      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.

                Can subdomains hurt your primary domain's SEO?

                Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

                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?

                Subdomain replaced domain in Google SERP

                Good morning, This is my first post.  I found many Q&As here that mostly answer my question, but just to be sure we do this right I'm hoping the community can take a peak at my thinking below: Problem: We are relevant rank #1 for "custom poker chips" for example. We have this development website on a subdomain (http://dev.chiplab.com).  On Saturday our live 'chiplab.com' main domain was replaced by 'dev.chiplab.com' in the SERP. Expected Cause: We did not add NOFOLLOW to the header tag. We also did not DISALLOW the subdomain in the robots.txt. We could have also put the 'dev.chiplab.com' subdomain behind a password wall. Solution: Add NOFOLLOW header, update robots.txt on subdomain and disallow crawl/index. Question: If we remove the subdomain from Google using WMT, will this drop us completely from the SERP? In other words, we would ideally like our root chiplab.com domain to replace  the subdomain to get us back to where we were before Saturday.  If the removal tool in WMT just removes the link completely, then is the only solution to wait until the site is recrawled and reindexed and hope the root chiplab.com domain ranks in place of the subdomain again? Thank you for your time, Chase

                Complimentary sub-brand; subdomain, subfolder, something else?

                Hello forum! I have a question about subdomains vs. subfolders for a new sub-brand for a company. The company is looking at creating a sub-brand delivering a different service to the parent company. It is complimentary in a sense, but it would need a very different marketing strategy. It is not trying to 'hide' its parent brand at all, but instead would leverage the parent brand as added social proof. I've read that creating a subdomain essentially means starting from scratch in terms of SEO, and that a subfolder would better leverage the domain authority the TLD has accrued. However, creating a subfolder does not really gel with me, as it would not in my opinion provide a good experience for visitors. I.e. it's like running a website that sells electronics and having a subfolder marketing IT support services. Yes, there is some synergy-- but it can also lead to visitor confusion. I'd love your opinions on this! Carlo

                Accidently added a nofollow, noindex tag and then...

                Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod

                How Google treat internal links with rel="nofollow"?

                Today, I was reading about NoFollow on Wikipedia. Following statement is over my head and not able to understand with proper manner. "Google states that their engine takes "nofollow" literally and does not "follow" the link at all. However, experiments conducted by SEOs show conflicting results. These studies reveal that Google does follow the link, but does not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page)." It's all about indexing and ranking for specific keywords for hyperlink text during external links. I aware about that section. It may not generate in relevant result during any keyword on Google web search. But, what about internal links? I have defined rel="nofollow" attribute on too many internal links. I have archive blog post of Randfish with same subject. I read following question over there. Q. Does Google recommend the use of nofollow internally as a positive method for controlling the flow of internal link love? [In 2007] A: Yes – webmasters can feel free to use nofollow internally to help tell Googlebot which pages they want to receive link juice from other pages
                _
                (Matt's precise words were: The nofollow attribute is just a mechanism that gives webmasters the ability to modify PageRank flow at link-level granularity. Plenty of other mechanisms would also work (e.g. a link through a page that is robot.txt'ed out), but nofollow on individual links is simpler for some folks to use. There's no stigma to using nofollow, even on your own internal links; for Google, nofollow'ed links are dropped out of our link graph; we don't even use such links for discovery. By the way, the nofollow meta tag does that same thing, but at a page level.) Matt has given excellent answer on following question. [In 2011] Q: Should internal links use rel="nofollow"?  A:Matt said: "I don't know how to make it more concrete than that." I use nofollow for each internal link that points to an internal page that has the meta name="robots" content="noindex" tag. Why should I waste Googlebot's ressources and those of my server if in the end the target must not be indexed? As far as I can say and since years, this does not cause any problems at all. For internal page anchors (links with the hash mark in front like "#top", the answer is "no", of course. I am still using nofollow attributes on my website. So, what is current trend? Will it require to use nofollow attribute for internal pages?
