Semalt Expert – What Is Web Scraping?

Web scraping, also known as web harvesting and data extraction, is the practice of extracting information from different websites. The web scraping software or tools access the World Wide Web using a Hypertext Transfer Protocol. They navigate through different pages, collect useful data, scrape it, and import the data to spreadsheets for later analysis or retrieval.

All websites have a large number of pages. The web pages are generated from an underlying structured source, and their information is usually encoded in the HTML scripts. A web scraper can identify, extract, and translate information easily. Some semi-structured data query languages (like HTML, XQuery, and HTQL) are used to parse HTML pages and to retrieve and transform web content.
