          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

                      Block using your robots.txt page.

                        Should search pages be indexed?

                        Hey guys, I've always believed that search pages should be no-indexed but now I'm wondering if there is an argument to index them? Appreciate any thoughts!

                        Old domain to new domain

                        Hi, A website on server A is no longer required. The owner has redirected some URLS of this website (via plugin) to his new website on server B  -but not all URLS. So when I use COMMAND site:website A , I see a mixture of redirected URLS and not redirected URLS.Therefore two websites are still being indexed in some form and causing duplication. However, weirdly when I crawl with Screaming Frog I only see one URL which is 301 redirected to the new website.  I would have thought I'd see lots of URLs which hadn't been redirected. How come it is different to using the site:command? Anyway, how do I move to the new website completely without the old one being indexed anymore. I thought I knew this but have read so many blogs I've confused myself! Should I: Redirect all URLS via the HTACESS file on old website on server A? There are lots of pages indexed so a lot of URLs. What if I miss some? or Point the old domain via DNS to server B and do the redirects in website B HTaccess file? This seems more sensible but does this method still retain the website rankings? Thanks for any help

                        Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?

                        My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

                        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

                        No Index PDFs

                        Our products have about 4 PDFs a piece, which really inflates our indexed pages. I was wondering if I could add REL=No Index to the PDF's URL? All of the files are on a file server, so they are embedded with links on our product pages. I know I could add a No Follow attribute, but I was wondering if any one knew if the No Index would work the same or if that is even possible. Thanks!

                        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

                        How to change noindex to index?

                        Hey, I've recently upgraded to a pro SEOmoz account and have realised i have 14574 issues to do with 'blocked by meta-robot' and that 'This page is being kept out of the search engine indexes by the meta tag , which may have a value of "noindex", keeping this page out of the index.' How can i change this so my pages get indexed? I read somewhere that i need to change my privacy settings but that thread was 3 years old and now the WP Dashboard has updated.. Please let me know Many thanks, Jamie P.s Im using WordPress 3.5 And i have the XML sitemap plugin And i have no idea where to look for this robots.txt file..

                        Transfer a Main Domain to a Sub-Domain

                        My IT department tells me they want to transfer my main site domain, which has been in existence since 1999 as an e-commerce site (maindomain.com) to a sub-domain (www2.maindomain.com) or a completely new domain (newdomain.net). This is because we are launching a new website and B2C e-commerce engine, but we still have to maintain the legacy B2B e-commerce engine which contains hard-coded URLs, and both systems can't use the same domain. I've been researching the issue across SEOmoz, but I haven't come across this exact type of scenario (mostly I've seen a sub-domain to new domain). I see major problems with their proposal, including negative SEO impact, loss of domain authority/ranking and issues with branding. Does anyone know the exact type of impact I can expect to see in this scenario and specific steps I should go about to minimize the impact? Btw, I will be using Danny Dover's guide on properly moving domains where appropriate. Thanks!
