne signifient rien pour les moteurs de recherche.

2. HTTrack

C'est un outil exceptionnel et l'un des meilleurs outils de robot Web pour gratter vos sites Web.HTTrack est un programme gratuit qui fournit différentes fonctions et options adaptées pour télécharger le site entier d'Internet à votre ordinateur ou appareil mobile. Certaines de ses célèbres versions sont Windows, Sun Solaris, Unix et Linux. Ce programme aide à refléter votre site plus d'une fois et aide la procédure d'exploration Web plus facilement et plus rapidement. Vous pouvez également accéder aux images, fichiers, codes HTML, répertoires et interrompre le téléchargement à tout moment et en tout lieu.

3. Octoparse

Octoparse est un crawler web puissant et gratuit qui est utilisé pour extraire toutes sortes de données de votre site. Ce programme utilise quelques options pour améliorer votre site web et dispose de nombreuses fonctionnalités pour en tirer profit. Ses deux modes célèbres sont le mode avancé et le mode assistant, qui sont bons pour les programmeurs pour s'habituer à Octoparse en un rien de temps. Vous pouvez télécharger votre site en quelques secondes grâce à cet outil complet. De plus, vous pouvez enregistrer le site dans différents formats bien structurés tels qu'Excel, HTML et texte.

4. Getleft

Getleft est un programme facile à utiliser qui permet de gratter un blog ou un site instantanément. Il va télécharger l'intégralité de votre site et dispose de plusieurs options pour en bénéficier. Vous pouvez également entrer l'URL et sélectionner les fichiers que vous souhaitez télécharger sur votre ordinateur. Ce programme est l'un des meilleurs car il est disponible en 15 langues différentes, avec un support 24/7, et rend votre expérience de navigation merveilleuse et exceptionnelle.

5. Scraper

Le Scraper est une célèbre extension Chrome qui possède des propriétés d'extraction de données limitées, mais qui facilite la recherche en ligne. Il exporte également vos données vers Google Spreadsheets plutôt que votre propre ordinateur, ce qui vous fait gagner beaucoup de temps. Scraper peut être intégré à votre navigateur Web et générera de petits chemins pour définir votre URL pour les moteurs de recherche.
