Block a sub-domain from being indexed
-
This is a pretty quick and simple (i'm hoping) question. What is the best way to completely block a sub domain from getting indexed from all search engines?
One item i cannot use is the meta "no follow" tag.
Thanks! - Kyle

Keep in mind that Google Index's everything that it can crawl. Even if you put a block in the robots.txt they will probably crawl it. You can require a password to that subdomain and keep big G out. This is easy to do if you have a site with cpanel access. Just go to manage permissions, and password protect that director with a .htaccess pw.
-
The robots.txt file just tells the bots you would "prefer" they don't index but there is nothing to prevent them from indexing.The only sure way to do this is to restrict access to the sub-domain for everyone and require some sort of authentication. If they don't have access they can't index.
-
In subdomain.example.com/robots.txt add the statements:
User-agent: *
Disallow: /Warning: Be absolutely certain that the above statements are not included in your example.com/robots.txt file or you'll kill your site.
-
Each subdomain may have its own robots.txt file. So for that subdomain, you can put:
User-agent: * Disallow: /In the robots.txt, and that should do it.
Please note that disallowing pages in robots.txt will not necessarily mean they won't appear on search result pages.... if people link to pages that are disallowed on that subdomain, they can still appear in SERPs. I had this happen with a few pages, which leads to funny listings in the SERPs because Google has to guess what the page title and description of the page should be, since it's not allowed to read the page. The meta noindex tag is the way to go if you want to be really sure the page doesn't appear in the SERPs. If you use that, don't disallow the page. Here's a recent SEOMoz post about it: http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts

That was going to be my assumption but i wasn't 100% sure how they worked with sub domains. Are you able to supply a little more information on implementation? It is extremely important that it only blocks: sub.domain.com and not domain.com

Does having a sub-domain on a different server affect SEO?
I'm working with a company that has a hard-coded website on the root domain, and then a WordPress blog on a subdomain on a separate server. We're planning on implementing a hub and spoke model for their content, hosting the main hubs on the root domain and the linked articles on the blog. Is having the blog on a different server going to hinder our SEO efforts?

URLs dropping from index (Crawled, currently not indexed)
I've noticed that some of our URLs have recently dropped completely out of Google's index. When carrying out a URL inspection in GSC, it comes up with 'Crawled, currently not indexed'. Strangely, I've also noticed that under referring page it says 'None detected', which is definitely not the case. I wonder if it could be something to do with the following? https://www.seroundtable.com/google-ranking-index-drop-30192.html - It seems to be a bug affecting quite a few people. Here are a few examples of the URLs that have gone missing: https://www.ihasco.co.uk/courses/detail/sexual-harassment-awareness-training https://www.ihasco.co.uk/courses/detail/conflict-resolution-training https://www.ihasco.co.uk/courses/detail/prevent-duty-training Any help here would be massively appreciated!

Removing a site from Google index with no index met tags
Hi there! I wanted to remove a duplicated site from the google index. I've read that you can do this by removing the URL from Google Search console and, although I can't find it in Google Search console, Google keeps on showing the site on SERPs. So I wanted to add a "no index" meta tag to the code of the site however I've only found out how to do this for individual pages, can you do the same for a entire site? How can I do it? Thank you for your help in advance! L

Multilingual Website - Sub-domain VS Sub-directory
Hi Folks - Need your advice on the pros and cons of going with a sub-domain vs a sub-directory approach for a multi lingual website. The best would be a ccTLD but that is not possible now, so I would be more interested in knowing your take on these 2 options. Though, I have gone through http://www.stateofsearch.com/international-multilingual-sites-criteria-to-establish-seo-friendly-structure/ and this somewhat vouches for a sub-directory, but what would you say'?

Umlaut in domain
Hi, My client wants to expand it's business to Germany and logically we need a domain name to match. We've found a great one and regsiterd several variants to it. However I just found out that in Germany it is possible (while here it's not) to register a domain with an umlaut. My question is: will google assign more value to: schädlinge.de than schadlinge.de when users search for schädlinge? If yes, how large will the difference be? (I will use an umlaut in the title etc) Kind regards,

What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
Technical SEO | | fthead9
User-agent: *
Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.0 -
Using hyphenated sub-domains or non-hyphenated sub-domains? What is the question! I Any takers?
For our corporate business level domain, we are exploring using a hyphenated sub-domain foir a project. Something like www.go-figure.extreme.com I thought from a user perspective it seems cluttered. The domain length might also be an issue with the new Algorithm big G has launched in recent past. I know with past experience, hyphenated domains usually take longer to index, as they are used by spammers more frequently and can take longer to get out of the supplementary index. Our company site has over 90 million viewers / year, so our brand is well established and traffic isn't an issue. This is for a corporate level project and I didn't have the answer! Will this work? anyone have any experience testing this. Any thoughts will help! Thanks, Rob

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
