      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

              Keywords are indexed on the home page

              indexation keyword rankings

              Hello everyone, For one of our websites, we have optimized for many keywords. However, it seems that every keyword is indexed on the home page, and thus not ranked properly. This occurs only on one of our many websites. I am wondering if anyone knows the cause of this issue, and how to solve it. Thank you.

              Subdomain or subfolder?

              Hello, We are working on a new site. The idea of the site is to have an ecommerce shop, but the homepage will be a content page, basically a blog page.
              My developer wants to have the blog (home) page on a subdomain, so blog.example.com, because it will be easier to make a nice content page this way, and the the rest of the site will just be on the root domain (example.com). I'm just worried that this will be bad for our SEO efforts. I've always thought it was better to use a sub folder rather than a subdomain. If we get links to the content on the subdomain, will the link juice flow to the shop, on the root domain? What are your thoughts?

              Indexed pages

              Just started a site audit and trying to determine the number of pages on a client site and whether there are more pages being indexed than actually exist. I've used four tools and got four very different answers... Google Search Console: 237 indexed pages Google search using site command: 468 results MOZ site crawl: 1013 unique URLs Screaming Frog: 183 page titles, 187 URIs (note this is a free licence, but should cut off at 500) Can anyone shed any light on why they differ so much? And where lies the truth?

              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

              Fake Links indexing in google

              Hello everyone, I have an interesting situation occurring here, and hoping maybe someone here has seen something of this nature or be able to offer some sort of advice. So, we recently installed a wordpress to a subdomain for our business and have been blogging through it. We added the google webmaster tools meta tag and I've noticed an increase in 404 links. I brought this up to or server admin, and he verified that there were a lot of ip's pinging our server looking for these links that don't exist. We've combed through our server files and nothing seems to be compromised. Today, we noticed that when you do site:ourdomain.com into google the subdomain with wordpress shows hundreds of these fake links, that when you visit them, return a 404 page. Just curious if anyone has seen anything like this, what it may be, how we can stop it, could it negatively impact us in anyway? Should we even worry about it? Here's the link to the google results. https://www.google.com/search?q=site%3Amshowells.com&oq=site%3A&aqs=chrome.0.69i59j69i57j69i58.1905j0j1&sourceid=chrome&es_sm=91&ie=UTF-8 (odd links show up on pages 2-3+)

              Exact match subdomains

              Hi, I have seen significant SEO benefits from owning exact match domains and was wondering whether exact match subdomains hold the same (or some) of these benefits? eg. halloweencostumes.co.uk vs. halloween [dot] costumes.co.uk Many thanks.

              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
