      Hello Mozzers!

      Couple of days ago I received a request to start optimizing a wordpress website, the domain itself has been around for around 10-12 years so it's it can be considered as one that has real history behind it.  The page has been moved from HTML/FLASH to wordpress about 3 - 4 years ago and hasn't been any SEO maintenance on it. The site used to rank for first position with several keywords, but now understandably, it has greatly decreased.

      My main question would be, that when I've checked the root domain's and the subdomain's metrics with MOZ Open Site Explorer, the sub domain (with "www.") showed a PA 40 and 90 external links while the root domain (without "www.") only has 27 PA and 6 External links.

      I know that the 301 or server redirects only transfers about 90% of the link juice to the targeted URL but the difference between the 2 results seem way too big for me.

      What do you think? Is this normal?
      During future link building is it more beneficial to target the root domain so the page won't lose that "10%" by redirecting the new link from sub-domain to root domain?
      Is it possible to get more juice transferred?

      Thank you very much,
      Adam

        Hey

        I'm a bit confused - not the first time! Would very much appreciate if you good folks could shed some light on a couple of questions.

        Our site in the search console is inputed as www.domain.co.uk

        Is this our subdomain?

        When I'm using Open Site Explorer and filter by Target, say "this root domain" is it now showing me inbound links to domain.co.uk instead?

        Lastly how does this affect rankings i.e getting links to www.domain.co.uk or domain.co.uk as whoever types in either domain gets to the correct site.

          Thank you CKG for your answer, it's much appreciated.

          I have already started to move to www. , I changed in WordPress settings, from non-www to www version, also selected the preferred version www. in webmaster tools and contacted the server administrators about the change. My only last problem is the battle with the htaccess to redirect the rootdomain to the www. subdomain but I should get it sorted out pretty soon 🙂

          Cheers,
          Adam

            Hey

            I think  you should go through both for analysis purposes however in order to moving forward you should be focusing on one URL which contains www.

            here are the link for you to help yourself to understand the difference between these.

              I have just come across the same issue for a site I am optimising. For me, when www is used the page authority in OSE is 42 compared to 33 when there is no www.

              It would be really good to hear what people's views are on this.

                Redirecting dofollow, high-domain-authority links from one site to another: good idea?

                I have two sites that offer help for freelance writers. The first gets almost no search traffic and is very low priority for me. The second is my main priority and gets substantial search traffic. The low-priority site has a significant number of dofollow backlinks from high-domain-authority sites. Is it a good idea to 301 redirect these links to similar/related posts on my high-priority site? Would this potentially boost the SEO of my high-priority site? Thanks for any help!

                Would you consider these domains spammy or at risk for penguin penalty?

                I'm doing a bit of competitor backlink auditing and am curious how you view these domains? I also am doing this for others as a comparison and growing reference maybe of domains that they can crosscheck with their own backlink profile and make sure these aren't on there, in preparation for penguin algo release to core. Either chime in with known domains to be spam, and I will create a live list based on answers here. Domain                     Domain Rating directoryworld.net     64

                Backlinks from domains that are not indexed...

                Would you count them as spammy and disavow?

                Subdomains vs Subfolders

                I've had a good read on this one and just wondered whether the info on the below link is still valid 3 years on: http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites My main site is a forum but I want to add further content in the form of a blog.  It seems logical to me that domain.com/blog/ would make more sense than blog.domain.com as the the content and inbound links to the blog would also help the forum where it's on the same subdomain, however I just wanted to make sure that was still the case as I've also read that Google now see a subdomain and subfolder in the same way if set up correctly in webmaster tools and this solution would look neater if that was the case. Thanks all.

                Unique Domains vs. Total Links?

                At what point is there diminishing returns from getting multiple links from one website? Edit: To clarify, when doing competitor research I come across lots of sites that have say 500 linking domains with 5000 total links. When setting goals and calculating the types of links I should go after, I'm not certain which number is the one actually helping the site to rank.

                Domain Authority and nofollow links?

                Hello, I'm wondering, are 'nofollow' links from websites with high domain authority beneficial? Would they boost our own DA? In essence, I'm wondering if there is added value (other than visitors clicking the link) to being linked to by a 'nofollow' link. Thanks!
