The primary use of web scraping in data analysis is to extract vast amounts of information from websites and utilize it for various analytical purposes. Businesses often scrape data for market research, competitive analysis, and sentiment analysis by gathering relevant information in real time. This technique enables companies to analyze trends, gather insights on customer preferences, and monitor competitors' activities. By utilizing web scraping, organizations can uncover valuable data insights that might otherwise remain untapped, driving strategic decision-making and optimizing overall performance.
