          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

            I can't agree with Anirban's suggestion. A 301 redirect would be the superior solution.

              You should put a canonical tag on http://aa.rental.com point to http://www.aa.rental.com. When search engines bot sees the canonical tag it will crawlyour main site http://www.aa.rental.com and hence no dulicate content issue.

                Your site is published under multiple domains:

                http://aa-rental.com/

                http://www.aa-rental.com/

                Notice both of the above links brings up the same content on your site but under different URLs. That should not happen.

                http://seomoz.org/q/root-domain-or-sub-domain

                Notice if you try the above link for this Q&A response, the URL is changed to add the "www." subdomain. That is what should happen if you have a site presented on the www subdomain.

                You need to decide how you wish to present your site, with or without the www subdomain. Once that decision has been made, it needs to be enforced with server side code. Once that issue is resolved, the particular crawl issue you mentioned should be resolved.

                  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://a-moz.groupbuyseo.org/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!

                  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

                  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?

                  How is domain authority related to country top level domains?

                  I've noticed that for some country top level domains (tld) the domain authority returned by open site explorer is based on the domain that has been registered within the tld. For example, domainname.co.uk provides a domain authority specific to the domain. However, for some other country top level domains, this does not appear to be the case.  Examples I have found include: domainname.co.nr domainname.co.pt domainname.co.ee For these top level domains the domain authority seems to be the same for every domainname, seemingly implying the domain authority is for the top level domain itself rather than for the domain. Is this a common situation for many country top level domains, so that what I see going in here is the tip of a large iceberg, or does this situation just apply to a very isolated set of country top level domains?

                  Batch lookup domain authority on list of URL's?

                  I found this site the describes how to use excel to batch lookup url's using seomoz api. The only problem is the seomoz api times out and returns 1 if I try dragging the formula down the cells which leaves me copying, waiting 5 seconds and copying again. This is basically as slow as manually looking up each url. Does anyone know a workaround?

                  TLD vs Sub Domain in Regards to Domain Authority

                  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?
