Your custom domain will lead to a landing page that displays the latest titles and issues for the sub-account if you have chosen that option for your base domain
Referring to the above screenshot, you can customize your landing page in the following ways.
1.) The first line of large grey text is pulled from your account’s COMPANY Name field.
You can change your company name in your profile to change what is displayed there. (See below.)
2.) The next line of text will show your Title Name, which you can also change by editing your title. (see below.)
3.) OPTIONAL: After the title name, you can include a description of your publication by adding text to the “Describe your Title (optional)” field in the edit title>basics>Search Engine Optimization section. (see below.)
