If the domain has been dropped will google keep the PR on next update if all the inbound links remain?
As long as it keeps its backilinks and you can get a site up on it quick enough it will more than likely keep its PR value, if there are no backlinks then it will go in the next update. IMO
I guess you mean "if google does not show the backlinks..." since if it does not have backlinks then there is no way to keep PR as far as i know?
Thanks for the responses guys I have a few domains that are in this category and yes it seems they are keeping their PR however time will tell if that changes
I remember picking up a dropped domain name which had it's PageRank still in tact. I guess you could assume that if a domain is dropped and hasn't had a PR Update, it retains the PR? And by the time Google comes to the next update, it sees that it has a new owner, but the Pagerank still remained for me. You should install the GoDaddy Search Toolbar and the Google Toolbar. If you come across a dead domain which has PR, type it into GoDaddy and see if it's available. If not, install a toolbar for the WHOIS as well so you can see the WHOIS Information and if it might expire
If the domain has many backlinks! I hope they will keep the PR as I have a that kind of domain as well.
PR is determined by sites linking to you. So if there is no changes on the quality and quantity of the backlinks then the PR will remain as well.
