Crazy Pagerank

[SEOwins]

Can anyone shed any light on how the following site has managed to retain a Google Page Rank of 4?

We have just be asked to look at developing a new site.  This site has been inactive for 5 years.  From SEO perspective all seems wrong so how is it managing to achieve a PR4?

Thanks

PageRank is calculated based on backlinks. The link from this PR5 page probably helps a lot: http://www.netshinehosting.com/

Yes indeed but they only have 9 linking sites!

So one PR5 would not help !

SEOmoz only indexes a small portion of the web, so they likely have more than 9 linking sites. And yes, a PR5 link would definitely contribute to their PR4.

Majestic shows 220+ linking domains, and Majestic's index is still much smaller than Google.

Sorry but think you are missing the point.

I have sites that have 1000's of links all good quality and they only just scrape PR4.  This is a dead site with poor link profile, no content and inbuilt redirect and no activity for 5 years.

A couple of good links would not normally warrant a PR4.
