The Uses of Sub-domains and Their Impact on SEO

If you do not see the need to create a sub-domain, maybe you do not understand its uses, and you fail to understand how it can help you or your website. Sub-domains have numerous applications. Ease use has the potential to affect SEO positively or negatively. Here is a look at some of the most common uses of sub-domains and their impact on SEO.

  • Sharing the root domain – You may want to share your root domain with an associate or a friend. Setting up sub-domains gives each user control over his/her website. When your associate does something stupid with their SEO, it will not affect your site.
  • Creating a website blog – Most sites host their blogs on sub-domains. This allows users to access the blog without having to go through the main site.
  • Separating departments and franchises – For businesses with many departments or branches in different locations, sub-domains allow the creation of websites for each under the same domain. This allows you to optimize content for each department or region.
  • Catering for different languages – If you are setting up a site to cater to different languages, you can set up sub-domains for each language.
