      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?

        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.

        http://www.opensiteexplorer.org/comparisons?site=www.storage-mart.com&comparisons%5B0%5D=us.storage-mart.com

        Thanks!

          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

            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 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!

                Removing Domains From Disavow File

                We may have accidentally included the wrong domains in our Disavow file and have since removed most domains leaving the only very highly rated spammy links (using moz's new spam score)in the file. How long can it take for to google to recognise this change?ThanksMike

                Domain Audit

                Hi What is the best tool out there to doing a full brand audit for company.  They've created at least 15 websites and have possibly many domain names which have been ordered by different people over many years. I need to find the quickest and best tool to do this with. Any suggestions would be great.

                Domain / Page Authority - logarithmic

                SEOmoz says their Domain / Page Authority is logarithmic, meaning that lower rankings are easier to get, higher rankings harder to get. Makes sense. But does anyone know what logarithmic equation they use? I'm using the domain and page authority as one metric in amongst other metrics in my keyword analysis. I can't have some metrics linear, others exponential and the SEOmoz one logarithmic.

                My page has a 302 redirect and I don't know how to get rid of it!

                I use Internet Officer tool to see the 302 redirect but I check the redirects in the CPanel and there are none. In the .htaccess there are none either. I don't know where else to look 😞 The url is http://servicioshosting.com Can you guys help me? I can't set up a campaign because Google can't crawl the website. I can't setup the Facebook OpenGraph because of the redirect. error.jpg

                Why are my sub-domains ranking higher than my Root Domains?

                I have just noticed that my sub-domains are ranking higher in Mozrank and Moztrust than the root domain - that seems nuts. Am I doing something wrong?

                How to check Page Authority in bulk?

                Hey guys, I'm on the free trial for SEOmoz PRO and I'm in love. One question, though. I've been looking all over the internet for a way to check Page Authority in bulk. Is there a way to do this? Would I need the SEOmoz API? And what is the charge? All I really need is a way to check Page Authority in bulk--no extra bells and whistles. Thanks, Brandon

                Spam Directories creating misleading Authority ratings

                How does the website www.starsdirectory.com.ar get a Domain Authority of 54 and a Page Authority of 61 when Google quite correctly gives it a PR 0? It is clearly a spam directory, which Google has recognised. It is very misleading using OSE or Campaign Management when sites such as these (and there are hundreds more we have found) are skewing the results of competitiors through the use of spam links. Is there no way that SEOMoz tools can identify such spam sites when they create their ratings?
