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.

Google Pagination Changes
What with Google recently coming out and saying they're basically ignoring paginated pages, I'm considering the link structure of our new, sooner to launch ecommerce site (moving from an old site to a new one with identical URL structure less a few 404s). Currently our new site shows 20 products per page but with this change by Google it means that any products on pages 2, 3 and so on will suffer because google treats it like an entirely separate page as opposed to an extension of the first. The way I see it I have one option: Show every product in each category on page 1. I have Lazy Load installed on our new website so it will only load the screen a user can see and as they scroll down it loads more products, but how will google interpret this? Will Google simply see all 50-300 products per category and give the site a bad page load score because it doesn't know the Lazy Load is in place? Or will it know and account for it? Is there anything I'm missing?

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?

Legacy domains
Hi all, A couple of years ago we amalgamated five separate domains into one, and set up 301 redirects from all the pages on the old domains to their equivalent pages on the new site. We were a bit tardy in using the "change of address" tool in Search Console, but that was done nearly 8 months ago now as well. Two years after implementing all the redirects, the old domains still have significant authority (DAs of between 20-35) and some strong inbound links. I expected to see the DA of the legacy domains taper off during this period and (hopefully!) the DA of the new domain increase. The latter has happened, although not as much as I'd hoped, but the DA of the legacy domains is more or less as good as it ever was? Google is still indexing a handful of links from the legacy sites, strangely even when it is picking up the redirects correctly. So, for example, if you do a site:legacydomain1.com query, it will give a list of results which includes pages where it shows the title and snippet of the page on newdomain.com, but the link is to the page on legacydomain1.com. What has prompted me to finally try and resolve this is that the server which hosted the original 5 domains is now due to be decommissioned which obviously means the 301 redirects for the original pages will no longer be served. I can set up web forwarding for each of the legacy domains at the hosting level, but to maintain the page-by-page redirects I'd have to actually host the websites somewhere. I'd like to know the best way forward both in terms of the redirect issue, and also in terms of the indexing of the legacy domains? Many thanks, Dan

How to recover google rank after changing the domain name?
I just started doing SEO for a new client. The case is a bit unique as they build a new website and for some reason lunched in under another domain name. Old name is foodstepsinasia.com and new one is foodstepsinasiatravel.com OLD one is a respected webites with 35 in MOZ page authority and with +15000 incomming link (104 root domains) NEW one is curently on 0 The programmer has just that build the new website has set it up so that when people write or find the old domain name it redirect to the front page of the new website with the new domain name. this caused that my friends lost a lot of their rankings was so I believ it was a very bad solution. But I also think I can get most of the old rankings back, but my question is what to do now to get as much back of the rankings as fast as possible?? A) I believe I must change the domain name back to foodstepsinasia.com on the new website ? O B) Should I on the old website try finding the url of the pages with most page authority and recreate these urls on the new website or should i redict them to a page with related content? Looking forward to feedback from someone who have experience with similar cases. Thanks!

Buying a domain banned by google
Hi , I came across a super domain for my business but found out that it was a great domain with 100s of link backs but is now banned by Google search engine meaning Google does not index content from that domain. Since the domains linkbacks are from my domin does it make sense to but that domain and redirect those link backs to another (301) and hope that the new domain gets some juice ... I know it is sounding crazy and may not be the best thing to do ethically but still wanted to check if its possible to get some juice.. Rgds Avinash

SEO value in multiple backlinks from same domain and from various sub-domains.
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu

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...
