A web crawler (also known as a crawling agent, a spider bot, web crawling software, website spider, or a search engine bot) is a tool that goes through websites and gathers information. In other words, the spider bot crawls through websites and search engines searching for information.
Web crawlers start from a list of known URLs and crawl these webpages first. After this, web crawlers find hyperlinks to other URLs, and the next step is to crawl them. As a result, this process can be endless. This is why web crawlers will follow particular rules. For example, what pages to crawl, when they should crawl these pages again to check for content updates, and much more.
