Understanding the Problem

What is a Web Crawler?

📦Product definition
A web crawler is a system that systematically discovers and downloads web pages across the internet, starting from a set of seed URLs and following hyperlinks to find new pages.

Think of it as an automated reader that never sleeps. You give it a handful of starting URLs, it fetches those pages, pulls out every link it finds, and adds those links to its to-do list. Then it repeats. Billions of times.
