      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.

                Hi, Is there any ratio between dofollow and nofollow back-links of a website? Do a website really need some nofollow back-links? Thanks

                If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?

                OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

                301 Redirect of subdomain?

                Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community.  I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them?  I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself.  If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense.  Any thoughts are appreciated.  Thanks for your time.

                Is it better "nofollow" or "follow" links to external social pages?

                Hello, I have four outbound links from my site home page taking users to join us on our social Network pages (Twitter, FB, YT and Google+). if you look at my site home page, you can find those 4 links as 4 large buttons on the right column of the page: http://www.virtualsheetmusic.com/ Here is my question: do you think it is better for me to add the rel="nofollow" directive to those 4 links or allow Google to follow? From a PR prospective, I am sure that would be better to apply the nofollow tag, but I would like Google to understand that we have a presence on those 4 social channels and to make clearly a correlation between our official website and our official social channels (and then to let Google understand that our social channels are legitimate and related to us), but I am afraid the nofollow directive could prevent that. What's the best move in this case? What do you suggest to do? Maybe the nofollow is irrelevant to allow Google to correlate our website to our legitimate social channels, but I am not sure about that. Any suggestions are very welcome. Thank you in advance!

                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

                Use of subdomains, subdirectories or both?

                Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon,  thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C

                Should we stream videos from a subdomain or subfolder?

                This is causing some hand-wrangling and I need some help. Let's say we were developing rich video content for our products and our agency is hosting the content on a new external server. There are already plans to link to these videos from product detail pages, category pages, and landing pages on our main website: www.example.com. Would it be better to create a new subdomain or to use a subfolder with a reverse proxy technique for this video content? It's not truly a microsite and will not have a gallery page to navigate the various videos. For example, would it be better to use this: video.example.com/ ...or this (executed with a reverse proxy😞 www.example.com/video/ Of course, regardless of whether this new content will live on a subdomain or within a subfolder, we plan on creating a video Sitemap using guidance from Justin Hammack in this terrific post.
