Looking at the value of a backlink, I see sites that have a high (PR5 and up) homepage but every other page throughout the site is grey-bar. What does that indicate? thanks
it indicate that's its probably a dropped domain, if the owner is advertising it as a real pr5, then he is a scammer.
It could be possible that the site is INCREDIBLY unspiderable, but that would be a very rare case. Brandon
it may be dropped domain (you can check the domain create date for being sure) or google did not assigned pr for them until now
