The main purpose of a web crawler program is to automate the process of discovering and storing web pages.
Search engines use them to keep their databases updated. Without crawlers, Google wouldn’t know what’s new or changed online.
Fun fact: They’re also called "spiders" because they crawl through links like a spiderweb.
