      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/

        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.

              Best way to "Prune" bad content from large sites?

              I am in process of pruning my sites for low quality/thin content. The issue is that I have multiple sites with 40k + pages and need a more efficient way of finding the low quality content than looking at each page individually. Is there an ideal way to find the pages that are worth no indexing that will speed up the process but not potentially harm any valuable pages? Current plan of action is to pull data from analytics and if the url hasn't brought any traffic in the last 12 months then it is safe to assume it is a page that is not beneficial to the site. My concern is that some of these pages might have links pointing to them and I want to make sure we don't lose that link juice. But, assuming we just no index the pages we should still have the authority pass along...and in theory, the pages that haven't brought any traffic to the site in a year probably don't have much authority to begin with. Recommendations on best way to prune content on sites with hundreds of thousands of pages efficiently?  Also, is there a benefit to no indexing the pages vs deleting them? What is the preferred method, and why?

              What are the best practices for geo-targeting by sub-folders?

              My domain is currently targeting the US, but I'm building out sub-folders that will need to geo-target France, England, and Spain. Each country will have it's own sub-folder, and professionally translated (domain.com/france). Other than the hreflang tags, what are other best practices I can implement? Can Google Webmaster tools geo-target by subfolder? Any suggestions would be appreciated. Thanks Justin

              Consolidating Multiple Domains into A Single Domain

              I have a client who's website is an amalgamation of multiple domains. jacksonhole.net is the main domain but the site passes traffic back and forth from the following domains/sites. My questions is, would it it be better for SEO to consolidate all of these domains under the single high authority domain and 301 redirect the rest or is that a really bad idea?  Thanks for your help. jacksonhole.net (Domain Authority 31) jackson-hole-rental-condos.com (Domain Authority 22) jackson-hole-rental-homes.com (Domain Authority 21) j acksonholehotelguide.com (Domain Authority 19)

              Best way to remove full demo (staging server) website from Google index

              I've recently taken over an in-house role at a property auction company, they have a main site on the top-level domain (TLD) and 400+ agency sub domains! company.com agency1.company.com agency2.company.com... I recently found that the web development team have a demo domain per site, which is found on a subdomain of the original domain - mirroring the site. The problem is that they have all been found and indexed by Google: demo.company.com demo.agency1.company.com demo.agency2.company.com... Obviously this is a problem as it is duplicate content and so on, so my question is... what is the best way to remove the demo domain / sub domains from Google's index? We are taking action to add a noindex tag into the header (of all pages) on the individual domains but this isn't going to get it removed any time soon! Or is it? I was also going to add a robots.txt file into the root of each domain, just as a precaution! Within this file I had intended to disallow all. The final course of action (which I'm holding off in the hope someone comes up with a better solution) is to add each demo domain / sub domain into Google Webmaster and remove the URLs individually. Or would it be better to go down the canonical route?

              Is there a way to get a list of Total Indexed pages from Google Webmaster Tools?

              I'm doing a detailed analysis of how Google sees and indexes our website and we have found that there are 240,256 pages in the index which is way too many. It's an e-commerce site that needs some tidying up. I'm working with an SEO specialist to set up URL parameters and put information in to the robots.txt file so the excess pages aren't indexed (we shouldn't have any more than around 3,00 - 4,000 pages) but we're struggling to find a way to get a list of these 240,256 pages as it would be helpful information in deciding what to put in the robots.txt file and which URL's we should ask Google to remove. Is there a way to get a list of the URL's indexed? We can't find it in the Google Webmaster Tools.

              Best way to noindex an image?

              Hi all, A client wanted a few pages noindexed, which was no problem using the meta robots noindex tag. However they now want associated images removed, some of which still appear on pages that they still want indexed. I added the images to their robots.txt file a few weeks ago (probably over a month ago actually) but they're all still showing when you do an image search. What's the best way to noindex them for good, and how do I go about implementing it? Many thanks, Steve

              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?

              Can a XML sitemap index point to other sitemaps indexes?

              We have a massive site that is having some issue being fully crawled due to some of our site architecture and linking. Is it possible to have a XML sitemap index point to other sitemap indexes rather than standalone XML sitemaps? Has anyone done this successfully? Based upon the description here: http://sitemaps.org/protocol.php#index it seems like it should be possible. Thanks in advance for your help!
