Semalt Expert - Wat is webschrapen?

Gegevensschrapen (of webschrapen) is de techniek waarbij uw computer programma of tool haalt nuttige gegevens uit uw blog of site zodat deze offline kunnen worden gebruikt, voor andere doeleinden. Voor verschillende mensen klinkt schavijwerk een beetje intimiderend, maar de schraapgereedschappen verwerken elke dag een groot aantal sites en kunnen u helpen om binnen een mum van tijd nuttige gegevens van bepaalde webpagina's vast te leggen. Het duurt slechts enkele seconden om een webschrapingstool te gebruiken om de webpagina's te identificeren, herkennen en organiseren en om met de enorme databases om te gaan. Maar er zijn enkele specifieke manieren om ervoor te zorgen dat u optimaal gebruikmaakt van uw webschrapen. Met deze methoden kunt u probleemloos omgaan met webpagina's, teksten, afbeeldingen, grafische afbeeldingen, memes en infographics en kunt u al die dingen gemakkelijk opslaan op uw computer.

Search Engine Optimization (SEO):

Het verkeer dat naar een site of blog komt, kan afkomstig zijn van een aantal kanalen, zoals direct en organisch verkeer , betaald verkeer, sociale media, doorverwijzing en e-mails. Het is belangrijk om de prestaties van uw site met SEO te verbeteren en het bouncepercentage enigszins te verminderen..Wanneer u uw site scrapt met een webschrapingstool, kunt u de bestanden controleren of doornemen die relevant zijn voor uw online bedrijf. Op deze manier kun je de belangrijke dingen op één plek organiseren en de onbelangrijke dingen op een andere plek. Bovendien helpt het de zoekmachineoptimalisatie van uw site te verbeteren, omdat de inhoud nuttig is en veel zinvolle zoekwoorden bevat.

Marktonderzoek:

Alle ondernemers weten dat marktonderzoek een integraal onderdeel is van hun succes. Als u op het punt staat uw bedrijf te starten, te veranderen of uit te breiden, moet u goed marktonderzoek doen naar de beste webschrapingtools, zodat u zowel waardevolle als niet-waardevolle inhoud kunt organiseren volgens de vereisten van uw klanten. Met andere woorden, we kunnen zeggen dat er een sterke relatie bestaat tussen marktonderzoek en effectieve webschrapingstools, omdat beide naast elkaar zullen werken voor uw bedrijfsgroei.

Leadgeneratie:

Net als marktonderzoek is het genereren van leads belangrijk om een bedrijf op internet te laten groeien. Afhankelijk van uw merk, kunnen de leads u nuttigere gegevens en contactgegevens van de potentiële klanten opleveren. Verschillende webscraping-programma's kunnen u helpen bij het organiseren van uw inhoud en een idee krijgen van welke soorten leads moeten worden gegenereerd voor een succesvolle en vruchtbare onderneming op internet.

Recensies en sentiment:

Je zou liever scrapen van Yelp, TripAdvisor, Zomato, Google, Trustpilot, Amazon, het Better Business Bureau en andere zakelijke besprekingen sites om een idee te krijgen of uw klanten tevreden zijn met uw producten en diensten of niet. Hiervoor moet je je wenden tot sociale-mediasites en de merken en producten zoeken op namen om een idee te hebben van wat voor soort gegevens ze op internet hebben gescrapt. De bijbehorende beoordelingen en zakelijke profielen schrapen geven u inzicht in hoe u verder kunt gaan met uw bedrijf. Het geeft je ook informatie over de zwakke punten en sterke punten van de concurrent, zodat je maatregelen kunt nemen om je naamsbekendheid te vergroten.
