Two different page authority ranks for the same page

[trophycentraltrophiesandawards]

I happened to notice that trophycentral.com and www.trophycentral.com have two different page ranks even though there is a 301 redirect.  Should I be concerned?

http://trophycentral.com

Page Authority:  47

Domain Authority:  42

http://www.trophycentral.com

Page Authority:  51

Domain Authority:  42

Thanks!

If you have a 301 in place it shouldn't be an issue, although if it has only recently been added, it might take a bit of time for Google to catch up. if the 301 been added recently it might explain why it is showing up with a different page auth in Open site explorer as the OSE database is only updated once a month or so

If you want to take the belt and braces approach you could always add in a rel=canonical to http://www.trophytcentral.com/

Make sure you add in the trailing slash

Hope that helps
