A web crawler, also known as a web spider, spider bot, or simply crawler, is an automated software program that systematically browses the World Wide Web to collect information and index web pages. Web crawlers play a crucial role in search engine operations by gathering and organizing content from across the internet. They follow links from one web page to another, discovering and indexing new pages, and updating information about existing pages.
Web crawlers operate on a set of algorithms and follow certain rules, such as the frequency of visits to a particular website, the number of pages to crawl, and the type of content to index. They also respect the robots.txt file, which webmasters use to communicate with crawlers, and provide guidelines about which parts of their websites should or shouldn’t be crawled.
Crawled data is then processed and analyzed by search engines to rank and display relevant search results for users. In addition to search engines, web crawlers can be used for a variety of purposes, such as data mining, website maintenance, monitoring website updates, and more.
The data collected by this spider is publicly accessible and searchable for no charge. Please send us an email for more information.
