Definition
A link graph is a representation of the hyperlink structure of a network, where nodes represent entities such as web pages, and edges represent the hyperlinks or connections between these entities. It is used to model relationships and interactions within the network, capturing how entities are interconnected through links.
User Cases
Link graphs are commonly used in analyzing the structure of the World Wide Web, where each node is a web page and each edge is a hyperlink. They help in understanding how information flows across the web and are crucial for applications like search engine optimization, where the connectivity of a page can influence its ranking. Additionally, link graphs are used in social network analysis, where they help visualize and study the connections between individuals or groups.
Why It Matters for SEO

Pages that are well-connected within a link graph are often seen as more authoritative and are likely to rank higher in search engine results. Understanding and optimizing the link graph of a website can lead to improved visibility and traffic, as it helps in building a robust link profile that search engines favor.
