Description

The PageRank Calculator is a script I wrote in response to a paper written by Chris Ridings entitled, "PageRank Explained". In this paper, Chris describes how PageRank - a multiplying factor which is assigned to all web pages when Google is deciding which documents are most relevant in response to a search - is passed from page to page depending on the link structure of a web site. For search engine optimisers, the principal benefit is to reveal how a webmaster can influence how Google views the relative importance of pages on his or her site by carefully modifying the site's link structure.

The PageRank Calculator is designed to model the behaviour of the PageRank algorithm used by the Google search engine as described by Sergey Brin and Larry Page, the originators of Google, in their research paper, "The Anatomy of a Large-Scale Hypertextual Web Search Engine." By entering the link structure of a small web site of anything up to 50 pages into the calculator, you can get a good idea of which of the pages on the site Google will be viewing as most important.

NB.The PageRank Calculator is not a crawler: it will not crawl your web site for you and calculate its PageRank. It is simply a model. You will need to enter in the details of your web site's link structure in order for it to produce its calculations.
