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

How can you promote a sub-domain ahead of a domain on the SERPs?
I have a new client that wants to promote their subdomain uk.imagemcs.com and have their main domain imagemcs.com fall off the SERPs. Objective? Get uk.imagemcs.com to rank first for UK 'brand' searches. Do a search for 'imagem creative services' and you should see the issue (it looks like rules have been applied to the robots.txt on the main domain to exclude any bots from crawling - but since they've been indexed previously I need to take action as it doesn't look great!). I think I can do this by applying a permanent redirect from the main domain to the subdomain at domain level and then no-indexing the site - and then resubmit the sitemap. My slight concern is that this no-indexing of the main domain may impact on the visibility of the subdomains (I'm dealing with uk.imagemcs.com, but there is us.imagemcs.com and de.imagemcs.com) and was looking for some assurance that this would not be the case. My understanding is that subdomains are completely distinct from domains and as such this action should have no impact on the subdomains. I asked the question on the Webmasters Forum but haven't really got anywhere

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

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

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'?

Shopping Carts & Sub Domains
I was hoping someone could guide me in making the correct decision regarding integrating my existing domain with a hosted shopping cart. I have an existing website to promote my bricks and mortar retail operation and am expanding into web retailing. I will be using one of the major hosted shopping carts. What is the best way to join the two components from an SEO perspective? Have the cart as a sub domain of my main site, or move my existing domain name to be hosted by the cart provider and have both components operate under the same general domain? I have read arguments that putting your cart within a sub domain is not a good idea because any clout of the pre-existing domain will not be shared with the sub domain; that they will be treated as two separate sites. I have also read that using a sub domain is a good idea being that the content focus of the main domain (marketing and blogs) is different form the focus of the sub domain (product sales), and that the two components would benefit form earning their own rankings undiluted by the other. And, I have also read that search engines are getting good at being able to deduce that an eCommerce sub domain is legitimate extension of a content intensive main domain, and that they treat the two components as a combined whole. What is the truth? Which is the better way to go? Any guidance would be appreciated.

Mobile Domain Setup
Hi, If I want to serve a subset of pages on my mobile set from my desktop site or the content is significantly different, i.e. it is not one to one or pages are a summarised version of the desktop, should I use m.site.com or is it still better to use site.com? Many thanks any help appreciated.
