Do you prefer subdomains or subdirectories?

A subdomain is a URL that allows you to essentially create several websites on a single domain. It’s the blog.yourcompany.com kind of URL.

Subdirectories, on the other hand, are URLs that host subsets of content in separate “folders.” It’s the yourcompany.com/blog kind of URL.

What are your preferred approach to organize website content and rank higher in search results?

From a user standpoint, I expect a subdirectory (example.com/blog) to follow the same UI as the main site (example.com). A subdomain in my mind will be a separate entity with its own UI.

This is exactly how I have things set up:

  • Hugo personal site shelbyspees.com
  • GitBook notes site notes.shelbyspees.com
  • Notist speaker portfolio speaking.shelbyspees.com

I deploy my Hugo site with Netlify, and I can also manage my subdomains there for these third-party services. Within my personal site I have subdirectory paths like /posts and /about, all built with Hugo and using the same styling.

I couldn't agree more. I feel subdomains can be useful if you are going for a subproject per se, but if you are working on the same project, website, ect. I'd definitely recommend the use of subdirectories.

From a server management perspective, subdomains. It allows much easier separation of code and resources.

From an SEO point, subfolder. Any good points on the main site will help boost the ranking of the blog.

I'm coming at these points from working in a business where the ecommerce is one platform, and the blog is a totally different one on the same tech stack.

subdirectory (path), because:

  • Maintain HTTP2/HTTP3 connection across the wild internet when going from one to the other (even if they all just go to a load balancing router)
  • Less DNS lookups
  • Shared cookies/permissions/localStorage (global darkmode, global signin)
  • Can share cached items, like brand static CSS/imagery/icons, including service worker
  • SEO, different aspects boost each other's relevance

subdomains should only be used when you explicitly need to break one of these, such as:

  • security, having a more locked-down (headers, deployment access, auditing) authentication/payment service
  • directing images/downloads to a third party cdn or service like cloudinary/imgix. (infrastructure simplification is tremendous)
  • ...I can't think of another one at the moment, things like "users of feature x and feature y don't overlap" and "I have a gorillion developers in independent teams working on independent features" has many solutions, from application routers to microfrontends.
  • short urls like youtu.be/<id> and t.me/<id> are fun yay (and they usually can be statelessly redirected at edge, let alone have content themselves, so they don't participate in a lot of the drawbacks)

Now I use subfolders, before it was subdomains, and I can say that after moving to subfolders my real estate pages starts be better indexing. The effect was not only for that page but for others as well. Hope that helps

My main website uses subdirectory naming. For example, the blog is at yoursunny.com/t/ .
The reason was that, shared hosting accounts I used initially did not support subdomains.

I tend to use short directory names:

  • /t/: "tech blog", now it's more than tech contents
  • /p/: projects
  • /m/: "me", now it's contact information and social media posts

The structure was designed in 2006, although there has been changes during the 2017 rebuild. Most of the links in past 15 years are still working, thanks to redirects.

Scripts on this website are written in PHP so they can go into subdirectories easily.


When it comes to pages published from GitHub Actions, Node.js or Go servers, etc, it would be difficult to use subdirectories. My new domain ndn.today arranges contents in subdomains. I'm getting many emails about TLS certificate issuance.

Creating new directories with same content is like wasting storage and putting extra load on wallet however addons and subdomains are good. Just need to add one more table in the database for url prefix

It's likely that the primal post misuses the term folder as the question clearly refers to the preferred way of serving content, not the actual server storage model.
Aka: whether you put stuff on subdomain or serve via subpaths from the same fqdn.
Whether you actually have folders or it's just internal routing (as you would have in react or symfony) doesn't seem relevant.

For me it depends on if it's a microfrontend architecture. Or if I'm hosting separate projects with one branded url :). My main site could be me.com, where my music might be music.me.com. In short, I use a subdomain when I am routing to a separate "server"

good question... I think it depends on your preference.
If it's something out of context for the main domain, let's say missionToMars - I would choose to be a subdomain missionToMars.dev.to.
Does that make sense ? 😬

If it’s the same subject/idea/project/technology stack, only use subdirectories.

If it’s some new idea/project but the same technology stack, subdomains are best.

If it’s a new technology stack totally different than the original, then move to a new domain.

I use a combination of the two. My main website has several subdirectories for things like my publications, research, teaching, etc, some of those with their own subdirectories. But then I use subdomains for websites for software projects such as hosting API documentation, such as chips-n-salsa.cicirello.org/ and jpt.cicirello.org/ . For the part of your question concerning ranking, I'm not sure. I didn't organize it that way for SEO purposes. I did it more for convenience. I suspect that it might not matter as much to SEO as some believe. I base this on Google's search console, which seems to treat everything within the domain as a single entity.
