Many SEO experts debate whether subdomains or subdirectories are better for SEO. Let's understand the differences between these two approaches and consider their impact on SEO.
A subdomain is a separate part of a website that allows for different types of content and structures than the main domain. While subdirectories are part of the same hierarchy as the main domain, a subdomain is treated as a separate entity.
Subdomains are usually located before the main domain in the URL, such as blog.example.com, as opposed to subdirectories, which look like example.com/blog.
A subdomain can be useful if part of your site has enough content that it requires its own structure. A subdirectory stores all elements within the main domain.
When should you use a subdomain? Here are some common cases:
1. **Support**: If you need to highlight a separate category such as customer support, you can use a subdomain. For example, you could dedicate support.example.com to customer support, as opposed to using a subdirectory on the main site.
2. **Locations**: If your site serves multiple regions or countries, using subdomains will help you manage content for each territory more efficiently. For example, you can create subdomains for different languages and countries, such as de.example.com or uk.example.com.
3. **Blog**: If your blog is a fairly large and separate content project, it can be placed on a subdomain to differentiate it from the main site and improve the structure.
4. **Online Store**: If your site sells products, hosting your store on a subdomain like shop.example.com can be a good solution for organizing your content.
5. **Events**: For large events or conferences, separate subdomains are often created to highlight this content. For example, events.example.com can be used to host events.
Ultimately, subdomains remain part of the main site, but when indexed by a search engine, they can be treated as separate entities. Let's look at how subdomains and subdirectories affect SEO.
SEO experts are divided on the extent to which subdomains can affect a site's ranking. Some experts believe that Google may treat a subdomain as a separate site from the main domain. However, Google claims that its algorithms recognize subdomains as extensions of the main domain.
According to Google, the search engine indexes and ranks subdomains and subdirectories equally.
Renowned Google analyst, John Mueller, in one of his interviews argued that subdomains do not have a negative impact on SEO since Google's algorithms can differentiate between the main domain and the subdomain as part of the same website.
Some experts believe that subdomains may not transfer link mass from the main site. This means that the subdomain may not inherit the link weight that the main site received. In this case, if the main site and subdomain use the same keywords, they can compete with each other.
On the other hand, there is an argument that subdomains can help improve navigation and user experience on a website, leading to improved SEO. Subdomains can also be useful for large organizations where different subdomains serve different functions, such as support, a blog, or an online store.
For example, in large companies you might see subdomains such as cars.example.com, shop.example.com, and movies.example.com, where each subdomain serves a different purpose.
Subdomains can also help create niche authorities. For example, if your blog is related to a specific topic, you can host it on a subdomain so that it feels like a separate entity from the main site.
If your site does not have a complex hierarchical structure, using subdirectories may make more sense. In this case, all links on your site will strengthen the main domain, which will help transfer link juice.
Ultimately, the choice between subdomains and subdirectories depends on the structure and needs of your site. Subdomains can be useful for organizing and separating content on more complex sites, but if your goal is to maximize the transfer of link juice to the main domain, subdirectories are a better choice.
