Web Scraping: Bots bons et mauvais - Explication Semalt

Les robots représentent près de 55% du trafic web. Cela signifie que la majeure partie du trafic de votre site Web provient des robots Internet plutôt que des êtres humains. Un robot est l'application logicielle responsable de l'exécution de tâches automatisées dans le monde numérique. Les robots effectuent généralement des tâches répétitives à grande vitesse et sont généralement indésirables pour les êtres humains. Ils sont responsables de petits travaux que nous tenons généralement pour acquis, y compris l'indexation des moteurs de recherche, la surveillance de l'état de santé du site Web, la mesure de sa vitesse, l'alimentation des API et la récupération du contenu Web. Les bots sont également utilisés pour automatiser l'audit de sécurité et analyser vos sites pour trouver des vulnérabilités, les corrigeant instantanément.

Explorer la différence entre les bons et les mauvais robots:

Les robots peuvent être divisés en deux catégories différentes, les bons robots et les mauvais robots. De bons robots visitent vos sites et aident les moteurs de recherche à explorer différentes pages Web. Par exemple, Googlebot explore de nombreux sites Web dans les résultats Google et permet de découvrir de nouvelles pages Web sur Internet. Il utilise des algorithmes pour évaluer quels blogs ou sites Web doivent être explorés, à quelle fréquence l'exploration doit être effectuée et combien de pages ont été indexées jusqu'à présent. Les bad bots sont responsables de l'exécution de tâches malveillantes, y compris le raclage de sites Web, le spam de commentaire  et les attaques DDoS..Ils représentent plus de 30% de tout le trafic sur Internet. Les pirates informatiques exécutent les mauvais robots et exécutent une variété de tâches malveillantes. Ils scannent des millions à des milliards de pages Web et visent à voler ou gratter le contenu illégalement. Ils consomment également la bande passante et recherchent continuellement des plugins et des logiciels qui peuvent être utilisés pour pénétrer vos sites Web et vos bases de données. 

Quel est le mal?

Habituellement, les moteurs de recherche considèrent le contenu raclé comme le contenu dupliqué. Il est dangereux pour vos classements de moteur de recherche et les éraflures saisiront vos flux RSS pour accéder et republier votre contenu. Ils gagnent beaucoup d'argent avec cette technique. Malheureusement, les moteurs de recherche n'ont mis en place aucun moyen de se débarrasser des mauvais robots. Cela signifie que si votre contenu est copié et collé régulièrement, le classement de votre site sera endommagé dans quelques semaines. Les moteurs de recherche pénalisent les sites qui contiennent du contenu en double, et ils ne peuvent pas reconnaître quel site Web a d'abord publié un contenu.

Tous les raclages sur le web ne sont pas mauvais

Nous devons admettre que le raclage n'est pas toujours nocif et malveillant. Il est utile pour les propriétaires de sites Web quand ils veulent propager les données à autant de personnes que possible. Par exemple, les sites gouvernementaux et les portails de voyages fournissent des données utiles au grand public. Ce type de données est généralement disponible sur les API, et des scrapers sont utilisés pour collecter ces données. En aucun cas, il est dangereux pour votre site Web. Même lorsque vous grattez ce contenu, cela ne nuira pas à la réputation de votre entreprise en ligne.

Un autre exemple de raclage authentique et légitime est constitué par les sites de regroupement tels que les portails de réservation d'hôtels, les sites de billetterie et les médias. Les robots qui sont responsables de la distribution du contenu de ces pages Web obtiennent des données via les API et les récupèrent selon vos instructions. Ils visent à générer du trafic et à extraire des informations pour les webmasters et les programmeurs.
