Is there a way to get the domain authority of a subdomain?

[Whitespark]

For example, www.storage-mart.com and us.storage-mart.com both show the same DA in OSE. I believe it's the DA of the root domain. How can I compare the DA of the 'www' and 'us' subdomains?

I don’t think there is a way to get the DA of a sub-domain as sub domains are the part of the overall domain and this is why it contains the same domain authority as the main.

The way to check the power of the sub-domain should be checked by PA in my opinion (for that URL only). I do understand that Google count sub domains as a separate entity but i don’t think this leads to have a different DA of a sub-domain then the main domain.

Just my opinion!

Yes, currently unsupported according to help source document on the subject. I believe it's an area of SEO that justifies separate scoring. Of course, analytic software would provide its own metrics.

I agree with Moosa, but it may make sense to also look at mozrank for the subdomain - OSE calls it subdomain mozrank, which would look at the strength of the whole subdomain. you can also look at the number of linking root domains and followed linking root domains, compare that to the total numbers for the domain, and determine how much of the overall strength of the domain authority is resultant from the particular subdomain you're looking at. Those are just my theories, but to me it makes sense

Hey guys, thanks for your responses. Running a comparison and looking at Page Authority and Subdomain Mozrank gives me exactly what I need. I just want to be able to see which is stronger, and this does a good job of telling me.
