SEO Comparison: Subdomains versus Subdirectories
In the world of website development, one of the key decisions that businesses face is whether to use subdomains or subdirectories. Both options have their unique benefits and drawbacks, and the choice can significantly impact the entire business.
Subdomains, an extension of the main domain, are added as a prefix to the website URL and become a separate property within the domain. For instance, is a subdomain. They are commonly used by brands offering a suite of products, services, content, etc., to build authority and boost organic traffic for each property. They also offer flexibility, making them ideal when wanting to launch different offerings in the future and need more flexibility to scale each product/service.
Subdomains are particularly useful when separate analytics for each site are desired, when working with many departments or external agencies, each with their own workflows, and when different parts of the website run on different technology stacks. They also provide a clean separation, which can be beneficial in sandboxing work without affecting the main site's performance or CMS structure when working with external vendors.
However, subdomains come with trade-offs. They take longer to gain SEO authority, require additional SSL certificates, and DNS management, and are more complex to implement and maintain than subdirectories. They also may lead to major differences in how a site performs in search, with subdirectories having the advantage when it comes to search visibility and subdomains requiring more effort to build link equity and authority.
On the other hand, subdirectories are subfolders within the main website that categorize different pages on the site into folders within the main domain. For example, . They are popular for SEO-focused sites because they consolidate authority under one domain, but they can create overly complex URL structures when deeply nested and have limited flexibility for different design/branding needs across sections.
Subdirectories work best for unified data and easier tracking of user journeys across the site. They are a better setup for a single team managing all the content, as they allow for centralized content management and maintaining uniformity. They are also popular for international websites to deliver customized user experiences and follow a targeted SEO strategy for each market.
The decision between using a subdomain or a subdirectory for a new arm of a website can impact SEO performance and user interaction. It's essential to consider factors such as business objectives, technical setup, and international SEO considerations before making a choice.
In conclusion, both subdomains and subdirectories have their strengths and weaknesses, and the best choice depends on the specific needs and goals of the business. It's recommended to consult with an experienced SEO consultant like Edward Bate to make an informed decision.
