Page Rank & Link Quantity Calculation


The following chart is based on the Google pagerank calculation for how it calculates the PR of an individual page and what is required for certain pageranks.  Use it as a guide and an estimation only.

How to do I interpret this information?


This chart gives you an estimation of what your page rank would be, had all the pages linked to you been PR 1 to 10.  Of course as is generally the case there will be many more lower ranked websites linking to you than higher ranked websites.  My suggestion is to use a tool to find the average PR of the websites linking to you.
 

What do the ranges represent

The "Start Range", "End Range", and "Median Value" show how many votes a website with that particular PageRank would be expected to have to justify a certain Pagerank score.  Since a single website might only just qualify to be a Pagerank 5, it might have only 5,033 votes cast for it while a strong Pagerank 5 website would be expected to have up to 27,213 votes.
 
Please remember that the amounts of links are estimates and in no way can be 100% accurate because there are many other factors involved in how much link juice a website gets from an individual link to it.
