Ghost(Pro) plans are determined using two metrics: views and staff users. Find all of the current plans on the pricing page.
This refers to the number of requests to your site each month, tracked much like an analytics 'pageview'.
Your site will never be disabled if your traffic spikes. Instead, if you exceed your limit consistently over a 3 month rolling average, we'll let you know that you need to upgrade.
Staff users are the total number of users invited to your team in Ghost Admin.
Only users who have logged in at least once in the last 30 days are counted for billing purposes.
If you exceed the number of total users for your plan, we will inform you by email to let you know that it's time to upgrade, or remove some users from the Team section within Ghost admin.
