  As the use of web is increasing more day by day, the web users get easily
lost in the web's rich hyper structure. The main aim of the owner of the
website is to give the relevant information according their needs to the users.
We explained the Web mining is used to categorize users and pages by analyzing
user's behavior, the content of pages and then describe Web Structure mining.
This paper includes different Page Ranking algorithms and compares those
algorithms used for Information Retrieval. Different Page Rank based algorithms
like Page Rank (PR), WPR (Weighted Page Rank), HITS (Hyperlink Induced Topic
Selection), Distance Rank and EigenRumor algorithms are discussed and compared.
Simulation Interface has been designed for PageRank algorithm and Weighted
PageRank algorithm but PageRank is the only ranking algorithm on which Google
search engine works.
