      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

            Solved How to reduce the spam score for my domain?

            spam score

            My domain  longfeifei.com is for a regular company website and someone sent a lot of external links on different low-quality websites on the internet. Now the score is very high about 75%. If I disavow the unusual links from google search console. Is it possible to reduce the spam score? Is MOZ associated with GOOGLE Data? Thanks,

            Ahrefs vs Moz

            Hi! I noticed the Moz DA en the Ahrefs DA are very different. Where https://www.123opzeggen.nl/ has a DA of 10 at MOZ, the DA at Ahrefs is 26. Where does this big difference come from? Do you measure in different ways? I hope you can answer this question for me. Thank you in advance!

            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

            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!

            MoZ vs SEMRush - Keyword Difficulty and Keyword With Low Competition.

            Hi, My question is very focussed regarding these 2 tools. Is it correct to understand that MoZ tells keyword difficulty and not which keyword is easy to compete. And SEMRush tells which keyword is easy to compete but does not tell which keywords are difficult to compete? I mean one (Moz)  misses the one part and the other (SEMRush) misses the other part. Hope some will enlighten me to the point. Best

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

            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?

            Hello, lets say I have domain www.example.com I want to track rankings of www.example.com/product and www.example.com/anotherproduct with different keywords, so do I have to set up 2 different campaigns? Or is it possilble to track whole root domain with paths? Thanks!

            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.
