Subdomain vs Subdirectory: What They Are?

A subdomain is a segment of a domain name placed before the top-level domain (TLD). Its purpose is to structure a website’s content into distinct sections or establish related sub-websites associated with the main site. For instance, a business might employ a subdomain for its blog, another subdomain for a support forum, and yet another subdomain for its online store.

When expressed in a URL, subdomains precede the main domain name. In the URL, “blog” denotes the subdomain, while “” represents the main domain name.

What is a Subdirectory?

In the context of SEO, a subdirectory, also referred to as a subfolder, is a directory situated within the primary domain of a website. Its purpose is to provide a method for organizing and categorizing content on the website, enhancing the ease of navigation and comprehension of the site’s structure for both users and search engines.

Subdirectories are commonly employed to cluster related content, such as blog posts, articles, product pages, or categories.

Subdomain vs Subdirectory: How they Affect SEO?

Subdomains may not leverage the full benefit of accumulated backlinks earned by the main domain over time because Google treats them as distinct entities, crawling and indexing them independently. This means that acquiring backlinks for each subdomain becomes a separate task, demanding considerable time and effort. Without dedicated efforts, content on subdomains may not achieve optimal rankings compared to hosting it in subdirectories. Additionally, managing numerous subdomains can pose challenges, leading to issues such as duplicate content and inadequate interlinking between the main domain and its subdomains, potentially complicating overall website maintenance.


Google typically treats subdirectories as integral parts of the main domain, ensuring that the hard work invested in building backlinks is more likely to benefit all content under the main domain, including those in subdirectories. This is due to the equitable distribution of link value throughout the domain. The advantage of using subdirectories extends to simplified management, as everything is neatly organized under one domain umbrella, reducing technical complexities. Unlike subdomains, there’s no need to set up and maintain separate hosting, and the creation of new subdirectories for various website sections, like a blog or news section, is more straightforward. Additionally, tracking website data becomes more seamless with subdirectories, providing a comprehensive view of site performance in one centralized location.

Subdomain vs Subdirectory: Which is Best for SEO?

Which is Best for SEO

When faced with the selection of whether to choose a subdomain or a subdirectory for your site, it is vital to assess the precise necessities and desires of your website. Each one comes with its own set of advantages and downsides, and the most beneficial desire hinges on your unique situation.

Subdomains provide a clear delineation between different website sections, allowing for distinct branding and identity. They can be treated as independent entities by search engines, making them suitable for sites with diverse target audiences or content objectives. However, subdomains may potentially dilute link equity and can entail more intricate management compared to subdirectories.

On the flip side, subdirectories consolidate link equity, rendering them more SEO-friendly overall. They are easier to manage and maintain as they fall under the main domain structure. Yet, subdirectories might not offer the same level of branding flexibility as subdomains and may require additional effort for search engine optimization.

Finally, the choice between a subdomain and a subdirectory should be guided by a careful consideration of your website’s specific needs and objectives. If there’s a need for a clear separation of content and distinct branding, a subdomain might be a suitable choice. Conversely, if SEO optimization and a well-organized site structure are top priorities, subdirectories may prove to be a more fitting option.


In conclusion, both subdomains and subdirectories serve specific purposes in organizing website content and URLs. Subdomains are an excellent choice when you want to create separate sections for different functions or target different audiences within your website. They provide a sense of independence and can be beneficial for branding purposes. On the other hand, subdirectories work well when you want to maintain a cohesive structure and have all your content under one domain. They are relatively simpler to set up and manage.

When deciding between subdomains and subdirectories, it’s essential to consider factors such as your website’s goals, content organization, SEO strategy, user experience, and technical feasibility. While there is no one-size-fits-all answer, understanding the pros and cons of each option will help you make an informed decision that aligns with your specific needs.
