For $49 per year you get four seperate pages (1 main page & 3 campaign pages).
Your Main page is what you'd use for your general artist promo page.
The address example will be: onepagelink.com/yourartistname
Your Campaign pages are bonus pages that are automatically generated when you sign up, they become a page you can use for your campaigns / releases, like the release of a new single or a new album or a tour. It's more like a live Press Release with all your assets in one simple location for media to see & use.
The address example will be: onepagelink.com/campaign/yourartistname
You can also embed private songs, if you're wanting to share or promote an unreleased song ahead of the song's official release.
Industry loves both pages, super convenient, quick and easy to use.
