Veebikraapereid, known in English as web scrapers or web crawlers, are software programs designed to automate the process of extracting data from websites. These tools systematically browse the internet, typically following links from one page to another, to collect specific information. The data gathered can range from product prices and customer reviews on e-commerce sites to news articles, contact details, or even the structure of a website itself.

The functionality of web scrapers can vary widely, from simple scripts that download the content of a single page to complex systems that can navigate dynamic websites, handle logins, and extract data in structured formats like CSV or JSON. They are essential for many applications, including market research, price comparison, lead generation, data analysis, and the development of search engines.

However, the use of web scrapers also raises ethical and legal considerations. Website owners may implement measures to block scraping, such as CAPTCHAs or IP address restrictions, to protect their data and resources. Unauthorized scraping can sometimes violate a website's terms of service, and in certain jurisdictions, it may have legal implications, particularly if proprietary or personal data is involved. Responsible web scraping involves respecting robots.txt files, avoiding overwhelming website servers, and adhering to legal and ethical guidelines.
