    Good morning,

    This is my first post.  I found many Q&As here that mostly answer my question, but just to be sure we do this right I'm hoping the community can take a peak at my thinking below:

    Problem: We are relevant rank #1 for "custom poker chips" for example. We have this development website on a subdomain (http://dev.chiplab.com).  On Saturday our live 'chiplab.com' main domain was replaced by 'dev.chiplab.com' in the SERP.

    Expected Cause: We did not add NOFOLLOW to the header tag. We also did not DISALLOW the subdomain in the robots.txt. We could have also put the 'dev.chiplab.com' subdomain behind a password wall.

    Solution: Add NOFOLLOW header, update robots.txt on subdomain and disallow crawl/index.

    Question: If we remove the subdomain from Google using WMT, will this drop us completely from the SERP? In other words, we would ideally like our root chiplab.com domain to replace  the subdomain to get us back to where we were before Saturday.  If the removal tool in WMT just removes the link completely, then is the only solution to wait until the site is recrawled and reindexed and hope the root chiplab.com domain ranks in place of the subdomain again?

    Thank you for your time,

    Chase

      Hi Chase,

      Removing dev via web master tools should do the trick for now. Then since google won't get to dev anymore you should be safe.

      Adding both noindex and password protection is not needed. Since it's password protected Google won't get to see the noindex on the pages. So you should only do one of the two. No need to change now. The password protection is safe.

      As expected 'dev.chiplab.com' was removed from the SERP.  Now, I'm a bit worried that the link equity was transferred for good to the subdomain from 'www.chiplab.com'.  That's not possible, right?

      *** Yes, that's not possible so you are good.

      Only 301 redirections are "mandatory" for Google to pass equity - so all good.

        No worries, that's what this community is here for!

        Google views subdomains as different entities. They have different authority metrics and therefore different ranking power. Removing a URL on a subdomain won't have any affect on it's brother over on a different subdomain (for example: dev. and www.).

        Good call to keep the disallow: / on the dev.chiplab.com/robots.txt file - I forgot to mention that you should leave it there, for anti-crawling purpose.

        This is the query you'll want to keep an eye on. The info: operator is new and can be used to show you what Google has indexed as your 'canonical' homepage.

          Hi Logan,

          Last follow-up.  I swear. 🙂

          Since I'm pretty new to this I got scared and cancelled the 'dev.chiplab.com' link removal request.  I did this because I didn't want to go up 14 days without any traffic (this is the estimated time I found that the Google SERP can take to be updated even though we "fetched as GoogleBot in GWT).  May be wrong on the SERP update time?

          So what I did was add a 301 permanent redirect from 'dev.chiplab.com' to 'www.chiplab.com'. I've kept the NOFOLLOW/NOINDEX header on all 'dev' subdomains of course.  I've kept the DISALLOW in robots.txt for the dev.chiplab.com site specifically.  So now I just plan on doing work in the 'dev' site (because I can't test anything with the redirects happening).  And then hopefull in 14 days or so the domain name will change gracefully in the Google SERP from dev.chiplab.com to www.chiplab.com.  I did all of this because of how many sales we would lose if it took 14 days to start ranking again for this term.  Good?

          Best,

          Chase

            You should be all set# I wouldn't worry about link equity, but it certainly wouldn't hurt to keep an eye on your domain authority over the next few days.

              Hi Logan,

              Thanks for fast reply!

              We did the following:

              1. Added NOINDEX on the entire subdomain
              2. Temporarily removed 'dev.chiplab.com' using Google Webmaster Tools
              3. Password protected 'dev.chiplab.com'

              As expected 'dev.chiplab.com' was removed from the SERP.  Now, I'm a bit worried that the link equity was transferred for good to the subdomain from 'www.chiplab.com'.  That's not possible, right?  Do we now just wait until GoogleBot crawls 'www.chiplab.com' and hope that it is restored to #1?

              Thank you for your time (+Shawn, +Matt, +eyqpaq),

              Chase

                noindex would be the easiest way.

                Seen some people having the same issue fixing it by adding rel canonical to dev pointing to the new site and so the main site got back step by step with no interruptions...

                Cheers.

                  Just like Chase said, noindex your dev site to let the search engines know that it should not show in search. I do this on my dev sites everytime.

                    The most ideal method would be to make the dev page password protected. What I would do is to 301 redirect the dev page to the subsequent correct site pages and then when the SERP refreshes, I'd make the dev site a password protected site.

                      Hi Chase,

                      Removing the subdomain within Search Console (WMT) will not remove the rest of your WWW URLs. Since you have different properties in Search Console for each, they are treated separately. That removal is only temporary though.

                      The most sure-fire way to ensure you don't get dev. URLs indexed is to put a NOINDEX tag on that entire subdomain. NOFOLLOW simply means that links on whatever page that tag is on won't be followed by bots.

                      Remember, crawling and indexing are different things. For example, if on your live www. site you had an absolute link somewhere in the mix that had dev.chiplab.com in it, since you presumably haven't nofollowed your live site, a bot will still access that page. The same situation goes for a robots.txt disallow. That only prevents crawling, not indexing. In theory, a bot can get to a disallowed URL and still index it. See this query for an example.

                        Old brand name being suffixed on Google SERP listings

                        At the end of some of our listings in Google search results pages, our old brand name is being suffixed even though it is not in our title tags. For context, we re-branded several months ago, and at that time also migrated to a new domain name. Our title tags have our current brand name suffixed, like "Shop Example Category | Example©". In the Google search results, but not in Bing nor Yahoo, about half of our pages have titles whcih instead look like this: "Shop Example Category | Example© - oldBrandName". The "dash" and the old brand name are not in our title tags, but they are being appended, even when our title tags are fairly long. For example, even with titles at 54 characters (421 pixels), the suffix is being appended. BUT, not with our longer title tags. We are actually OK with the brand name being appended if our title tags are on the shorter side, but would prefer that our current brand name be appended instead of the older one. I realize we could increase the length of all our title tags, and perhaps we may go that route. But, does anyone know where Google would be getting the old brand name to append onto the URLs? We've checked and it is not in our page source (the old brand name is used in our page source in some areas of text and some url paths, but not in any kind of meta tag). Per Google's guidance (https://www.searchenginejournal.com/google-do-not-put-organization-schema-markup-on-every-page/289981/) we only have schema for the "Organization" on our home page, and not on every page. So, assuming this advice is correct to not add schema to every page, how can we inform Google of our current brand name so that it stops appending our old brand name on pages?

                        Can subdomains hurt your primary domain's SEO?

                        Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

                        Should I run my Shopify store on a subdomain or buy a new domain for it?

                        I'm planning to set up a subdomain for my Shopify store but I'm not sure if this is the right approach. Should I purchase a separate domain for it? I'm running Wordpress on my website and want to keep it that way. I want to use Shopify for the ecommerce side. I want to link the store from the top nav and of course I'll use CTA's in a variety of ways to point to merchandise and other things on the store side.   Thanks for any help you can offer.

                        Linking from & to in domains and sub-domains

                        What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

                        How to avoid Google penalties being inherited when moving on with a new domain?

                        Looking for SEOs who have experience with resetting projects by migrating on to a new domain to shed either a manual or algorithmic penalty. My questions are: For algorithmic penalties, what is the best migration strategy to avoid inheriting any kind of baggage? 301, 302, establish no connection between the two sites? For manual penalties, what is the best migration strategy to avoid inheriting any kind of baggage? 301, 302, establish no connection between the two sites? Any other input on these kind of reset projects is appreciated.

                        I have a client who's website is an amalgamation of multiple domains. jacksonhole.net is the main domain but the site passes traffic back and forth from the following domains/sites. My questions is, would it it be better for SEO to consolidate all of these domains under the single high authority domain and 301 redirect the rest or is that a really bad idea?  Thanks for your help. jacksonhole.net (Domain Authority 31) jackson-hole-rental-condos.com (Domain Authority 22) jackson-hole-rental-homes.com (Domain Authority 21) j acksonholehotelguide.com (Domain Authority 19)

                        Hey Moz experts, I had a domain which was really doing better but after the Humming Bird update my traffic was decreased up to 90%. There are plenty of posts on my existing blog, Now what should I do? I mean should I redirect it to a brand new domain or Copy all the posts to a brand new domain and delete my existing domain? Note that the Old domain has PR1, DA 19 and PA 30.

                        Is it safe to 301 redirect old domain to new domain after a manual unnatural links penalty?

                        I have recently taken on a client that has been manually penalised for spammy link building by two previous SEOs. Having just read this excellent discussion, http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience I am weighing up the odds of whether it's better to cut losses and recommend moving domains. I had thought under these circumstances it was important not to 301 the old domain to the new domain but the author (Lewis Sellers) comments on 3/4/13 that he is aware of forwards having been implemented without transferring the penalty to the new domain. http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience#jtc216689 Is it safe to 301? What's the latest thinking?
