      Just a quick one, i have the following example scenario.

      Main Domain: http://www.test.com

      Sub Domain: http://sub.test.com

      What I am wondering is I can add onto the sub domain a rel=canonical to the main domain. I dont want to de-index the whole sub domain just a few pages are duplicated from the main site.

      Is it easier to de-index the individual sub domain pages or add the rel=canonical back to the main domain.

      Much appreciated

      Joseph

        Canonicalizing http://sub.test.com to http://www.test.com will tell Google that those two individual pages are the same and it should only index http://www.test.com--it won't affect other pages on the subdomain.

        If you only have a few subdomain pages that are duplicates of root domain pages, you can just use canonicals to indicate which pages you want indexed. You won't need to noindex the duplicate ones--they will fall out of Google's index naturally once Google sees which are the preferred, canonical ones.

          Hi there,

          The Rel=canonical will not de-index those pages.

          To de-index, add a rel=robots with a noindex tag. And also add the rel=canonical or just redirect 301 the page. Of course, do it to those selected pages only.

          Hope it helps.
          GR.

            Dealing with links to your domain that the previous owner set up

            Hey everyone, I rebranded my company at the end of last year from a name that was fairly unique but sounded like I cleaned headstones instead of building websites. I opted for a name that I liked, it reflected my heritage - however it also seems to be quite common. Anyway, I registered the domain name as it was available as the previous owner's company had been wound up. It's only been in the last week or two where I've managed to have a website on that domain and I've been tracking it's progress through Moz, Google & Bing Webmaster tools. Both the webmaster tools are reporting back that my site triggers 404 errors for some specific links. However, I don't have or have never used those links before. I think the previous owner might have created the links before he went bust. My question is in two parts. The first part is how do I find out what websites are linking to me with these broken URL's, and the second is will these 404'ing links affect my SEO? Thanks!

            Hi i am a real newbie to this and i hope for a guide on how to do this. I seen a few moz post and is quiet confusing hopefully somebody able to explain it in layman terms to me. I would like to  301 redirect this way, both website contain the same niche. oldwebsite.com > newwebsite.com and also its pages..... oldwebsite.com/test >newwebsite.com/test So my question here is i would like to host my old domain and its pages in my new website hosting in order to redirect to my new domain and its pages how do i do that? would my previous page link overwrite my new page link? or it add on the juice link? Do i need to host the whole old domain website into my new hosting in order to redirect the old pages? really confusing here, thanks!

            Best Location to find High Page Authority/ Domain Authority Expired Domains?

            Hi, I've been looking online for the best locations to purchase expired domains with existing Page Authority/ Domain Authority attached to them. So far I've found: http://www.expireddomains.net
            http://www.domainauthoritylinks.com
            http://moonsy.com/expired_domains/ These site's are great but I'm wondering if I'm potentially missing other locations? Any other recommendations? Thanks.

            Penalised by Google - Should I Redirect to a new domain?

            Last month my rankings dropped a couple of pages on Google and am no longer receiving as many visits from Google as I used to. It's coming up to summer which is the time my business naturally picks up yet I can't fix this problem. I have a crazy idea of redirecting my established site onto a new domain in hopes that the penalty would be removed. I have tried removing any manipulative links yet my ranking are not coming back. Anyone had success in redirecting to a new domain?

            Separate domain name for a subdomain?

            I just created a subdomain to help our main TLD website. I was wondering if it's smart to create a separate TLD for this subdomain and set up a forward and build links to it. Reason I was thinking about it because it would be easier for people to remember instead of typing in subdomain.maindomain.com. But, I don't want the main website to suffer, since the purpose of creating this subdomain and it's content is to help the main domain. Any inputs on this? Thank you.
