5 Ways to Crawl a Website

From Wikipedia

A Web crawler, sometimes called a spider, is an Internet bot that systematically browses the World Wide Web, typically for the purpose of Web indexing .

A Web crawler starts with a list of URLs to visit, called the seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds them to the list of URLs to visit.  If the crawler is performing archiving of websites it copies and saves the information as it goes. The archive is known as the repository and is designed to store and manage the collection of web pages. A repository is similar to any other system that stores data, like a modern day database.
