Deciding Between Blog Subdomains and Subdirectories for SEO: A Comprehensive Guide

The structure of your website is crucial for success, especially if you’re using inbound marketing. One important decision is where to host your blog: on a subdomain or as a subdirectory of your main site.


The debate over which is better for SEO has been ongoing, with Google suggesting you choose what fits your long-term strategy. However, many SEO experts recommend hosting your blog as a subdirectory, as it offers better SEO benefits.


This guide explores the subdomain vs. subdirectory debate, providing insights to help you make an informed decision. Whether you’re looking for SEO tips or considering a switch from a subdomain to a subdirectory, this article can guide you through the process. Discover the details of the blog subdomain dilemma and understand how your choice can impact your website’s visibility and engagement with your audience.

What Is a Blog Subdomain?

A subdomain, such as blog.example.com, functions as an extension to your primary domain (example.com). Typically, organizations utilize subdomains for testing new website elements, designs, or tools, and also for hosting online stores.

The Role of Subdomains in SEO

When considering subdomains and SEO, it is crucial to understand why subdomains are often an inappropriate choice. Explore the reasons in the following sections.

Benefits of Subdomains for SEO

  • Effective Brand Management: Corporations with multiple brands under one domain can efficiently organize their holdings using subdomains for SEO. However, for businesses with a single brand, the use of subdomains for hosting a blog may not be advantageous.
  • Support for International SEO Strategy: Subdomains can helpi international SEO by functioning as separate sites, particularly when targeting new markets. Despite this, it’s important to note that hosting the main blog on a subdomain may not align with SEO best practices.

Drawbacks of Subdomains for SEO

  • Isolation from the Main Website: Google treats subdomains as independent entities from the main website. This results in the need to attract backlinks to both the main site and the subdomain when the blog is hosted on the latter.
  • Increased Workload without Added Benefits: Hosting a blog on a subdomain requires additional effort in managing separate backlink strategies for the main site and the subdomain. For most businesses, especially small-to-midsized ones, this extra workload doesn’t contribute to SEO success.

Impact of Subdomains on SEO

When deciding where to host your blog, it’s clear that subdomains can have a negative impact on SEO. The additional workload and the need for independent backlink strategies make hosting a blog on a subdomain an inefficient choice. To streamline your SEO efforts, consider creating or moving your blog to your main site.

What Is a Subdirectory?

A subdirectory, exemplified by the format example.com/blog/, is essentially a subfolder located within your domain (example.com). These subfolders are employed by businesses to systematically organize site content, such as grouping product pages within a subdirectory named “products” (example.com/products/).

The Role of Subdirectories in SEO

When delving into the realm of subdirectories and SEO, it becomes clear that subdirectories often present the most logical choice. Explore the reasons behind this choice in the subsequent sections.

Benefits of Subdirectories in SEO

  • Concentrated Link-Building Efforts: Subdirectories enable businesses to channel their time, energy, and resources into a singular link-building strategy. This approach avoids the need to attract links to both the main website and subdomains, maximizing the impact of SEO on the company.
  • Enhanced Search Result Rankings: Focusing on subdirectories as opposed to subdomains accelerates the process of improving search result rankings. A unified SEO effort on a single site contributes to the development of an authoritative and trustworthy backlink profile, leading to faster and higher-ranking content.
  • Simplified Google Analytics Tracking: Hosting a blog on the main website simplifies tracking site performance in Google Analytics. By utilizing subdirectories, businesses can seamlessly monitor page views, bounce rates, and conversion rates from a single platform, saving time and streamlining performance evaluation.

Drawbacks of Subdirectories in SEO

While subdirectories offer numerous benefits, they may pose challenges for global companies with multiple brands. 

Do Subdirectories Impact SEO?

In the context of global brands opting for subdirectories over subdomains, there may be drawbacks to the SEO strategy. However, it is essential to recognize that, overall, subdirectories do not inherently harm SEO. Their organizational benefits, unified link building, and support for the broader SEO strategy make them valuable tools for website management.

Subdomains vs. Subdirectories for SEO

Which is more beneficial for SEO: subdomains or subdirectories? According to Google, both are treated equally in terms of traffic. However, altering site structures can temporarily affect search traffic until things stabilize, so consistency in your chosen approach is crucial.

There’s not a unanimous consensus on this matter. While subdomains work well for major entities like Disney, with diverse areas of interest such as movies, theme parks, and merchandise, smaller businesses with more specialized niches may not reap the same benefits.

For instance, a content marketing company focusing on blogging tips or a cryptocurrency startup discussing decentralization and smart contracts may find that using subdirectories improves overall SEO traffic to their main domain, aligning with their specific goals. Unlike Disney, which draws substantial traffic to each subdomain, businesses with narrower focuses may find subdirectories more advantageous for enhancing their SEO performance.

Should You Use a Subdomain or a Subdirectory for Your Blog?

When it comes to SEO considerations, both subdomains and subdirectories are equally effective, according to Google. However, there are distinct reasons to opt for one over the other.


If your business has a global presence and aims to provide tailored content for each region, subdomains offer a practical solution. For instance, employing subdomains like es.semrush.com and fr.semrush.com allows catering to specific regions, delivering a more relevant and personalized experience.


Subdomains are commonly used for staging environments where testing new features, updates, or designs occurs before implementation on the main site. Examples include dev.example.com or staging.example.com, enabling developers to identify and rectify issues before the changes go live.


When a specific section of your website requires a distinct design and functionality from the main site, a subdomain can provide the necessary separation. For example, using a subdomain like shop.example.com for the ecommerce section while keeping the main domain as example.com.


Choosing a subdirectory may be more beneficial in the following situations. If you prefer a straightforward website setup and maintenance process, subdirectories are a suitable choice. Unlike subdomains, subdirectories don’t necessitate additional technical configurations, such as setting up a new hosting account, SSL certificate, or analytics tracking.


Subdirectories contribute to maintaining consistent branding and user experience across the entire website. They share the same design elements as the main website, ensuring a unified and coherent impression for visitors. In contrast, subdomains can introduce confusion due to potential differences in design elements, leading visitors to question the authenticity of the subdomain.

How to Move Your Blog From Your Subdomain to Your Main Site?

Deliberating over the decision of whether to maintain your blog on a subdomain or integrate it with your primary website is a crucial consideration. Opting to redirect your blog to your main site, especially if your business doesn’t involve distinct, independently operated brands, can significantly enhance your overall SEO strategy and contribute to long-term success. Despite the potential initial decline in blog traffic, the benefits of this strategic move are substantial.

To successfully migrate your blog from its subdomain to the main site, follow these key steps:

  • Identify your company’s developer: Locate and engage the expertise of your company’s developer to facilitate a smooth transition.
  • Back up your subdomain: Ensure that your developer performs a comprehensive backup of your existing blog content on the subdomain to safeguard against any data loss during the migration process.
  • Implement a 301 redirect: Task your developer with setting up a 301 redirect for your blog and its individual posts to guide users to the new domain. This is a crucial step to maintain the integrity of your SEO efforts and ensure a seamless user experience.

Given the critical nature of these steps, it is advisable to collaborate with a proficient SEO agency if your website developer lacks expertise in SEO. 

By doing so, you can navigate the complexities of the migration process with confidence, ensuring a successful and optimized transition for your blog.

Final Thoughts

The choice between hosting a blog on a subdomain or a subdirectory significantly influences SEO strategy. While Google advocates flexibility, SEO experts generally favor subdirectories for their focused link-building, improved search rankings, and simplified analytics tracking.


Subdomains, beneficial for global brands and specific design needs, come with drawbacks like isolation and increased workload. The decision depends on business specifics, with subdomains fitting global or section-specific requirements, and subdirectories offering a straightforward setup and unified user experience. Transitioning from a subdomain to a subdirectory requires careful planning and collaboration with developers, but the long-term benefits of optimized SEO and user experience make it a strategic move worth considering.
