Blocking Subdomain from Google Crawl and Index
-
Hey everybody, how is it going?
I have a simple question, that i need answered.
I have a main domain, lets call it domain.com. Recently our company will launch a series of promotions for which we will use cname subdomains, i.e try.domain.com, or buy.domain.com. They will serve a commercial objective, nothing more.
What is the best way to block such domains from being indexed in Google, also from counting as a subdomain from the domain.com. Robots.txt, No-follow, etc?
Hope to hear from you,
Best Regards,

Hello George, Thank you for fast answer! I read that article and there is some issue with that. if you can see at it, i'd really appreciate it. So the problem is that if i do it directly from Tumblr, it will also block it from Tumblr users. Here is the note right below that option "Allow this blog to appear in search results":
"This applies to searches on Tumblr as well as external search engines, like Google or Yahoo."Also, if i do it from GWT, i'm very concerned to remove URLs with my subdomain because i afraid it will remove all my domain. For example, my domain is abc.com and the Tumblr blog is setup on tumblr.abc.com. So i afraid if i remove tumblr.abc.com from index, it will also remove my abc.com. Please let me know what you think.
Thank you!

Hi Marina,
If I understand your question correctly, you just don't want your Tumblr blog to be indexed by Google. In which case these steps will help: http://yourbusiness.azcentral.com/keep-tumblr-off-google-3061.html

Hi guys, I read your conversation. I have similar issue but my situation is slightly different. I'll really appreciate if you can help with this. So i have also a subdomain that i don't want to be indexed by Google. However, that subdomain is not in my control. I mean, i created subdomain on my hosting but it is pointing to my Tumblr blog. So i don't have access to its robot txt. So can anybody advise what can i do in this situation to noindex that subdomain?
Thanks

Personally I wouldn't rely just on robots.txt, as one accidental, public link to any of the pages (easier than you may think!) will result in Google indexing that subdomain page (it just won't be followed). This means that the page can get "stuck" in Google's index and to resolve it you would need to remove it using WMT (instructions here). If there were a lot of pages accidentally indexed, you would need to remove the robots.txt restriction so Google can crawl it, and put a noindex/nofollow tags on the page so Google drops it from its index.
To cut a long story short, I would do both Steps 1 and 2 outlined by Federico if you want to sleep easy at night :).

It would also be smart to add the subdomains in Webmaster Tools in case one does get indexed and you need to remove it.
-
Robots.txt is easiest and quickest way. As a back up you can use the Noindex meta tag on the pages in the subdomain
-
2 ways to do it with different effects:
-
Robots.txt in each subdomain. This will entirely block any search engine to even access those pages, so they won't know what they have inside.
User-Agent:*
Disallow: /
-
noindex tags in those pages. This method allows crawlers to read the page and maybe index (if you set a "follow") the pages to which you link to.or "nofollow" if you don't want the linked pages to be indexed either.
Hope that helps!

Are Wildcard Subdomain Hurting my SEO?
I have some sites with a lot of categories (category, sub-category, sub-subcategory) and locations (country, state/territory, city). To avoid listing pages really deep in my hierarchy I used wildcard subdomains for the locations, but lately I have been told that might be hurting my overall SEO efforts. I have a lot of URLs like https://city-state-country.example.com on one side of the domain and example.com/category/subcategory/subsubcategory on the other. In the middle you see stuff like city-state-country.example.com/category/subcategory/subsubcategory and everything in between. Would I be better off moving the locations to the right side of the domain name? Then you might find stuff like example.com/country/state/city/category/subcategory/subsubcategory and everything in between. I think I could do the new rewrite rules fairly easily since every country slug is just two characters long.

Does Google penalize you for reindexing multiple URLS?

Google Console returning 0 pages as being indexed
HI there, I submitted my site notebuster.net to Search Console over a month ago and it is showing 0 pages as being indexed under the index status report. I know this isn't right as I can see that in google alone by typing in (site:notebusters.net) there are 113 pages indexed. Any idea why this might be? Thanks

How to remove subdomains in a clean way?
Hello, I have a main domain example.com where I have my main content and then I created 3 subdomains one.example.com, two.example.com and three.example.com I think the low ranking of my subdomains is affecting the ranking of my main domain, the one I care the most. So, I decided to get rid of the subdomains. The thing is that only for one.example.com I could transfer the content to my main domain and create 301 redirects. For the other two subdomains I cannot integrate the content in my main domain as it doesn't make sense. Whats the cleanest way to make them dissapear? (just put a redirect to my main domain even if the content is not the same) or just change the robots to "noindex" and put a 404 page in the index of each subdomain. I want to use the way that will harm the least the performance with Google. Regards!

How long does it take for Google to see Changes to a site?
Hi, I have a low PR site (PR 1) that I am starting to work on. Ingeneral when you make changes to my site how long would it take Google to recognize and index those changes? The reason I am wondering is because the site I am working on had a lot of duplicate content (around 700 pages), I got rid of it all, but I wasn't sure how long it would take Google to spider all these pages and re-index them since the site is low PR. Thanks, Ken
