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://mza.seotoolninja.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.

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

URL categorization / subfolders
Hi Mozzers, We're currently in the process of a website redesign with new CMS and have the opportunity to change URL and structure. I would love some opinions as to what the best practise will be. A quick prerequisite, the website is entirely about France. French property, living, holidays, forum - everything. Therefore, we're unsure of the usage of the word France/French. Presently, we're running Classic ASP which allows for one subfolder then dynamic article ID. In my examples, I will take our activity holidays URL. At present this is /france-activity-holidays/DisplayArticle.asp?ID=12345. We know that DisplayArticle.asp?ID=12345 will simply become [article-title], however, its the preceding subfolders I would like some help with. Here are our thoughts on the options available. Can you please vote as to which you think is the best? /france-activity-holidays/ (one subfolder per category, as at present) /france/holidays/activity/ (always have a first subfolder with the word france) /holidays-to-france/activity-holidays/ (france in the primary subfolder) /holidays/activity-holidays-france/ (france in the secondary subfolder) /holidays/activity/ (because the whole website is about France, it is redundant to have /france/) /French-holidays/activity/ My gut feeling is either number 2 or 5. Concise, good for UX, OK for SEO. However, there is very little information around that is relevant to our sector. Thanks in advance! Matt

How best to structure wordpress site.
I need help on how to structure my wordpress site to avoid duplicate content issues. Basically I have a main category page for each of my targeted keywords (about 12). From each of those though I want to create a category for each county in the uk and then about 15 towns within each county. This means I'm creating a LOT of categories. Eg: /plumbers/lincolnshire/lincoln x 15 other counties and towns /local-plumbers/cambridgeshire/cambridge x 15 other counties and towns (I have about 12 main keywords I'm going after) I'm basically creating a category for every town in the UK going after long tail keywords. What is the best way to manage this in wordpress? Advice from another question I posted on here is to write a unique category description for each one as the posts in each category are almost identical. The other problem here is I'm ending up with hundreds of links on a page. (They can't all be seen by the user as I'm using a drop down menu plugin). Any advice appreciated.

Domain Name Change - Best Practices?
Good day guys, We got a restaurant that is changing its name and domain. However they are keeping the same server location, same content and same pages (we are just changing the logo on the website). It just has to go a new domain. We don't want to lose the value of the current site, and we want to avoid any duplicate penalties. Could you please advise of the best practices of doing a domain name change? Thank you.

How can I tell which website pages are hosted on the root domain vs the www subdomain?
One of the SEOmoz help desk professionals told me this today regarding some of my website pages. "it looks like you have pages hosted as separate pages on both the root domain and the www subdomain, which means that these pages are competing for rankings and authority. You may want to consider a 301 redirect or the use of rel=canonical tags.". Can anyone help me understand this? How can I tell which pages are which?

Best way to merge 2 ecommerce sites
Our Client owns two ecommerce websites. Website A sells 20 related brands. Website has improving search rank, but not normally on the second to fourth page of google. Website B was purchased from a competitor. It has 1 brand (also sold on site A). Search results are normally high on the first page of google. Client wants to consider merging the two sites. We are looking at options. Option 1: Do nothing, site B dominates it’s brand, but this will not do anything to boost site A. Option 2: keep both sites running, but put lots of canonical tags on site B pointing to site A Option 3: close down site B and make a lot of 301 redirects to site A Option 4: ??? Any thoughts on this would be great. We want to do this in a way that boosts site A as much as possible without losing sales on the one brand that site B sells.
