Semalt Expert décrit 10 façons de mettre en œuvre les outils de grattage Web

Le raclage du Web se fait de plusieurs façons, et il y a différents méthodes pour accomplir une tâche particulière. C'est un domaine avancé avec des développements actifs, des initiés ambitieux et des percées importantes dans les domaines de l'intelligence artificielle, de l'interaction homme-machine et du traitement de texte. Les outils de raclage web vont chercher, télécharger et extraire les données choisies, vous fournissant des formats souhaitables. Divers outils vous permettent de collecter des données de centaines à des milliers d'URL en quelques secondes. Voici quelques façons d'utiliser les outils de grattage Web.

1. Contenu et abonnés

Les blogs des concurrents et les profils de médias sociaux sont un bon endroit pour analyser le contenu. Peut-être, il ouvrira les portes pour vous d'utiliser les techniques de gratte-ciel et de construire la base de vos rivaux d'affaires. Vous pouvez également voir combien de followers ils ont et combien de personnes examinent et aiment leurs pages. Les données bien extraites peuvent vous aider à collecter des informations sur votre concurrent, à donner plus d'abonnés à votre marque sur les réseaux sociaux et à générer plus de trafic vers votre site Web.

2. Détection

Un bon grattoir aidera, détectera, grattera et obtiendra des informations de différentes pages Web. Nous pouvons facilement prendre le pouls de nos concurrents et avoir une idée de leurs produits, de leurs campagnes promotionnelles, de leurs blogs et de leurs stratégies marketing. Avec les données bien réduites, nous pouvons ajuster les stratégies de marketing de notre marque et ce changement profitera sûrement à notre entreprise.

3. Avis

Vous pouvez gratter des informations utiles de Yelp, Google, Trustpilot, TripAdvisor, Zomato, Amazon et Yahoo comme des entreprises géantes pour voir comment les clients les ai examinés. Tournez-vous vers les sites de médias sociaux et recherchez les marques ou les produits pour obtenir des données utiles. Cette information racolée peut être utilisée pour profiter des faiblesses, des plaintes et des problèmes du concurrent.

4. Comparaison des prix

Vous pouvez gratter les données pour les comparaisons de prix et le suivi. Il est important de savoir ce que vos concurrents facturent pour un produit particulier et combien de produits de la même série sont présents sur leurs sites Web. La comparaison des prix est importante pour les détaillants en ligne, et les données récupérées sont le seul moyen de comparer les prix de manière optimale..Par exemple, les chaînes d'épiceries (Sainsbury, Waitrose et Tesco) utilisent le grattage sur le Web comme une partie essentielle de leurs stratégies de tarification. Ils raclent plusieurs articles chaque jour et utilisent cette information pour comparer les prix de leurs différents produits.

5. Optimisation des moteurs de recherche

Le trafic entrant sur un site passe par différents canaux, tels que le trafic payant, le trafic sur les médias sociaux, les courriels, les renvois et autres. Pour beaucoup d'entre nous, c'est une recherche organique qui sert la grosse part du gâteau. Mais pour les autres, ce trafic ne signifie rien et ils se concentrent sur l'optimisation des moteurs de recherche plus que toute autre stratégie.

6. Étude de marché

Tous les hommes d'affaires savent que les études de marché constituent une partie essentielle de l'activité. Vous devriez vérifier les opportunités, les tendances et les menaces grâce à une étude de marché. Une fois que les données sont récupérées sur les sites des concurrents, toutes les informations sont obtenues facilement, et vous pouvez avoir une idée de la façon de développer votre entreprise avec une étude de marché appropriée. Les scrapers Web peuvent extraire les données nécessaires auprès des sociétés d'études de marché, des fournisseurs d'analyse, des annuaires en ligne, des sites d'informations et des blogs de l'industrie. Vous pouvez profiter de ces données et étendre votre réseau dans le monde entier.

7. Recherche d'emploi et recrutement

Si vous cherchez un nouvel emploi, vous devriez gratter des douzaines de sites d'emploi, de sites de médias sociaux et de forums. Vous pouvez également obtenir des informations utiles à partir des sites de bulletin numérique et des annonces classées. Et si vous recherchez des candidats appropriés pour votre organisation, vous pouvez vous tourner vers des données récupérées et filtrer les résultats en fonction de vos besoins. Quoi qu'il en soit, les outils de raclage web vous donneront des informations utiles sur ce qui se passe sur le marché du travail, comment embaucher les bons candidats et comment décrocher un emploi de rêve.

8. Produits et services

Nous achetons tous des produits et services sur Internet. En tant que client, nous pouvons copier et agréger les répertoires pour obtenir des données utiles. Nous pouvons également comparer les prix et les avis pour savoir quels produits et services sont les plus appropriés. Par exemple, vous pouvez compiler la liste des véhicules d'occasion correspondant à vos besoins sur une variété de sites. Alternativement, vous pouvez consulter les avis des différents smartphones pour avoir une idée de la marque qui domine les autres. Certains des choix les plus intelligents sont iPhone, Windows Mobile et BlackBerry.

9. Planification financière

Avec les outils de grattage Web, vous pouvez gratter les données des sites boursiers, sites Web de propriété, et vérifier les critiques de différents portails pour des gains financiers. Il vous sera facile de collecter les informations dont vous avez besoin pour rester informé des tendances marketing actuelles.

10. Vous cherchez à acheter ou à louer

Pour une meilleure idée de grattage Web, vous devriez envisager les agences immobilières. Si vous cherchez à acheter ou louer quelque chose, vous avez certainement besoin de gratter les données et avoir une idée de ce type de propriété vous conviendra le plus. En tant que chasseur de maisons, vous pouvez créer des ensembles de données bien organisés à partir de différents agents, listes, sites d'agrégation.
