      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

            Moz Domain Authority [Megathread]

            domain authority da

            Hey Moz Community, We've noticed that there are questions about Domain Authority, what it is, and how to positively impact it. We're here to answer your questions! For a full overview, please see our help hub article here: https://moz.com/learn/seo/domain-authority First, it's important to keep in mind that Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). It is not a Google ranking factor. Domain Authority scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking. Since DA is based on machine learning calculations, your site's score will often fluctuate as more, fewer, or different data points become available and are incorporated into those calculations. For instance, if facebook.com were to acquire a billion new links, every other site’s DA would drop relative to Facebook’s. Because more established and authoritative domains like Facebook will have increasingly larger link profiles, they take up more of the high-DA slots, leaving less room at the higher end of the scale for other domains with less robust link profiles. Therefore, it's significantly easier to grow your score from 20 to 30 than it is to grow it from 70 to 80. For this reason, it’s important to use Domain Authority as a comparative metric rather than an absolute one. The best way to influence your DA is to improve your overall site health with a focus on the quality and quantity of external links pointing to your site. Check out this video for more details on how to impact DA Happy analyzing!

            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

            Automatically Check List of Sites For Links To Specific Domain

            Hi all, Can anyone recommend a tool that will allow me to put in a list of about 200 domains that are then checked for a link back to a specific domain? I know I can do various link searches and use Google site: command on a site by site basis, but it would be much quicker if there was a tool that could take the list of domains I am expecting a link  on and then find if that link exists and if so on what page etc. Hope this makes sense  otherwise I have to spend a day doing it by hand - not fun! Thanks,
            charles.

            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.

            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?

            Root domain or sub domain

            When I crawl my site as a root domain, I get more errors is my campaign than when I set my site as a sub domain. Which one is the correct way: root domain or subdomain. My site is www.aa-rental.com

            How fast can page authority be grown

            I understand that it is easier to rank for a particular keyword given a higher DA score. How fast can  page authority be established and grown for a given keyword if DA is equal to 10/20/30/50? What are the relative measures that dictate the establishment and growth of this authority? Can it be enumerated to a percentage of domain links? or a percentage of domain links given an assumed C-Block ratio? For example you have a website with DA of 40, and you want to target a new keyword, the average PA of the top ranked pages is 30, the average domain links are 1,000, and the average number of linking domains is 250 - if you aim to build 1,000 links per month from 500 linking domains, how fast can you approximate the establishment of page authority for the keyword?

            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?
