Hello everyone ! I am planning to buy a domain with a Page Rank. I would like to believe that most domains of this kind are being sold as they are about to lose their PR in the next update. What I would like to know is that how can we maintain the PR of such a domain and minimize its chances of losing PR. I have researched on this subject and found out that most of these domains don't have back links, but they still have a PR. Can someone explain how does that happens and also that does that indicates that they have been drooped as to my understanding, a domain/website achieves a PR due to quality back links. Pls let me know. Thanks, SF
