Heyya I just found some expired domains that have 6 "pr 6" and 1 "pr 5" backlink the domain is pr0 because it's dropped from google cache. If I register that domains do I have chance to make them PR5? Note all domains have the same backlinks. Thanks
You can sell them at a higher price than what you register them for, if the backlinks are reasonably strong. They won't become PR5 on the next update unless the links have been acquired very recently. That would not happen as I do not think a PR5 site owner to link to a site which does not exist.
