When using Lyris HQ, it's helpful to have an understanding of domain names and subdomain names, especially when performing set-up operations.
Let's analyze the different parts of the following:
www.lyris.com
Even though this is commonly referred to as a "domain name," it actually consists of three different domains:
com: top-level domain
lyris: second-level domain
www: third-level domain
Each domain is considered to be a subdomain of the domain to its right. The exception to this is com--as the label "top-level domain" implies, it's at the top of the domain hierarchy and therefore is not a subdomain. The second-level domain, lyris, is a subdomain of com, and www is a subdomain of lyris.
So, let's say that here at Lyris we decided to have different departments represented by different domain names. We could create the following:
sales.lyris.com
marketing.lyris.com
support.lyris.com
engineering.lyris.com
In this case, sales, marketing, support, and engineering are all considered to be subdomains of lyris.com.
Examples of where this knowledge comes in handy while setting up web analytics and landing pages. In the Web Analytics tab, there is an Add button and an Add Sub-Domain button.
If your existing domain name is www.lyris.com, and you wish to add a name for a completely different domain such as www.example.com, you would click the Add button. When you finish, it looks like this:
If you wish to add sales as a subdomain of lyris.com, you would select www.lyris.com in the left-hand column, and then click the Add Sub-Domain button to create the subdomain. When you finish, sales.lyris.com is displayed in the left-hand column under www.lyris.com as non-bold and slightly indented to indicate its subdomain status:
