Webspider
A web spider, also known as a web crawler, is an automated program or script used to systematically and automatically search the Internet. The purpose of a Web spider is to collect information from Web sites, such as text, images, links and other relevant data. Web spiders are often used by search engines such as Google, Bing and Yahoo to index Web pages to enable users to find information on the Internet quickly and efficiently.
The modus operandi of a web spider
A web spider usually starts at a particular home page or website and then follows the hyperlinks on that page to discover other pages. On each new page, the web spider looks for more links to follow and more information to gather. This process is performed repeatedly until the web spider has searched a significant portion of the Internet or until it is stopped or restricted by certain rules. Web spiders play a crucial role in tracking and indexing Internet content for search engines, allowing users to quickly and accurately find relevant information when they perform searches.
