Also called: UGC denominator

The two cohorts that change every UGC statistic. Page-level = all PDP visitors (used for revenue forecasting). Engager-only = shoppers who actively interacted with UGC (used for placement decisions).

## Example

The 144% Bazaarvoice number is engager-only; our 18% median is page-level. Both are real; use the right one for the question.
