I am still waiting for the July pr update. I wonder what the big G is up to with this long delay?
PR can be faked, and G may drop the PR to 0 if the site is replaced by an empty domain sales page/placeholder.
If you bought an expired, it had pr and you built a site on it and now the pr has dropped - some of the original links have probably been pulled.
Nope, just links and any penalty G may give.Does a change in domain ownership impact PR?
