Additional pages allow you to communicate the status of different products/services on dedicated pages. Each page has its own subscription under your account and can be accessed through the drop-down at the top of the screen.
You can create additional pages by clicking the page drop-down and clicking Add Another Page. The new page will be in "trial" mode until you select a payment pan to activate it. All additional pages include the features within the Business Plan until they are activated.
Sometimes you need to be able to test integrations, features, and designs outside of your production environment. If you have a need for this, simply add another page as a Public Trial and name it "Test Page" or whatever is appropriate for your use case.
Additional Public pages are free and remain in "trial" mode until you activate them, meaning only Team Members can view the page while logged in. You'll only pay for the additional page if you decide to activate it.
