TLD vs Sub Domain in Regards to Domain Authority

[kchandler]

I have always been under the impression that top level (or root) domains can hold different domain authority than that of a sub domain. Meaning that sub domain's and TLD can hold different ranks and strength in search engine result pages. Is this a correct or just an assumption?

If so when i add a root domain and subdomain into the campaign manager i get back the same link information and domain authority?

www.datalogic.com
www.automation.datalogic.com

Have I made an incorrect assumption or is this an issue with the SEOMoz campaign manager?

A subdomain is considered a separate website. This is why it is considered good SEO to pick between domain.com and www.domain.com and 301 one to the other (most pick www). This means that your new subdomain might as well be a new domain entirely. You'll have to do a new campaign.

As far as seomoz goes, I am not sure why they would aggregate it like that. Would probably need to ask the staff if it's a bug

Hi Kyle,

That does sound strange - did you set up www.automation.datalogic.com as a Subdomain (as opposed to a Root Domain - see: http://pro.seomoz.org/campaigns/new) within the Campaign Manager set up?
