How does a crawler work?
12/05/2022 | By: FDS
A crawler is a program that navigates the World Wide Web. It follows links to other pages and downloads their content to analyze it. Thus, it collects information about the structure of the web and stores it in a database. For example, it can collect all available links or all words on the page. Afterwards, this database can be used for different purposes, e.g. for search engines, for price comparisons or for scientific research.
