Web Scraping Tips van Semalt

Jan 22, 2018

Node.js is een open-sourceomgeving voor het uitvoeren van JavaScript-codes. PayPal, LinkedIn, Microsoft, GoDaddy, Yahoo, IBM en Cisco Systems zijn de bekendste zakelijke gebruikers. In de afgelopen maanden zijn een aantal op Node gebaseerde datatextractors geïntroduceerd, maar de meest bekende is Product Scraper.

Productschraper is geschikt voor e-commerce websites en schraapt informatie van BestBuy, Walmart, eBay, Target en Amazon-achtige websites. Deze tool biedt ons accurate informatie over een product, waaronder de titel, beschrijving, afbeelding en prijs. Bovendien heeft Product scraper een eenvoudig te gebruiken API en kan gemakkelijk met elke webbrowser worden geïntegreerd.

Productschraper als geschikte tool voor het extraheren van gegevens:

Als u onlangs een e-commerce website heeft opgezet, wilt u misschien informatie verzamelen over uw concurrenten en leveranciers, hun producten, prijzen en afbeeldingen. U kunt eenvoudig verschillende e-commercesites zoals Amazon, Walmart en eBay vergelijken en nuttige informatie verkrijgen met behulp van Product Scraper. Deze tool is uniek omdat het helpt verschillende e-commercesites te vergelijken, hun productlijsten, afbeeldingen, recensies en prijsinformatie te verkrijgen. In tegenstelling tot andere standaardtools verkrijgt productschraper de gegevens door verschillende webpagina's online te doorzoeken en te vergelijken en krijgt u informatie over verkopers en leveranciers. We kunnen dus stellen dat Product Scraper de ruggengraat is van e-commerce websites.

Gebruik een productkrabber om de prijzen en diensten van concurrenten te volgen:

Verschillende producten online tegen concurrerende prijzen verkopen, was altijd een uitdaging voor ons allemaal. Soms raken gebruikers in de war over de fluctuerende prijzen van verschillende producten op internet. Amazon en eBay proberen de prijzen op een goed niveau te houden en willen steeds meer klanten aantrekken. Voor het opstarten is het verkrijgen van productinformatie erg belangrijk. Met Product Scraper kunt u eenvoudig de prijzen van verschillende producten vergelijken en uw website op een betere manier optimaliseren. Als u bijvoorbeeld gegevens van reisportals of e-commercebedrijven wilt extraheren, moet u Product scraper onmiddellijk proberen. Deze tool verzamelt, organiseert en extraheert gegevens voor u in realtime.

Productschraper gebruiken om de markttendensen te evalueren:

De e-commercesites en onlineactiviteiten houden hun tegenhangers regelmatig in het oog. Amazon houdt bijvoorbeeld de huidige markttendensen in de gaten en verzamelt informatie over producten en diensten van BestBuy en Walmart. Bovendien vergelijkt het hun prijzen en producten met een eigen assortiment. Met productschraper krijgt u dezelfde informatie. Met deze tool krijgt u bruikbare inzichten en krijgt u goed opgehaalde gegevens voor uw bedrijf. Afgezien daarvan geeft het informatie over hoe uw concurrenten hun producten verzenden en welk type korting online wordt aangeboden.

Productschraper haalt nauwkeurige informatie over leveranciers:

E-commerce websites en marktplaatsen hebben honderden actieve leveranciers. Met Product Scraper kunt u informatie verzamelen over tal van leveranciers en hun producten en prijzen vergelijken. Je kunt ook gegevens ophalen van Amazon en eBay en je webpagina's dienovereenkomstig crawlen. Webontwikkelaars en programmeurs kunnen schaalbare servers met productschraper maken en kunnen een aantal taken gemakkelijk uitvoeren.
