What is the main process of a Web crawler program?

Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. Crawlers consume resources on visited systems and often visit sites unprompted. Issues of schedule, load, and “politeness” come into play when large collections of pages are accessed.
