Follow or nofollow to subdomain
-
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.txtShould 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.

Should I set up no index no follow on low quality pages?
I know it is a good idea for duplicate pages, blog tags, etc. but I remember somewhere that you can help the overall link juice of a website by adding no index no follow or no index follow low quality content pages of your website. Is it still a good idea to do this or was it never a good idea to begin with? Michael

How to handle a blog subdomain on the main sitemap and robots file?
Hi, I have some confusion about how our blog subdomain is handled in our sitemap. We have our main website, example.com, and our blog, blog.example.com. Should we list the blog subdomain URL in our main sitemap? In other words, is listing a subdomain allowed in the root sitemap? What does the final structure look like in terms of the sitemap and robots file? Specifically: **example.com/sitemap.xml ** would I include a link to our blog subdomain (blog.example.com)? example.com/robots.xml would I include a link to BOTH our main sitemap and blog sitemap? blog.example.com/sitemap.xml would I include a link to our main website URL (even though it's not a subdomain)? blog.example.com/robots.xml does a subdomain need its own robots file? I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it. I appreciate your help with this.

Disavowin a sitewide link that has Thousands of subdomains. What do we tell Google?
Hello, I have a hosting company that partnered up with a blogger template developer that allowed users to download blog templates and have my footer links placed sitewide on their website. Sitewides i know are frowned upon and that's why i went through the rigorous Link Audit months ago and emailed every webmaster who made "WEBSITENAME.Blogspot.com" 3 times each to remove the links. I'm at a point where i have 1000 sub users left that use the domain name of "blogspot.com". I used to have 3,000! Question: When i disavow these links in Webmaster tools for Google and Bing, should i upload all 1000 subdomains of "blogspot.com" individually and show Google proof that i emailed all of them individually, or is it wise to just include just 1 domain name (www.blogspot.com) so Google sees just ONE big mistake instead of 1000. This has been on my mind for a year now and I'm open to hearing your intelligent responses.

Archiving a festival website - subdomain or directory?
Hi guys I look after a festival website whose program changes year in and year out. There are a handful of mainstay events in the festival which remain each year, but there are a bunch of other events which change each year around the mainstay programming.This often results in us redoing the website each year (a frustrating experience indeed!) We don't archive our past festivals online, but I'd like to start doing so for a number of reasons 1. These past festivals have historical value - they happened, and they contribute to telling the story of the festival over the years. They can also be used as useful windows into the upcoming festival. 2. The old events (while no longer running) often get many social shares, high quality links and in some instances still drive traffic. We try out best to 301 redirect these high value pages to the new festival website, but it's not always possible to find a similar alternative (so these redirects often go to the homepage) Anyway, I've noticed some festivals archive their content into a subdirectory - i.e. www.event.com/2012 However, I'm thinking it would actually be easier for my team to archive via a subdomain like 2012.event.com - and always use the www.event.com URL for the current year's event. I'm thinking universally redirecting the content would be easier, as would cloning the site / database etc. My question is - is one approach (i.e. directory vs. subdomain) better than the other? Do I need to be mindful of using a subdomain for archival purposes? Hope this all makes sense. Many thanks!

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.
