      Hi,

      We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain?

      The main domain is vitally important - it is just that sub domain I need to hide.

      Many thanks

        Andy and Alan covered what you need to do. One more thing to keep in mind, check the traffic, you don't want to lose those spot in the SERPS. You might want to consider fixing up the subdomain if it gets you conversions and traffic.

          does the root domain link to the subdomain?

          if so then noindex,follow the pages in the subdomain, this will allow link juice to flow back out of the subdomain.
          any links pointing to a  nofollow page will waste their link juice

            Hi Nicholas,

            You are fine noindexing the subdomain. However, you will need to create a new robots.txt file and place it in the subdomain root for it to work.

            -Andy

              Google Not Indexing Pages (Wordpress)

              google search console indexed urls indexation

              Hello, recently I started noticing that google is not indexing our new pages or our new blog posts. We are simply getting a "Discovered - Currently Not Indexed" message on all new pages. When I click "Request Indexing" is takes a few days, but eventually it does get indexed and is on Google. This is very strange, as our website has been around since the late 90's and the quality of the new content is neither duplicate nor "low quality". We started noticing this happening around February. We also do not have many pages - maybe 500 maximum? I have looked at all the obvious answers (allowing for indexing, etc.), but just can't seem to pinpoint a reason why. Has anyone had this happen recently? It is getting very annoying having to manually go in and request indexing for every page and makes me think there may be some underlying issues with the website that should be fixed.

              How To Cleanup the Google Index After a Website Has Been HACKED

              We have a client whose website was hacked, and some troll created thousands of viagra pages, which were all indexed by Google.  See the screenshot for an example.  The site has been cleaned up completely, but I wanted to know if anyone can weigh in on how we can cleanup the Google index.  Are there extra steps we should take?  So far we have gone into webmaster tools and submitted a new site map. ^802D799E5372F02797BE19290D8987F3E248DCA6656F8D9BF6^pimgpsh_fullsize_distr.png

              How to stop my webmail pages not to be indexed on Google ??

              when i did a search in google for Site:mywebsite.com , for a list of pages indexed. Surprisingly the following come up " Webmail - Login " Although this is associated with the domain , this is a completely different server , this the rackspace email server browser interface  I am sure that there is nothing on the website that links or points to this.
              So why is Google indexing it ? & how do I get it out of there. I tried in webmaster tool but I could not , as it seems like a sub-domain. Any ideas ? Thanks Naresh Sadasivan

              What to do with 302 redirects being indexed

              Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/  (there is no content here, and never has been).  This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting.  Alternatively, I'd say a 301 redirect would be preferable.  But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way?  I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!

              Getting a video displaying a lightbox indexed

              We have created a video for a category page with the goal of building links to the page and improving the conversion rate of visitors to the page.  This category is Christmas oriented so we want to get the video dropped in ASAP. Unfortunately there was a mixup with our developer and he created a lightbox pop-up to display the video on the category page.  I'm concerned this will hurt our ability to get the video indexed in Google. Here was his response.  Is what he says here true? "With the video originally being in lightbox the iFrame Embed was enough since the video can't be on the page, it would have to be hidden on the page which is ignored by Google.  The SEO would be derived from modifying the video sitemap to define the category page as the HTML page for the Wistia video and Google will make the association. The sitemap did all the heavy lifting, the schema markup did not come till later so it had no additional affect on Google other then to re-enforce the sitemap." Thanks for your help!

              Instant Indexing

              I've been  working on a site for a while now, methodically building content and building trust and authority. Lately I've noticed that anything I publish there appears to be instantly indexed by Google, which surprises me. I haven't had this happen before so I'm curious. I'd be interested to hear the experience of others.

              Subdomain and Domain Rankings

              I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league)  when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks

              Root vs. Index.html

              Should I redirect index.html to "/" or vice versa?  Which is better for duplicate content issues?
