Reverse web-link graph

Definition

A reverse web-link graph is a representation of web pages where each page is a node and directed edges point from a page to all the pages that link to it. This structure is useful in analyzing the relationships and connections between different web pages, especially in the context of algorithms for web crawling and search engine optimization. By focusing on incoming links, this graph helps identify authority and relevance of web pages based on their backlinks.
