      Hi,

      I run a hotel booking site and the booking engine is setup on a subdomain.
       The subdomain is disabled from being indexed in robots.txt

      Should the links from the main domain have a nofollow to the subdomain? What are you thoughts?

      Thanks!

        Yeah, internally, "nofollow" still dilutes PageRank, so it doesn't really have a big impact. Practically speaking, I don't think there would be much difference. The links have a customer-facing purposes, I assume, and you just don't want the end result indexed. That should be fine. The only advantage to nofollow might be that it would waste a little less crawl bandwidth (instead of bots visiting the page and then seeing it's blocked, they wouldn't bother). I've tried it both ways in the past (after Google changed the PR-sculpting rules), and could never really measure much difference.

          Thanks for your reply.

          An article I read recently suggested that using nofollow on links on the same website may not be a good idea as "if the website doesn't trust its own pages by having a nofollow, then why would Google want to put trust in it." Does this make sense? Would a subdomain be considered as a completely different site?

          My other concern is using nofollow extensively may raise a flag to Google as a site that is heavily seo optimized or tries to manipulate its linking strategy.

          Any more thoughts? The website is done 100% for users. All I am looking for is the best practice to follow to maximize the seo efforts in this area.

            "diluting your authority by having dofollow links"  I thought it was not possible to link sclupt in this way, I'm I missing something?

            My understanding is that all no follow does is not pass authority and does not help retain authority ( basicly it just throws it out the window the authority it would have passed to that link)

              There is no point diluting your authority by having dofollow links to the subdomain if it isn't going to rank, so by all means "nofollow" the links.

                Subdomain cannibalization

                Hi, I am doing the SEO for a webshop, which has a lot of linking and related websites on the same root domain. So the structure is for example: Root domain: example.com
                Shop: shop.example.com
                Linking websites to shop: courses.example.com, software.example.com,... Do I have to check which keywords these linking websites are already ranking for and choose other keywords for my category and product pages on the webshop? The problem with this could be that the main keywords for the category pages on the webshop are mainly the same as for the other subdomains. The intention is that some people immediately come to the webshop instead of going first to the linking websites and then to the webshop. Thanks.

                How to handle potentially thousands (50k+) of 301 redirects following a major site replacement

                We are looking for the very best way of handling potentially thousands (50k+) of 301 redirects following
                a major site replacement and I mean total replacement. Things you should know
                Existing domain has 17 years history with Google but rankings have suffered over the past year and yes we know why. (and the bitch is we paid a good sized SEO company for that ineffective and destructive work)
                The URL structure of the new site is completely different and SEO friendly URL's rule. This means that there will be many thousands of historical URL's (mainly dynamic ones) that will attract 404 errors as they will not exist anymore. Most are product profile pages and the God Google has indexed them all. There are also many links to them out there.
                The new site is fully SEO optimised and is passing all tests so far - however there is a way to go yet. So here are my thoughts on the possible ways of meeting our need,
                1: Create 301 redirects for each an every page in the .htaccess file that would be one huge .htaccess file 50,000 lines plus - I am worried about effect on site speed.
                2: Create 301 redirects for each and every unused folder, and wildcard the file names, this would be a single redirect for each file in each folder to a single redirect page
                so the 404 issue is overcome but the user doesn't open the precise page they are after.
                3: Write some code to create a hard copy 301 index.php file for each and every folder that is to be replaced.
                4: Write code to create a hard copy 301 .php file for each and every page that is to be replaced.
                5: We could just let the pages all die and list them with Google to advise of their death.
                6: We could have the redirect managed by a database rather than .htaccess or single redirect files. Probably the most challenging thing will be to load the data in the first place, but I assume this could be done programatically - especially if the new URL can be inferred from the old. Many be I am missing another, simpler approach - please discuss

                The Great Subdomain vs. Subfolder Debate, what is the best answer?

                Recently one of my clients was hesitant to move their new store locator pages to a subdomain.  They have some SEO knowledge and cited the whiteboard Friday article at https://moz.com/blog/subdomains-vs-subfolders-rel-canonical-vs-301-how-to-structure-links-optimally-for-seo-whiteboard-friday. While it is very possible that Rand Fiskin has a valid point I felt hesitant to let this be the final verdict.  John Mueller from Google Webmaster Central claims that Google is indifferent towards subdomains vs subfolders. https://www.youtube.com/watch?v=9h1t5fs5VcI#t=50 Also this SEO disagreed with Rand Fiskin’s post about using sub folders instead of sub domains.  He claims that Rand Fiskin ran only 3 experiments over 2 years, while he has tested multiple subdomain vs subfolder experiments over 10 years and observed no difference. http://www.seo-theory.com/2015/02/06/subdomains-vs-subfolders-what-are-the-facts-on-rankings/ Here is another post from the Website Magazine.  They too believe that there is no SEO benefits of a subdomain vs subfolder infrastructure.  Proper SEO and infrastructure is what is most important. http://www.websitemagazine.com/content/blogs/posts/archive/2015/03/10/seo-inquiry-subdomains-subdirectories.aspx Again Rand might be right, but I rather provide a recommendation to my client based on an authoritative source such as a Google engineer like John Mueller. Does anybody else have any thoughts and/or insight about this?

                Franchise sites: Should each franchise have a subdomain or subdirectory?

                One of my clients has about 40 franchisees who are going to have their own sites on a WordPress multisite installation. The question they're wondering: should these be on subdirectories (thesite.com/this-franchise) or on subdomains (this-franchise.thesite.com)? Which is best for SEO? Thanks!

                Subdomain Blog Sitemap link - Add it to regular domain?

                Example of setup:
                www.fancydomain.com
                blog.fancydomain.com Because of certain limitations, I'm told we can't put our blogs at the subdirectory level, so we are hosting our blogs at the subdomain level (blog.fancydomain.com). I've been asked to incorporate the blog's sitemap link on the regular domain, or even in the regular domain's sitemap. 1. Putting the a link to blog.fancydomain.com/sitemap_index.xml in the www.fancydomain.com/sitemap.xml -- isn't this against sitemap.org protocol? 2. Is there even a reason to do this? We do have a link to the blog's home page from the www.fancydomain.com navigation, and the blog is set up with its sitemap and link to the sitemap in the footer. 3. What about just including a text link "Blog Sitemap" (linking to blog.fancydomain.com/sitemap_index.html) in the footer of the www.fancydomain.com (adjacent to the text link "Sitemap" which already exists for the www.fancydomain.com's sitemap. Just trying to make sense of this, and figure out why or if it should be done. Thanks!

                How do I list the subdomains of a domain?

                Hi Mozers, I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information? The only way I could think of doing it is to run a google search on; site:example.com -site:www.example.com The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www). Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information? Cheers, Dan

                Should I 'nofollow' links between my own sites?

                We have five sites which are largely unrelated but for cross-promotional purpose our company wishes to cross link between all our sites, possibly in the footer. I have warned about potential consequences of cross-linking in this way and certainly don't want our sites to be viewed as some sort of 'link ring' if they all link to one another. Just wondering if linking between sites you own really is that much of an issue and whether we should  'nofollow' the links in order to prevent being slapped with any sort of penalty for cross-linking.
