We count every time a page is rendered, and this happens every time you cache a new page (or recache) an existing one. We recache pages automatically, at the frequency set in your “Cache Manager” under “Cache Expiration.” You can also recache pages ad-hoc via our API. Pages are rendered differently for desktop and mobile, so each version counts as a render. For example: if you have 1,000 URLs being rendered daily, we will count 60,000 renders per month: 30,000 for desktop and 30,000 for mobile.
