Hi all,

I change its nameserver to my own hosting,after I addon it,the I check the pr it become not valid.

Can anyone help me figure it out?
Thought I'm a newbie here.
Thx

 

First, we need the domain name to see if it was just a temporary issue. However, I do know there are methods to fake a domain's Pagerank. Did you check the Pagerank of the root domain with and without index.php|html|asp? There is a chance you just got stuck with a domain name that had a fake Pagerank.

 

I didn't.how to check the domain root?
