Scraping
Scraping is the automated technique of collecting and extracting data from websites in a structured format using software tools or bots.
Definition
Scraping refers to the process of programmatically accessing web pages and extracting specific information such as text, prices, images, or metadata from their underlying HTML or rendered content. The extracted data is then converted into structured formats like databases, spreadsheets, or APIs for further use. In modern data ecosystems, scraping is often used alongside crawling and automation systems to gather high-volume, real-time web data for analysis, monitoring, and decision-making. It is widely applied in areas such as pricing intelligence, competitor tracking, and digital market research, especially in web scraping and anti-bot environments where scalability and accuracy are critical.
