When it comes to organising a website’s content, the debate over using a subdomain or a subdirectory is a long-standing one, especially when considering the impact on SEO.
Both approaches have their benefits and drawbacks, but the right choice can significantly influence your site’s visibility on search engines. In this article, we will break down the differences between blog subdomains and subdirectories, and provide insight into which option may be more beneficial for your SEO strategy.
What is a Subdomain?
A subdomain is a separate section of your website that exists independently of your main domain. In this structure, the “blog” acts as its entity, somewhat detached from the main site. Search engines often treat subdomains as standalone sites, which means that the content on a subdomain may not always contribute to the SEO authority of the primary domain.
Many businesses use subdomains when they want to separate content that serves a different purpose or audience. For example, an e-commerce store might use a subdomain for its blog or support site to keep the customer experience distinct. However, this separation can create challenges when it comes to search engine optimisation, as subdomains don’t always inherit the SEO benefits from the main site.
What is a Subdirectory?
A subdirectory, also known as a subfolder, is an extension of your main domain. It follows the structure example.com/blog, where the blog is housed within the main site rather than as a separate entity.
In this arrangement, the blog or content within the subdirectory is more tightly connected to the main domain in terms of SEO authority.
Subdirectories are often favoured by businesses that want their content to directly contribute to their primary domain’s search rankings. Since search engines treat subdirectories as part of the main website, any backlinks, traffic, or SEO signals generated from the subdirectory are passed on to the primary domain. This can be beneficial for improving the overall authority and ranking of your website.
For many companies, subdirectories offer a straightforward way to organise content, especially when the blog or other sections serve the same target audience and purpose as the rest of the site.
SEO Impact of Subdomains vs Subdirectories
When it comes to SEO, the choice between a subdomain and a subdirectory can have a notable impact on how search engines view and rank your website. Understanding the key differences will help you make an informed decision for your site’s SEO strategy.
Subdomains and SEO
Subdomains are often treated as separate entities by search engines like Google. This means that any SEO authority or link equity built on the subdomain may not directly transfer to the main domain. While this separation can be useful for segmenting content that targets different audiences, it can also dilute your SEO efforts if your goal is to strengthen your primary domain’s rankings.
However, there are cases where using a subdomain may be advantageous. If the content on the subdomain is vastly different from the core content of your main site, such as a support section or a forum, it may make sense to keep it separate. This can allow the subdomain to perform well in its niche, although it may not contribute to the SEO power of your main website.
Subdirectories and SEO
Subdirectories, on the other hand, are typically more SEO-friendly when your goal is to boost your main domain’s authority. Since the content within a subdirectory is seen as part of the main site, any traffic, backlinks, and other SEO signals it generates are passed on to the main domain. This creates a unified SEO structure that can improve the visibility and rankings of your entire site.
For blogs or other content-heavy sections, subdirectories tend to be the preferred choice. They allow you to create new content without splitting your SEO efforts, making it easier to rank for related keywords and phrases that benefit your primary domain. Additionally, search engines generally find it easier to crawl and index subdirectories as part of the existing site, which can contribute to faster improvements in rankings.
Which Should You Choose for Your Blog?
Deciding between a subdomain and a subdirectory ultimately depends on your goals and how your blog fits into your overall business strategy.
If your blog content aligns closely with your main site’s objectives and you want it to directly contribute to your primary domain’s SEO authority, a subdirectory is likely the better option. This means that all SEO signals, such as backlinks and traffic, flow back to your main domain, helping to strengthen its overall rankings.
On the other hand, if your blog covers a completely different topic or serves a separate audience, you might consider using a subdomain. This approach allows for greater flexibility in managing content, especially if your blog requires a unique design or content management system. However, keep in mind that the SEO benefits of a subdomain won’t always contribute to your main site, which could dilute your SEO efforts if not carefully managed.
In most cases, businesses aiming to boost the SEO performance of their main site will find that using a subdirectory offers more advantages. It simplifies content management and provides a cohesive structure that improves your site’s SEO presence.
When choosing between a subdomain and a subdirectory for your blog, the decision comes down to your specific SEO goals and how closely your blog relates to your main site’s purpose. While subdomains provide more independence, they often fail to transfer SEO authority to the main domain.
Subdirectories, on the other hand, contribute directly to the SEO strength of your primary site, making them the preferred option for most businesses looking to boost their overall search rankings.
