Web scraping services create a process for automated data extraction using web scrapers. Web scraping service providers such as ScrapeHero, specialize in creating web scrapers designed to scrape websites without getting detected and have the ability to easily scale scraping a few hundred pages to millions of pages of data.
Web scraping is used to extract or “scrape” data from any web page on the Internet.
Copying a list of contacts from a web directory is an example of “web scraping”. But copying and pasting details from a web page into an Excel spreadsheet works for only a small amount of data and it requires a significant amount of time. Web scraping takes the pain out of this experience by automating the whole process.
Web scraping is performed using a “web scraper” or a “bot” or a “web spider” or “web crawler” (words used interchangeably). A web-scraper is a program that goes to web pages, downloads the contents, extracts data out of the contents, and then saves the data to a file or a database.

How Does a Web Scraper Work
Below are the steps a web scraper follows to extract data from a website:
It all starts at the data source and deciding which data fields we need to extract. Once we have a clear understanding of the requirement we can start building a crawler to find the data in the website. These web crawlers, crawl the website and visit the links that we want to extract data from.
2. Data Scraping
In this step, we extract and parse the meaningful data elements from the raw scraped data that is in HTML format. In some cases extracting data may be simple such as getting the product details, job or business listings from a web page or something complex like filling a form to extract specific information.
3. Data Formatting
The data extracted using a parser won’t always be in the format that is suitable for immediate use. Most of the extracted datasets need some form of “cleaning” or “transformation”. Hence the data extracted needs to be formatted into a human-readable form such as CSV, JSON, or XML.

Depending on your requirement and expertise level you can choose any one of the following web scraping methods to get started:

Is Web Scraping Legal
Although web scraping is a powerful technique in collecting large data sets, it is controversial and may raise legal questions related to copyright and terms of service. Most times a web scraper is free to copy a piece of data from a web page without any copyright infringement. This is because it is difficult to prove copyright over such data since only a specific arrangement or a particular selection of the data is legally protected.
Legality is totally dependent on the legal jurisdiction (i.e. Laws are country and locality specific). Publicly available information gathering or scraping is not illegal, if it were illegal, Google would not exist as a company because they scrape data from every website in the world.
