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.

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.
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?
-
I think Mueller's main point may be that if you treat your subdomains separately from your main site, Google will treat them differently as well. For example, if you have three subdomains - www, blog and cloud - but all of them have different navigation, css and limited interlinking and little keyword theme commonality, Google will treat them as separate sites and you will suffer the dreaded subdomain issue.
BUT if you integrate the three domains well - same nav, same look & feel and lots of good contextual anchor text interlinking, Google will treat it as the same site and the subdomain issue will become moot.
Has anyone done any testing with those variables?
-
Yup! All the case studies I showed above (and plenty since) have demonstrated that you can boost traffic by moving from the subdomain to a subfolder.
-
Great thread! What about a situation where a blog already sits on a subdomain (bearing in mind it hasn't been driving a significant amount of traffic as the site is fairly new). My recommendation would be to move to subfolder, would you agree?
Thank you!

This is my new favorite quote... "I understand that Google's representatives have the authority of working at Google going for them, but I also believe they're wrong." (Rand Fishkin)

Greetings All,
So the debate goes on and I personally think the value of subfolders versus directories certainly makes sense especially from a linking, age and juice perspective. I do notice in most articles they talk about the benefits for subfolders as it relates to blogs. In past tests and studies, you have shed any insight into how this may affect ecommerce as it relates to countries.
We currently have each country on a subdomain and can run it through webmaster tools and geotarget the country however are considering switching to subfolders, based on all the articles we've read. This would in such drive many more links back to each new subfolder assuming the majority of our links are from "www". It would seem to make sense to switch to subfolders and would be especially helpful as new sub-folders were launched.
I was just wondering if the same argument can be made when it comes to ecommerce and country specific sites. Each site (currently different subdomains) uses a different language and currency. Meta and content is different for each. We launched "www" over 15 years ago but in the past 2 years have introduced various subdomains (ie new languages). As we enter into new countries, we are considering switching everything over to subfolders (obviously with 301'ing the subdomains over to the new subfolders so we dont lose all our existing links).
Im assuming since your studies indicate, you'd think this to be a good idea however all the talk has not been so much about countries and ecommerce. Any one have any light or information they can share with regards to the topic??

Hi Rosemary - thankfully, I have data, not just opinions to back up my arguments:
- In 2014, Moz moved our Beginner's Guide to SEO from guides.moz.com to moz.com itself. Rankings rose immediately, with no other changes. We ranked higher not only for "seo guide" (outranking Google themselves) but also for "beginners guide" a very broad phrase.
- Check out https://iwantmyname.com/blog/2015/01/seo-penalties-of-moving-our-blog-to-a-subdomain.html - goes into very clear detail about how what Google says about subdomains doesn't match up with realities
- Check out some additional great comments in this thread, including a number from site owners who moved away from subdomains and saw ranking benefits, or who moved to them and saw ranking losses: https://inbound.org/discuss/it-s-2014-what-s-the-latest-thinking-on-sub-domains-vs-sub-directories
- There's another good thread (with some more examples) here: https://inbound.org/blog/the-sub-domain-vs-sub-directory-seo-debate-explained-in-one-flow-chart
Ultimately, it's up to you. I understand that Google's representatives have the authority of working at Google going for them, but I also believe they're wrong. It could be that there's no specific element that penalized subdomains and maybe they're viewed the same in Google's thinking, but there are real ways in which subdomains inherit authority that stay unique to those subdomains and it IS NOT passed between multiple subdomains evenly or equally. I have no horse in this race other than to want to help you and other site owners from struggling against rankings losses - and we've just seen too many when moving to a subdomain and too many gains moving to a subfolder not to be wary.

Hi,
I've not seen any comment from Googlers regarding this debate. I realize I'm keeping this in the Moz-sphere, which isn't quite what you're looking for, but this quote is from Moz's domain setup guide:
"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)."
I think that quote is pretty compelling towards the subdirectory side of this quandry. I also recommend checking out the comments on the Whiteboard Friday link you posted, there is plenty of evidence there as well.
Unfortunately, this debate will probably go on forever until we get definitive word from Google.

Can you share some details why you want to "move" the store locator to a subdomain? That makes me think it is already operational in a subfolder at the moment. In general, I would recommend not moving content unless there is a very good reason for it.

Faceted Navigation URLs Best Practices
Hi, We are developing new Products Pages with faceted filters. You can see it here: https://www.viatrading.com/wholesale-products/ We have a feature allowing to Order By and Group By, which alters the order of all products. There will also be the option to view Products as a table, which will contain same products but with different design and maybe slightly different content of each product. All this will happen without changing the URL, https://www.viatrading.com/all/ Is this the best practice? Thanks,

What are the best practices for geo-targeting by sub-folders?
My domain is currently targeting the US, but I'm building out sub-folders that will need to geo-target France, England, and Spain. Each country will have it's own sub-folder, and professionally translated (domain.com/france). Other than the hreflang tags, what are other best practices I can implement? Can Google Webmaster tools geo-target by subfolder? Any suggestions would be appreciated. Thanks Justin

301 Redirect of subdomain?
Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community. I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them? I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself. If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense. Any thoughts are appreciated. Thanks for your time.

How do I list the subdomains of a domain?
Hi Mozers, I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information? The only way I could think of doing it is to run a google search on; site:example.com -site:www.example.com The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www). Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information? Cheers, Dan

Removing Content 301 vs 410 question
Hello, I was hoping to get the SEOmoz community’s advice on how to remove content most effectively from a large website. I just read a very thought-provoking thread in which Dr. Pete and Kerry22 answered a question about how to cut content in order to recover from Panda. (http://www.seomoz.org/q/panda-recovery-what-is-the-best-way-to-shrink-your-index-and-make-google-aware). Kerry22 mentioned a process in which 410s would be totally visible to googlebot so that it would easily recognize the removal of content. The conversation implied that it is not just important to remove the content, but also to give google the ability to recrawl that content to indeed confirm the content was removed (as opposed to just recrawling the site and not finding the content anywhere). This really made lots of sense to me and also struck a personal chord… Our website was hit by a later Panda refresh back in March 2012, and ever since then we have been aggressive about cutting content and doing what we can to improve user experience. When we cut pages, though, we used a different approach, doing all of the below steps:
Intermediate & Advanced SEO | | Eric_R
1. We cut the pages
2. We set up permanent 301 redirects for all of them immediately.
3. And at the same time, we would always remove from our site all links pointing to these pages (to make sure users didn’t stumble upon the removed pages. When we cut the content pages, we would either delete them or unpublish them, causing them to 404 or 401, but this is probably a moot point since we gave them 301 redirects every time anyway. We thought we could signal to Google that we removed the content while avoiding generating lots of errors that way… I see that this is basically the exact opposite of Dr. Pete's advice and opposite what Kerry22 used in order to get a recovery, and meanwhile here we are still trying to help our site recover. We've been feeling that our site should no longer be under the shadow of Panda. So here is what I'm wondering, and I'd be very appreciative of advice or answers for the following questions: 1. Is it possible that Google still thinks we have this content on our site, and we continue to suffer from Panda because of this?
Could there be a residual taint caused by the way we removed it, or is it all water under the bridge at this point because Google would have figured out we removed it (albeit not in a preferred way)? 2. If there’s a possibility our former cutting process has caused lasting issues and affected how Google sees us, what can we do now (if anything) to correct the damage we did? Thank you in advance for your help,

Subdomains and SEO - Should we redirect to subfolder?
A new client has mainsite.com and a large numer of city specific sub domains i.e. albany.mainsite.com. I think that these subdomains would actually work better as subfolders i.e mainsite.com/albany rather than albany.mainsite.com. The majority of links on the subdomains link to the main site anyway i.e. mainsite.com/contactus rather than albany.mainsite.com/contactus. Having mostly main domain links on a subdomain doesnt seem like clever link architecture to me and maybe even spammy. Im not overly familiar with redirecting subdomains to subfolders. If we go the route of 301'ing subdomains to subfolders any advice/warnings?

External 404 vs Internal 404
Which one is bad? External - when someone adds an incorrect link to your site, maybe does a typo when linking to an inner page. This page never existed on your site, google shows this as a 404 in Webmaster tools. Internal - a page existed, google indexed it, and you deleted it and didnt add a 301. Internal ones are in the webmaster's control, and i can understand if google gets upset if it sees a 404 for a URL that existed before, however surely "externally created" 404 shoudnt cause any harm cause that page never existed. And someone has inserted an incorrect link to your site.
