When managing your website’s SEO, one of the questions that often arises is whether to use a subdomain or stick to a subdirectory.
Subdomains are an intriguing option for segmenting content, but they can also have a significant impact on your SEO strategy.
So, should you use a subdomain for your next SEO project?
What is a sub domain?
A subdomain is like a “mini-site” that branches off your main domain, creating a distinct section while staying connected to your brand.
For example, in the URL seo.klubclicks.com, the word “SEO” is the subdomain.
Subdomains are great for hosting content that’s different or separate from your main site, such as an online store, blog, or regional website. They allow you to organise your website in a way that feels tailored to specific purposes or audiences.
This setup differs from a subdirectory, which organises content within folders on your main domain—for instance, example.com/store.
While both subdomains and subdirectories help structure your site, they each have unique pros and cons, particularly when it comes to SEO. Choosing the right one depends on your goals and strategy.
Would you like me to expand on how these options impact SEO or give real-world examples?
Subdomain vs. Subdirectory: What’s the Difference for SEO?
When deciding between Subdomains vs SubDirectories can cause headaches.
The main difference lies in how search engines perceive subdomains versus subdirectories.
- Subdomains: Treated as separate entities. They’re indexed and ranked independently from your main site.
- Subdirectories: Treated as part of the primary domain. Links and authority from the subdirectory directly benefit the root domain.
For instance, if your blog lives at blog.example.com (a subdomain), the links it earns might not enhance the SEO of example.com.
On the other hand, if it’s at klubclicks.com/blog (a subdirectory), those links contribute to the main site’s authority.
When to Use a Subdomain
Using a subdomain isn’t inherently bad for SEO, but it can make things much more time consuming.
For example, you can use a sub domain to;
Targeting Different Audiences
If your business operates in different countries or languages, a subdomain like de.klubclicks.com can help tailor content to a specific region (in this case German users) while keeping it separate from the main site.
Segmenting Content
Subdomains work well for projects that are totally separate from your core business.
For example, if you have an ecommerce site that hosts an educational platform, choosing a subdomain like learn.klubclicks.com can help differentiate the two.
Testing or Staging
Developers often use subdomains to test features or new designs without affecting the live site.
This is perhaps one of the most common use of a subdomain.
Supporting a Niche
If you’re creating highly specialised content that doesn’t align with your main site, a subdomain can help maintain focus while building authority in that niche.
Google loves websites that focus on one niche, when you start talking about other niches, this will dilute your website authority and make it harder to rank for all topics.
How Subdomains Can Harm Your SEO
While subdomains can have their advantages, they can also come with specific challenges:
- Splitting Link Equity: Subdomains don’t automatically share link authority with your main domain. This can make it harder to build overall domain strength.
- Complex SEO Management: Optimising multiple subdomains can feel like managing multiple websites, requiring separate keyword strategies and link-building efforts.
- Indexing Issues: Search engines might take longer to index a subdomain, especially if it’s new or not well-integrated with the main site.
Why You Should Think Twice About a Subdomain Blog
One of the most debated topics in SEO is whether to host your blog on a subdomain or a subdirectory.
If your blog content directly supports your main site (e.g., an ecommerce site publishing guides or product reviews), placing it in a subdirectory (like example.com/blog) is usually better.
This way, the backlinks and traffic generated by the blog strengthen the SEO of the main domain.
However, if the blog is on a completely different topic—say, a restaurant creating a blog about pop culture—it might make sense to host it on a subdomain like blog.example.com to keep the audiences distinct.
Subdomains: The Verdict
Ultimately, the choice between a subdomain and a subdirectory boils down to your business goals and SEO strategy.
Choose a subdomain if:
- You need to differentiate a specific section of your site.
- The content’s audience or focus is entirely separate from your main site.
Choose a subdirectory if:
- You want all your content to strengthen your primary domain’s SEO.
- The content supports your core business and keywords.
No matter what you choose, ensure it aligns with your long-term strategy.
The right choice can enhance your brand visibility, while the wrong one may lead to missed SEO opportunities.
