      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.

                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?

                Should I Keep adding 301s or use a noindex,follow/canonical or a 404 in this situation?

                Hi Mozzers, I feel I am facing a double edge sword situation. I am in the process of migrating 4 domains into one. I am in the process of creating URL redirect mapping The pages I am having the most issues are the event pages that are past due but carry some value as they generally have one external followed link. www.example.com/event-2008 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2007 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2006 301 redirect to www.newdomain.com/event-2016 Again these old events aren't necessarily important in terms of link equity but do carry some and at the same time keep adding multiple 301s  pointing to the same page may not be a good ideas as it will increase the page speed load time which will affect the new site's performance. If i add a 404 I will lose the bit of equity in those. No index,follow may work since it won't index the old domain nor the page itself but still not 100% sure about it. I am not sure how a canonical would work since it would keep the old domain live. At this point I am not sure which direction I should follow? Thanks for your answers!

                Blog subdomain not redirecting

                Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

                Dev Subdomain Pages Indexed - How to Remove

                I own a website (domain.com) and used the subdomain "dev.domain.com" while adding a new section to the site (as a development link). I forgot to block the dev.domain.com in my robots file, and google indexed all of the dev pages (around 100 of them). I blocked the site (dev.domain.com) in robots, and then proceeded to just delete the entire subdomain altogether. It's been about a week now and I still see the subdomain pages indexed on Google. How do I get these pages removed from Google? Are they causing duplicate content/title issues, or does Google know that it's a development subdomain and it's just taking time for them to recognize that I deleted it already?

                Subdomain for every us state?

I am not sure about is this a good idea? What is your opinion about it?

                Duplicate internal links on page, any benefit to nofollow

                Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!

                NOINDEX or NOINDEX,FOLLOW

                Currently we employ this tag on pages we want to keep out of the index but want link juice to flow through them: <META NAME="ROBOTS" CONTENT="NOINDEX"> Is the tag above the same as: <META NAME="ROBOTS" CONTENT="NOINDEX,FOLLOW"> Or should we be specifying the "FOLLOW" in our tag?
