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

Google is still indexing the old domain a year after 301 redirects are put in place
Hi there, You might have experienced this before but for me this is the first. A client of mine moved from domain A (www.domainA.com) to domain B (www.domainB.com). 301 redirects are all in place for over a year. But the old domain is still showing in Google when you search for "site:domainA.com" The HTTP Header check shows this result for the URL https://www.domainA.com/company/cookie-policy.aspx HTTP/1.1 301 Moved Permanently =>

Connection => close Does the redirect look wrong? The change of address request was made on Google Console when the website was moved over a year ago. Edit: Checked the domainA.com on bing and it seems that its not indexed, and replaced with domainB.com, which is the right. Just Google is indexing the old domain! Please let me know your thoughts on why this is happening. Best,0 -
Forwarding a .org domain to a .com domain: any negative impact to consider?
Hello! I have a question I've been unable to find a clear answer to. My client's primary domain is a .com with a satisfactorily high DA. My client owns the .org version of its domain (which has a very low DA, I suppose due to inactivity) but has never forwarded it on. For branding/visibility/traffic reasons, I'd like to recommend they set up the .org domain to forward to the .com domain, but I wanted to ask a few questions first: 1. Does forwarding low-value DA domains to high-value DA domains have any negative authority/SEO impact? 2. If the .org domain was to be forwarded, am I correct that an SSL cert is not necessary for it if the .com domain has an SSL cert? Thanks in advance!

Should a sub domain be a separate property in the Search Console?
We're launching a blog on a sub-domain of a corp site (blog.corpsite.com). We already have corpsite.com set up in the Search Console. Should I set up a separate property for this sub-domain in the Search Console (WMT) in order to manage it? Is it necessary? Thanks, JM

Block Domain in robots.txt
Hi. We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off... Any ideas why this could be and whether it's normal? I can send you more domain infos by personal message if you want to have a look at it.

What to do with 302 redirects being indexed
Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/ (there is no content here, and never has been). This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting. Alternatively, I'd say a 301 redirect would be preferable. But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way? I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!

How to block "print" pages from indexing
I have a fairly large FAQ section and every article has a "print" button. Unfortunately, this is creating a page for every article which is muddying up the index - especially on my own site using Google Custom Search. Can you recommend a way to block this from happening? Example Article: http://www.knottyboy.com/lore/idx.php/11/183/Maintenance-of-Mature-Locks-6-months-/article/How-do-I-get-sand-out-of-my-dreads.html Example "Print" page: http://www.knottyboy.com/lore/article.php?id=052&action=print

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.
