      My IT department tells me they want to transfer my main site domain, which has been in existence since 1999 as an e-commerce site (maindomain.com) to a sub-domain (www2.maindomain.com) or a completely new domain (newdomain.net). This is because we are launching a new website and B2C e-commerce engine, but we still have to maintain the legacy B2B e-commerce engine which contains hard-coded URLs, and both systems can't use the same domain.

      I've been researching the issue across SEOmoz, but I haven't come across this exact type of scenario (mostly I've seen a sub-domain to new domain).

      I see major problems with their proposal, including negative SEO impact, loss of domain authority/ranking and issues with branding.

      Does anyone know the exact type of impact I can expect to see in this scenario and specific steps I should go about to minimize the impact?

      Btw, I will be using Danny Dover's guide on properly moving domains where appropriate.

      Thanks!

        It goes without saying but also ensure that as well as 301'ing all the old URL's, that you create a robots.txt to stop Google potentially spidering the new subdomain which contains the legacy files.

        Best of luck!

          If the current site is getting a lot of traffic and the new site would be a drastic change from the current site, I would look into hiring a coder to fix the hardcoded urls issue.

          Everything you mentioned is plausible if not probable including negative SEO impact, loss of domain authority/ranking and issues with branding.

          If the new site is going to be on different pages, make sure you 301 redirect the old pages to the new subdomain/domain. Aside from that, can't really do much =/

          Good luck,
          Oleg

            Cross Canonicalization for domains with same menu

            sharing menu items

            I have a client who took 3 pages from its main website and made them into their own domains. So that now, for example,
            www.mainsite.com/page
            redirects to
            www.page.com This is so users can be given access to the content on that specific page with ease.
            Now, www.page.com has the same menu items as www.mainsite.com, so that users who select the menu items on www.page.com will be circled back to the main site. But this means that there are now different URLs for these pages.
            ie:
            On www.mainsite.com there is: www.mainsite.com/menu-item
            (the content resides here) And on www.page.com there is: www.page.com/menu-item
            (Which is basically "scaffolding" to support the page and a means to get around, so to speak.This is to make any and all pages accessible at either domain. ) I have only seen this type of URL on the Moz campaign crawl. In the real world, when a user selects a menu item from the www.page.com, it will circle back to www.mainsite.com/menu-item SEO-wise, should I use cross-canonicalization to point www.page.com/menu-item to www.mainsite.com/menu-item? Or would this be splitting hairs since these are only seen on the Moz crawl?

            Redirect multiple domains to 1 domain or not?

            Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
            I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers

            Are .clinic domains effective?

            We acquired a .clinic domain for a client, they are right now running under a .ca and I was just wondering if there were any cons to making the switch. On the flip side are there any pros? I've tried to search for the answer but couldn't seem to come across anything, thank you if you have any knowledge or could point me to a resource.

            Subdomain vs Main Domain Penalties

            We have a client who's main root.com domain is currently penalized by Google, but the subdomain.root.com is appearing very well. We're stumped - any ideas why?

            Localized domains and duplicate content

            Hey guys, In my company we are launching a new website and there's an issue it's been bothering me for a while. I'm sure you guys can help me out. I already have a website, let's say ABC.com I'm preparing a localized version of that website for the uk so we'll launch ABC.co.uk Basically the websites are going to be exactly the same with the difference of the homepage. They have a slightly different proposition. Using GeoIP I will redirect the UK traffic to ABC.co.uk and the rest of the traffic will still visit .com website. May google penalize this? The site itself it will be almost the same but the homepage. This may count as duplicate content even if I'm geo-targeting different regions so they will never overlap. Thanks in advance for you advice

            How to 301 multiple domain names to a single domain

            Hey, I tried to find and answer to this seemingly simple question, but no luck. So, I have one domain name with a website attached to it. I also registered all the other domain names that are similar to it or have different extensions - I want to redirect all the other domain names to my one main domain name without getting penalised by the big G. It looks like this: www.mainsite.com - this is my main domain I also have www.mainsite.com.au, www.mainsite.org, and www.mainsite.org.au which I all want to just redirect to www.mainsite.com I have been told that the best way to do this is a 301 redirect, but to do that you need to make a CNAME for all the other domains that points to www.mainsite.com. My problem is that I cannot seem to create a CNAME record for http://mainsite.com - I have it working for http://www.mainsite.com but not the non www record. What should I be doing differently? Is it just my DNS provider is useless? Thanks, Anthony

            Using hyphenated sub-domains or non-hyphenated sub-domains? What is the question! I Any takers?

            For our corporate business level domain, we are exploring using a hyphenated sub-domain foir a project. Something like www.go-figure.extreme.com I thought from a user perspective it seems cluttered. The domain length might also be an issue with the new Algorithm big G has launched in recent past. I know with past experience, hyphenated domains usually take longer to index, as they are used by spammers more frequently and can take longer to get out of the supplementary index. Our company site has over 90 million viewers / year, so our brand is well established and traffic isn't an issue. This is for a corporate level project and I didn't have the answer! Will this work? anyone have any experience testing this. Any thoughts will help! Thanks, Rob
