Crawler

What is a Crawler?

A crawler, also known as a spider or bot, is a software program that navigates the web and extracts information from websites to store these details in an index, as done by search engines like Google.

How Does a Crawler Work?

Crawlers automatically visit web pages and follow the links on those pages to other sites. They collect data about the pages, such as texts, images, and links, and use this data to create an index, which forms the basis for a search engine's search results.
