Insite | The Effectiveness Of AM/FM Radio Campaigns

This week’s Cumulus Media | Westwood One Audio Active Group blog® is an examination of Media Mix Modeling from John Fix, formerly from P&G. It explains how underspending generates weak ROI in Media Mix Modeling and the benefits of moving to an optimization mindset of, “Did this execution of AM/FM radio work?”

• Response curves depict the impact of varying levels of media investment to sales response and ROI: Underspending generates weak ROI.
• ROI varies by investment level. One snapshot of ROI does not tell the whole story: As-run data of actual deliveries have significant variation.
• Response curves tell a richer ROI story of varying levels of investment: As impressions increase, reach increases and users are exposed to multiple impressions. Because reach builds as a curve and frequency is assumed to influence consumers, there is an expectation that sales will correspond.
• Media Mix Modeling can be used to optimize within the AM/FM radio campaign to achieve the best performance.
