With Website Builder, you can add mobile pages for viewing on mobile devices. Pages set up with this feature will display on non-smartphone devices. For information about mobile websites optimized for smartphones, see Working with Mobile Websites.
You can add an unlimited number of pages to your Website Builder account, but can only publish the number of pages that your plan allows. If you have a .mobi domain name, you can only add mobile pages; you cannot add traditional pages. For information about adding traditional pages, see Adding, Deleting, and Organizing Pages.
