      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

            Images on sub domain fed from CDN

            I have a client that uses a CDN to fill images, from a sub domain ( images.domain.com). We've made sure that the sub domain itself is not blocked. We've added a robots.txt file, we're creating an image sitemap file & we've verified ownership of the domain within GWT. Yet, any crawler that I use only see's the first page of the sub domain (which is .html) but none of the subsequent URL's which are all .jpeg. Is there something simple I'm missing here?

            Block Domain in robots.txt

            Hi. We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off... Any ideas why this could be and whether it's normal? I can send you more domain infos by personal message if you want to have a look at it.

            Multilingual Website - Sub-domain VS Sub-directory

            Hi Folks - Need your advice on the pros and cons of going with a sub-domain vs a sub-directory approach for a multi lingual website. The best would be a ccTLD but that is not possible now, so I would be more interested in knowing your take on these 2 options. Though, I have gone through http://www.stateofsearch.com/international-multilingual-sites-criteria-to-establish-seo-friendly-structure/ and this somewhat vouches for a sub-directory, but what would you say'?

            Multiple Domains on 1 IP Address

            We have multiple domains on the same C Block IP Address. Our main site is an eCommerce site, and we have separate domains for each of the following: our company blog (and other niche blogs), forum site, articles site and corporate site. They are all on the same server and hosted by the same web-hosting company. They all have unique and different content. Speaking strictly from a technical standpoint, could this be hurting us? Can you please make a recommendation for the best practices when it comes to multiple domains like these and having separate or the same IP Addresses? Thank you!

            Subdomain and Domain Rankings

            I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league)  when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks

            Delete old site but redirect domain to a new domain and site

            I just have a quick query and I have a feeling about what the answer is so just wanted to see what you guys thought... Basically I am working on a client site. This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?

            Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains

            Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's  pointing to the same IP address as our "preferred domain:"  for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP.  This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain.  We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w.  This seemed to help resolve the issue and moved hundreds of pages off the index.  However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain.  When you click on the link, it does redirect to the same page but under the preferred domain.  So the redirect is working and has been confirmed as 301.  But for some reason Google continues to crawl our site and index under this incorrect domains.  Why is this? Is there a setting we are missing?   These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing.  Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.

            Outranking a competitor when their domain name is the keyword

            Hi I'd just like to ask the opinion of my fellow members here : We are currently ranking second for a very important keyword and would obviously like the top spot on the SERP - the site that is ranking first has the domain name as the keyword phrase(along with a good amount of quality links from a variety of domains) - now I know it is possible to outrank them since I do remember reading about this in one of Rands posts(I think it was the whole white hat black hat one he posted recently) - bascially we have more domain authority, slightly less links but from double the amount of root domains and a higher page authority too! Does having the keyword as your domain make THAT much of a difference when we are(imo) quite close in terms of great content and link profiles(and all the onpage factors) ? Thanks!
