      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?

        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?

          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

            I bought a 5 year old domain and has a spam score of 23%.....

            A few months ago i bought a 5 year old domain and when i went to check in Moz pro the spam score, it shows its at 23%. DA is 1 everything else is 0. The spam score shows 23% but there are no links at all for this website (see image) https://imgur.com/a/3lHjLEh I don't understand, there are no links at all going to this website. I checked google search console, analytics and tried looking for any links linking to this domain and there is none. Even Moz isn't showing any links in the picture i provided above. Is this a glitch? Can i reset my spam score on this domain? Does that mean i wasted my money on this domain and now i can't rank with it? Is there something im missing here. I also checked is there are any warnings or manual actions and it clearly says "No issues detected". A few months earlier i bought a brand new domain very close to the 5 year old domain (new domain has a z instead of an s) and the spam score on that is 0 and DA is 1. Given that the 5 year old domain has a 23% spam score, does that mean i should use the other new domain instead and redirect the 5 year old domain to the new website?

            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

            Url-delimiter vs. SEO

            Hi all, Our customer is building a new homepage. Therefore, they use pages, which are generated out of a special module. Like a blog-page out of the blog-module (not only for blogs, also for lightboxes). For that, the programmer is using an url-delimiter for his url-parsing. The url-delimiter is for example a /b/ or /s/. The url would look like this: www.test.ch/de/blog/b/an-article www.test.ch/de/s/management-coaching Does the url-delimiter (/b/ or /s/ in the url) have a negative influence on SEO? Should we remove the /b/ or /s/ for a better seo-performance Thank you in advance for your feedback. Greetings. Samuel

            GWMT / Search Analytics VS OpenSiteExplorer

            Just had the experience of using OSE data to show what we call "linkrot" to a client -- only to find that GWMT / Search Analytics shows no such thing. Fortunately the client is an old friend and no face was lost, but it was dicey there for a bit as I have come to rely on and reference OSE again and again and again, OSE showed Domain Authority dropping by about 1/3 in the last 12 months, presumably due to old links getting broken, linking sites changing their architecture etc. And of course, ranking is tanking, as you would expect. But Google shows many more (and much more spammy looking!) backlinks. Has anyone had any experience benchmarking the 2 data sets of backlinks against each other?  Dr Pete?
            Does one update more frequently than another? Do you trust one more than another?? If so, why?? Thanks!

            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.

            What is the logarithmic scale used for domain authority?

            I want to quantify how much better a score of 80 is compared to 60. Or 60 compared to 30 etc.... What is the logarithm base? Thanks, Rik

            How to increase page authority

            I wonder how to increase the page authority or the domain authority to begin with. It seems you are putting a lot of weight on this in your analysis.

            Why do some sites have a higher Page Authority than Domain Authority in OSE??

            Hi, I have noticed when using OSE and enter a domain you very often see a higher Page Authority than Domain Authority. If someone could explain why this would happen then I would be very grateful - its my current understanding that page authority would ALWAYS be LESS THAN Domain Authority but that is not always the case (I have seen cases where PA is more than 10 higher then DA) Here's an example where PA > DA http://www.opensiteexplorer.org/links.html?site=www.primelocation.com Thanks
