      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

            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

            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?

            In alt tag of a image can we use #hashtag or domain.com ? Is that good SEO or not allowed ?

            Some of the Google Search shows a title has a hashtag of an article, which contain keyword and while tweeting them, the title which has a hashtag automatically very good used for getting traffic to the blog. And other one, can we use the hash tag inside the alt attribute ? Or our domain name with .com in it. Like Google.com or #Google ?

            HTC access 301 redirect rules regarding pagination and striped category base (wp)

            I am an admin of a wordpress.org blog and I used to use "Yoast All in one SEO" plugin. While I was using this plugin it stripped the category base from my blog post URL's. With yoast all in one seo: Site.com/topic/subtpoic/page/#
            Without yoast all in one seo: Site.com/category/topic/subtopic/page/# Now, that I have switched to another plugin, I am trying to manage the page crawl errors which are tremendous somewhere around 1800, mostly due to pagination. Rather than redirecting each URL individually I would like to develop HTC access 301 redirects rules. However all instructions on how to create these HTC access 301 redirect rules are regarding the suffix rather than the category base. So my question is, can HTC access 301 redirects rules work to fix this problem? Including pagination?  And if so, what would this particular HTC access 301 redirect look like? Especially regarding pagination? And do I really have to write a 301 redirect for each pagination page?

            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?

            Domain.com and domain.com/index.html duplicate content in reports even with rewrite on

            I have a site that was recently hit by the Google penguin update and dropped a page back. When running the site through seomoz tools, I keep getting duplicate content in the reports for domain.com and domain.com/index.html, even though I have a 301 rewrite condition. When I test the site, domain.com/index.html redirects to domain.com for all directories and root. I don't understand how my index page can still get flagged as duplicate content. I also have a redirect from domain.com to www.domain.com. Is there anything else I need to do or add to my htaccess file? Appreciate any clarification on this.
