Subdomains are the third level domains that are used to organize your website content. They are just like folders under your root directory. But they will have a special URL to access.
http://www.yoursite.com is the regular URL without a subdomain.
http://products.yoursite.com is a URL with subdomain “products”.
Here the: .com is the first level domain
your site is the second level domain
products are the third level domain
What is the purpose of subdomains?
- You can organize your web site like support, help and FAQ at ‘http://support.yoursite.com’.And your products and order link under ‘http://store.yoursite.com’ etc.
- If you have members, or you want to share your disk space with your friends and family, you can create a subdomain for each of them and give access with their user name and password.
- You can also organize the email addresses that comes to separate departments on your web site like [email protected], [email protected], etc.
- Long URLs are cut short to a subdomain, so it is easy to remember the short URL instead of long URLs. Especially this is true with your affiliate links which are long and with many special characters like ‘?’,’&’ etc. This is hard to remember. So in these cases creating a subdomain for that long URL helps to remember it well.
