Semalt legt uit welke vaardigheden je nodig hebt om webschrapen onder de knie te krijgen

by
Dec 08, 2017

Als u op zoek bent naar gegevens om uw online bedrijf van brandstof te voorzien, kan het het is niet mogelijk voor u om gegevens te verzamelen door gewoon op Google te zoeken. Soms moeten we een paar webcrawlers en dataschrapers gebruiken om onze projecten gedaan te krijgen, en soms moeten we basisvaardigheden ontwikkelen. Het klopt dat de zoekmachines u kunnen helpen vinden wat u zocht, maar u moet de volgende vaardigheden ontwikkelen om te slagen.

1. De mogelijkheid om het robots.txt-bestand te lezen

U moet de robots.txt-bestanden correct kunnen lezen en bewerken. Dit bestand wordt gebruikt om te voorkomen dat de crawlers uw site te vaak bezoeken. Tegelijkertijd helpt het u de kwaliteit van uw gekraste gegevens te behouden en de snelheid van uw website voor menselijke bezoekers te verbeteren. Daarom moet u leren hoe u het robots.txt-bestand bewerkt. Als je dit bestand goed hebt bewerkt, kun je slechte bots verwijderen die niet voldoen aan de regels en voorschriften van zoekmachines. Bovendien kunt u verschillende webpagina's tegelijkertijd targeten en gemakkelijk de gewenste gegevens schrapen of extraheren.

2. De gegevensinfrastructuur instellen

Het is zeer belangrijk om de gegevensinfrastructuur in te stellen, omdat hiermee kwaliteitsgegevens van de hele website worden ontgrendeld.U moet bijvoorbeeld SQL, PHP en andere soortgelijke talen leren om de infrastructuur van uw gegevens op een betere manier te onderhouden. Door de gegevensinfrastructuur in te stellen, kunt u een self-service analist worden en krijgt u binnen een paar minuten meer accurate en goed geschaalde gegevens.

3. Basisideeën van HTML, CSS en JavaScript

Het is belangrijk om HTML, JavaScript en CSS te leren als u de hele website wilt schaven zonder concessies te doen aan de kwaliteit. Als u zich afvraagt hoe programmeurs werken en niets heeft gedaan om uw webinhoud te schrapen, is het tijd om wat te leren programmeer talen en ontwikkel een paar vaardigheden. Aan iemand die nog nooit eerder had gecodeerd, zullen de concepten van HTML, JavaScript en CSS b e relatief nieuw. Mogelijk moet u de gegevens steeds opnieuw schrapen totdat de kwaliteitsresultaten niet zijn behaald. Het is een gecompliceerd proces, maar als je eenmaal kennis hebt gemaakt met deze dingen, kun je zoveel webpagina's schrapen als je wilt zonder een tool voor het verwijderen van gegevens nodig te hebben. HTML en CSS zijn geen technische programmeertalen, dus ze zijn gemakkelijk te leren en je kunt ze binnen een paar dagen vasthouden.

4. Mogelijkheid om de bots te schrijven en te schalen

Je zou in staat moeten zijn om de goede bots en slechte bots te onderscheiden. De goede bots helpen bij het crawlen van uw website in de zoekresultaten van zoekmachines, waardoor u goed gestructureerde en hoogwaardige gegevens krijgt. Aan de andere kant zijn de slechte bots schadelijk voor uw site en krijgt u nooit goed geschaalde gegevens. Je moet niet alleen onderscheid maken tussen goede bots en slechte bots, maar je moet ook de bots schrijven en schalen. Je moet in gedachten houden dat bots de volgende stap zijn in de evolutie van computer en menselijke interactie. Het betekent dat hoe meer je weet over bots en schrijf ze regelmatig, hoe groter je kans wordt om kwaliteitsgegevens te schrapen en te profiteren van je bedrijf.
