The number of Unique Visitors with activity consisting of two or more Visits to a site
during a reporting period.
Repeat Visitors, as a metric, is the measure of the amount of Visit activity during a
reporting period. New Visitors and Return Visitors qualifies when the Visitor started
visiting the site. It is possible for a visitor to be counted as both New and Repeat or
both Return and Repeat during a reporting period. It is not possible for a Visitor be
counted as both New and Return in the same reporting period.
For example, during a reporting period of one day, if a Visitor has their first ever visit
in the morning and then engages in a second visit in the afternoon the Visitor would
be counted as New and Repeat but not Return.
