      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

            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.

              SEO implications of moving fra a sub-folder to a root domain

              I am considering a restructure of my site, and was hoping for some input on SEO implications which I am having some issues getting clarity in. (I will be using sample domains/urls because of language reasons, not an english site), Thinking about moving a site (all content) from example.com/parenting -> parenting.com. This is to have a site fully devoted to this theme, and more easily monitor and improve SEO performance on this content alone. Today all stats on external links, DA etc is related to the root domain, and not just this sub-department. Plus it would be a better brand-experience of the content and site. Other info/issues: -The domain parenting.com (used as example) is currently redirected to example.com/parenting. So I would have to reverse that redirect, and would also redirect all articles to the new site. The current domain example.com has a high DA (67), but the new domain parenting.com has a much lower DA  (24). Question: Would the parenting.com domain improve it's DA when not redirected and the sub-folder on the high-DA domain is redirected here instead? Would it severly hurt SEO traffic to make this change, and if so is there a strategy to make the move with as little loss in traffic as possible? How much value is in having a stand-alone domain, which also is one of the most important keywords for this theme? My doubt comes mostly from moving from a domain with high DA to a domain with much lower DA, and I am not sure about how removing the redirect would change that, or if placing a new redirect from the subfolder on the current site would help improve it. Would some DA flow over with a 301 redirect? Thanks for any advice or hints to other documentation that might be of interest for this scenario 🙂

              Sub Domain Usage

              I see that the gap uses gap.com, oldnavy.gap.com and bananarepublic.gap.com.  Wouldn't a better approach for SEO to have oldnavy.com, bananarepublic.com and gap.com all separate?  Is there any benefit to using the approach of store1.parentcompany.com, store2.parentcompany.com etc?  What are the pros and cons to each?

              What's the best way to redirect categories & paginated pages on a blog?

              I'm currently re-doing my blog and have a few categories that I'm getting rid of for housecleaning purposes and crawl efficiency. Each of these categories has many pages (some have hundreds). The new blog will also not have new relevant categories to redirect them to (1 or 2 may work). So what is the best place to properly redirect these pages to? And how do I handle the paginated URLs? The only logical place I can think of would be to redirect them to the homepage of the blog, but since there are so many pages, I don't know if that's the best idea. Does anybody have any thoughts?

              Is it safe to redirect our .nl (netherlands) domain that we have just purchased to our .com domain?

              Hi all! We've recently developed a German version of our website with German translation and now we have just purchased a .nl domain, but with this one, we want all of the copy to remain in English. Is it ok to redirect our .nl domain to our current .com website or will this give us bad SEO points? Thank you!

              Best way to permanently remove URLs from the Google index?

              We have several subdomains we use for testing applications. Even if we block with robots.txt, these subdomains still appear to get indexed (though they show as blocked by robots.txt. I've claimed these subdomains and requested permanent removal, but it appears that after a certain time period (6 months)? Google will re-index (and mark them as blocked by robots.txt). What is the best way to permanently remove these from the index? We can't use login to block because our clients want to be able to view these applications without needing to login. What is the next best solution?

              What is the best way to optimize/setup a teaser "coming soon" page for a new product launch?

              Within the context of a physical product launch what are some ideas around creating a /coming-soon page that "teases" the launch. Ideally I'd like to optimize a page around the product, but the client wants to try build consumer anticipation without giving too many details away. Any thoughts?

              Best way to block a search engine from crawling a link?

              If we have one page on our site that is is only linked to by one other page, what is the best way to block crawler access to that page? I know we could set the link to "nofollow" and that would prevent the crawler from passing any authority, and we can set the page to "noindex" to prevent it from appearing in search results, but what is the best way to prevent the crawler from accessing that one link?
