Using the respondent-level frequency approach, we address the contribution of different media to marketing objectives in circumstances where the campaign has already started and for very well-established brands with high levels of awareness. Knowing respondent-level frequencies also allows us to understand if media synergy effects are truly synergistic or the result of achieving higher frequency levels among people who have been exposed to multiple media.
