      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

              Not all images indexed in Google

              Hi all, Recently, got an unusual issue with images in Google index. We have more than 1,500 images in our sitemap, but according to Search Console only 273 of those are indexed. If I check Google image search directly, I find more images in index, but still not all of them. For example this post has 28 images and only 17 are indexed in Google image. This is happening to other posts as well. Checked all possible reasons (missing alt, image as background, file size, fetch and render in Search Console), but none of these are relevant in our case. So, everything looks fine, but not all images are in index. Any ideas on this issue? Your feedback is much appreciated, thanks

              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!

              Robots.txt on subdomains

              Hi guys! I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?

              How to determine which pages are not indexed

              Is there a way to determine which pages of a website are not being indexed by the search engines? I know Google Webmasters has a sitemap area where it tells you how many urls have been submitted and how many are indexed out of those submitted. However, it doesn't necessarily show which urls aren't being indexed.

              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!

              Index.php and 301 redirect with Joomla

              Hi, I'm running Joomla 1.7 with SEF on and I'm trying to do a htaccess redirect which fails. I have approximately 100 in effect so far and all working fine, but I have one snag. Index.php is not working as I need it to when it's redirected to www.myurl.com/ If I turn on index.php redirect to root using this code #index.php to root
              RewriteCond %{HTTP_HOST} ^myurl.com$ [OR]
              RewriteCond %{HTTP_HOST} ^www.myurl.com$
              RewriteRule ^index.php$ "http://www.myurl.com/" [R=301,L] And then go to www.myurl.com/test.html I'm redirected to the homepage. I think this is because all pages are index.php in joomla. SEOMOZ and Google both think that index.php and root are duplicate pages. Does anyone have any advice for overcoming this? Thanks, Adam

              How to get Google to index another page

              Hi, I will try to make my question clear, although it is a bit complex. For my site the most important keyword is "Insurance" or at least the danish variation of this. My problem is that Google are'nt indexing my frontpage on this, but are indexing a subpage - www.mydomain.dk/insurance instead of www.mydomain.dk. My link bulding will be to subpages and to my main domain, but i wont be able to get that many links to www.mydomain.dk/insurance. So im interested in making my frontpage the page that is my main page for the keyword insurance, but without just blowing the traffic im getting from the subpage at the moment. Is there any solutions to do this? Thanks in advance.
