Web Crawler

A web page crawler is an automated program or script used to systematically search the World Wide Web and extract information from web pages. Usually, the crawling starts at a specific starting URL and follows links to other web pages to find and visit more URLs. While crawling, the crawler extracts various information such as text content, images, and links to other pages.

This information is stored in a database and can be used for various purposes such as creating search engine indexes, monitoring online information, or scraping data for scientific or commercial purposes.

Website crawlers are of great importance for search engine operators, researchers, market researchers and data analysts to collect information from websites. There are both publicly available and proprietary web crawlers that can be used for various purposes. It is important to note that crawling of web pages is only allowed if it is done in accordance with legal requirements and the policies of the web pages in question.
