Link analysis is a technique used in information retrieval, search engine optimization, and web analysis to understand the relationships between various web pages and websites. It involves analyzing the links (hyperlinks) that connect different pages on the internet. Link analysis plays a crucial role in determining the importance, relevance, and authority of web pages. It helps search engines and algorithms like page ranking to evaluate and rank web pages based on their interconnectedness.

A page ranking algorithm is a method used to assign a numerical value or score to web pages, indicating their significance or relevance in relation to a particular query or topic. One of the most well-known page ranking algorithms is the PageRank algorithm, developed by Larry Page and Sergey Brin at Stanford University, which served as the foundation for Google's search engine.

PageRank Algorithm Example:
Let's consider a simple example to explain the PageRank algorithm. Imagine a small network of web pages:
