Yo, great question! A crawler in the tech world is basically a bot that scans the web by following links. It starts with a seed URL (like Google’s homepage) and then hops from one page to another, kinda like a spider building a web.
It doesn’t just grab everything—search engines use algorithms to prioritize important or fresh content. Tools like Screaming Frog or Scrapy let you see how crawlers work firsthand.
And yeah, they avoid infinite loops by tracking visited URLs and respecting robots.txt files. Wild stuff!
