Abstract: Apparatus, systems, and methods to identify consumer content exposure are disclosed. An example apparatus includes at least one memory; machine readable instructions; and processor circuitry to at least one of instantiate or execute the machine readable instructions to detect a first exposure of a first consumer to a marketing campaign during a first time period; identify the first exposure as a first recency exposure; detect a second exposure of the first consumer to the marketing campaign during one of the first time period or a second time period; when the second exposure is detected during the first time period, identify the first time period as an iterative frequency exposure; and when the second exposure is detected during the second time period, identify the second exposure as a second recency exposure.
