How often does google pr change
 

How often does google change the pr for a page. ?

Is there any way to get a domain out of google's blacklist.

I purchased some domains a few months back and they are all pr 4 or above , except 1 , and i think it must be blacklisted.

Has anyone ever got a domain off google's blacklist ?

pr updates every 4 to 6 weeks i have noticed

google usually un-blacklists domains once a yr

follow googleguy's posts at webmasterworld

Thanks. Ill do that. I have noticed about every 4=5 weeks as well , but i wasnt sure if sometimes none of my sites changed pr and it may have been sooner.

Post on WebmasterWorld a few times and ask Googleguy honestly if the site is blacklisted or not. He is pretty good about that stuff over there.

thanks:thumbsup
