![]() Web scraping is a simple concept, really requiring only two elements to work: A web crawler and a web scraper. It's a hands-off and extremely powerful means of collecting data for a number of applications. Unlike the monotonous process of manual data extraction, which requires a lot of copy and pasting, web scrapers use intelligent automation, allowing you to send scrapers out to retrieve endless amounts of data from across the web. If you've ever copied and pasted a piece of text that you found online, that's an example (albeit, a manual one) of how web scrapers function. You may also know web scraping by another name, like "web data extraction," but the goal is always the same: It helps people and businesses collect and make use of the near-endless data that exists publicly on the web.
