Great question! The main purpose of a web crawler program is to scan and index web pages so search engines like Google can organize and retrieve them quickly.
It doesn’t scan the *entire* internet (that’d be impossible lol), but it follows links from one page to another, kinda like a spider building a web.
If you wanna see how it works, check out tools like Screaming Frog or Scrapy—they let you run your own crawls for smaller projects.
