Subdomain replaced domain in Google SERP
-
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:
- Added NOINDEX on the entire subdomain
- Temporarily removed 'dev.chiplab.com' using Google Webmaster Tools
- 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),

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.

When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?
We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains? Also if you could provide any sources of information that specify this, I can't see to find anything!

Cleaning up a Spammy Domain VS Starting Fresh with a New Domain
Hi- Can you give me your opinion please... if you look at murrayroofing.com and see the high SPAM score- and the fact that our domain has been put on some spammy sites over the years- Is it better and faster to place higher in google SERP if we create a fresh new domain? My theory is we will spin our wheels trying to get unlisted from alot of those spammy linking sites. And that it would be faster to see results using a fresh new domain rather than trying to clean up the current spammy doamin. Thanks in advance - You guys have been awesome!!

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Consolidating Multiple Domains into A Single Domain
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)

Referring domain issues
Our website (blahblah).org has 32 other domains pointing to it all from the same I.P address. These domains including the one in question, were all purchased by the website owner, who has inadvertently created duplicate content and on most of these domains. Some of these referring domains have 301's, some don't - but it appears they have all been de-indexed by Google. I'm somewhat out of my depth here (most of what I've said above has come from an agency who said we should address this before being slapped by Google). However I need to explain to my line manage the actual issues in more detail and the repercussions - any anyone please offer advice please? I'm happy to use the agency, or another - but would like some second opinions if possible?

Other domains hosted on same server showing up in SERP for 1st site's keywords
For the website in question, the first domain alphabetically on the shared hosting space, strange search results are appearing on the SERP for keywords associated with the site. Here is an example: A search for "unique company name" shows the results: www.uniquecompanyname.com as the top result. But on pages 2 and 3, we are getting results for the same content but for domains hosted on the same server. Here are some examples with the domain name replaced: UNIQUE DOMAIN NAME PAGE TITLE

How to clean up a SERP?
I have a new customer and he wants me to clear up the SERP for his branded keyword, the SERP currently has his site and two other sites related to him under his result... Under that is bad reviews and old reports. My client does own the top spot (#1) for his branded name. My client has a: linkedin facebook twitter myspace I was thinking to push all these to the first page, this will clear up some of those bad reviews. What are your thoughts? Have any of you ever had this type of case? I need to get 6 different sites to all rank for the same exact key term, however I have the top spot to link from...
