What is Web Scraping?

Web scraping is the automated process of collecting data from websites. By using specialized software or scripts, businesses and developers can extract vast amounts of information quickly and efficiently. This data can be used for various purposes, including market research, competitive analysis, and content aggregation.

How Does Web Scraping Work?

At its core, web scraping involves fetching a web page, parsing the HTML or XML content, and extracting relevant data. The process typically includes the following steps:

1. Sending an HTTP Request: The scraper sends a request to the server hosting the target website.
2. Retrieving the HTML Content: The server responds by sending back the HTML content of the requested page.
3. Parsing the Data: The scraper processes the HTML to extract the desired information.
4. Storing the Data: Finally, the extracted data is saved in a structured format for analysis or further use.

Web scrapers are becoming increasingly sophisticated, utilizing advanced techniques to bypass common web security measures.
