Before seeking the answer of why, let’s first know what web scrapping is. It determines the act of peeling off the authentic content of a website. It is pretty much equal to copying & pasting. So is done to re-locate it while combining with other data at another web place.
However, the extract is modified a little bit but business rivalry instigates a few competitors to steal the most popular content. Thereby, such evil practitioners ensure commercial advantages. But it features only the evil aspect of the web scraping. There is another face of it that is valid and meaningful.
Netizens are multiplying by leaps and bounds. Web-browsing is no more a restricted zone for the professionals. Programmers have extended it a layman today. So technically, it is the need of the hour to scrap the web content for enriching it by adding more values.
How scrapping occurs?
The modern scraping tools & techniques are highly advanced and premium. Today, ScraperWiki, Web Scraper, Import.io, Kimono and many more software/applications are auto-scrapers. With a little bit of manual commands, the extract is all of the users. These have empowered a layman to extract & tailor the web content.
What actually the programmers do is creating & handling the trickiest coding. They employ Unix grep command or substitute techniques. They, also, use socket programming for summoning HTTP (URL) and analyzing the query languages for processing.

Likewise, the best web scrapping services help in fetching the directed information in the coding. It can be any promotional SMS, price, urls, email ids, offers or any other information. In the pan processing, API emerges elemental. It determines how software components should interact with each other.
However, all extractors’ processing differs as per requirements. But fundamentally, peeling off data is done through the aforementioned processing.
