Best way to block a sub-domain from being indexed

Hello,
The search engines have indexed a sub-domain I did not want indexed its on
old.domain.com and dev.domain.com - I was going to password them but is there a best practice way to block them.
My main domain default robots.txt says :-
Sitemap: http://www.domain.com/sitemap.xml
global
User-agent: *
Disallow: /cgi-bin/
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/cache/
Disallow: /wp-content/themes/
Disallow: /trackback/
Disallow: /feed/
Disallow: /comments/
Disallow: /category//
Disallow: */trackback/
Disallow: */feed/
Disallow: /comments/
Disallow: /? -
Hi,
CleverPhD has some interesting ideas with robots.txt and Google Webmaster Tools, but simply password protecting all dev pages should keep pages out of Google's index. There's no best practice here, since a password wall will keep Googlebot out on its own.
To be doubly safe, you can also include a meta noindex tag on dev pages.
Keep in mind that once a page is in Google's index, it's going to take awhile for it to leave (unless you use CleverPhD's method). But, having a blank page in Google's index really isn't all that bad. It's there, but it won't rank for much.
Hope this helps,
Kristina

I've never tried a method like this - FreshFireOne, did you?

First and foremost when you finish all this - password protect your dev instances. A url will leak out eventually and then this happens. I know it is a PIA, but it is worth it.
To remove subdomains. Go into GWT and register the subdomains as separate websites in GWT. Create a robots.txt for each subdomain (not the one you mention, you need a robots that is specific to that subdomain that disallows all files. If you cant do that, have your subdomains include a noindex meta tag on all pages. You have to be careful with this as you do not want to push out your dev. robots.txt or the noindex meta tags to your production server, but it can be done. Talk to your devs. Then go into GWT and use the URL removal tool. Just leave it blank and it will remove the whole site.
Poof. Gone. You can then watch the GWT accounts. They will show errors for the dev site like "Severe health issues are found on your site - Some important page has been removed by request." This is a good error as it confirms that that subdomain is removed.
We actually used this not on a dev site but on our www1 server that was indexed. We use a load balancer with multiple copies of the site. www1 was completing with www. Using this above did the trick.

I am temporarily moving a site to a new domain. Which redirect is best?
A client is having their site redeveloped on a new platform in sections and are moving the sections that are on the new platform to a temporary subdomain until the entire site is migrated. This is happening over the course of 2-3 months. During this time, is it best for the site to use 302 temporary redirects during this time (URL path not changing), or is it best to 301 to the temp. domain, then 301 back to the original once the new platform is completely migrated? Thanks!

Does having a different sub domain for your Landing Page and Blog affect your overall SEO benefits and Ranking?
We have a domain www.spintadigital.com that is hosted with dreamhost and we also have a seperate subdomain blog.spintadigital.com which is hosted in the Ghost platform and we are also using Unbounce landing pages with the sub domain get.spintadigital.com. I wanted to know whether having subdomain like this would affect the traffic metric and ineffect affect the SEO and Rankings of our site. I think it does not affect the increase in domain authority, but in places like similar web i get different traffic metrics for the different domains. As far as i can see in many of the metrics these are considered as seperate websites. We are currently concentrating more on our blogs and wanted to make sure that it does help in the overall domain. We do not have the bandwidth to promote three different websites, and hence need the community's help to understand what is the best option to take this forward.

Indexed non existent pages, problem appeared after we 301d the url/index to the url.
I recently read that if a site has 2 pages that are live such as: http://www.url.com/index and http://www.url.com/ will come up as duplicate if they are both live... I read that it's best to 301 redirect the http://www.url.com/index and http://www.url.com/. I read that this helps avoid duplicate content and keep all the link juice on one page. We did the 301 for one of our clients and we got about 20,000 errors that did not exist. The errors are of pages that are indexed but do not exist on the server. We are assuming that these indexed (nonexistent) pages are somehow linked to the http://www.url.com/index The links are showing 200 OK. We took off the 301 redirect from the http://www.url.com/index page however now we still have 2 exaact pages, www.url.com/index and http://www.url.com/. What is the best way to solve this issue?

Best Way to Consolidate Domains?
Hello, My company has four websites in the same vertical and we're planning to integrate them all on our main company site. So instead of www.siteone.com, www.sitetwo.com, www.sitethree.com, etc. It would be www.branddomain.com/site-one, www.branddomain.com/site-two, etc. I have a few questions... Should we redirect the old domains to the new directories or leave the old domains and stop updating them with new content... Then have the old content, links, etc. 301 to the same content on the new site? Should we literally move all of the content to the new directories? Any tips are appreciated. It's probably pretty obvious that I don't have a ton of technical skills... my development team will be doing the heavy lifting. I just want to be sure we do this correctly from an SEO perspective! Thanks for the help, please let me know if I can clarify anything. E

Merging Domains... Sub-domains, Directories or Seperate Sites?
Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

301 from penalized domain to new domain
I have a client whose site isn't necessarily penalized since they still show for many terms in the SERPS, however at one point they did an xrummer blast of 13,000 links for two anchor texts they were trying to rank for. They have purchased a new domain and have gone white hat and want to 301 some of the old site to the new purely for the users sake so past visitors still find them at t the new location. Will creating 301 redirects pass on to the new domain any bad Karma from the old one in Google's eyes? Thanks for the help.
