      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

            Old domain to new domain

            Hi, A website on server A is no longer required. The owner has redirected some URLS of this website (via plugin) to his new website on server B  -but not all URLS. So when I use COMMAND site:website A , I see a mixture of redirected URLS and not redirected URLS.Therefore two websites are still being indexed in some form and causing duplication. However, weirdly when I crawl with Screaming Frog I only see one URL which is 301 redirected to the new website.  I would have thought I'd see lots of URLs which hadn't been redirected. How come it is different to using the site:command? Anyway, how do I move to the new website completely without the old one being indexed anymore. I thought I knew this but have read so many blogs I've confused myself! Should I: Redirect all URLS via the HTACESS file on old website on server A? There are lots of pages indexed so a lot of URLs. What if I miss some? or Point the old domain via DNS to server B and do the redirects in website B HTaccess file? This seems more sensible but does this method still retain the website rankings? Thanks for any help

            How can you promote a sub-domain ahead of a domain on the SERPs?

            I have a new client that wants to promote their subdomain uk.imagemcs.com and have their main domain imagemcs.com fall off the SERPs. Objective? Get uk.imagemcs.com to rank first for UK 'brand' searches. Do a search for 'imagem creative services' and you should see the issue (it looks like rules have been applied to the robots.txt on the main domain to exclude any bots from crawling - but since they've been indexed previously I need to take action as it doesn't look great!). I think I can do this by applying a permanent redirect from the main domain to the subdomain at domain level and then no-indexing the site - and then resubmit the sitemap. My slight concern is that this no-indexing of the main domain may impact on the visibility of the subdomains (I'm dealing with uk.imagemcs.com, but there is us.imagemcs.com and de.imagemcs.com) and was looking for some assurance that this would not be the case. My understanding is that subdomains are completely distinct from domains and as such this action should have no impact on the subdomains. I asked the question on the Webmasters Forum but haven't really got anywhere
            https://productforums.google.com/forum/#!msg/webmasters/1Avupy3Uw_o/hu6oLQntCAAJ Can anyone suggest a course of action? many thanks, Nathan

            Redirect typo domains

            Hi, What's the "correct" way of redirecting typo domains? DNS A record goes to the same ip address as the correct domain name Then 301 redirects for each typo domain in the .htaccess Subdomains on typo urls still redirect to www or should they redirect to the subdomain on the correct url in case the subdomain exists?

            Redirect root domain to www

            I've been having issues with my keyword rankings with MOZ and this is what David at M0Z asked me to do below.   Does anyone have a solution to this?  I'm not 100% sure what to do.  Does it hurt ranking to have a domain at the root or not?  Can I 301 redirect a whole site or do I have to do individual pages. "Your campaign is looking for rankings for the www version of the campaign but the URL resolves as a root domain. This would explain the discrepancy. Since there is no re-direct between the two, you can have brickmarkers.com 301 re-direct to www.site.com  which will prevent you from re-creating your campaign to track the root domain. Once the re-direct is in place it will take a while for Google to show the www version in the results in which your campaign rankings will be accurate." Thanks

            Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?

            Dear all, starting with my .htaccess file: RewriteEngine On
            RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
            RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html 
            RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
            2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

            Beating a keyword Domain

            Has anyone here managed to beat a keyword/exact match domain to top spot? I am currently second and wondering if it is worth the time and effort to knock it off the top spot. How hard is it to get these very annoyingly favoured domains off 1st? Any help and advice much appreciated.

            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?
