      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.

                Using "nofollow" internally can help with crawl budget?

                Hello everyone. I was reading this article on semrush.com, published the last year, and I'd like to know your thoughts about it: https://www.semrush.com/blog/does-google-crawl-relnofollow-at-all/ Is that really the case? I thought that Google crawls and "follows" nofollowed tagged links even though doesn't pass any PR to the destination link. If instead Google really doesn't crawl internal links tagged as "nofollow", can that really help with crawl budget?

                Can using nofollow on magento layered navigation hurt?

                Howdy Mozzers! We would like to use no follow, no index on our magento layered navigation pages after any two filters are selected. (We are using single filter pages as landing page, so we would liked them indexed) Is it ok to use nofollow, noindex on these filter pages? Are there disadvantages of using nofollow on internal pages? Matt mentioned refraining from using nofollow internally https://www.youtube.com/watch?v=4SAPUx4Beh8 But we would like to conserve crawling bandwidth and PR flow on potentially 100's of thousands of irrelevant/duplicate filter pages.

                Using subdomains for related landing pages?

                Seeking subdomain usage and related SEO advice...  I'd like to use multiple subdomains for multiple landing pages all with content related to the main root domain. Why?...Cost: so I only have to register one domain. One root domain for better 'branding'. Multiple subdomains that each focus on one specific reason & set of specific keywords people would search a solution to their reason to hire us (or our competition).

                Merging two different domains - subdomain or subfolder?

                My company has two sites on different domains. We are considering merging the sites into one and keeping only the dominant domain. The dominate site is already a sub-domain of a larger organization so the new sub-domain would be two levels deep.  I realize this is a little abstract so below is an example Dominant company site:       company.root-domain.com Secondary company site:     other-root-domain.com When they merge, everything will be on company.root-domain.com. Should it be other.company.root-domain.com   or company.root-domain.com/other Note: The other site has several hundred pages. Both sites have strong authority and link profiles. I want to maintain as much of the value on the other site as possible with the merge.

                Turning off a subdomain

                Hi! I'm currently working with http://www.muchbetteradventures.com/. They have a previous version of the site, http://v1.muchbetteradventures.com, as sub domain on their site. I've noticed a whole bunch of indexing issues which I think are caused by this. The v1 site has several thousand pages and ranks organically for a number of terms, but the pages are not relevant for the business at this time. The main site has just over 100 pages. More than 28,400 urls are currently indexed. We are considering turning off the v1 site and noindexing it. There are no real backlinks to it. The only worry is that by removing it, it will be seen as a massive drop in content. Rankings for the main site are currently quite poor, despite good content, a decent link profile and high domain authority. Any thoughts would be much appreciated!

                Google is mixing subdomains. What can we do?

                Hi! I'm experiencing something that's kind of strange for me. I have my main domain let's say: www.domain.com. Then I have my mobile version in a subdomain: mobile.domain.com and I also have a german version of the website de.domain.com. When I Google my domain I have the main result linking to: www.domain.com but then Google mixes all the domains in the sites links. For example a Sing in may be linking mobile.domain.com, a How it works link may be pointing to de.domain.com, etc What's the solution? I think this is hurting a lot my position cause google sees that all are the same domain when clearly is not. thanks!!

                Noindex, Nofollow to previous domain

                Hi, My programmer recently did a horrible mistkae by adding noindex, nofollow to our website without me noticing for two days. At the same time he did it we bought a new domain and redirected the old domain to the new domain: The Old domain is: http://www.websitebuildersworld.com and the new one is: http://www.websiteplanet.com Now unfortunatly I didn't notice the noindex,nofollow when it was on the old domain and I redirected it to websiteplanet.com before I fixed the noindex, nofollow. I fixed the problem around 10 hours ago on the new domain (www.websiteplanet.com) but the old domain didn't get indexed back (yet), so for example if you search for WebsiteBuildersWorld in google you will not reach the homepage as google deleted it because of the noindex,nofollow. My question is:
                Do you think that it will be fixed and google will retrieve websitebuildersworld homepage to his search results and then redirect it to websiteplanet? Or because I redirected websitebuildersworld.com to websiteplanet.com before letting google crawling websitebuildersworld.com without the noindex,no follow it wouldn't get indexed again? I hope I explained the problem good enough. Looking forward for your valuable replies. Thanks.

                Block an entire subdomain with robots.txt?

                Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
