You can make as many pages (and variants of pages) as you like in Unbounce regardless of your subscription level.
 
When you first sign in to Unbounce, you are taken automatically to the Create a New Landing Page screen. This is the starting point for your new page.

Scroll through the templates under ‘Choose an existing template’ and select one as your starting point. If you want to start with a blank page, select the 'Start with a Blank Template' option. Remember, all templates are fully editable. (Alternatively you can duplicate an existing page within your account to use as a starting template.)

Give your page a name in the field labelled ‘Page Name.’ You can always change this later if you need to. Add a description if you like (this is optional).

Once you are ready to dive in, click the ‘Save & Start Editing’ button; you will be taken directly to the Page Editor with your new page loaded into it.

Note: You can create additional landing pages by accessing the Pages tab and clicking the ‘Create a New Page’ button
