There are two common sorts of site structures for websites, and the debate over which is preferable has raged for years.
We’re discussing subdomains vs. subfolders. What effect do they have on your SEO? How do they make your website more search engine friendly? Which is the superior option? Let’s take a closer look at the subdomain vs. subfolder dispute and see which one wins out.

Difference Between a Subdomain & Subfolder

While there are many parallels between subdomains and subfolders, they are also very different.

A subfolder is a “child directory” that works under the supervision of a parent directory. Simply described, it is a folder within a home directory that is beneath another one. They work in the same way as a path within a parent domain.

Subdomains are similar to subdomains in that they are likewise a content repository, but the primary distinction is that subdomains have their own URLs, allowing them to be accessed directly, just like a normal website.

When websites don’t want some aspects of their root domains to be visible, they create subdomains. These domains each have a distinct purpose, and Google treats them as distinct webpages. Netflix, for example, has a long list of subdomains, each of which serves a particular purpose, such as:


Now that you know what the difference between a domain and a subdomain is, let’s look at how subdomains work and why they’re useful.

How do subdomains look on a server?

As previously stated, Netflix has a number of subdomains, each of which functions as a separate organisation with its own set of servers. The expense of running separate servers and the memory space required for subdomains were too expensive in the early 2000s. However, with mobile-first indexing, the subdomain landscape has shifted. Subdomains are primarily utilised to host mobile versions of your websites these days. If your website’s primary domain is, the subdomain will be something like “”

Assume you want a subdomain where clients can fill out contact forms. would be your contact subdomain.

Subdomains are used by businesses all over the world to host multilingual versions of their websites or to store large amounts of data such as large downloadable contents or blogs.

Why Use Subdomains?

Technical Reasons

A password-protected subdomain is frequently used by web developers to host staging versions of websites for testing new templates, experimenting with designs, and more.

Developers can easily establish a subdomain that mirrors the main website. This is accomplished by creating a new database and reinstalling the main website. Furthermore, search engine crawlers are unable to locate this subdomain because it is not linked anywhere on the internet. Even if they did, the crawlers would be unable to access these subdomains because they are password-protected.

However, using subdirectories to do the same might be tough, as there is a significant risk of serious problems in the link structure, which can be difficult to manoeuvre around.

Subdomains are more popular among developers since they allow them to experiment with different layout templates, designs, plugins, and other technologies without affecting the main website.

Branding Reasons

On a website, it is always better for a brand to divide its distinct areas. Using Netflix as an example, they offer a dedicated support domain where users can quickly access resources such as FAQs, manuals, and other help materials.

SEO Reasons

There are a variety of reasons why hosting a subdomain could be beneficial to your website’s SEO. For example, if you want to publish a topic that has nothing to do with your main site, a subdomain is a great place to start. This will separate this new topic into its own URL, separate from your main website but still tied to it.

News and media publishing websites that contain a subdomain for recipe content are a good illustration of this. It allows them to isolate wholly unrelated content from their specialisation while keeping it static and consistent with the brand.

Because Google treats subdomains as separate websites, putting SEO-optimized content on them can raise their ranks and expand your brand’s reach. The subdomain can rank independently and bring in new demographics to your website, resulting in significant organic traffic growth.

Improves Rankings

Subdomains integrate their own SEO rankings with the parent website effortlessly. This is especially useful for companies who want to segment their content into different specializations and domains.

Because Google considers subdomains to be separate websites, they are ranked separately. Internal linking on these subdomains, on the other hand, can help Google connect the dots and expand the reach of your parent website. Furthermore, organic traffic from users who visit these subdomains and engage with the content can be directed to your main website. This will aid in the improvement of your website’s rankings.

User Segmentation

Because most subdomains are utilised for specific reasons, they aid in the separation of users’ diverse use cases. Netflix accomplishes this by redirecting visitors to subdomains dedicated to specific functions, as previously described.

Enhances user experience

Businesses can better serve their customers by having various subdomains. For example, if someone is seeking for payment assistance, Netflix’s support subdomain contains all of the information they require rather than requiring them to navigate through multiple pages to find the information they require.

Link Equity

For search engines, link equity is a significant ranking element. Links on a website should traditionally convey authority and value from one page to the next. When search engines talk about thematic relevance, content quality, and relevancy of the content referenced, they’re referring to this. Search engines do this by thoroughly crawling a website’s subfolders.

Increases domain authority

If your website has links from authoritative domains, it tells search engines that your content is of high quality and comes from trustworthy sources. This aids in the growth of your website’s domain authority. Improved domain authority helps you get ahead of your competition on SERP rankings because it is a trailing measure rather than a ranking element.

Google on Subdomains vs Subfolders

Google’s algorithms handle both subdomains and subfolders in the same way, according to ohn Mueller, a Senior Analyst and Google’s Head of Search Trends at Google. He stated

This does not appear to be totally accurate, as there have been many questions regarding whether Google’s algorithms treat subdomains and subfolders in the same way. So, which one do you think you should go with for your website? Let’s wait and see what the outcome is.

Subdomain or Subfolder? What to Choose

While John Mueller claims that Google has improved its ability to distinguish subdomains from main websites and assign keywords to root URLs, a number of firms have found the opposite to be true.

Many research were undertaken to look at analytic proof, and the data revealed that the outcomes do not match what Google claims. The keywords employed by subdomains were also assigned to the parent domain in these investigations.

As a result, it was determined that employing subdomains since a website structure can be risky, as it may cause search engines to misidentify your subdomain and parent domain.


This can have unintended consequences, such as lowering your website’s backlink strength, dividing terms among subdomains, and so on. For example, one study discovered that the backlink strength of websites began to flow to their subdomains on a regular basis. As a result, the keyword density on the primary websites has been diluted.

Subfolders certainly emerge as a winner for SEO purposes based on these data. Subdomains, on the other hand, are useful for websites that have conceptually distinct content and want to keep it separate from their main domain.

Search engines are more capable of providing metrics from subfolders. Subfolders are recommended if you employ analytics software on your website, such as HubSpot. Subdomains, on the other hand, are a wonderful way to store CTA pages or landing pages for tracking data with tools like Google Analytics. The structure of your website will always be a question of personal preference. The primary message here is that subfolders should be considered before a subdomain. If their implementation is justified in your use case, the latter should be preferred.
