Google Search Engine Trustrank
 

TrustRank is the use of a seed list of trusted web sites that have been reviewed by humans at Google, Stanford and other information retrieval (IR) professionals to be free of spam type link tactics. Then any sites that are linked to from these trusted groups of sites get higher PageRank (PR) and search engine rankings due to this TrustRank status.

I have found some of the usefull information at

As per my idea TR and PR are not directly related, PR is determined on the number of links to your site, TR is based with the quality of the links to your site. So To get good TR you need an older, well established site with relevant backlinks and good resources for your visitors.

hi,

yes Google have patented trustrank but we can't be sure if they have implemented it yet.

Trustrank isn't just about your backlinks though, it's about the backlinks of the people who backlink to you, and the backlinks of those sites and so on..... It's like a long chain. It's very hard for SEO's to manipulate, which will no doubt make Google happy.... haha

Cheers,
Paz.

Google is running and we SEO's Are after Google
