When it comes to SEO, most of the questions were unanswered and ends with Confusion. SubDomain or SubDirectory is one of the ongoing debate among the SEO people.
According to Google, Subdomain or Subdirectory anything is fine. But making changes in URL Structure will take time to get settle down in Search Results. So John Mueller from Google recommends to choose the one which is comfortable for you. Check the below video by John Mueller which is about “SubDomain or SubFolder”.
According to this Video, it is very clear that Google treats subdomain and subdirectory as a same thing. So it is better to choose the best thing for you.
SEO Experts Disagree This!
Even though Google treats the SubDomain and SubDirectory as a same one, the effort involved will vary. Sub Domain or Sub Directory, anyway it is going to get ranked. But the effort needed to rank a sub domain is much higher when comparing to sub directory.
Normally Google treats the Sub Domain as its own entity. Most of the sites used to place the different content in the Sub Domains.
Why Choose Sub Domain over Sub Folder?
If you are creating subdomains and choosing to provide different things, then it will worth it. For example: You have a domain called clickdo.in and you are creating subdomains like videos.clickdo.in, music.clickdo.in, marketing.clickdo.in. Here you can see videos, music and marketing – everything is going to provide something different from other. Normally it acts as a separate business and which looks like individual site.
Normally, if you are getting some links to your site then mostly it will point to one of your domains. Because each subdomain is different from other. In this case, it will be easy to project it as a individual to rank in top of Search Results.
Why Choose Sub Folder over Sub Domain?
Most of the Business won’t be targeting on multiple business ideas. Also I have seen most of the sites having subdomains for their regular blog to increase their site authority. But does it happens? is a hypothetical question. So it is better to choose the sub folder for topic based contents which helps them to rank easily and the site will look user friendly for the visitors.
