      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.

                Why does Moz recommend subdomains for language-specific websites?

                In Moz's domain recommendations, they recommend subdirectories instead of subdomains (which agrees with my experience), but make an exception for language-specific websites: Since search engines keep different metrics for domains than they do subdomains, it is recommended that webmasters place link-worthy content like blogs in subfolders rather than subdomains. (i.e. www.example.com/blog/ rather than blog.example.com) The notable exceptions to this are language-specific websites. (i.e., en.example.com for the English version of the website). Why are language-specific websites excepted from this advice? Why are subdomains preferable for language-specific websites? Google's advice says subdirectories are fine for language-specific websites, and GSC allows geographic settings at the subdirectory level (which may or may not even be needed, since language-specific sites may not be geographic-specific), so I'm unsure why Moz would suggest using subdirectories in this case.

                Nofollow Outbound Links on Listings from Travel Sites?

                We oversee a variety of regional, county, and town level tourism websites, each with hundreds (or even thousands) of places/businesses represented with individual pages. Each page contains a link back to the place's main web presence if available. My fear is that a large portion of these linked to sites are low quality, and may even be spammy. With our budgets there is no way to sort through them and assign nofollows as needed. There are also a number of broken links that we try to stay on top of but at times some slip through due to the sheer number of pages. I am thinking about adding a nofollow to these outbound links across the board. This would not be all outbound links on the website, just the website links on the listing pages. I would love to know peoples thoughts on this.

                Internal Links - Dofollow or Nofollow and why?

                Hey there Mozzers, I am a question about internal links. If I am writing a article about something and want to link to another one of my articles inside my blog, do i have to make that link nofollow or dofollow? If possible tell me why also. Thanks in advance

                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.

                Is this link follow or nofollow? Does it pass linkjuice?

                I have been seeing conflicting opinions about how Google would treat links using 'onclick'. For the example provided below: Would Google follow this link and pass the appropriate linking metrics(it is internal and points to a deeper level in our visnav)? =-=-=-=-=-=-= <div id='<a class="attribute-value">navBoxContainer</a>' class="<a class="attribute-value">textClass</a>"> <div id="<a class="attribute-value">boxTitle</a>" onclick="<a class="attribute-value">location.href='bla</a>h.example.com"> <div class="<a class="attribute-value">boxTitleContent</a>" title="<a class="attribute-value">Text Here</a>"><a href<a class="attribute-value">Text Here</a>"><a ="blah.exam.cpleom">Text Herea>div> ``` =-=-=-=-=-=-= An simple yes/no would be alright, but any detail/explination you could provide would be helpful and very much appreciated. Thank you all for your time and responses.

                PDFs and images in Sub folder or subdomain?

                What would you recommend as best practice? Our ecommerce site has a lot of PDFs supporting the product page. Currently they are kept in a sub domain and so are all images. Would it be better to keep them all in a subfolder? I've read about blogs being hosted on a subfolder to be better than subdomain but what about pdfs and images? thoughts?

                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.
