Web Scraping

What is Web Scraping?
Web scraping is the automated collection of publicly available data from websites at scale. A scraper requests web pages the same way a browser does, then extracts specific fields — prices, product titles, reviews, availability — and stores them in a structured format such as JSON or CSV for analysis.

Modern web scraping combines several techniques: HTTP clients for simple pages, headless browsers for JavaScript-rendered content, proxy networks to distribute requests, and parsers that survive site redesigns. The output powers use cases from competitor price monitoring and digital shelf analytics to market research and training data for AI models.

Web scraping of public data is generally lawful when done responsibly — respecting site stability, avoiding personal data, and complying with applicable regulations — and it underpins much of the commercial data economy, including price comparison and travel-fare aggregation.
