A metric for assessing the volume of use of an online service — the number of
unique users who engaged with a given website, mobile website, desktop or mobile
application, within a given time window.

Commentary:
- Often measured on a monthly basis, though some services may use daily
measurements for increased precision and deduplication. - Some services may prefer active registered users as a metric, those
with a registered account who logged into the service (or otherwise
authenticated a visit).
