      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

            Domain still not being found in search

            Hi guys, I've been handed a client who needs some seo work. I've tweaked one of their pages to focus on a chosen keywords about 4 months back but still the site is not even visible using the new Domain Analysis tool from moz and it still won't rank at all for the keywords. Am I missing something here? Is there something blocking the SERP from listing the website? I've ran a site: search on Google and it returns 283 results on the website. It's puzzling me as there clearly is something stopping it from being ranked. The domain name in question is: https://cloud9inecommunications.co.uk Thanks in advance.

            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!

            What to do with a site of >50,000 pages vs. crawl limit?

            What happens if you have a site in your Moz Pro campaign that has more than 50,000 pages? Would it be better to choose a sub-folder of the site to get a thorough look at that sub-folder? I have a few different large government websites that I'm tracking to see how they are fairing in rankings and SEO.  They are not my own websites.  I want to see how these agencies are doing compared to what the public searches for on technical topics and social issues that the agencies manage.  I'm an academic looking at science communication.  I am in the process of re-setting up my campaigns to get better data than I have been getting -- I am a newbie to SEO and the campaigns I slapped together a few months ago need to be set up better, such as all on the same day, making sure I've set it to include www or not for what ranks, refining my keywords, etc. I am stumped on what to do about the agency websites being really huge, and what all the options are to get good data in light of the 50,000 page crawl limit.  Here is an example of what I mean: To see how EPA is doing in searches related to air quality, ideally I'd track all of EPA's web presence. www.epa.gov has 560,000 pages -- if I put in www.epa.gov for a campaign, what happens with the site having so many more pages than the 50,000 crawl limit?  What do I miss out on?  Can I "trust" what I get? www.epa.gov/air has only 1450 pages, so if I choose this for what I track in a campaign, the crawl will cover that subfolder completely, and I am getting a complete picture of this air-focused sub-folder ... but (1) I'll miss out on air-related pages in other sub-folders of www.epa.gov, and (2) it seems like I have so much of the 50,000-page crawl limit that I'm not using and could be using.  (However, maybe that's not quite true - I'd also be tracking other sites as competitors - e.g. non-profits that advocate in air quality, industry air quality sites - and maybe those competitors count towards the 50,000-page crawl limit and would get me up to the limit? How do the competitors you choose figure into the crawl limit?) Any opinions on which I should do in general on this kind of situation?  The small sub-folder vs. the full humongous site vs. is there some other way to go here that I'm not thinking of?

            Why my Domain Authority (DA) is Decreased from 21 to 19?

            Hello, I would like to know how the changes in domain authority is counted by MOZ? Domain Authority for my this domain http://www.grandcrayon.ca/ was 21 and it is decreased to 19 in last week. I have checked the moz report and it shows DA as 19. We already have grandcrayon.ca and we recently redirected our .com domain (http://www.grandcrayon.com also to .ca so all the back links of .com are now showing in webmaster for .ca. So i would like to know the reason behind decrement in DA and is there any connection with redirection of .com domain? How can i increase DA for my website?

            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.

            Page Authority is the same on every page of my site

            I'm analyzing a site and the page authority is the exact same for every page in the site. How can this be since the page authority is supposed to be unique to each page?

            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?
