Metric deduplication lets you configure a metric to only count values non-repetitively.
|Metric deduplication||A checkbox that allows you to enable metric deduplication. Disabled by default.|
|Deduplication scope||Lets you determine how far back the unique check goes.
Session: Only the first metric occurrence of the session is counted.
Person: Only the first metric occurrence in the reporting window is counted.
|Deduplication ID||Instead of applying deduplication on the metric itself, allows you to apply metric deduplication based on a dimension instead. Valuable for dimensions like Purchase ID to apply deduplication.|
|Value to keep||
Deduplication at a person scope is evaluated by complete months in UTC time. A partial-month reporting window may not display all first or last instances, if some occurred within the full month but outside of the reporting dates.
