Already we have one of the best list of Free SEO tools in market. http://www.searchenginegenie.com/seo-tools.htm . Now we are working on a new tool which will give predict the pagerank of a website based on their current pagerank plus user input values. Currently we don't have any real pagerank prediction tools in Internet. All the tools now either check various datacenters and display's the Pagerank or give some random values. But our tool will use partially use the Original Pagerank formula. Our programmers are doing their best to get user values and current pagerank to predict new pagerank.

Original pagerank formula:

:$PR(A)=\; 1\; -\; d\; +\; d\; \backslash left(\; \backslash frac\{PR(B)\}\{L(B)\}+\; \backslash frac\{PR(C)\}\{L(C)\}+\; \backslash frac\{PR(D)\}\{L(D)\}+\backslash ,\backslash cdots\; \backslash right)$

or (''N'' = the number of documents in collection)

:$PR(A)=\; \{1\; -\; d\; \backslash over\; N\}\; +\; d\; \backslash left(\; \backslash frac\{PR(B)\}\{L(B)\}+\; \backslash frac\{PR(C)\}\{L(C)\}+\; \backslash frac\{PR(D)\}\{L(D)\}+\backslash ,\backslash cdots\; \backslash right)\; .$
