Semalt: Quels sont les meilleurs Web Scrapers en ligne?

Dec 04, 2017

Le scraping des données 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 de grattage 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 d'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 programme de grattage de données complet et gratuit qui vous permet de copier un site sur votre disque dur de sorte que vous puissiez le lire sans connexion Internet. Ce programme analyse les sites Web spécifiés avant de télécharger leurs données ou contenu sur votre disque dur. 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

HTTrack est un programme gratuit qui offre différentes fonctions et options adaptées au téléchargement d'un site entier depuis Internet vers votre ordinateur ou appareil mobile. Certaines de ses célèbres versions sont Windows, Sun Solaris, Unix et Linux. Ce programme permet de refléter votre site plus d'une fois et rend la procédure d'exploration Web plus facile et plus rapide. Vous pouvez également accéder aux images, fichiers, codes HTML, répertoires et interrompre le téléchargement à tout moment.

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 possède 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 des sites dans différents formats bien structurés tels qu'Excel, HTML et texte.

4. Getleft

Getleft est un programme facile à utiliser qui permet de déchirer 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

Scraper est une célèbre extension Chrome qui a des propriétés d'extraction de données limitées, mais qui est utile pour effectuer des recherches en ligne. Il exporte également vos données vers Google Spreadsheets plutôt que votre propre ordinateur, ce qui vous fait gagner beaucoup de temps.
