It was a dark day in the SEO world when Google shut down their public service displaying the PR values for websites. Many software that heavily relied on this service had become obsolete overnight. We didn't like that this happened and wanted to bring back useful metrics that could help with ranking a website using values of 0 (worst) to 10 (best) and decided to build a software that is able to emulate the PR API based on metrics available from other services.
Get Google's PageRank (PR) back
Starting the software is enough to get PR working again. You can use all your programs that relied on PR and choose how to emulate the PageRank value. There are many things to choose from such as (TrustFlow, CitationFlow, Yandex, AlexaRank and many more).
