Expert van Semalt beschrijft 10 manieren om de webschrapingstools te implementeren

Webschrapen gebeurt op een aantal manieren en er zijn verschillende methoden om een bepaalde taak te volbrengen. Het is een geavanceerd veld met actieve ontwikkelingen, ambitieuze ingewijden en prominente doorbraken op het gebied van kunstmatige intelligentie, mens-computerinteractie en tekstverwerking. De tools voor webscraping halen, halen en extraheren de gekozen gegevens, en voorzien u van de gewenste formaten. Met verschillende hulpprogramma's kunt u binnen enkele seconden gegevens van honderden tot duizenden URL's verzamelen. Hier zijn enkele manieren om webschrapen te gebruiken.

1. Inhoud en volgers

De blogs en sociale-mediaprofielen van concurrenten zijn een goede plaats om inhoud te analyseren. Misschien opent het de deuren voor u om de wolkenkrabbertechnieken te gebruiken en het fundament van uw zakelijke rivalen af te bouwen. Je kunt ook zien hoeveel volgers ze hebben en hoeveel mensen hun pagina's beoordelen en leuk vinden. De goed opgehaalde gegevens kunnen u helpen informatie over uw concurrent te verzamelen, uw merk meer volgers op sociale media te geven en meer verkeer naar uw website te leiden.

2. Detectie

Een goede krabber zal helpen bij het opsporen, schrapen en verkrijgen van informatie van verschillende webpagina's. We kunnen gemakkelijk de vinger aan de pols houden van onze concurrenten en een idee krijgen van hun producten, promotiecampagnes, blogposts en marketingstrategieën. Met de goed geschaalde gegevens kunnen we de marketingstrategieën van ons merk aanpassen en deze verandering zal onze onderneming zeker ten goede komen.

3. Recensies

U kunt nuttige informatie van Yelp, Google, Trustpilot, TripAdvisor, Zomato, Amazon en Yahoo als gigantische bedrijven schrapen om te zien hoe klanten heb ze beoordeeld. Ga naar de sociale-mediasites en doorzoek de merken of producten om nuttige gegevens te verkrijgen. Deze geschaalde informatie kan worden gebruikt om te profiteren van de zwakke punten, klachten en problemen van de concurrent.

4. Prijsvergelijking

U kunt gegevens schrappen voor prijsvergelijkingen en tracking. Het is belangrijk om te weten wat uw concurrenten aanrekenen voor een bepaald product en hoeveel producten van dezelfde serie op hun websites aanwezig zijn. Prijsvergelijking is belangrijk voor online retailers, en geschraapte data is de enige manier om prijzen op een betere manier te vergelijken..Bijvoorbeeld, supermarktketens (Sainsbury, Waitrose en Tesco) gebruiken webschrapen als een must onderdeel van hun prijsstrategieën. Ze schrapen elke dag meerdere items en gebruiken deze informatie om de prijzen van hun verschillende producten te vergelijken.

5. Search Engine Optimization

Het verkeer dat naar een site komt, komt via verschillende kanalen aan, zoals betaald verkeer, verkeer via sociale media, e-mails, verwijzingen en andere. Voor velen van ons is het een organische zoektocht die het grootste deel van de taart serveert. Maar voor anderen betekent dit verkeer niets en concentreren ze zich meer op zoekmachineoptimalisatie dan op enige andere strategie.

6. Marktonderzoek

Alle ondernemers weten dat marktonderzoek een essentieel onderdeel van het bedrijf is. Je zou via marktonderzoek de kansen, trends en bedreigingen moeten controleren. Zodra de gegevens van de sites van concurrenten zijn geschraapt, wordt alle informatie gemakkelijk verkregen en kunt u een idee krijgen van hoe u uw bedrijf kunt laten groeien met goed marktonderzoek. De webschrapers kunnen de nodige gegevens extraheren van de marktonderzoeksbureaus, analytische aanbieders, onlinegidsen, nieuwswebsites en brancheblogs. U kunt profiteren van deze gegevens en uw netwerk wereldwijd uitbreiden.

7. Jagen en werven van banen

Als u op zoek bent naar een nieuwe baan, moet u tientallen vacaturesites, sociale-mediasites en forums schrapen. U kunt ook nuttige informatie krijgen van de websites met digitale bulletins en gerubriceerde vermeldingen. En als u op zoek bent naar geschikte kandidaten voor uw organisatie, kunt u zich wenden tot geschaalde gegevens en de resultaten filteren op basis van uw vereisten. Hoe dan ook, met de webschrapingtools krijgt u nuttige informatie over wat er gaande is op de arbeidsmarkt, hoe u de juiste kandidaten kunt aannemen en hoe u een droomjob kunt doen.

8. Producten en diensten

Ieder van ons koopt producten en diensten op internet. Als klant kunnen we de mappen kopiëren en aggregeren om bruikbare gegevens te verkrijgen. We kunnen ook de prijzen en beoordelingen vergelijken om te weten welke producten en services het meest geschikt zijn. U kunt bijvoorbeeld de lijst met gebruikte voertuigen die aan uw vereisten voldoen, op verschillende websites samenstellen. U kunt ook de beoordelingen van verschillende smartphones bekijken om een idee te hebben van welk merk de andere domineert. Enkele van de slimste keuzes zijn iPhone, Windows Mobile en BlackBerry.

9. Financiële planning

Met de webschrapingtools kunt u gegevens van beurssites, vastgoedwebsites schrapen en de beoordelingen van verschillende portals bekijken voor financiële winst. U kunt gemakkelijk gegevens verzamelen die u nodig hebt om op de hoogte te blijven van de huidige marketingtrends.

10. Op zoek om te kopen of te huren

Voor een beter idee van webschrapen moet u rekening houden met de makelaars. Als u iets wilt kopen of huren, moet u zeker gegevens schrapen en een idee hebben van welk type woning het meest geschikt voor u is. Als woningzoekende kunt u overzichtelijke gegevenssets maken van verschillende agenten, lijsten, aggregatiesites.
