When should I use subdomains?

When should I use subdomains instead of keeping everything on the main domain?

[Jimmy_Carter]

I’ve used subdomains mostly when I need to keep things organized and separate from my main site. For example, when I launched a store for my blog, I used store.example.com. It helped me keep the blog and the shop totally independent in terms of content and functionality. I also ran it on a different CMS than my main site, which was only possible because I used a subdomain. So if you’re looking to separate different sections of your site — like a forum, support portal, or store — subdomains are super helpful.

+1 to that. Subdomains are my go-to when we have different teams managing different areas. For example, marketing runs blog.example.com and the devs run the main site. Keeps things clean. Also handy for testing: beta.example.com is our staging site.

We use subdomains in our company mainly for testing environments — like beta.example.com or dev.example.com. It’s safer than making changes on the live site. Subdomains also work great if you’re targeting different countries, like au.example.com for Australia or uk.example.com for the UK. Just be sure to use the correct hreflang tags and local content to make it effective.

Usually go for subdomains when you want to keep things organized, like having a separate blog or store. They're also handy for testing (beta.example.com) or targeting different countries (like uk.example.com).
