Definition - What does Web Scraping mean?

Web scraping is a term for various methods used to collect information from across the Internet.

Those who use web scraping programs may be looking to collect certain data to sell to other users, or to to use for promotional purposes on a website.

Techopedia explains Web Scraping

Web scraping is essentially a form of data mining. Items like weather reports, auction details, market pricing, or any other list of collected data can be sought in Web scraping efforts.

The practice of Web scraping has drawn a lot of controversy because the terms of use for some websites do not allow certain kinds of data mining. Despite the legal challenges, Web scraping promises to become a popular way of collecting information as these kinds of aggregated data resources become more capable.
